Dear LF group,
Thanks to all those who sent reports of my 73kHz signals last night.
I gather DF6NM was trying to call me for a cross-band QSO;
unfortunately I was not actually set up for X-band operation last
night, so was not able to see Markus' signal, but I will certainly sort
this out in time for next Friday, or any time people would like to try
for a sked.
I did not hear anyone else on 73kHz last night - however I did hear
a signal that was new to me. It was on about 71.70kHz, and
consisted of short "pips", a bit like one of the time signal stations,
except that there were about 40 pips per minute, which seems like
an awkward number for a time signal. It was barely audible on the
transmit antenna, but was several dB above the noise on the loop
antenna. Some pips were louder than others, a bit like the Russian
Alpha VLF beacons speeded up. I tried nulling the signal with the
loop - it was hard to find a null due to the noise from Rugby, but
was roughly north-east/south-west from my QTH. It was still there
today. Has anyone else heard this? Any ideas?
Cheers, Jim Moritz
