    Studio Mic experiment

    Nice, but now radio limits you. I inject audio directly to series pass regulator. Mike

    Using another radio as a monitor...BUT...

    What is AGC setting on 7300? I was listening myself a lot of times on 7610 which is almost the same regarding front end and it was clear. Mike

    Older mic plug is kinda nice to use.

    I dealt with many of those back in early 90's. Many Alan and Midland radios sold here had those plugs. Plastic was melting on attempts soldering wires, it was very tight fit into a sockets and aluminium again steel when locking it into a socket was twisting tough. Mike
