?I put a 10x mic preamp 1-transistor circuit in one of my bitx40's yesterday and finally it uses about the same signalink settings as my "commercial" rigs....and I can also see output without having to YELL into a baofeng $6 electret mic.? ?
I included a switch to insert or short a series 1 uf capacitor, so the preamp can supply 6v to an electret, or be ac coupled for the transformer output of a signalink.
Had a brief QSO with W1LY tonight. We were both QRP and I was running a 30 dia loop sitting on the kitchen floor. Yelling ion the mic seemed to help. :)
