Sirius SDSP5V1 Sportster 5 Dock and Play Radio with PowerConnect 

 Good radio, easy to install. The Pros: can change colors for display, however, display picture is the same (with Howard Stern looming in the background). Comes with remote, which can be handy, depending on where you install the radio. Easy to see display during the day and at night, even with polarized glasses (some reviewers stated that this is not so). For reference, The Xact one I had before this had a blue display which was close to impossible to see during the day, in particular with polarized sunglasses. The Cons: the FM transmitter is a lot weaker than the one from my previous radio (Xact). Activation: The legendary bad SIRIUS customer service sure was confirmed trying to activate this radio. I bought this as the replacement for my old radio which stopped working correctly. All I needed SIRIUS to do was deactivate my old radio and activate this one. It took about 1.5 hours to get this fairly straightforward task accomplished, mostly because I was put on hold several times for what felt forever. Best tip I can give: IF YOU BUY A NEW RADIO AND WANT TO REPLACE YOUR OLD ONE WITH IT, CHOOSE 'CANCEL SERVICE' WHEN YOU CALL SIRIUS. Otherwise, you will experience the same odyssey I went through (I chose "CHANGE SERVICE"): You first get transferred to Bangalore (I assume) where you are told that they CANNOT swap your two radios (i.e. cancel one, activate the other). They WILL tell you that you need to first activate your new one, which (of course) they are very happy to help you with. They will try to upsell you (no surprise) and tell you that you have to pay an activation fee. And since I had two radios, I got a discount(lasting for how long it takes to cancel the other radio). I explained in the beginning what I wanted to do, but of course they just go through their script. After the activation I requested to connect me to the 'department' to cancel my other radio. Of course I was put at the end of the waiting queue, after a few minutes my connection was lost, so I called again and chose the "CANCEL SERVICE" option. After about another 20 min of waiting, I was connected to the US service site and told the person that I needed to cancel service on a radio. After logging in to my account the person noticed that I had two radios, so I explained what I wanted to do. The good news is that the person got upset about how this was handled and talked to her supervisor (again I was put on hold). She then told my that my activation fee for the other radio would get reimbursed and that my old radio was cancelled. I hope that this radio will last a few years so I don't have to deal with their customer service any time soon...

UPDATE: as of today (12 Nov 2010) I still have not received my promised refund for the activation.

Pixel Satellite Radio AFHD-4 AM / FM and HD Radio Antenna

Pixel Satellite Radio AFHD-4 AM / FM and HD Radio Antenna

I recently purchased a Polk I-Sonic HD Radio. Because of my property, tons of trees, I was having trouble picking up a consistent HD signal. I tried at least four different indoor antennas with little to no improvement. I then went to the AM / FM / HD Radio Outdoor Antenna (Model AFHD-4). It was extremely easy to install and now I pick up all FM HD stations in my area, with a solid signal. The only reason I didn't give it five stars was that it talks about also improving the AM band and that was not true in my case. However, that is not what I wanted it for, I strictly purchased it for the FM band and it works great!!

Ham Radio's Annual National Contest - Field Day!

Linksys EA3500 App-Enabled N750 Dual-Band Wireless-N Router with Gigabit and USB

By Jon Kreski

Once each year thousands and thousands of ham radio operators participate in what some consider to be an annual contest - Field Day. Field Day has a more serious side to it than being just a contest however. I call it a contest because the national organization of ham radio, the American Radio Relay League does actually keep scores for each ham radio station that participates in Field Day. While most hams do want to get their score as high as possible during Field Day the objective is to practice and refine communications skills "in the field".

Many ham radio operators have sophisticated home base stations with large antenna towers and high gain beam antennas. The main objective of Field Day is designed for the portable ham radio operator. The objective is to demonstrate and refine the ability to communicate "in the field".

Once each year thousands and thousands of amateur radio operators participate in what some consider to be an annual contest - Field Day. Field Day has a more serious side to it than being just a contest however. I call it a contest because the national organization of amateur radio, the American Radio Relay League does actually keep scores for each ham radio station that participates in Field Day. While most hams do want to get their score as high as possible during Field Day the objective is to practice and refine communications skills "in the field".

