[Elecraft] KX2 RTTY Help

Trying to get RTTY running on my KX2, but no luck, so far. The KX2 is setup for WSJTx and works properly (TX and RX) with both straight audio cables to the computer and through a SignaLink USB. My conclusion from this is that the audio connections and audio gains must be set relatively close.

I think we’re talking about two different pairs of screws: - The thumb screws in the KXPD2 are identical in length (with blunt tip). I’m sure that’s not Mike’s issue. - The other screws are the 2-56 pan-heads that hold the paddle together. These come in from the back side. It’s possible

Mike, It sounds like your KXPD2 may have a 3D printed housing that was prepared incorrectly (sanded too much on the back side). This could leave the screw heads slightly exposed. You can contact support to obtain a replacement. As a temporary workaround, place a bit of adhesive label material

John, It has been my perception that the changing resistance of the 1/8” TRRS Mic plug, as it rotates slightly when holding the Mic, is the source of the frequency instability. Turning off the Up/Dwn function, as you have discovered, is the cure. Very 73 - Mike - K9JRI > On Jun 14,

Well, I just checked and switching MIC BTN to PTT has resolved the issue. Thanks! Looking more carefully, the frequency down-jumping glitch occurs on my KX3 about every 10-20 actuations of the PTT switch - the timing seems random, but is often enough to be irritating. And it stops with the

If switching from “MIC BTN” to “PTT” fixes the problem, then it must be related to the way firmware reads the mic buttons. it could be that we need to tweak the A-to-D thresholds a bit. Anyone who has this issue could use the “PTT” setting as a work-around, assuming they don’t require the
