As an example of how you can set up markers, span and center frequency.

I was wondering if anyone has come up with a macro that will (reliably) move
the P3 to a frequency (K3 VFO A) and center that frequency on the display?
I have a P3 w/ SVGA. I am using the latest firmware(MCU 1.60; SVGA 1.34;
FPGA 1.04). I am testing macros using the latest P3 utility(1.16.3.15)
Command Tester. (FYI - I live in Fixed Tune Mode.)
Consider the following scenario: Three macros that each move (FA) to 2.5
MHz, 5.0 MHz, and 10.0 MHz respectively and then center the display (#CTF or
#CTF 0 or #RCF 0 or #FXT0;#FXT1; or even just an FA again).
(And yes, I do have more useful needs for this, but this seems like a simple
example.)
Execute them one after the other.
After each macro, I am always left with the Frequency Cursor at the left
edge of the P3 display which is the desired frequency and now defined as the
P3 "Center Frequency" as displayed in the middle of the top edge of the
display (this is also the frequency indicated at the left of the top edge of
the display, the "Lower Frequency Limit").
If I execute the same macro a second time I am centered on the display just
fine. The breakdown seems to occur if I am commanding a new frequency which
is not within some range of the current P3 display. IE. - Going from 2.5 MHz
to 5.0 MHz fails but from 2.706 MHz to 2.5 MHz works.
(Bulletin! - Extensive (!) testing has shown that the 2.5 MHz macro will
work properly if the starting frequency is in the range of 100KHz - 2.999
MHz; the 5.0 MHz macro will work properly in the starting frequency range of
4.800 - 5.999 MHz; and the 10 MHz macro will work properly in the starting
frequency range of 9.000 - 22.999 MHz.)
I think that (from K3 relay noises) those boundaries coincide with some band
filter switching. I have no idea what that means.
I have tried every command combination that I can think of to no avail.
Breaking the macro into separate components works fine.
But it would be nice to accomplish this without having to execute two
separate macros.
Of course the internal programming of the P3 is a black box to me, but the
behavior suggests that it may be a timing issue for the macro execution. It
is as if, after executing the FA command, the centering commands are still
seeing the previous frequency and falling back on the default behavior of
parking at the left edge of the display whenever it thinks that it is being
commanded out of the range of the current P3 display. Even though it isn't.
But that may just be a fantasy I have created in my own mind!
I am happy to entertain any suggestions. Keep in mind that the manual would
make you think that several options should work just fine but the execution
isn't so copacetic. You might want to try things out with the Utility's
Command Tester. Maybe my understanding of what should be possible needs
realignment. ;)
Or perhaps I should just resign myself to the reality that it doesn't work
the way I want it to and move on! :)
Thanks for any hints or tips.
