Transatlantic reception on 500kHz

This evening, early, the transatlantic WSPR stations are coming through well into Europe. So far I've only seen WE2XGR/6, running 100W, appear on the screen on 511.5kHz, which is above the UK allocation. This is a new transatlantic station for me. The signal is varying in QSB with around 8 minutes between peaks of signal.

UPDATE: I eventually moved off 511.5kHz at 8am this morning and WE2XGR/6 had been coming in all night until then. At best it reached -14dB S/N with me on one occasion but usually it was around -20 to -25dB S/N level. Also copied was WE2XGR/2 who was running 50W. He was audible until 0638am

500kHz WOLF - transatlantic?

This evening, I'm going to have a go at listening out for one of the USA stations on 500kHz who will be testing with WOLF (very weak signal mode) overnight. Not sure what my chances will be but it's worth a go. WE2XGR/2 (Burlington CT, USA) will be on 508.5kHz for about 4 hours from 2230z.

UPDATE: Sadly no copy. I left the rig and software running all night but clearly my system did not have enough sensitivity.
