[Elecraft] Heil BM-10 Headset

[Dave Cox]

I just purchased a used Heil BM-10 headset, and I'm trying to determine how
to connect it to my KX3. Neither Heil nor Elecraft have been much help. The
headphone component works fine, but the mic has been a bit of a challenge.
Elecraft said that no adapter is needed and that the BM-10 should work just
fine with the 1/8" mic mono plug plugged directly into the mic jack on the
KX3, but it doesn't work, even after I set the MICBIAS and MICBTN both to
"OFF." The BM-10 has an HC-5 element. Is a Heil adapter required? If so,
which one? Any ideas on how best to connect the mic will be greatly
appreciated. --Dave, NB5N
