Starting at 1730 UTC. WebSDR (technically, a KiwiSDR located grid IO80PW). Clearly some propagation from Eastern Europe going on. The 26 MHz region was interesting to look at on the waterfall. Very organized use of 10 kHz steps and USB mode. Once you get closer to the "mid band" or "CEPT" European band (26.965 to 27.405 MHz), things get a little crazier. Basically, throw out the 10 kHz channel steps. They're now 5 kHz steps. Oh, and there's Russians EVERYWHERE. They're even having a casual QSO in USB mode on 27190 kHz, right next to the very busy 27180 and 27185 frequencies (Polish "zeros" frequency CB Channel 19 and EU/CEPT/EC channel 19) No matter. The area around 27.5 MHz is also nice and organized. 5 kHz steps, almost all USB mode, and stations that called CQ on 27555 USB then QSY to another nearby frequency.
FM seems to be the main mode of choice, with some AM and USB thrown in for good measure. The use of SSB appears to almost entirely be outside the legal frequency bands. The UK FM 27/81 CB band 27.60125 to 27.99125 MHz (or 27601.25 to 27991.25 kHz) band was also busy, but I only logged a couple signals on the actual channels (of course, Russians using whatever frequency they want were also found in the 27.6 to 28 MHz area).
Lots of pagers and other data transmitters logged, and of course, the Italians on 27075 AM, 27465 AM and others.
