Re: [Elecraft] CM500 headset on K3S and KX3?

Frank, Although the K3S rear jack is marked mono, it is actually a stereo jack, but the ring connects to nothing - so no harm. On the KX3, look in the manual for the MIC jack connections. It should tell you why you need to be aware of the situation that the CM500 plug can present. Walt Und

Re: [Elecraft] CM500 headset on K3S and KX3?

Frank; The rear-panel mic input on the K3 and K3S is actually a stereo jack. The ring connector is not connected. Plug the CM-500’s mic plug in (as I do), and it will work just fine! Remember to enable bias on the rear panel Mic as W3FPR noted. The CM-500 is an excellent headset for use with th

Re: [Elecraft] KX3 digital ops, MacOS

I use RUMlogNG (free from the app store) for general and contest logging. It will also use CAT commands to transmit and receive in it's contest mode. For general digital use, fldigi and wsjt-x are probably the best at the moment. There used to be cocoaModem, which was generally better than fl

I adapters needed. CM500 plugs right into the rear Mic and Phone jack on K3(s). Also the KX3, just turn OFF Bias and Buttons. PTT is available on rear PTT RCA jack on K3(s) and Tip and Shield on KX3 Accessary jack ( a 3/32 TRS Jack next to the I/Q Jack). Use switch of your choice; an o

Re: [Elecraft] Upper limits of KPA500?

Why not let the computer in the amp do its job? And besides, the fans run after the amp is turned OFF. This discharges the caps and starts the orderly “cool down” cycle. You may be a brilliant engineer, but no need to re-engineer a system that works pretty well. Sent from my iPhone ...nr4c.

For the KX3, an off-the-shelf stereo-to-mono splitter will separate the mic and PTT lines. It also separates the mic bias (clean) from the logic signal (not so clean). Details here: https://observer.wunderwood.org/2015/08/16/yamaha-cm500-headset-with-ptt-on-elecraft-kx3/ For transmit audio setu
