Hi Don,
This is much more complex than I originally thought!
The BM-10 was purchased with adapters for an Omni 6 (4-pin) and a Yaesu
817 (RG-xx). The pads are black and it has the HC-5 element. The cord
coming from the boomset has a connector that takes either above adapter,
or, it can go directly into the K2 mic connector. The headset only had
BM-10 shown as its model number.
All this discussion may be why I only do about 20 SSB Q's/yr on HF! Now
in the VHF rover I do 1000+/yr, but we the Yaesu hand mics that came
with the rigs.
Thanks,
Mark K2QO

Mark,
Still not enough info - BM-10 is a Heil number, not an Elecraft number, and
there are 3 models of the BM-10 - one with the HC-4 element, one with the
HC-5 element and one with an electret element for Icom. Are the pads blue,
red, or black?
The above info is only for starters - these mics are sold by Heil for
specific rigs and vary in the wiring at the plug, so you must also know
which transceiver it was originally intended for.
If I had to guess, I would say that your BM-10 is wired for the Yaesu which
uses pin 6 for PTT, and when you connect it to the K2 and press the
footswitch, you are shorting the K2 +5 volts pin (6) to ground. Heil refers
to the Yaesu BM-10 as BM-10-Y, but I don't know whether that is simply
ordering info or if that number is imprinted on the mic.

Subject: RE: [Elecraft] MH-2 and Boomset Problem
Don,
the Elecraft mike is the HM2 hand mike and the Heil boom set is the
discontinued BM-10. It's a smaller version of the full size Pro Set. Is
this enough to answer teh question?

Quoting Don Wilhelm <[EMAIL PROTECTED]>:
Mark,
Just saying 'Heil boom set' is not sufficient information to tell me
which
mic you actually have.
Is it the Elecraft MD2? Is it the Heil ProSet (if so, which one of
these is
it)? If the mic was made for use with an Elecraft or an Icom, then
it
should have an electret element in it, but if it has the Heil HC4 or
HC5
elements, it is a dynamic mic element and does not need voltage
applied to
it.
Let us know what you really have and perhaps we can help.

This should be and easy one. I have a K2, SN543, loaded with all
updates
and firmware but no 100W. I've used the HM-2 with for a couple of
years for a couple dozen SSB contacts. When I plug my Heil boom set
in
and key it with the foot pedal, the rig shuts off.
Does the resistor on the back of the mic connector need to be
removed to
use the boom set? I actually just tried this yesterday. Never
noticed
that the Heil came with a compatible connector, no adapter needed.
