Have a bash on 137. It is superior to 500 khz.. Reliable communications during daytime all around EU, no need to wait until dark for a QSO.
You would be in demand especially from the Shetlands. A big DX attraction.
A cw qso to Moscow or the USA and Canada would be the norm.
The band is also international and not restricted like 500. A few years ago there was an abundance of EU stns actrive plus Russians and North Americas. Look to the future beause 500 is not expected to last. The Japanese Nagyokosak consortium are developing a worldwide communications system to work in conjunction with Satellites for marine/aero useers. I understand 500 is currently in use in Asia for marine communications and will expand over the next several years.
Buy some japanese shares if you are a gambling man.

I can work through the loran on 137 and rte on 500 with narrow cw

Good for you.

was just wondering why those most effected have not
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?

Since you are now in full swing chasing faulty transmitters and know the
procedures have a bash at sorting out loran and rte, there is no point
anyone else re inventing the wheel. GO FOR IT John.

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.
