KX2 lowers frequency with PTT

Has anyone else with the KX2 noticed it will lower frequency on occasion when you press PTT on the external mic? I’m definitely not moving the vfo or mic up/down buttons. For example say I’m on 7.195.00 it will drop to 7.194.99, it never goes up only down. It’s rather annoying.

Re: KX2 lowers frequency with PTT

Hi Adrian,

My KX3 has demonstrated this “feature” from the very beginning. As you
describe, it always jumps down exactly 0.01 and only ever as I hit PTT on
the hand mic. I’m happy to know I’m not alone!

73,

I’ll try to duplicate this (never seen it myself).

Is XIT turned off?

Re: KX2 lowers frequency with PTT

I used to have this issue (KX3) - I don't recall if it went up or down (I
think down). I assumed that I was inadvertently pushing the microphone
buttons & subsequently switched the "MIC BTN" menu item to "PTT". I have
not had the problem occur again.

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 UP/DN functions.

Thanks,

Re: KX2 lowers frequency with PTT

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 change in the
MIC BTN menu item to PTT.

Re: KX2 lowers frequency with PTT

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.

Dear Friends,
I had just the same issue with my KX3 and was fixed switching MIC BTN menu to PTT.
Thanks for this great information!
All the best to all,
