with a Dovetron FSK-1000 yes although I use a separate
set of 4 individual constant current HV loops at 60 ma
for the heavy metal keyed by MJE-340 transistors from
the logic level output of the Dovetron.  Remember to put
a .1 ufd cap and 470 ohm 1 wtt resistor is series across
the emitter and collector to protect the 340 from inductive
spikes.  I do NOT have any kbd or TD in the HV loop,
just printers and prefs/reperfs...I use "dry" keying from
each kbd and TD to the logic level input of the Dovetron.

So far no probs.  Lots of freeware and shareware software
out there for using any TU on a serial port, including PTT
from the software when a key is pressed as well as CW ID.
