P3

I’m new on the reflector as of today. I searched for this and didn’t see anything that addresses my thought and I hope I’m not repeating something that has already been covered somewhere. If so, please let me know.

To me it would be useful if the following capability were available to me:

When I move a marker with the P3 knob and then tap it to tune the K3 frequency to my selection, I almost never hit the exact carrier frequency in SSB. I then have to move my hand over to the K3 VFO for fine tuning. It’s not a big deal but over and over in a contest this might become time consuming.

If, after tapping the select knob on the P3 it would be useful to me if, for a few seconds, the knob were to become a direct K3 fine frequency tune control. I wouldn’t have to switch back and forth between the P3 & K3 all the time. If the knob isn’t turned for a short time, say 5-seconds, it would revert to its normal operation of moving the marker only.

Others’ thoughts on this would be welcome.

Thanks,
Bob, W7KWS

Re: P3

Not a bad idea -- the notion would be to allow "fine tuning" of the marker position (and actual receive frequency) after a press. It should also still be possible for a press/hold to get you back to the original frequency.

I find the P3 knob smallish and unnatural to tune. I find the P3 knob tap
not to my liking. My hands are busy enough during a contest, that I don't
like to move one to the P3.

Here's what I do.

Tune the B marker using VFO B knob. Select the frequency by tapping K3 A/B.
Fine tune with VFO A knob.

[P3] Rounded-off start frequencies

In reply to this post by Grant Youngman

In version 1.09, the algorithm for rounding off the start frequency
should be unchanged from the last production release (1.05).

The start frequency is rounded off only if the K3 VFO A is jumped to
some frequency well outside the current display span. If you just tune
VFO A past the edge of the display, then the center frequency changes
based on MENU:FixMode, but the start frequency is not automatically
rounded off. That was done on the theory that the operator may have set
a certain display range for a reason and would want it to be the same
when he tunes back again.

So, for example, if you select Tracking mode, the center frequency is
set to the VFO A frequency. You can change the center frequency (and
thus the start/stop frequencies) to whatever you want by tuning the K3
or by using the P3 CENTER control. If you then switch to Fixed-Tune
mode, the center frequency and start/stop frequencies stay the same.

The problem with always rounding off the start frequency is that it
might prevent the operator from setting it where he wants it (a contest
or DX segment, for example). So it's a feature, not a bug. :=)

It is always possible for an operator to set the "band edge" where he
wants it with the "static" or "slide" settings for Fixed Mode Auto
Adjust. The inability to round the start frequency in the half-span
and full span modes makes the fixed modes much less useful ... and
rather defeats the purpose of full/half span, in my opinion.

I chose half-span adjust with spans of 5, 10, 20, 25, 50, 100 or 200
KHz so I can easily "read" the frequency of interesting signals from
the graticule. If it is necessary for the user to tune to a specific
frequency. then cycle from fixed to tracking and back to fixed just
to set the start frequency to a "round" number, the fixed tune modes
might as well be eliminated since the "odd" frequency scale destroys
most of the utility of the fixed full and half span modes.
