Hello Wolf,
Thanks for your offer of help!
I can offset the VFO to accommodate most anything within the SSB bandpass,
but how is this?
1000 Hz = dit
1020 Hz = dah
I use USB mode setting and then add 1 kHz to the TS450 display reading
(27.555.73 - 1 = 27.554.73 display for carrier and dit freq.). I then
divide the results by 200 for converting ~27,555.73 kHz to ~0.13777865 kHz,
I will have a 0.1 Hz separation between dit and dah.
Is 0.1 Hz. the correct separation?
Is this enough information?

Hello J.,
Which audio center frequency (in Hertz), and which DFCW keying speed do
you need ? I could prepare a config file for you to send QRSS through the
soundcard, using the serial port to key the transmitter.
The difference between "dits" and "dashes" can be set to anything you like
on SL's "digimode" terminal (it's "frequency shift or span" parameter on
the digimode config screen).
Cheers,
Wolf DL4YHF .

Hello again, All,
Spectrum Lab apparently will have a very large learning curve toward
success for me. Success means to use the software to key the PTT on the
RTS line for DFCW transmissions, and to shift the AF by 40 Hz. up for dah
and back down for dit. The 40 Hz. shift is necessary because a divide by
200 is used between the TS450 transceiver which acts as the VFO and the
137 kHz. output which drives the amp.
Is there s quick primer on someone's site which shows how to set up DFCW
only?
Thanks,
J.
