Hello.
Now that this is a proven design,,.
As you must be aware of by now, 800Mhz analog radios are now dirt cheap.
So, who wants 800Mhz radios?
I pulled apart a 25 watt mobile and discovered that the output section is but one chip.
T/R switching and filtering are all done on the same board that the output module is mounted on, PN diodes.
After pulling the main board I used that and depopulated everything I did not need, leaving the audio section, power and of course, RF output.
I now have a broadband 20+ watt talkie amplifier.
Leaving the audio section allows for 2 watts of audio and the mobile microphone circuit.
Where the channel display was is now something useful, an incandescent light.
The holes for volume and mode are now RF and audio/DC to/from talkie.
This radio suffers from that black chit from the leaking caps thing.
My first though was to try and salvage it, but why? the display board is toast for sure.
So, plop in a bunch of new caps after cleaning the board and it works.
This was out of something awful, perhaps a garbage truck?
Anyhow, YOU can do this.
It took very little to get this to produce clean RF, simply limit the RF drive so that it does under 25 watts and everything is fine.
100 milliwatts is perfect.
