[TenTec] Omni VI+, Henry and QSK-5

[Paul Christensen]

Jim,

Based on your description of the operation of the QSK-5, I am guessing that the following interconnections "should" work:

QSK-5                            OMNI 6

AUX    <=========>   TX EN
KEY 2  <=========>  TX OUT

It would appear that KEY 1 should be strapped to AUX only if you want to run the amp with the QSK-5 switch turned off.  OK, I give
up...why would anyone do that if it puts you back to where you were without the QSK-5?  In any event, the QSK-5 would then complete
its handshake back to the Omni 6 via the AUX<==>TX EN lines.

What's bothersome to me is not knowing the open circuit voltage of KEY 1.  The Omni's TX EN open-collector jack can handle Vceo up
to about +30 VDC.
