Yes I did & I cannot detect any difference from the pattern being there= or not.

Hi All,

 

Occasionally recen= tly I have been seeing strange patterns around the harmonic line received on my SpecLab grabb= ers 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 amateur band.
