I may be wrong but when folks make reference here to PTT I don't think
they necessarily have in mind a physical "push to talk". Many contest
stations are set up such that TX/RX sequencing is under the direct
control of computer logging software. Some eminent contesters seem
concerned that breaking this link could introduce unecessary risk to
expensive hardware, operating under extreme conditions.
Now come on guys.......lead on with the "I don't need that, I don't
understand that, I don't want that, Ten Tec shouldn't do that.....buy a
different rig......I'm starting to enjoy the refrain!

Of course I agree with Jack that on HF, QSK is an abolute must for
reliable operation. It has nothing to do with PTT: Be sure, I'll not
use a PTT for CW contesting, I only have two hands, one for the PC,
one for the keyer, that's all...)
On VHF, as Duane explained well, QSK is not that easy as on HF (even
if the situation here is not worst-case: Power is medium, and no
preamp's used due to the short feedline), but of course nobody will
use an extra PTT on nowadays rigs..
Thanks to Carl it now seems sure to me that I could use semi QSK
easily with the ORION, just as known from my actual equipment with
using the TS850...
So again thanks a lot for the help.

Semi-breakin on the Orion is easily done by using the QSK
adjustment. There
is also a variable delay that can set to hold amplifiers and
transverters in
the transmit position for up to 1 full second after keying is over. And
keying the Orion is delayed 20 milliseconds to allow the external
relays to
transfer. So no keying problems should occur for you.
