Eureka!! I found the QRM-source!

…and beleive it or not, it was the computer making noise, while radiating in such a way that it affected the MFJ-1026 ability to phase my loops correctly! I suddenly got the idea that I should try to connect my ICF-2001D to the phasing unit, and remove the SDR-IQ, computer and USB-hubs and voilá! Noise gone! Why in H*ll didn´t I think of doing that before? Tunnel-sight??

Tomorrow I will try to re-arrange the SDR-IQ setup in such a way that the computer and accessories doesn´t affect the phasing unit.

Right now listening with the ICF-2001D connected and it’s a true pleasure!


About Hans

Male. 50 years young. DX:er since 1980. In September 2011 I moved up to Vardø on Vardøya Island (EU-141) to start working as manager for the Coast Radio station in Vardø. I feel very lucky to have this opportunity to work with the thing that I think is the most interesting in the whole world - Radio! My main interest is, yeah - you guessed right: Radio. I'm a ham radio operator, holding the callsign LA2MOA. My main radio interests is low power operation and low band DXing on the amateur bands, but also mediumwave and tropical band DX-listening. I'm also interested in angling, fly-fishing and fly-tying. The area around Vardø offers some great opportunities to do all of this. And, since I'm of swedish origin, I'm also madly interested in ice-hockey and since 35 years I'm a hardcore supporter of Rögle BK in Ängelholm - one of the few really true hockey clubs left in Sweden.
