Noise and 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 |

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?

External antenna with coax feed. My radios are within three fee of the
computer with no problem. "Dealmeister" wrote in message m... Two questions: 1. I like to surf the web while Dxing; my computer creates a lot of noise.

Anythoughts on how I can cut down the noise? One cause of computer noise is that PC case manufacturers economize by using swithcing power supplies which have the RFI filtering components intentionally left out. Usually there is a place on the power supply circuit board for a power line choke and bypass capacitors. They leave the capacitors out and jumper the choke connections. I would try to find a better case with a quiet power supply and good bonding of the metal to metal surfaces of the case. These usually cost more. In my case, when I installed a choke and capacitors inside the PS, the RFI noise dropped about 30 db on the broadcast band and about 7 S-units on 40 meters. KO6NO |
