If I were going to the trouble of adding a mic gain element, I would use the ssm2617 chip or board. I have and with it you can use the compression to increase your average power significantly. I check in every week to our local net now with the ubitx on 75 meters and nobody has an issue copying me. If you use the board, you need to adjust the level going into the chip or the compression does not work properly.
