[GreenKeys] 850 Shift

[Tom Hunter]

Paul,

You should not stop work. There is much experimenting to be done. On a
hunch I am running 22050 and 16K to accommodate the wider bandwidth, What
will be the minimum bandwidth for 850?

I cannot copy the tones directly from the RTTYApp computer on MMTTY running
on another. I have a perfect waterfall display but no vertical line on the
pulsecross.

My old Dovetron will not tune to 2975 so I cannot test it on a TTY. I have
a lot to do today.

I have my dual function generator set to 2125 and 2975 to check filters.
Next I want to try a Heathkit HD-3030.
 on 850 shift.

I woke up with the bright idea of running a dual shift stream with mark at
2125 and space at both 2295 and 2975.

Much experimenting!
