It may be more reliable, but I've found my Orion I running Ver 2.056 (DSP
2.01b26) occasionally "wakes up" in the state Eric has described. I hear it
most often on 17m, and, as he noted, power cycle fixes it. I've never had
it happen after the rig is on and operating properly. So, it appears there
is a possible hiccup on power up that will still cause the 'feature' to
happen. It's easy to tell - there is no signal audible on the band, and no
noise pulses (which are abundant in my neighborhood), but otherwise it
sounds normal with background noise, etc. So, here's another data point on
that, for whatever it's worth.

Eric,
This was the reason for tentec coming out with V2. As I understand it, the
following was tentec's position on this. There was a timing problem in V1
that could not reliably be fixed. V2 instituted a radical design change in
how the front panel and 2 DSP processors communicate with each to remove the
timing issue. In V1, each microprocessor had to know what the others were
doing all the time. This proved to be impractical and resulted in various
lockups because of state tables not being updated with 100 percent accuracy.
In V2, each microprocessor stands on its own merit and does not need to know
what the others are doing. This is a much more reliable design point.
