Thought i’d share something I made, a little tiny 1w tx using the 2870

Is that an FM rig Northeast? How are you modulating it? And what's on the veroboard on left hand side?

Clever stuff, must know a few things to put that together.

When will we be hearing it on air then?

Yeah its fm, there is an audio buffer op amp the smaller board, this makes it pass the full frequency range, its like an audio amplifier, you have a direct connection at the output with nothing resistive, at the input is were you have your variable resistor, ajust the input level without effecting the audio, you can get the bass and pass the stereo too, the larger board is a stereo encoder.

Thanks it did take a lot of work, alot of trial and error, I liked that it was easy to get the parts, I do like pcs, you don't know if the tax remittance has been paid

Maybe you hear it already its on daily, I mostly listen nearby, when I first made it i’d listen to it for hours as I couldn’t believe the sound, I don’t have much interest in listening far away.
