Krish, I'm with you. I wish we had a bunch of SDRs on phased monopoles tied together via TCPIP so we could triangulate the culprits. All the time and money these DXers do to provide the DX community with a new one gets destroyed. It appears some smart people are doing it because I can see 10-20KHz swaths of noise QRming the DX station(s). Obviously a SDR type radio with some funky type of modulation. Nobody is going to do anything about it because there are "no resources" to do so. "WE" have to do it ourselves, somehow. It is only going to get worse. It should be "JAIL" for them, period. If you did this 50 years ago it would be treason.
LOL. It gets me that mad(so they are winning). My favorite life long hobby going down the tubes. I'm sure I speak for a lot of us DXers trying to fill up our log books. Are there any forums or sites dedicated to finding QRMers? May the radio gods destroy their wide band transmitters and melt their antennas.