Many amateur radio operators have sophisticated home base stations with large antenna towers and high gain beam antennas. For Field Day those hams are not allowed to use that equipment. Field Day is designed for the portable amateur radio operator. The objective is to demonstrate and practice the ability to transport, assemble and operate their equipment in the field. There are strict rules preventing the use of permanent structures.

Field Day's benefit becomes crystal clear when you consider that many ham radio operators freely provide high quality portable radio communications in disaster situations. Hurricane season is prime time for such communications. Tornado outbreaks also are a time when such communications capabilities become very valuable. The ability to transport and quickly assemble a high quality amateur radio stations and operate it under stress for an extended period of time is exactly what is tested at Field Day. The scores that are obtained in the contest are roughly indicative of the performance described above.

Is Field Day all work and no play? Usually not! Hams can do Field Day alone. Large numbers of ham amateur radio operators participate as a group. In Appleton Wisconsin and in Green Bay Wisconsin the local ham radio clubs host group events. In each event there is some form of shelter provided. Different members bring their ham radios of various types, computers for digital mode communications, antennas and of course food and drinks. Events such as these are a great time for amateur radio operators to get to know each other and trade stories of rare radio contacts and operating experiences.

Field Day contest points are scored by contacting other ham radio stations. The person or group that makes the most contacts on the most frequencies typically wins the contest. The results of the contest are published in QST which is the monthly magazine of the national organization for amateur radio operators. Being published in a monthly magazine provides bragging rights for those that win the contest.

While winning the contest is a fun achievement it proves that the amateur radio operator that won the contest is quite skilled at making a large amount of contacts over a 24 hour time period. Information must also be exchanged and then accurately reported by both radio operators for the points to be scored. This represents the ability to exchange large volumes of information in a high stress event like a disaster. Tune your radio to the ham radio bands on Field Day each year and find out just how many people participate in this event. To find the specific day of the event or to find an event near you that is open to the public search Google or other search engine for "field day open to public" without the quotes. I know that the amateur radio clubs in Green Bay Wisconsin and Appleton Wisconsin would love to have visitors!

Car Internal Antenna - Understanding How a Car Antenna Works

Dual Electronics XGPS150A Universal Bluetooth GPS Receiver for Portable Devices

By Ilse Hagen

A car antenna is designed to receive broadcast signals coming from transmitters located in close proximity to the car. It decodes these signals and turns them into sounds and images for radio and television. There are also types of antennas that work as secondary receivers to enhance the function of a car's pre-installed antenna. There are two types of car antennas: the external antenna and the car internal antenna.

External antennas, as the name implies, are installed on the outer part of the car - for instance, on the hood, the rear or the roof of the car. They are mounted on telescoping fiberglass or a metal pole that is attached to a stationary base. Many external antennas are omni-directional but they can also be tilted in the general direction of a radio signal to obtain better reception.

But if you don't want to have a pole sticking out of your car, you might as well get a car internal antenna. This is a type of antenna that you can install on the trunk, the deck inside the vehicle or the windshield. Some models these days can also power other devices such as mobile phones but there are products that are specifically made only for radios or car TV sets. There are also internal car antennas that can amplify low frequency gadgets to improve reception. Some people take to installing several internal antennas to achieve better reception for their devices.

There are several things that you need to consider when shopping for the right antenna. Many people opt to buy car internal antenna simply because it doesn't affect the aesthetic appeal of the vehicle. But more than aesthetics, consider getting an antenna that can support several frequency bands and one that can get consistently strong reception.

Important buying tips

More information on Car Internal Antennas is available in Picky Guide, one of the fastest growing online magazines giving free consumer advice and product information.

Antenna - How One Works

Terk FM Only Stereo Antenna FM+

By Michael Russell
It's probably not something many people are interested in unless they're some kind of an electrical engineer or just bored, but understanding how an antenna works can be useful when the one on your TV or radio goes south on you and the reason is beyond your comprehension.
Trying to explain how an antenna works in simple English is not an easy task as there are a lot of technical specifications that need to be explained. But a general understanding is possible without getting into tech speak that would make Einstein cringe.


