10/11 meters / 11m DX Activity 4 DEC 2024

« on: December 04, 2024, 1406 UTC »

The upper side of 11m is quite active this morning. Multiple NA and European ops 27.555usb; right along with QRMers. Noted a portable op in Wisconsin on frequency, too. Thought I might have heard even a possible Middle East prefix, but definitely a huge YMMV there.

Airspy HF+D and 30' inverted delta loop with preamp. AFAIK, the loop is still approximately NNE/SSW in plane, so a broadside vaguely towards Europe.
