Hi, as owner of a number of classic TT rigs, the omni a/b/c does have
a keying line for non qsk amplifiers.... there is a delay that can
be adjusted, a trim pot....
this is vastly different than the T - voltage output at the accessory
plug..... that is used for QSK, with TT amps, I use the original
Hercules 444.... that is the sequential voltage for control
circuitry from tx to rx, is not adjustable....
you can even run the herc from the 540 and 544 by using the T
voltage..
with the 540/544, of course, the band switch of the rig does not
operate the bandswitching of the amp, the Omni c does control that
feature of the amp, not sure about the omni a/b

I've got the 444 manual, can provide info for those who want it.
