[Elecraft] K3 Setup and CM500 Headset Questions

[Igor Kosvin]

The CM500 has electret condenser microphone. It require bias. If you want to
use front panel you have to use little battery box that came with the
headset. Just install the batteries and connect the battery box in series
with the microphone cable. If you decide to use rear panel, you do not need
the battery box, just need to use menu setting for rear panel mic with bias.

Subject: [Elecraft] K3 Setup and CM500 Headset Questions

Hello everyone. I have a couple questions for you. I have browsed the
archives and I was not seeing anything that was helping.

This is a new K3 to me, the guy before was primarily a CW operator. He did
not even own a mic. So I decided to buy the Yamaha CM500 headset and was
trying to get it all setup this evening. Below is some of the things I have
tried. In short, I am looking for the settings you have found to work.

I am following the Fred Cady guide that I bought online. I am in the setting
up
SSB section.

I was in test mode. When I was not in test mode I could get the TX light to
come on via the PTT foot pedal, the XMIT button and never VOX. I never
heard myself in test mode even when messing around with the Monitor,
Compression, MicGain, VOX Gain and the VOX Interrupt, Mic+Line (off). I am
using the Front Panel, Low, Heil adapter. I tried the
headphones/mic on the computer, they sound great and the mic picks up very
well.

So, with VOX not going off at all. I suspect the mic connection is not
getting to the radio. My headphones came with 1/8" to 1/4" adapters. 1
stereo and 1 mono.

the mic on the headset is 1/8" and goes directly into the adapter along
with the 1/4" PTT pedal. I then have the stereo 1/8" to 1/4" for the audio
and that is plugged into the front. I also wasn't sure what to connect
it to on the back since there are warning messages near the stereo
connectors on the back. I was afraid
to mess with anything there.

Is it a bias issue? A connector issue? Software setting?

Thanks in advance for any assistance.
