I make it 135.673 and 135.773kHz with a lot of noise in between. 
Using frequencies in the 135.7 region (ie the middle of the RTTY) is 
a bit like Canadian stations transmitting on 137.000. Is this really a 
good idea? I would have thought that even the noise sidebands from 
SXV would be very significant compared to Eu amateurs.

I have attached a small JPG to illustrate this. The band edge is in the 
middle of the noise and the clear section is below the RTTY (HF) 
between 135.850 and the line which is on 136.000.

It is really up to John, Jack and Larry to say where they prefer to 
listen, but the area currently in use looks really bad from this end.
