Hello, new subscriber here. Thanks for setting up this list.
I'm trying to connect a Heil Pro Set Elite headphones and mic to a KX-3.
I'm confused by what I'm thinking is conflicting advice. The Heil mic
has a dynamic element, while the KX-3 is normally used with the MH-3 mic
with an electret element requiring bias voltage. I'm using the
HLN-AD-1-KX3 adapter from DXEngineering to connect them.
With regard to RTFM: I found the section on page 38 regarding MIC BIAS
and MIC BTN. I understand that I should set MIC BIAS to OFF for the Heil
headset. I think I should also set the MIC BTN to PTT, because I have a
foot pedal connected to the adapter.
However, I'm confused by the flyer at
https://ftp.elecraft.com/KX3/Manuals%20Downloads/E740174%20Proset%20for%20the%20KX3%20Rev%20A.pdf
which seems to indicate that MIC BIAS should be ON, and MIC BTN OFF to
disable all PTT switches. This indicates that the transmitter should be
triggered only by VOX or the XMIT front panel switch.
And, also confusing, I found the email thread at
http://elecraft.365791.n2.nabble.com/Microphone-Setup-tp7609912.html
which is for the K3. I wasn't sure if this advice for the K3 could also
be applied to the KX-3. In particular, the note at
http://elecraft.365791.n2.nabble.com/Microphone-Setup-tp7609912p7609921.html
uses a MIC SEL menu option, which doesn't seem to be available on the
KX-3. It does have lots of detailed information about settings for TX EQ
which I'd like to use if applicable.
I only have the opportunity to use the KX-3 at our club shack, about
once a week, so I can't just turn to it and experiment. I'm also worried
about causing permanent damage to either the radio or the headset by
just trying things out.
Any advice to clear up my confusion? Thanks for any help and guidance.
