P3 question

I run my P3 in fixed-tune mode [span edges stay fixed, cursor moves as I
tune]. Every now and then, the span edges will jump in frequency. For
example, with span=20KHz and edges=21.020/21.040, at some point the
edges will be 21.025/21.045 I've never caught it in the act and I can't
make it happen, it just does it when I'm not watching. Anyone know
what's going on?

For the record, Elecraft cables: KUSB [laptop]-->P3-->K3.

Re: P3 question

check the P3 setting under
MENU/Fix Mode
Fix-tune auto-adjust mode
select which you want: Half Span / Slide / Static

Re: P3 question

It's set to Full-Span, and every time I tune off the edge, I get the
next full span, up or down. When this anomaly occurs, it is usually [as
in almost always] a 5KHz shift. If the left edge was at 1.040, it will
become 14.045 and the right edge will become 14.065 I've never seen it
actually do it, I just notice that it has occurred. It's no big deal,
I'm just curious what is going on.

Re: P3 question

I have mine set to half span
that way I don't loose everything I'm seeing I just get another 1/2
screen worth of the spans width added in the direction I am tuning.
I generally run either 10kc or 200kc spans.

Hi Fred,

While I don't have an answer to your question I would like to offer an unrelated "Fixed Tune Mode" tip. Frequently I want to get the station of interest into the center of the screen but remain in Fixed Tune Mode. I think there are other ways to accomplish this but the one I use is to quickly toggle from Fixed Tune to Tracking and back to Fixed Tune. I do this by setting the menu option of FixTrack as a top row function key. A quick double tap of the function key moves the station to the center of the screen.

<CENTER><CENTER> will center the display on the VFO A frequency in
Fixed Tune mode.
