[TenTec] Orion II manual / firmware for 565 / 8P with Orion II

[Martin, AA6E]

Schematics are not published yet for the Orion II, are they?  I don't see them.

In any case, the same clock oscillator seems to be used for the Master
and Sub CODEC in the Orion 1.  I have not noticed a frequency offset
when (a few times) I have used diversity Rx.
