[TenTec] QSK-5

[Steve N4LQ]

I bought an external QSK-5 and ended up blowing the front end out of my rig. 
The instruction manual is non rig/amp specific and requires allows for a lot 
of interpretation and requires some rigging. Since this happened, I've run 
across 3 other hams who had the same experience so I'm not alone! BTW: I was 
using an AL-1200 amp. Many others have bought Ameritron amps with the 
internal QSK-5 and had good results. Perhaps there is less room for error 
that way. And yes, "theoretically" you should be able to use it with any amp 
you mentioned by just leaving the amp's relay activated.
Personally, I won't try another one. Depending on some light bulbs and 
diodes to protect an expensive rig is too risky. My latest QSK QRO 
arrangement is a slightly modified Omni VI with it's tx key voltage driving 
a switching transistor which in turn keys an Icom PW-1 amp. The PW-1 is 
totally automatic and remote controlled. The amp is terribly noisy with it's 
4 loud fans and keying relay so I installed the amp on the other side of the 
wall and have a totally silent, automatic QSK system.

Is anyone with a TenTec rig using the QSK-5 adapter with a non-QSK amp?
If I get this gizmo, does it really allow...say an SB220 or TL922 to operate 
in QSK mode?
So I guess the loud T/R relay in the amp just stays closed, and the QSK 
gizmo has the antenna connections on the back...doing the switching instead 
of the amp??
I am just wondering if it would do the trick, or ...keep saving for a QSK 
amp??

Thanks for your time!
...Dave
