Took a look at the other side of the big pond via Twente SDR at ~1200z. Various 11m FM activity noted, including an op on 27205 outside of Moscow.
Switched over to an Antron 99 18' vertical mounted at ~20' with four ~8.5' radials. I still need to tune it down like 400-500KHz or so, but "whatever" for receiving purposes.
