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.

WOLF weak signal mode success
After a frustrating evening of not decoding a WOLF signal, I was told how to calibrate my PC's sound card. Then I retried decoding M0BMU's signal and met with immediate success:2009-09-10 21:15:29 >WOLF10 -r 8100.257 -f 1000 -t 1 -w 0.0000
t: 24 f:-0.339 a:-1.5 dp: 85.6 ci: 7 cj:272 M0BMU IO91VR 2W -
It seems this mode is more critical than WSPR but offers the prospect of decoding even weaker signals on the LF bands. The calibration is easily done using the 198kHz Radio 2 signal and takes only a couple of seconds.
