[TenTec] OMNI VI and fast switching amp hook up ?

[Carl Moreschi]

The timing will be wrong if you do this.  The omni VI will start
transmitting before your amp antenna relay has transfered.  What you need is
for TXOUT to energize your amp antenna relay and then use a contact on the
amp antenna relay to return ground back to TXEN.  This guarantees the amp
antenna relay transfers before transmitting begins.  This is exactly what
tentec QSK amps do.

> Hi-
>  I have an OMNI VI and a TL-922a amp which I just finished wiring with
vacuum relays for QSK fast switching. Works great but, the OMNI relay used
to key non Ten Tec amps is annoying on CW. (Not real annoying but....)
>  Of course when not using the amp, which is 99.9% of the time I can switch
the relay off and have quiet CW.
>  Is there any reason why I can't tap into the TX EN and TX OUT jumper with
a "Y" connection and run the quiet transistor switching to ground since TX
OUT does go to ground when its active and then leave the relay OFF?
