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
ignore it.
