Dear Walter, LF Group,
Rather belatedly a report on DI2AG –
quite a good signal here since 1st January, best after dark but
sometimes also visible during the day. The SNR on the spectrogram reaches as
much as 30dB in a 0.3Hz bandwidth. Sometimes during the night, the CW ID is
audible over the “FW” beacon about 50Hz down the band. Like others,
I also see rapid QSB here, more like HF than LF.
The screen shot was obtained using an
RA1792 RX with a 3m x 3m tuned loop – this set-up is not ideal, I can
hear a considerable amount of intermodulation splatter from the nearby MF
broadcast stations, and I am not sure yet if this is the fault of the receiving
system, or an external “rusty bolt” effect.
Cheers, Jim Moritz
