Subject: [dxlab] 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.

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.

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

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).

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

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.

+++ 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...

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