I think that the RTTY i heard was the adjacent HWU or one of the Russian stations on 18.1 kHz. Interestingly, it's not there all the time. It comes up with a pre-amble, sends traffic and then goes of
Hi Dave, In case of RTTY it was part of the RDL-Chain, 18.1 kHz from various locations. See: http://www.vlf.it/trond2/15-20khz.html Some sites: http://maps.google.de/maps?ll=44.77259,39.547051&z=14 h
