No comments from you lately so I will reiterate, I am sending you WOLF every
night from 01 utc to 02 utc...........137.7894 is the TX freq
Larry
VA3LK
Two issues arise here.

Firstly, now we have daylight saving time 01 to 02 UTC is 2-3AM which is not a comfortable time. Does anyone know of a way to make a WAV file on a timer? I could record overnight but I suspect the file would be enormous.
Secondly - and this will cause some discussion (smoke!) - there is
considerable wideband noise at the top of the band very late at night. It is
usually attributed to the Luxemburg Effect. In the past it has caused little
problem as (1) we have used only QRS which by virtue of its bandwidth has a
high level of immunity to wideband QRM, and (2) there is very little activity at
the times the noise on on - note that VE1ZZ used a much lower frequency. I
think this will make it much more difficult to receive a WOLF transmission than
QRSS. I suggest that Larry uses a frequency closer to the 'data' allocation,
say 137.400kHz.
I am keen to listen for Larry but these two obstacles are making it not
worthwhile at the moment.
