I can't imagine this reliably working well. If noise gets onto long, overhead power lines, it will radiate for a long distance. The noise radiated by lines closer to the shack than the actual source

As a utility RFI Investigator, I am always polite when speaking with complainants. However, I typically ignore any specific pole references they provide. In my experience this information is 99% wron

I had a post-military (comms and avionics) second career of ~30 years in EMC engineering, and found a small untuned loop works well on some hand held radios, not so well on others. Loops like the one

Not surprising -- the TH-F6A has pretty poor sensitivity below VHF. 73, Jim K9YC _______________________________________________ RFI mailing list RFI@contesting.com http://lists.contesting.com/mailma

Tecsun 660 is a great hand held portable radio for listening around on the 160 meter ham band. Does good AM and SSB. Not unusual to use a few feet of wire antenna to improve pickup with out increasin

Has anyone modified their Tecsun so you can use a plug-in loop antenna for 160M instead of the collapsible vertical? The internal antenna is not connected above the AM band. 73, N2TK, Tony Tecsun 660

No need for a mod -- there's a 1/8-in jack near the top of the left side. I don't know how low in frequency it works, but it's good at VHF. 73, Jim K9YC ______________________________________________

It's been years since I tested mine before it died but as I recall, it was quite sensitive in the HF range if you use a 50 ohm signal generator. A short whip is something like 10,000 ohms of impedanc

Good point, Courtland. Most little HF receives like the Degen/Kaito 1103 series utilize "active antenna" technology (using a JFET as a buffer amp) in conjunction with the whipantenna, and the Degen 1
