Let me add my 2 cents. I heard so much crap audio this weekend, that all I can recommend is that you use a Mic element purpose designed for the job of SSB QRP communications. I have recordings of good and bad examples that I will assemble into something useful at some point.
I heard guys with big wide signals that I could not understand who were running lots of power. I also worked many QRP guys with amazing audio that was correctly shaped for SSB. Don't kid yourself, that $2 computer mic, while it sounds ok locally doesn't cut it when you need your signal to be understood. This is not about FM full range audio. This is about being heard and understood. Bob Heil spent lots of time designing the right mic element for SSB communications. He did this with input from Bell Labs. Leo Laporte did a great interview with Bob where he describes why he did it. Since you asked, my choice every time is the HC5 with the right cables. Keep a close eye on your ALC settings too. Your KX3 will work just fine and you will be heard. 73, Mike va3mw On Sun, Oct 26, 2014 at 9:08 PM, Don Wilhelm <[email protected]> wrote: > Tim, > > You can use many headsets and microphones with the KX3 - *IF* you are > willing to build an adapter. > I have my homebrew adapter for the CM500 headset that works just fine, but > if you are not able/willing to build your own adapter, order the Elecraft > MH3 microphone - it works just fine. > > Computer type microphones and headsets can be made to work, but because > the tip and ring are connected together, there is some special > considerations to be had when choosing the bias - they work OK with bias > turned off, but then will be using the source for digital voltage in the K3 > to bias the microphone which can cause noise in the signal.
