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
