Terry, I could use your self-description by adding "used to" in the context of contests (I'm up to 297 confirmed and contest opportunities for the rest are slim to none).
Then I'd add: "lives on tiny urban/city lot surrounded by both horrible QRM and hills." My antennas were as you describe: a 2-el 5-band beam up a whopping 30 feet, and a wire running through and around trees like a demented pretzel at that same height. And you're right, while diversity thrives on differences, it doesn't thrive on THOSE differences. In my quest for DXCC on 40 and 80, I'd added a pair of DXE active receive verticals and noise canceller in a failed attempt to phase my way through the s5-s6 noise wall - there were far too many noise sources for cancellation to be effective. So I was left with a receive antenna that didn't work all that well in noise-hell, either. Then, after letting it sit mostly unused for 6 months, I tried diversity reception. Wow. When you're working down near the noise, QSB can kill many a QSO. But even with my minimal antennas, the way signals "float" as the RF rotates through polarizations is remarkable to hear: a signal that would otherwise be lost often comes up in one ear just as it drops in the other... I recently worked VK6LW when he was unreadable on either the long-wire or the receive ant, but was readable with diversity turned on. It sometimes seems like the difference between mono and stereo music. Anyway, diversity reception was unquestionably the key to 80M DXCC from this QTH. Point is: if my K3 hadn't already had that second receiver, it's unlikely I would have added one just to try. So if you can swing the cash - like a good scout: "be prepared." 73 Chris NW6V Terry N7TB said: > > From: <[email protected]> > > 1. I am predominantly a CW operator > 2.
