The HF-2500Dx does not have a TX EN "ready for transmit" output. As such I 
would have to assume the high speed switching&nbsp;employed in the amp&nbsp;is 
engineering to handle the exciter power on key up.


Or, the Omni VI delays the generation of RF when the RELAY function is 
turned on. My manual does not describe this as clearly as I would like 
it to. It does say that when the relay function is turned on, the SLOW 
QSK delay setting becomes the relay hang time. It does not say that when 
the TX OUT to TX EN jumper is in place and the relay function is turned 
on there is a delay time between key down and the relay energizing and 
the beginning of RF output. Those Ten-Tec guys are pretty clever, so I 
would guess that they thought of this.

Using the RELAY to key the amplifier certainly will work, and provide 
some degree of "QSK", though not quite as good as using the keying loop 
method. There are some on this reflector who claim that if a relay can 
be heard, it is not QSK at all.
