In addition to muting the receiver, the PTT line should be closing
the AMP KEY line to your amplifier. I agree that the radio still works
in QSK, but of course you can adjust EXT T/R Delay so that the amp will
still work in Semi-Breakin in case you forget to depress PTT. As I
recall,
this is exactly how my MP worked. Although my preferred mode was to
press my footswitch, Semi-breakin was there to "rescue" me in case I did
not depress it fast enough for the computer keying (I also use manual
keying
in parallel with CT for contests).
Bottom line to all of this is Orion's PTT should definitely be
closing your amplifier's T/R relay in addition to muting Orion. If it
is NOT doing that, something is wrong with your setup, but it works fine
for me. This is what I expected when I first set up my Orion last
August,
and was very disappointed when my footswitch via the MIC connector gave
me a key-down carrier on CW! Thanks to Ten-Tec for listening.

I hadn't noticed that the amp T/R line was being keyed as I didn't have
the amp on. I've just checked and it is doing so, exactly as you
suggest. I tried out this feature because it is new, not because I need
it as both my amps are QSK. I have to say I am still puzzled. I will
be interested to see what others have to say but it seems to me that QSK
continuing to operate in PTT mode is inappropriate. Isn't the purpose
of PTT or MOX control is to ensure you can't transmit unintentionally?
I don't want to diminish what Ten Tec have achieved here but it does
seem they are only 80% there on the implementation of this. A TX
inhibit is required to finish the job.
BTW does your RIT set on Fast now have that "dirty pot" feel?
