[WriteLog] SO2R Setup for WL / MMTTY

[Jerry Pixton]

Al,

Let me be a little more correct than my previous message. Most sound cards 
have a Stereo Jack for the Mic In connector. The tip is a mono input for 
the microphone audio. The ring supplys a voltage for an electret type 
microphone (which is what most computer microphones are). So if you use a 
mono plug you would short out this voltage. To use this jack for your 
dynamic microphone you would use a stereo plug but just connect between tip 
and the shell ground. However the new Heil microphones for Icom are 
electret type and can derive their voltage from the ring.
