Dear Valerio, LF Group,
I made 3 x 25 minute recordings of IK5ZPV's Wolf beacon, starting
at 1900, 2000 and 2100 last night; all decoded OK. Indicated
frequency was between about +0.1Hz and +0.4Hz. The first
recording took some time to start decoding, but the second and
third decoded within the first 2 frames of data. So still plenty of
margin. No signal was visible on the spectrogram display, although
there were some funny "Luxemboug Effect" noises from time to
Cheers, Jim Moritz

Frequency generator is a DDS driven by a 10 MHz crystall oscillator
without any frequency stabilization.
Thanks to the other for the reports.
