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
