This is the third of four nights that I've been totally unable to hear
the BBC with any degree of audibility. For the record, I'm trying to receive The World Today at 0300 UTC. 9525 always seems to have or develop some strange, loud buzz that totally wipes out the signal. It can be clear at 0230 and when I tune back at 0300 it's developed this very loud noise that I can't null. It's like the buzzing of a flourescent light. 5975 always has a high noise floor for some reason, but lately it's been so bad that the signal underneath is just mush. I've tried all FIVE modes on my Yaesu FRG-8800 (AM, LSB, USB, CW, FM) and none of them work. I've tried adjusting tone, volume, narrowband, AGC, noise blanker, no dice. The same noises exist on my Degen 1102, so it's not the radio or the antenna. I'm using about 50 feet of speaker wire on the Yaesu, and the supplied external longwire on the Degen. A couple nights ago I listened as 9525 started out clear at 0300 but as time went on it developed the loud buzz, which ramped up gradually until the signal was inaudible. Is anybody else hearing this, or having the same problems? ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

I think the inteference you are experiencing is caused by the propagation
conditions changing as the night goes on. |

it is operating on 5975, loud and clear now and earlier this evening
when i tuned in on EST. technically, i do not know why you cannot hear it unless someone near you is operating some type of electronics that is interfering. minerva running dogg wrote: This is the third of four nights that I've been totally unable to hear the BBC with any degree of audibility.

it quite possibly could be computers or some digital equipment somewhere. It sounds more like propogation or bad weather. I know when I lived at my last apartment I had LOTS of wire strung all over heck and gone and a good earth ground consisting of 8 feet of rebar pounded down until I had 3 feet left above ground and kept the contact as clean as possible. When a storm front was approaching I would really get that noise you are talking about and if it got bad enough I disconnected the antenna and pulled the power plug out.
There is so much being transmitted through the air that if we could see it it would be a thick fog. Not all equipment is properly maintained; in particularly power lines, especially high tension lines. Some of it is so bad that the power company has had to come out to some areas and physically clean the dirt and crud off those high tension lines because people were being driven to distraction by the noise S. If there are bad spots, the current arcs and you get intermittent bursts of noise. Street lights are also offenders - mercury vapor and sodium vapor may make a lot of light but not without making a lot of noise as well. And it doesn't seem to matter what time of year it is, there will always be those times when the noise wipes out just about everything. Then when you are about to throw the set in the pond, you discover a station you never heard before g. A little patience can go a long way.

5975 comes in loud and clear, in fact the signal is so good I can hear
it without extending the antenna on my DE1103. I wonder if you don't have some sort of local interference. Maybe a neighbor has a new electronic toy that is radiating all sorts of noise. running dogg wrote: This is the third of four nights that I've been totally unable to hear the BBC with any degree of audibility.

When a storm front was approaching I would really get that noise you are talking about and if it got bad enough I disconnected the antenna and pulled the power plug out. Actually, there HAS been a weak storm system parked off the California coast since Sunday. It hasn't had any lightning associated with it, but it has been sending wave after wave of rain into northern California. It's supposed to move through on Friday, maybe then reception will improve. Other than that, reception has been the best it's been in a month over this past week. By the way, I tuned back at 0330 and noticed that the noise on 9525 had quieted enough to make the signal audible when using USB.

It might have something to do with a light or lamp controlled with a dimer switch. It is typical that the noise gets worse at lower frequencies as electronic devices are allowed to generate more noise at lower frequencies. -- Telamon Ventura, California |
