After all, narrow IF filtering and CW isn't rocket science. I don't think your QRM busting technology is cutting edge.

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. John
