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
That's the key: Put lots of mass in the way of the sound. 73, Scott K9MA -- Scott K9MA k9ma@sdellington.us _______________________________________________ CQ-Contest mailing list CQ-Contest@contestin
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
The robot initially rejected my N1MM Cabrillo logs. It apparently wanted an extra space in the two lines flagged with errors. 73, Scott K9MA -- Scott K9MA k9ma@sdellington.us ________________________
I suspect that, at the time of the rule change, there were getting to be a lot of solid-state transceivers that put out 100 W. 73, Scott K9MA -- Scott K9MA k9ma@sdellington.us _______________________
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
Years ago, when I started using progressive bifocals, it was clear that they were not good for some activities, including using computers. I just asked my optometrist for 3 prescriptions: reading, co
My neighbor is installing an Enphase solar system, just 20 meters or so from my antennas. Has anyone had any experience with their RFI performance? 73, Scott K9MA -- Scott K9MA k9ma@sdellington.us __
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
My next door neighbors recently installed a solar system, with the panels no more than 60 feet (18 m) from my antennas. The primary antenna is a tribander at 70 feet, with a 40 meter rotatable dipole
Audicity can record directly to disk. Otherwise, the Zoom H2N works well. 73, Scott K9MA -- Scott Ellington -- via iPad _______________________________________________ CQ-Contest mailing list CQ-Cont

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
