Subject: LF: 504khz harmonic.
Occasionally recently I have been seeing
strange patterns around the harmonic line received on my SpecLab grabbers on
504kHz from the broadcast station at 252kHz.
The patterns are not just seen using the
Softrock SDR Rx but also with my JRC NRD-345, the only common device is the
Mini-Whip active antenna.
I seem to remember some while ago comments
on this LF Forum regarding that station carrying out some experiments or tests
involving digital data or something similar.
I wonder if this is an effect of those
tests as there were concerns that it may cause interference on the 500kHz
