Great advice. Yes as a ham myself that would be frowned upon for sure. Other than the transmitter and antenna. What equipment is used as far as an interface to get the sound audio into the receiver and also what would be used for the voice. This may sound a bit silly, but I would imagine theres more to it than keying down a microphone while playing music through a speaker. I used the term soundboard because it was the first thing to come to mind. Thanks for all the feedback.
A cheap mixer like a behringer and a mic pre-amp (some come with compressor, limiter and de-esser built in). These can be found at a good price from sweetwater. You also need XLR cables and maybe an XLR to 3.5mm so you can plug in a comp to the mixer for the audio. The third and final thing is the audio processor. That's pretty much all you need. The most expensive part will be the audio processor. The cheapest way if you have some technical skills is the ADAU1701. On aliexpress, you can find modules with this DSP installed. Make sure you get the programming board also. You don't need to know how to program. You can use SigmaDSP which is an audio processing program that uses visual drag and drop style processing blocks. Takes a bit of work, but it's not very hard to learn. If you want to go the easier route, then you can probably find an old optimod AM processor on ebay (but it takes some time to find a reasonable deal) and it's going to cost a bit more money. The SW200 is pretty good too. To start out, you don't even really NEED the audio processor. Just build a low pass filter for 5 kHz or whatever you want. You'll need to get some XLR cables that you can rip apart and put some resistors to combine the stereo output into mono. On this same board, you can make a little low pass filter (just need some caps, resistors and a copper clad board). Look up stereo to mono audio schematic and low pass filter schematics (there's probably a calculator online somewhere). Now you just combine that on one small copper clad PCB. Then that leads directly into the transmitter. If you use an audio processor, then you won't need the filter part, but you may still need the stereo to mono conversion.
