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
noise.
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
