I suspect by now this has been solved.

I hope not, we dont need any of that kind of discussion as I see it......

This is a regretable situation.

The 136.5 frequency as used by VE1ZZ earlier this year was the subject of
extensive discussion that was not complimentary as to the location with the
European 136  Band Plan.  I choose not to tempt fate by transmitting in that
area.

"'data' allocation" that must be part of a European LF Band Plan that
apparently does not consider North American requirements.  There is no way I
would transmit 400 Hz from CFH, that would be an unwise move even if I did
it once just for fun - it would not be taken well.

I did operate on 137.75 and that was a problem because of the European LF
Band Plan, I moved, based on a strong recommendation up to 137.790.

137.790 is clear in ZL and VK and I do not have at the moment a way to
remotely change the DDS frequency in any case.   If I was to move over 1 kHz
I would have to retune the loading coil for optimum output and while I now
have a tuning mechanism to do this I do not have a driver motor that will
survive being exposed to the elements.

If the WOLF transmissions are not going to be readable in Europe we have the
option to change the time, or add another hour at a different time, or the
digital session can be ended if it is not being used by anyone.    Comments?
