K3S Microphone

Thanks for all the responses. I find them very interesting. The only thing that I'm missing is comments on the Elecraft MH2 Handset. I noticed that the CM500 has two stereo plugs and the mike inputs are mono. I have a Yaesu desk mike but can't figure out the menu settings to use it's PTT switching. In the meantime, I'm having fun with the Heil K2 headset that I bought for use with my KX3. Having great fun with the new K3S! Jim KC0TRK

Jim,

A Yaesu microphone will not work with the K3/K3S unless you construct an
adapter to change the microphone pinout.  There are no menu settings to
accomplish that feat, you must build an adapter to route the AF and PTT
and their Return paths to the appropriate pins on the K3/K3S microphone
jack.

The CM500 has a stereo mic plug, but the tip and ring are connected
together.  That is no "never mind" for the K3, but for the KX3, it does
cause a problem.  Without building an adapter, you can turn off bias and
turn MIC BTN off, and it will work.  The bias is supplied from the
residual voltage of the digital voltage designed for the MIC BTN.  If
you find that digital voltage produces digital noise in your signal, the
only cure is to build an adapter to isolate the ring from that digital
voltage and if you do that, you will have to turn BIAS on for the CM500
to operate.

Rewire the mic plug - just remember it is - from then on - only to be
used on your K3. It is a 10 minute job - very simple.

Or buy a microphone adaptor on EBay.  You can find any type you need there.

I have a MH2 as well as a CM500. The MH2 works very well. I use
it when my wife and I check into repeater nets so we both can
pick it up and transmit. I use it as a push-to-talk switch when
I'm using the CM500. (Some day i'll do the foot switch project.
Too much time operating, too little building.)

I'm not a frequent phone operator but thought I should at least have a mic so I bought an MH2 when I ordered my K3 years ago. I used it a few times but decided I didn't want to use a hand mic at the operating desk and put it away in a drawer. (I take it when I deploy to Field Day since some ops like to use it.)  

Instead I bought a very light weight $20 Best Buy computer/iPhone headset and use VOX all the time. The K3's TX EQ fixed most of its shortcomings. I get good audio reports.

I did respond but perhaps not clearly enough. Although I like my Koss SB45 headset, I use my MH2 daily and never had a complaint. TX EQ on the fph with bias is set up for the mh2  and numerous compliments received.
The rph with bias is set up for the SB45 including the TX EQ.
Config: Fph with bias saved to PF1 and I can easily switch between the two with no other adjustments are needed.
Simple, well for me at least.

Gary
