Hi all
There is an interesting info in this message for me. Jim says that Saturday
morning was very noisy and Sunday was much quieter. Me (and I belive Rich
too) have opposite experience. Saturday was quiet (and I made a lot of
QSOs), it got much worse in the evening, QRN lasted all the Sunday morning
and it got better Sunday afternoon. It looks as if the source of QRN moved
accross Europe, from the west to the east.
BTW, is the QRN same on the land and on the sea? If not, inland coutries
like DL, OK, OM, HB9 are bit handicapped.

Dear LF Group,

Weekend activity here:

On Friday night I was on 71.620k for testing, then some time after
midnight I changed to 71.924k until around 0400 to join G3AQC's
transatlantic beacon.

Saturday morning was very noisy, and it got worse through the
day. Although there were lots of stations on, I could not copy much
DX under the QRN, although I did work EI0CF who was a strong
signal. I could see OM2TW's signal on the spectrogram screen, but
could not hear it at all. By the evening, I was struggling to copy
G8RW, who is quite local to me.

On Saturday night I did some more antenna tests on 136.923k
around midnight. This was with about 250mW ERP, although I have
not worked out the figures in detail yet. This is probably what
CT1DRP's plots show, and what DF6NM saw.

Sunday morning was much quieter, and I could hear OK1FIG call
CQ several times; I replied a number of times, but no QSO.

On both days I could hear signals centred on about 137.4kHz,
which were a sort of "chirping", a bit like the strong signals just off
the bottom of the band. If they are a new signal on this frequency,
they must be quite distant, since they weren't much above the

I have now got FS measurements on 73k as well as 136, and with
the antenna configured as an 8m high inv. L, or as an inverted V
jacked up to 17.5m in the center. I will post more details when I
have worked out the numbers.

Cheers, Jim Moritz
