Noise & UTE Dxing question
Two questions:
1. I like to surf the web while Dxing; my computer creates a lot of noise. Too DX and surf, obviously the radio and PC need to be in relatively close proximity. Anythoughts on how I can cut down the noise? 2. Can anyone recommend a good decoder? Years ago I used the AEA PK-232. These days I'd like to buy a decoder that covers as much of the used formats as possible. Key for me will be simplicity though. I don't want something with a manual or operation that's so technical it won't be fun. I want something that is as "plug and play" as possible. Any thoughts would be appreciated! Thanks |

Anythoughts on how I can cut down the noise? I solved the problem by using a Toshiba Laptop. Laptops by design can be well shielded and some like the Toshiba are. And laptops have an LCD screen eliminating the CRT noise problem, otherwise see Computer noise abatement at URL; http://ac6v.com/comprfi.htm 2. Can anyone recommend a good decoder?

There are many possible sources of RF leakage -- did you assemble this PC
yourself, or did you purchase it as a system? You can try the shotgun approach -- wrap the main unit and monitor in grounded aluminum foil and place ferrite cores on all of its cables -- mouse, keyboard, monitor, AC, etc. If this knocks down the RF, then remove each item one at a time to identify the culprit. Be careful; sometimes there is more than one culprit. Back in the early 90's, the only way I could use my Commodore Amiga for logging was to wrap the main unit in aluminum foil and fabricate cable shields from aluminum foil. As this was supposedly an FCC class B certified device! For what its worth, every Dell PC I've purchased over the subsequent years has been RF quiet, as have the Eizo (ex-Nanao) CRT and Plasma monitors I use with them. 73, Dave, AA6YQ "Caveat Lector" wrote in message news:bmH8b.127939$kP.52327@fed1read03...
