Good for you.

I've no idea, perhaps they don't suffer as much as you imagine, since they
probably also have narrow CW filters, like you. After all, narrow IF
filtering and CW isn't rocket science. I don't think your QRM busting
technology is cutting edge. Perhaps others have discovered the knack too?

I haven't the slightest interest in chasing RTE for their 2nd harmonic, as
I find it's a useful indicator of propagation to the south west.
I have even less interest in chasing Loran, since I don't operate on 137,
and never will. Are the Loran problems on 137 a result of faulty
transmitters or simply a result of sharing the band with other, more
powerful, wideband systems?
The Utvarp Foroya 531kHz problem was because of seriously mis-adjusted,
brand new, transmitter and was worthy of tackling.
The other things you mention have been around for a long time, nothing's
been done, presumably no-one cares enough, myself included.
If you feel otherwise then here's a clue - get on with fixing it, or
