Uggh, I've been pulling my hair out over crackling I'm hearing on the HF/SW bands for the last month or so.
It'd gotten to the pointed where most of HF was unlistenable. I'd put an AM Broadcast filter in line and that didn't seem to negate anything even in the slightest. I switched out a few cables and tuner, didn't help. So I pulled out the cards one by one in my JRC NRD535D, inspecting them for any burnt odor or appearance. Nope, so I reseated them.. and viola, the problem seemed to go away. Well, it started coming back again. So, I put another radio in it's place and it still happened. So, I did the only thing left that I hadn't done yet and unplugged my Wellbrook ALA100LN giant magnetic loop.. and boom, the noise is gone. Somewhere, something has gone faulty in the Wellbrook. I'm getting some Deoxit in the mail and will spray down/clean off a few things and see if it's just a rusty connection somewhere.. it sounds kinda "rusty" or dirty somewhere if you know what I mean? The only constant between all of this is the Wellbrook, when I got rid of that from the equation, the noise went away. I don't think it's heat because the two Wellbrook boxes are pretty well shielded These things have been outside in the rain, so I suspect water has gotten to something that shouldn't I'm also going to replace the cabling between the antenna and the radio gear and replace the actual antenna wire too. This has been driving me crazy because it's ruining my HF/SW reception. I can't think of anything else it could be besides the Wellbrook so now I just have to figure out EXACTLY what's wrong with the Welbrook., FYI, this is what I have: http://www.loop-antennas.com/North_American/ALA100LN-2 my antenna wire is 25 feet long by 10 feet tall and in the shape of a volleyball net magnetic loop antenna. _ Hard-Core-DX mailing list Hard-Core-DX@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/hard-core-dx http://www.hard-core-dx.com/ _______________________________________________ THE INFORMATION IN THIS ARTICLE IS FREE.
