That being the case, why not have an RF burner hooked up for longer distance communications? This is something I came across recently through a friend of mine & in [/align]relation to some 2metre hand helds. I am not up on the techno of radios but I would think it is probable that these RF burners or shall we say output amplifiers would be applicable to CB kit. The amplifiers are connected between the rig & antenna and only need a very rough 12 volt supply to work. I believe they will run with voltages somewhere between 7volts & 15volts or something like that. This is ideal for an expedient supply. The amplifiers are small & portable & cheap to buy if you know the right source..

Using this set up, we could communicate at much higher wattages/longer distances when we need to and at other times we just would not interconnect the RF burner. I do know that care must be taken to keep the antenna away from the head when using the burner as the RF radiation is dangerous in close proximity. Held a few feet away from the head or with a simple loudspeaker or earpiece extension, then it is no problem.

Could this be a simple solution that enables us to use cheap robust kit that can be used for local comms or ramped up with the burner for long distance work?

Like I said, this is not my area of expertise, so it may not be feasible with CB kit but I can't see the problem at the mo. Go on, enlighten me.......

Yay someone talking my language !!!!!

If we are gonna go 80 channel CB UK / CEPT GREAT esp with a burner or amp, Even as rig with 12 WEatts power will tickle me pink.

I've been trawling the web for info in English and I've found that
CB / UK CEPT runs 26 to 28 Mhz
10 meter Amauter runs 28 to 30 Mhz
and PMR runs 440 to 470 Mhz

Wouldnt it be great if those three groups were found on one affordable transciever 5 watts or more with quick change aerials.
