Steve,
Re-check those instructions for the MH2. The resistor goes between pins
1 and 6. Pin 1 is the AF line, and pin 6 is the 5 volt line. You must
pipe voltage to the AF line on the mike (through the resistor) to make
it produce audio.
BTW, pin 2 is the PTT pin.

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)
