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 tru=
sty 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 :-)=20

The environment is rather hostile for radios - temps are around 0degC in th=
e 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 offic=
e/shack - but real estate is rather limited and Im in deep negotiations wit=
h the boss.

Its fine with the "faster" modes but I have some work to do with the 850 an=
d 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 oscillat=
or doubler board.

Ill run JT9-5 for a while today for testing purposes - dial 136=2C tx plus =
1100Hz  (carrier 137.11 appx) -=20
