Hi LF,
I have noticed a strange occurrence when looking back at my extended
frequency range of captures.
In most of the interfering periods the strongest signal has not, I repeat -
HAS NOT been at 518 KHz. Yes a 518 KHz signal has been present quite weak
but amongst the splatter the spurious signals on 514.5 & 513 KHz have been
very strong along with a very strong un-modulated signal on 516.525 KHz.
There have also been five similar spurious but weaker signals radiating into
the 500 KHz band but originating from a lower frequency than my SDR Rx can
is monitor. ie, lower than 489 KHz.
I am keeping all the captures & will continue to monitor & capture until the
problem is resolved.
Regards,
Gary - G4WGT.

Might be worth attaching one of the spectra that have been circulated on
this list, plus some of the other supporting details.
