Normally I get all sorts of buzzing, rasping, crackiling noise over the
whole RF spectrum. I have identified some of them. Some of the fluorescent light bulbs put out an awful racket. The can be sniffed out with a portable radio and replaced with quiet ones. All light dimmers are replaced with off/on switches. The Neptune washing machine has a dc motor so no washing while I am trying to listen. But in spite of these efforts there was still lots of RF noise at about a S5 level. One night we had an ice storm that took out the power line. The RF silence was deafening. I could hear dx station clearly for the first time. Brother Stair, Alex Jones, EWTN, they were all in there ( just kidding) But there were still RF noises that could only be on the phone line. Unmodulated carriers, beedeleebeedelee sounds. all up and down the dial, but not wideband like the electrical racket. Then the phone lines went out when another tree went down. At last! no RF racket. I started logging dx for the first time in years. Then the power came back on and it all went away. So there are three sources of RF racket: (1) Things inside your house (and neighbour's) (2) the power lines (3) the phone lines The only fix that worked was to put up a sloper at the back of the lot and run 150ft of co-ax to the house. There is still a little hash, about S2 but it is the best I can do. |
