My sincere thanks to all those that have responded to my plea for
assistance with this problem. I reverted to firmware revision 1.366
yesterday and have seen no recurrence of the raspy sidetone problem
since then. Fingers crossed it stays that way. I understand from
several of you that this problem was evident in earlier firmware
releases. On the face of it, it would appear to have crept back into
Rev. 1.367. If it does recurr here under 1.366 I'll be sure and let you
all know.
I will be sending a full report to ditsnbits this afternoon.

I have an intermittent problem with my Orion which was delivered last
Tuesday. It may be that the problem is firmware related as I did not
see it before I updated to V1.367 On the other hand, it may be
nothing to do with the firmware. I wonder if any of you Orion users
have seen anything like this?
When the fault is evident the side tone develops a rasping quality
that I can best describe as having the characteristic you might
observe when an rf arc strikes up somewhere in the system. That is
what it sounds like though I don't think that's what it is, as the
problem persists even if power output is wound right down to a
minimum. Another thing I have observed, is that under normal
circumstances when the sub rx is turned on the sidetone level
increases as you here it from the output of both radios. When this
fault occurs then turning on the sub rx reduces sidetone volume and
turning it off increases it! The opposite of the norm. In both cases
the sidetone retains it's rasping quality. Sometimes turning the
radio off and back on will clear the problem, sometimes it does not.
Sometimes the radio works fine and then the problem arises.
As I have only seen this problem since doing the update to 1.367 it
seems logical to revert to 1.366 to see if that prevents the fault
arising. Does anyone have a copy of the 1.366 file they can e-mail to
me to try this? Anyone have any other thoughts?
Many thanks.
