Commander Bandspread "tolerance"


 

This morning 3XY1T was calling CQ (split) just a hundred (if that) Hz
or so below 24,890 for a while. Tuning to him - even when split with
the TX VFO in the band - caused Commander to blank the bandspread and
switch to the "out of band" color. Short of editing the Sub-Band
definition files to "extend" each band by 1 KHz, is there a way to:
(1) provide some tolerance on the band edges or (2) trigger the
blanking/out of band action based on the transmit frequency?

If not, could there be?

I would guess that, technically, if the other fellow is out of band, then it's not a valid contact for DXCC.? I have run into that with a DX station recently, when I zero-beat him I concluded he was 30 Hz low.? Now, my rig might not be exactly on frequency... my justification for counting the QSO was that at least PART of his signal was within the band.

Laugh if you will...

Just worked him 17M at 10.068126 (126 Hz inside the band) all the spots I see for him in 12M show he is on or slightly above the band edge. 3 of the 12M spots were from reverse beacon stations that show him at 24.891. He is working close to the band edges and guess he could have slipped a bit at one point but I would be pretty careful that close to the edge.

Please forgive fat fingers that was supposed to say 18.068126 :-(

How did that impede your ability to work 3XY1T? Presumably you weren't interested in other 17m spots at that moment.

When working split, a considerate operator would try to be aware of
other DX "up the band", and try to avoid transmitting over it. It
might also be helpful when determining the spread of the target DX's
pile (if there are multiple "clumps", some of them may be calling
other DX).

+++ Right, but the considerate operator should do that by tuning up the band and listening, not by relying on cluster spots.

+++ Callers in a pileup generally aren't spotted.

+++ That said, I don't see or recall any reason to hide spots when you tune out of the current band. I've sent you and Joe W4TV a version of Commander that no longer does that; please let me know how it goes...

I may not be able to hear the other DX, though - depending on prop to
my location. Just because I don't hear it doesn't mean I wouldn't be
QRMing by transmitting on/near it.


It might also be helpful when determining the spread of the target DX's pile (if there are multiple "clumps", some of them may be calling other DX).

No, but if you hear a clump of callers, and there's some juicy DX
spotted below it, you can piece the picture together.

It's all about being aware of your surroundings - like using your
mirrors and your ears when driving.

It "works as advertised" (from a quick check). I'll be on the lookout
for anomalies...

Works as advertised. I appreciate not losing spots in the band map
when tuning the RX a short way out of the band. I have other soft-
ware and hardware that inhibit PTT when the transmitter is out of
band.

Thanks for the testing, Joe!
