Jim,
Re day-time land-path cw sigs; they are there but
the limiting factor is site noise-levels.
I have solid/steady copy of kev but with little
noise-margin - a few dBs of noise would kill it.
Also, fluctuating noise-levels can give the
impression of qsb on weak sigs.
I have an mp3 [280k] recording of mal/chris at
10am, if you're interested? [~240mls].
73, Rog.

Dear Mike, LF Group,
No sign of your signal here in IO91VR
north of London yet. I was watching my own beacon signal on GM4SLV's handy
screen grabber overnight. There was pretty consistent reception without much
fading while the path was in darkness, and nothing at all in daylight. I have
not heard anything much over 2-300km during the day time here; to me it
really seems that the ground wave signal levels "fall off a cliff" much
beyond that over land, although the fact that GM4SLV, G3KEV and other
stations near the coast can hear each other during daylight seems to confirm
substantially greater ground-wave range over the sea. All the DX reports on
my beacon signals so far have been during darkness; and the distant signals I
have heard have been then too, so it looks like the ionosphere is only really
cooperating at night.Any possibility of operating your beacon after dark
would be welcome here - the 503.8 frequency is fine by me!
Cheers, Jim
Moritz 73 de M0BMU
