Hi All!
Please note that SBDVP.EXE by W9CF was written to work with TRLog by N6TR.
It probably doesn't work with NA or CT, but you could ask Kevin Schmidt
about it at w9cf@ptolemy.la.asu.edu .

No, I use a 2:1 step-up and isolation transformer.

I use the command line:
sbdvp -m2p1 -p1n2
the -p1n2 makes the DVS switch to the internal mic circuit during record.

The latter, just like the normal CW keying transistor, including the 1 Kohm
base resistor which goes to pin 16 for PTT control by TRLog.

No, the radio has an internal pullup.