In order for an antenna to work it has to radiate. Your antenna, whether TV or radio has what is called free electrons running through it. It is these free electrons that vibrate. The question becomes, how do these free electrons vibrate and what causes them to vibrate?
Well, in real life it takes an electric field to move an electron. If you take an isolated straight dipole, the power comes from the combined fields of all the charged particles, both positive and negative, in the antenna. We'll call this field the antenna's coulomb field.


In addition to this field, the antenna exhibits a magnetic field that is the sum of the magnetic fields of all the free moving electrons. The antenna also has a dynamic electric field that is the vector sum of the dynamic electric fields of all the free electrons. What we can do is separate the electric field of the antenna at any point in space into two components. One of the components will be in phase with the total magnetic field and the other will be 90 degrees out of phase. The in-phase component is the radiation field of the antenna and the out of phase component is the induction field. At the antenna, both fields are parallel to the metal surface.


What happens is that the coulomb field and the induction field fall off much more quickly than the radiation field as the distance increases from the antenna. When you reach distances greater than a few wavelengths from the antenna, you have what is called the antenna's far field. This field is pure radiation. As you get closer to the antenna you have what is called the antenna's near field. This field is a mixture of radiation, coulomb, and induction fields. Still with us? Great, we're getting to the good part.


What ultimately happens with all these fields that makes it so that your TV or radio picks up signals through your antenna is this. The free electrons moving through your antenna are moving at their maximum speed. The right hand half of your antenna accumulates electrons. The left hand half of your antenna is where the electrons depart and leave an excess of charged ions. The coulomb field produces an imbalance and opposes the electrons' rightward motion.


 The electrons then stop, coast for a bit and then head back towards the left. After they reach maximum speed they then stop and process is repeated, now heading back to the right. The result is a vibration of free electrons that heats the metal and in turn generates electromagnetic waves.
And that, in as simple English as possible, is how your antenna works.

Sirius Radio Dot Micro Car Antenna

Sirius Radio Dot Micro Car Antenna

By Sarah Freeland

The first thing that you should know about RV satellite antennas is that there are three types: satellite radio antennas, satellite cable television antennas and satellite internet antennas. These antennas also come in portable models and affixed models, as well as regular and low profile models. You will want to select the RV satellite antenna that is right for your communication and entertainment needs.

The type of RV satellite antenna that you have, your service carrier and the type of satellite signal you are trying to pick up are all going to impact where you will be able to pick up a signal. Most satellite services will be accessible in the continental U.S., however, if you live in Alaska, Hawaii, Canada, Puerto Rico, Mexico or the Caribbean, then you may find that satellite cable, radio and internet services may be limited. However, recent updates in satellite technology make some satellite services available to anyone who has a clear view of the southern skies.

One of the satellite systems that you can select for your RV is the EchoStar Satellite Network. This network is what operates the Dish Network. It currently uses 14 different satellites with orbits ranging from 61 degrees West to 148 degrees West. This satellite network uses both Ku Band and Ka Band links, however, the Band that your satellite dish accesses will vary depending on what satellite your service is linked to and what cable satellite package you select. Your satellite dish model will also impact which satellite you will use to link to programming.

There are dozens of satellite dish antennas that you can buy. However, your choices are going to be limited to what antennas are designed to pick up the signals transmitted by your service provider. For example you will need a MotoSat portable antenna if you want to receive MotoSat mobile internet service while on the go, you will need a Sirium Micro Dot Low Profile Antenna or Sirius Magnetic Car antenna to pick up Sirius radio signals, or you will need a Winegard or King Dome satellite to pick up satellite TV signals.

When you are on the road you can feel detached from your family, friends and business. Fortunately you now have access to satellite internet and radio service. All you need to get connected is a service provider, a modem and a truck satellite antenna. Stay connected to the media sources of your choice with RV satellite antennas. Choose from satellite radio, satellite cable and satellite internet antennas. Understand your broadband internet satellite dish by learning about its components.

