Hi Rob, it has hardly been active in the last 5 years mainly daylight even
then.....humourously refered to as spider roasting. Occasionaly during the snow
and ice to clear the accumulations off the umbrella wires. We were expecting
more activity when the UK sold some surplus diesel subs to Canada.....must have
been around 2005 ..... unfortunately one had a fire off the north coast of
Ireland during the passage home, and I think their commissioning was deferred.
We never heard CFH regularly again after that. Originally 1999/2000 it was
transmitting rtty 82Hz shift FSK 24/7, but installed a new TX for multi-channel
msk around 2003/4 but hardly used it. The new mod is a lot wider than the rtty
but there seems to be at least 6 separate channels rather than the one on their
rtty. LF txs use a lot of electricity !!
I used to have some pictures of the TX and the antenna and tuning hut, thanks
to my "mole".....one of the techs on site. They are probably buried
on an old HD.
