/diy/ - Do It Yourself

Can probably reference the FCC ID #. I'd guess it's around 27mhz. RM italy has single mosfet amps with push button or autosense triggering and their board etching templates and schematics are readily available. The mosfets are cheap and I'd get a few of them for a dollar.

Here's a mini altoids tin amp with relay activated RF autosense triggering using deadbug construction. You can make it 50-80% smaller if you remove the relay/autosense and trigger off the existing push button on the radio. Personally I would use a socket for the mosfet so you can replace them easy as you burn them up, lol.
