Hi Dexter & Bob
I lost all signal from the 73.3 kHz RTTY station by 0100 UT last
evening. QRN was very high so the signal could have been just below my
noise level. Relative signal strength logged are as follows:
2100 UT -52 dbm
2300 UT -48 dbm
0000 UT -47.5 dbm
0100 UT undetectable
0200 UT "
0300 UT "
0400 UT "
Bob, K3DJC, in Pa. also was hearing the signal.
Excellent! This can be the basis for monitoring 73kHz T/A propagation.
Expect ham radio signals to be about 30 - 35 dB down on this! (anyone who
would like to correct this figure - please do).
Propagation studies on 136kHz were done by Alan, G3NYK, who monitored the
Canadian Naval station CFH in Nova Scotia. See www.qsl.net/on7yd/ for
details.
This could be a good Lowfer project in the USA

Peter, G3LDO