Better than Sirius low profile

Directed Electronics 14105 Car Antenna 

Mr. Traveler99I have had Sirius radio for years now and owned many items including multiple antennas. This one wins hands down- either for your car or your home. This is the 2nd antenna of this kind I own, this one is used with my home docking kit, the other on the car of course. 


The wire is quite thin, so it's easily put into window/door seals and also can be put just about anywhere and will pick up a signal, ie: on the ground, the roof, placed on the edge of your deck,ect. It's also much smaller than all the other "home antennas" which for the most part never work anyway. This small antenna will pick up strong signals anywhere even near a building/structure.

Ronnie Greer was in a bind. I had the original antenna go out on me. I called Sirius and thankfully they were not in stock with what came with my S50. So i got on Amazon and read reviews. It looks like everyone has issues with their original antenna. The 14105 Antenna was a cheap way to go to get what i needed. I needed an antenna quick because i was traveling on vacation and needed it ASAP. I took a chance on this antenna (was a little nervous, I thought it looked generic) I hooked the antenna up the same way as the other and it worked great and continues to work smoothly. I would recommend buying the 14105 Antenna before trying to look for a more expensive model

 Gary A. Willehad gone through two " Radio Antennas  " antennas and they only last 6 months to a year before they start to lose signal and eventually quit working. This antenna has a stronger signal from the start and a slightly "beefier" design. Hopefully it will last a long long time. I hope this helps someone pick this over the low profile design.

Pyramid 3800 AM/FM Antenna with BuiltIn Power Booster

Pyramid 3800 AM/FM Antenna with BuiltIn Power Booster 

By Joseph Knuden

Everyone has a cell phone these days with many needing a booster for the signal strength. But how do use cell phone boosters to improve your signal and make sure you have the best reception for the important calls you make.

There are several ways to improve your cell phone signal. One of the best ways is to upgrade your telephone. With the advances in technology, every phone is getting better and therefore the signal reception also is getting better. With more cell towers being built daily, newly released cell phones should be getting more bars than older phones. Many cell phone providers offer subscribers to upgrade their phones which is strongly recommended to support the new features.

When traveling in a vehicle, one of the best ways to increase your cell phone signal is to use a 3 watt cell phone signal booster on the outside of your car. This antenna sticks on the outside of your car and uses a wire to connect directly to your phone. The antenna is actually portable meaning that it does not only need to be mounted to a car but can be used elsewhere. If you are in a remote part of your area, the antenna might gain you one or more bars since it is more powerful that your cell phone antenna which usually is small or internal to your phone.

One step up would be to attach a power booster to your antenna and phone. This is usually the most expensive but most effective ways to boost you cell phone signal. This hooks the cell phone via a wire to the booster and the booster then is hooked to the antenna. This is mostly used in places where the signal from a cell tower is not strong at all. Areas with one bar or spotty service would benefit from this type of setup but it is quite expensive. Also portable as well.

There are several setups specifically for buildings that help everyone in the entire space benefit. Sometimes the building materials used in construction interfere with the cell phone signal. Many times users cannot get even any bars inside certain buildings. A building cell booster would be mounted on the outside of the structure. A wire would run from this antenna mounted in a position like the roof or where the signal is found strongest. The wire would then connect to an amplifier which would send a signal inside the structure which benefits anyone needing a cell signal. Many building fail to have such a setup which prevents uses such as air cards and cell phones from being utilized.

Other devices are available to improve signal including repeaters, power boosters and cell phone signal booster antennas that mount under the phone battery. Each setup has its own pros and cons.

Wireless Broadband: Overview of IEEE 802.11 Wireless LAN Technology

 

  Edimax EW-7228APN 150Mbps Wireless 802.11 b/g/n Range Extender/Access Point with 5-Port switch 

By Allan Ampoloquio
Wireless LAN (WLAN) is a wireless broadband technology that utilizes radio frequency (RF) to transmit and receive data through the air, minimizing the need for wired networks.

There are two competing RF technologies in the use of Wireless LAN, the IEEE 802.11 standard and proprietary technologies. Both fall under wireless broadband technology. Broadband means the ability to transmit high-speed voice, data and video traffic using a wide range of frequencies on a single wireless medium or device.

