 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...........

Thanks for the confirmation Mike.

Like you I am concerned about transmitting within the RTTY signal.
I was looking at the images from Johan and John recorded on the 10/Sept and 
noticed in one from John that a wide band of noise is visible just above the 
QRSS. It looks like the edge of the Greek data transmission. As it's about 
the same signal level it would seem sensible to avoid it.

a long way from SV land we are considerably closer to the Greek embassy, 
ships at sea etc etc.

135.780 and up may be better ( 5Hz spacing? ). Personally I'll avoid the data.

Also received Jack (T) at 00.00 on a 30ft vertical.
