My software also now offers a main/sub calibration. I am finding my Orion
II shows a consistent 6 hertz difference between the 2 receivers. My
software now perfectly corrects this when in diversity mode.

Well, maybe it's necessary to think outside the box a bit.
While it may not be possible to phase lock the receivers, perhaps it's
possible to get a bit closer through a fixed (or variable) calibration
adjustment. N4PY offers a "calibration" feature in his remote control
software that permits setting the display to the correct frequency when
the
master reference oscillator (and thus display calibration) is off a tad.
I've always thought this concept could be applied in T-T firmware to
prevent
the need to tweak the master reference when the radio is off a few Hz,
and
perhaps it could be applied to the Main/Sub difference as well -- not a
phase lock soltuion, but not off 6 Hz, either.
Seems straightforward, but I could just be slow -- and I'm sure many
would
agree the latter is the case :-)
