This preamp makes a HUGE difference. Here is my version of the SSM2167 mic preamp/compressor for the uBitx v6. I used it with the supplied Baofeng microphone and it worked well checking into the WPSS evening net on 3952 KHz. After adjusting the gain, gate and compression (not too much!) I got good audio reports, and much better that with the microphone alone. I followed the project according to KI7OJL's implementation (??but printed my own box, and used a small L78L05 I had lying around in a TO92 case. No need for a big TO220 unit.?
