GM Mike,
I think I will pass on this one.
This is not going to be a PLUG'n'Play solution.
Bob seems to know them.
I 'remember' seeing them when I was a kid, but I left the states soon after
that and never saw one again.
In general, if you want to run QSK with a NON-QSK Amp, you will need the
QSK5.
The Model 318 has no way to speed up switching inside the amplifier.
It just slows down the switching when returning to RX mode, to PREVENT the
amp from "trying" to follow the QSK switching.
In other words, the Model 318 enables "Clean Semi-BK", but with a caveat.
The amp's relay can't be too big and clunky. If so, it won't be happy with
the 15mS pre-dit time which is a fixed value coming from the Orion. For the
Eagle, it's 17mS.
TEN-TEC, PLEASE INCREASE THIS TO "20Ms" or better yet, "22mS", AND THEN IT
WILL WORK WITH JUST ABOUT ANYTHING!
NOTE: the specs on most open frame relays are something like 15 to 20 mS
switching plus 1 to 2 mS settling time, depending on make and model.
The QSK-5 actually does enable QSK switching, at least with most amps, but
in the case of the Thunderbolt, you will need to add additional hardware.
By the time you do all that, it may have been just as easy to pick up a
second, used amp.

Hi Rick, sorry, I forgot to include that the rigs are Corsair II and Johnson
Courier or Thunderbolt. Was hoping to use the amp with QSK.

Mike, these are two totally different animals.
The QSK-5 speeds up the amp switching, while the 318 slows it down.
Both solutions can work, but it also depends a bit on the amp and how fast
its relay switches.
What rig and amp are you trying to mate.

Tentec friends, I am looking for help comparing the TenTec 318 with the
Ameritron QSK-5. Has anyone used either/both of these who could offer some
insights?
Thanks and 73
