Now that the temps are 11 degree F, I really hope the utility
has their power problems fixed. We had a scheduled 90 minute outage last night from 4:00PN to 5:30PM EST. At 4:55 I opened the main breakers to protect the heat pump and fridge from transients. In an effort to verify my idea that simple antennas are adequate for RF quiet locations I asked my wife to route a ~70' wire from a 15' tall fiber glass pole attached to a fence post into my radio room window. I have a piece of Lexan that is 2' high and just fits into to the storm window. It has a variety of holes from antenna experiments over the last 25 years. The entry point is about 4' off the ground and the wire sloped up to a ~18' fiber glass pole. I was listening as the power went down, and like I expected the S3 noise vanished. The wire antenna wasn't as good as the roof mounted active antenna but the difference was minimal. I was using the high Z (500 ohms) on one R2000 and the 50 ohm with the roof mounted active antenna on the other R2000. Both R2000's are fairly stock and after 45 minutes I swapped the antennas and receivers. If I lived in a unpowered deep woods cabin then I wouldn't bother with 'fancier' antennas. A 50 to 100 foot wire and a well casing would do just fine. Of course powering a receiver becomes an issue. It was interesting as they brought us back on line one section after another. I could hear the noise increase but even with power on the next street over, the random direct wire antenna worked great. When they brought up our street the noise level went backup to S3. I am stating to wonder how much noise is coming in on the utility ground conductor. Terry |
