Hugh,
yes Mike is right about the low end of the
band suffering from QRM. If you could go up to the "Eu slot" (136172
+- 3 Hz, close to a spectral minimum in the HGA sidebands) you'll find
several grabbers watching continuously for slow QRSS. Using daytime
groundwave, Stefan and I were able to see each other across 180 km with ERP down
to about 2 uW.
73, and good luck for your
experiments,
Markus (DF6NM)

Hugh,
What is your default mode? Will you be
beaconing or calling CQ? What
should I listen/watch out for?
The
choice of frequency is a little odd, there are S9 sidebands from
the HGA
telegrams and S5 RTTY from SXV which will be very strong
after dark. Are you
crystal controlled? 1kHz further HF would be much
better.
