[Elecraft] MH2 Mic issue

[Stephen Rector]

Hi All:

I'm new to this list. As of last week, my K2 s/n 6770 is up and  
running - I'm quite happy with it. Even though I have a stealth sloper  
to a pine tree (HOA restriction), the receiver has impressed me, and  
the QRP gets out (next weekend's board is the 100W PA). This weekend I  
got three of the accessory boards installed pretty much without a  
hitch, except for a problem with the MH2 hand mic.

The KSSB2 board seems fully functional and I get good reports on  
transmit audio when I use a Heil HM-10 with the K2. But when I plug in  
the new MH2 hand mic, the T/R keys but with zero audio: no ALC  
indication and no RF. Is there a measurement I can make on the MH2  
before sending it back? (I wired in the 5.6K resistor from pins 2-6  
per the instructions)
