141. Re: [CQ-Contest] CW Open and the RBN (score: 1)

I wonder if those whose calls were mis-decoded were not looking at spots. (Even though there is no unassisted category in the CWops Open.) Perhaps those who plan to operate unassisted in other contes

The results of one contest really don't tell you anything. Propagation is just too variable. One of the biggest factors in DX contests is how close the path goes to the magnetic pole. If you play aro

Actually, we need two new Q-signals: "Spread out, so you aren't all zero beat with each other" and "You're so far off my frequency you're right on top of the station calling CQ next door" 73, Scott K

I generally set the bandwidth to 400 Hz, and pitch to 500. If bad QRM captures the AGC, I'll reduce the bandwidth to 250. However, if AGC capture isn't the issue, I find that reducing the bandwidth r

When I'm running with the K3, and adjacent QRM starts to move in, I find that narrowing the passband is often very effective, sometime just going from 400 to 350 Hz. I expect this is the same with al

I don't know the exact propagation mechanism, but this path from far northern EU to the northern US is very often open. We may experience it more often here in the north-central US, because our geoma

That makes sense. The key is that the path must pass through the auroral zone, but there's no F2 at the eastern end, because it's dark, so the path doesn't extend far south of the auroral zone. 73, S

Worst case is probably calling CQ with no replies. For example, my typical CQ takes about 4 seconds, and I listen for 1.8-2.5, depending on the contest. It should be easy to calculate the duty cycle

It would seem that spotting S&P contacts would be beneficial to the unassisted operator. Let them all fight over the station you just worked. The downside, I suppose, is that if everyone does that, t

That's true, but only part of the story. On the HF bands, receiver noise is almost always negligible, so absolute signal strength doesn't matter much. If your random wire isn't matched, all bets are
