K3 600Hz shift when A/B pressed (cw/ssb)

If I have different modes (cw/ssb) in A and B VFOs, when I press A/B the frequency being passed to VFO A goes up 600Hz (cw) or down 600Hz (ssb) each time A/B is pressed. Anyone else see this? What am I doing wrong?

You have the auto shift feature turned on. This makes the radio QSY by
your pitch setting when you go to and from CW mode.

Re: K3 600Hz shift when A/B pressed (cw/ssb)

Hi Brett,
Thanks for the reply. My CW pitch setting is 700Hz not 600Hz so this
still seems wrong? Also I am not switching between modes on a single VFO,
I'm swapping VFOs (A/B). Why should auto shift kick in for this action?

The auto shift kicks in in a few places it shouldn't at the current
moment. Not sure why yours is changing by a value other than your pitch
setting.

Doug,

Are you using POWERSDR/IF? If you are, is the version xxx.34? That
version had a bug caused the very shift you are seeing. Furthermore it
happened whether the A/B change was initiated by either the K3 buttons
or the POWERSDR panel. Upgrade to version xxx.35 to fix it.

Re: K3 600Hz shift when A/B pressed (cw/ssb)

Hi Don,
Yes I was using POWERSDR/IF earlier today when I noticed the bug.
Believe it or not I upgraded to v1.19.3.5 earlier today without making the
connection. I tried the same A/B thing again (just now) with the K3 (with
and without POWERSDR/IF v1.19.3.5 running) and it doesn't happen now. Looks
like I was experiencing the POWERSDR/IF v1.19.3.4 bug. That would have
driven me mad wondering why the odd behaviour vanished.

Superb bit of sleuthing Don.

Note to self: kill all related communication applications when K3 exhibits
odd behaviour.

Thanks again

Doug GM0ELP