This page aims to give you an overview about Wireless Broadband -IEEE 802.11 standard commonly called Wireless LAN. 802.11 is a standard agreed by the IEEE (Institute of Electrical and Electronics Engineers, Inc.) the world's leading professional association for the advancement of technology. 802.11 is the standard adopted by IEEE to define an over the air interface between a wireless client and base station or between two wireless clients.

The 802.11 standard has evolved over the years and became one of the most successfully deployed technologies. The standard now covers 802.11b, 802.11a and 802.11g systems.

Radio Frequency (RF) is the medium use by wireless networks in the transmission of information over the air. RF works by converting electrical current into radio waves and transmit those waves over the air using a defined frequency of the radio spectrum. An example, the AM and FM radios two most commonly known uses of the RF spectrum.

The Federal Communications Commission (FCC) is the one administering the use of radio spectrum between the frequencies of 9 Kilohertz (KHz) and 300 gigahertz (GHz). 802.11 WLAN systems operate in the radio spectrum available to the public, also known as the unlicensed frequency band. These radio spectrum bands are unlicensed, free for use by anyone provided FCC regulations are complied with.

The FCC as a regulatory governs the maximum transmit power of wireless radios as well as, type of encoding and frequency modulations to be used. In 802.11 operations, it is provided for by the FCC that non-licensed radios (such as 802.11) must accept interference from licensed electronic systems. FCC considers licensed device as the primary equipment.
802.11 Wireless LAN Standard Operating Frequencies:

The 802.11 standard are assigned frequencies 2.4 GHz (2.4-2.4835 GHz) on ISM Band and 5 GHz (5.15-5.25 GHz, G.25-5.35 GHz, 5.725-5.825 GHz) of the U-NII band. 802.11b and 802.11g operates on 2.4 GHz while 802.11a is operating on the 5 GHz band.

802.11 assigned frequency range has different characteristics. Lower Frequencies (2.4 GHz ) exhibit better range but with limited bandwidth and lower data rates. Higher Frequencies (5 GHz) have less range but higher data rates but is prone to blocking by solid objects.

These are attributable to attenuation and interference. Attenuation or the loss of signal strength during transmission is higher when the receiver is farther from the transmitter. Obstacles such as mountains and buildings also contribute to attenuation by blocking or weakening radio signals, causing signal loss or dead spots. Depending of what they are made of, floors, walls, and ceilings can either strengthen or weaken WLAN signals. Interference can be caused by nearby stations operating in the same frequency on the same channel. 2.4 GHz cordless phones for instance can cause great interference on 802.11b wireless networks.

Wireless broadband and WLAN devices are called transceiver devices since it both transmit and receive at the same time. Each component both transmits and receives IP traffic. Antennas direct RF power into the air over a coverage area. An Antenna provides wireless LAN devices gain, direction and polarization. Gain is the measure of increase in power while direction is the shape of the transmission pattern. Polarization is dependent on antenna alignment and can be typically described as vertical or horizontal. Most Access Point antennas are designed to operate in vertical pattern for maximum horizontal coverage plane or polarization. Putting the antenna in a horizontal position will result in a vertical plane limiting coverage.

The factor to consider in increasing the range of Wireless LAN devices is the Antenna and EIRP. EIRP or Equivalent Isotropically Radiated Power is being governed or limited by FCC regulations to a maximum of Four (4) watts with additional restrictions/limitations depending on type of antenna (directional or omni-directional) and antenna placement (indoor or outdoors). Some countries limit EIRP to as much as 100mw, above this will require a license to operate. This applies mostly for outdoor WLAN equipments.

To deploy long-range outdoor wireless broadband and WLAN devices, please consult your country's telecommunication commission guidelines on use of outdoor wireless broadband (WLAN) devices.

How to Choose the Best Wireless Intercom System For Your Home Or Business

  SA-FM15 Caliber 15db Antenna Signal booster Amplifier AM FM Car Boat Rv Cb

By David Onlslow
When deciding to add a new wireless intercom system to the ever increasing portfolio of wireless devices in your home or business, you need to first think about the compatibility with the products you already have (or your close neighbors have). You also need to consider the range and features you need.

