Hi Laurence,
Condx are EXCELLENT on LF/MF. Do you see
real chance for our path this night? If so, which mode would be preferred? And
are you RXing or TXing at all? :-)

Chaps/chappesses -Looking
at my results here overnight I have just too much thermal drift with my
present driver for the 30 mode - the issue is my trusty FT817 driver using
5MHz IF that even with a TXCO is...too drifty. JT9-5 is fine - But hey
it may have been pretty on an Argo/SL screen :-)
The environment is
rather hostile for radios - temps are around 0degC in the garage even with
heat (that I can afford anyway) so from long off periods the radio cools
even internally..I need to being the lot back in the office/shack - but real
estate is rather limited and Im in deep negotiations with the
boss.
Its fine with the "faster" modes but I have some work to do
with the 850 and other drivers - it was just a stop gap to get me on the
air. Ill dig out the ZL1BPU DDS and continue to work on the 850 external
locked ref oscillator doubler board.
Ill run JT9-5 for a while today
for testing purposes - dial 136, tx plus 1100Hz (carrier 137.11 appx)
