any help please.
I find the same thing as well. Also the case when I have the DEMI turned on and key the HF amplifier; the DEMI is also keyed.
Don't have the equipment but this logic also implies that if there were 2 or more amps/transverters they would all be keyed.
Even if we could individually trigger these lines, XVTR Table or similar, there are still only so many TX lines available.