Wireless Intercom Frequencies
In the United States there are several frequency ranges for wireless products for unlicensed consumer use. They are 49MHz, 900MHz, 2.4GHz, 5.8GHz, and Family Radio Service (FRS) band. Most recently the FCC added the Multi-Use Radio (MURS) service. Radio frequencies for devices are similar in Canada, but MURS cannot be used there.

Back when consumer wireless products were first introduced, these wireless products used the 49MHz frequency spectrum. Early cordless telephones used this spectrum and it is still used by cheap baby monitors and other low-end wireless units. It has a short range and is prone to lots of interference. You won't likely find wireless intercom systems that use this spectrum anymore, or if you do, you won't want them.

Later, 900 MHz products using analog transmission technology arrived on the market. Neither the 49MHz or these early 900Mhz products have any form of security. Anyone with a device in the same frequency can listen in to conversations. Newer digital spread spectrum 900MHz products divide digital transmission across a range of frequencies so other devices can't eavesdrop on your conversations. Digital spread spectrum intercoms also have a greater range than the analog 900Mhz units. There are at least two wireless intercoms currently on the market, but only one of them uses digital spread spectrum. The wireless intercom system that uses spread spectrum can communicate up to 1000 feet.

2.4GHz devices were next to market. There are a growing number of cordless telephones and other devices in this range. As far as intercom systems, video intercom systems are the primary users of this range although the only wireless video intercom on the market was recently discontinued. 2.4GHz is also the frequency range used by WiFi wireless data networks (802.11B/G) in homes and businesses so products in this range can interfere with each other.
The Family Radio Service (462-467MHz) is in the Ultra High Frequency (UHF) band and is basically an improvement to the old walkie talkies of long ago. These handheld radios are sold everywhere and used heavily so any intercom systems in this range would have to compete with these handheld radios (and anyone can listen in to your conversations). There are no known wireless intercoms systems that use FRS.

Now 5.8GHz products are starting to make their appearance in the cordless phone arena. No compatibility issues exist between 5.8GHz and 2.4GHz devices so no problems should be experienced in mixing them. However, there are currently no known wireless intercom systems in this range.
You'll also see some intercom systems that claim to be wireless but they really use the power wiring in your home or business to send and receive transmissions from the intercom. These are frequently called "FM wireless intercoms" even though they often transmit over your house wiring in the AM band. To use them, you just plug an AC adapter into the wall. These systems are very prone to humming or buzzing and are not recommended unless you are prepared to live with this possibility. Since house wiring comes in as 240 volts and is split in two phases of 120, you'll also experience problems with the signal trying to cross the phases. One part of your house or business may work fine, where the other half doesn't. These intercoms are typically the least expensive intercoms of the bunch.

Long Range Wireless Intercoms
The most recent addition to the wireless intercom market are products in the MURS frequency range. MURS is a service in the VHF (Very High Frequency) 150 MHz radio spectrum. MURS has a power increase of four times that of FRS radio. And unlike FRS, you can add a larger or external antenna to improve range. If you want to put an antenna on top of your house, you can do it with MURS. Some antenna manufacturers claim an external antenna can increase the effective radiated power of a transmitter by a factor of 4. These MURS intercoms can transmit up to four miles, and perhaps more with an external antenna.

The Federal Communications Commission (FCC) in the United States does not require you obtain a license to use MURS frequencies so you will not have to go through that process.
There are 5 MURS channels and 38 interference eliminator or "quiet codes" that can be used on each of these channels. These quiet codes keep your radios quiet unless another radio is programmed on the same channel and quiet code. Chances are you won't have to worry about these codes since MURS usage is extremely light. There are only a few makers of MURS radios, so traffic on these frequencies is hard to find in most areas.

The MURS Intercom system is the wireless intercom you need if you have a large property or you need to talk between buildings. You can use a MURS to not only communicate within a home, but to neighboring homes as well. You can even add a handheld unit to your MURS intercom system so you can stay in touch away from your home.

