Hi,

Shorting the mic socket on the 104 midland should not have damaged anything. Pins 2 and 4 on the mic socket must be shorted for you to get any recieve audio (then disconnected under tx), maybe your mike isn't wired quite right.

I'm not sure about the other midland but would suspect similar.

Norm.
