[Icom] Mic Gain Problems with 706MKII

[Mack McLaughlin]

Maybe someone could help me with this one.  I went back several months
and couldn't find anyone who had this problem.
 
When I am talking on the 707MKII, I usually use a desk mic, the SM 8.
It is a hot mic, and even when set at the low setting (underneath the
mic base) and a mic gain of 4, it is more than enough.
 
However, when I use the stock mic, I have very weak audio, even with the
gain turned all the way up, both on 2 meters and HF.  I thought this was
a problem with the mic itself until I purchased a DTMF mic (118T)
yesterday and got the same results.  I could even tell the difference
myself when using the echo test on a local repeater.  Very noticable.
 
Is there an internal pot somewhere that adjusts the level of the
microphone?  I have haard others with the 706 MKII using a stock mic and
they sound just fine.
 
Thanks for the help.