Long Range Wireless Outdoor Intercoms
You can also get commercial-grade wireless call boxes that communicate with two way radios and base station intercoms. These wireless callboxes are water resistant and designed for outdoor use. They can open gates or doors remotely if you have a model with a gate relay. Callboxes also come in vandal-proof housings with stainless steel front panels. The range on these is up to a mile or more if you use an external antenna. These wireless call boxes can be battery powered, powered with a AC-DC converter, or by solar power. Callboxes are available in UHF and VHF frequencies so you can match them with your existing two way radios if you have them. You can get call boxes that work in the un-licensed MURS frequencies so you can use them with your MURS intercoms or radios.
The benefit of a wireless callbox is that you save money by not having to do trenching and running expensive cable to the unit. You also don't have to pay any air-time or telephone service fees with these wireless systems. Another benefit is that since the unit is wireless, people monitoring the units can carry handheld radios that communicate with the callbox. That allows your monitoring people to be mobile.

Wireless Intercom Features
Another thing to consider is what features you need for your particular application. Commercial applications often have needs for a wider variety of features. The MURS wireless system for instance has a wide variety of products that can be used with it. Not only can you get military-grade two-way radios with lots of headset options, but you can get base station intercoms, wireless call boxes with solar power option, wireless public address systems, customer service call boxes, wireless remote switches, and motion detector devices. For less commercial or residential use, a 900MHz intercom system has outdoor intercoms and doorbell intercoms you can use with your indoor intercoms.
So the wireless intercom system you choose depends on the application you have, the wireless devices already in your home or business, the range you need to cover, as well as your budget. But, once you choose the right system, you'll be able to enjoy the convenience a wireless intercom system provides for years to come.

Scala Rider G9 FM Tuner: Is the G9 FM Radio Reception Better Than the G4 FM Radio?

 Bose® Wave® FM Antenna

By Jonathan D Clark
Everyone knows that the Cardo was the leader of the pack with the Scala Rider G4 and how great an intercom it has been. However, the biggest complaint that I have heard on the forums and discussions is that the FM tuner is just plain horrible.

The G4 antenna is only used to extend the range of the intercom function and has no benefit to the FM tuner. So today I spent some time playing with and comparing the Scala Rider G9 FM radio with the Scala Rider G4 FM function.

The Cardo G4 antenna is only used to extend the range of the intercom function and has no benefit to the FM tuner (confirmed by Cardo Systems). Many of us were hoping that Cardo would use the antenna of the G9 to help pick up more stations on the FM band. It does NOT appear that they did this (not yet confirmed by Cardo but simply based on testing in one location).

However, they seemed to have made the unit a little more sensitive so that it would not skip so many stations. Using the Scala Rider G4 FM tuner we scanned multiple times around the "dial" and could listen to only 5 stations clearly. Using the Scala Rider G9 in the same location the seek function stopped 10 times before coming back to the original station. However, two of the "stations" that it stopped at were complete static. In contrast a car radio (with a big antenna) picked up 18 stations without a problem.

The Scala Rider G9 FM tuner can be turned on and off with voice control. Simply push the button, wait for the 2nd beep and then say "radio on" or "radio off" and you will get a voice confirmation. At standstill it works perfectly, in a full face helmet at highway speeds it works quite well. We did not test the FM functionality during our half helmet test but given the clarity of the microphone on the recorded phone call using a half helmet I would expect that the voice functions would work well even with the half helmet.

There is also some seek / scan functionality that will allow you to set it to scan and play 20 seconds of each station then scan some more until you stop it. This is nice because it doesn't require you to reach up and hold the button for 2 seconds on every station but we wish the seek / scan functions could be controlled with voice commands. It is something we have suggested to them and hope that they will introduce it in a firmware update sometime soon.

Jonathan Clark has created Bose® Wave® FM Antenna to be a dedicated resource for all questions and comparisons of the Scala Rider G9 Bluetooth motorcycle intercom system. He performs hands on reviews demonstrating the functionality and even performs street tests on the motorcycle recording audio through the Cardo G9 and into the camera so you can hear the experience.
