Hmmmm....my statements may be somewhat misleading or incomplete! The Orion
will handle full QSK with the Titan 3. However with the Titan 3 in the
Keying Loop of the Orion, and running v1.371, the Orion will randomly either
lose RF output power or will randomly lose the rcvr (signals drop out almost
completely) and the audio from  the Orion. Dropping back to v1.369 and this
function works OK. I've made sure this is fully documented with
rfsquared.com . I presently have two Orions and they both perform the same
way.

It is not that the Orion will not handle full QSK, it is the above mentioned
random glitches that happen ONLY when the Titan 3 is in either Keying Loop
#1 or #2.

The Titan 3 operates excellent full QSK with both an Omin 6 and an Omni 6
Plus and a modified Corsair 2. I have been running the Titan 3 with my old
Omni 6 for the past two weeks and they both work flawless.
