Hello Markus    I dont think things are as hopeless as you think   in the first
place I would expect that the bandwidth of the Greek station is concentrated 
over
2 or 3 kHZ.  The power is concentrated in the spectral lines caused by the
keying. The lines are approximately 90 Hz apart,  with little energy between the
spectral lines.  I saw the main line often this summer and fall when looking for
Eu signals but didnt knoe what it was.  I believe if you look at the  picture I
sent over of G0MRF sending RO  and OOO,   you will see the carrier of the Greek
station.
     I am afraid that CFH can come on at anytime again in the near future and i
am also afraid That 135.7 will be better than 135.9 at Jack's QTH as he lives
much closer to CFH than I do.
      I think Jack may have a xtal for 136.0 kHz
      I would prefer that anyone trying to come easst to North America would use
135.7 to 135.8

      Will anyone want to transmit tonight or tmw nite?

... I'm afraid its an illusion that any of our amateur signals will make it
across on top of SVX. Just consider: If it has say 10 kW spread over 100 Hz
bandwidth and _if_ it is attenuated by additional 10 dB traveling over the
continent, this would still be the equivalent of 5 W in a BW of 1/2 Hz. If
John does not hear it loud its simply due to the fact that condx to EU were
not good enough for a contact.

So my opinion, for a penny's worth: As long as CFH is off, let's use the qrss
segment at the upper end of the band, between 137.77 and 137.8. When CFH
comes back, stick to the 135.9 ... 136.0 plan.

Happy New Year, take care
Markus
