P3 Span limits in Fixed Tune mode

[k6dgw]

I generally operate CW at 20KHz spans, with the bottom edge of the
screen at an even 20 KHz boundary.  Seems to work well, occasionally
I'll find it different, not sure why.

In SS CW, I noticed that my lower span boundary was often 5 KHz up from
the normal value ... such as 14025.  It seemed to happen more when I was
using the N1MM Band Map and clicking on spots, which sends frequency
change commands to the K3.

This is not a big deal, I just sort of like the bottom of the band to be
at the bottom of the P3 span, but I can't find any other reason to
complain except that I'm a retired engineer ... you know how we are,
just ask my wife.

This P3 effect doesn't seem to happen any other time, but it was pretty
regular when the laptop was sending frequency commands to the K3.

Just curious, maybe someone else has noticed this ... or maybe not and
my mind made it all up.

73,

Hi Fred,

When the K3 VFO A frequency gets outside of the P3 displayed span, the
P3 center frequency may change to keep VFO A on-screen, depending on the
setting of the FixMode menu setting.  If you set FixMode to "Static"
then the displayed range should not change no matter what the K3 is doing.
