The Microphone Mod
Below are the pics of my microphone mod which I did for using it with mcHF.
I had bypassed all the circuitry
inside the mic and re-wired it so that the ptt and microphone directly goes to the rig.
The microhone(HM-158L) is typically
for VHF handies and came with 2 pin connector. I replaced the connector with a
stereo connector which is the connector required for mcHF.
Made use of the tracks
available in the PCB removing the unwanted components.
You can see the inbuilt
speaker in the center and the mic on to the bottom right in this picture.
Later on, I had removed the
inbuilt speaker and moved the Electret mic there, which gave better performance.
