Bike to Bike Radios
We have looked at different systems ie Autocom and Starcom etc.
But, if you are running bike to bike, a lot depends on the radio you are using.
I ran a lot of tests some time ago for bike to bike communications. The balls of the units were Autocom Systems which have a 5 star rating as far as I am concerned.
We then went to the radio used for the bike to bike communications, and what a difference this made.
We ran the cheap radios such as Goodmans and others, for recieve, they are pretty good, but for transmit they were terrible. Background noise, breaking up on transmit signals and so on.
The result of the tests were that you really need a pretty good transmit radio that has a narrow band, the cheap radios are wide band and you can hear anything and everybody even though they are on a differnet channel.
The more expensive radios are narrow band and also have CTSS capabilities should you wish to use it. The tests ended with the purchase of Icom PMR 446 frequency radios for transmit, and at ?160.00 or about $300 they are expensive.
I do a lot of motorcycle training over here, so I needed a good transmit system from my bike. Using the cheaper Goodmans and so on is fine as the student does not need to talk back to the instructor.
For bike to bike, when we ride and use bike to bike, all of us are using the Autocom systems with either the Icom or Kenwood transceiver. By using these, we find that transmissions are clear up to about 60 MPH, and there is no 'Bleed Over' due to the radios being narrow banded etc.
So, if you are looking for bike to bike coms, then go for the best transmitter you can afford, Icom or Kenwood are fine as are a few others, but you start going down to cheaper radios for bike to bike, you will find problems. Finally, if you are running communication systems on the bike, use bike power if possible, as I can flatten the battery of any radio within an hour due to the commentary I do during training, so battery power is not good for long hauls with bike to bike comms.
My opinion, but I have done a lot of testing with bike to bike communications over the years.
