The only real issue I have seen with V1.373b5 stability is the occasional loss 
of the subreceiver audio. Because of the otherwise exceptional performance of 
this firmware, I started trying to find a "workaround" for the loss of 
subreceiver audio. I usually only listen to the main receiver audio but switch 
to Main in the left ear and "both" in the right ear when I am looking for where 
a DX station is working in a pileup. So I normally kept the subreceiver audio 
"off" and only turned it on when I needed it. I tried looking for "keystrokes" 
that might "revive" the subreceiver audio, but I couldn't find a reliable set 
of keystrokes - ones that always worked to revive the subreceiver audio. The 
next thing I tried was to use an outboard "audio manager" to allow me to switch 
the Orion audio channels outside the Orion. I am using the NCS - 3203 Multi-RX 
II (New Communications Systems). I am sure there are other ways to achieve the 
same thing at lower cost. The NCS-3203 allows me to l
 eave both the main and the subreceiver audio on all the time. I use the 
NCS-3203 to switch the audio between mono (Main RX) or stereo (Main left ear - 
Sub right ear). I have been operating for several weeks in this mode - usually 
many hours a day - and I have yet to lose the subreceiver audio! Whenever I 
switch the NCS-3203 to stereo I get the audio from both receivers. While having 
one more box is not optimal, I operate a complex station with auto switched 
antennas, RX only antennas and preamps etc, noise cancellers and antenna tuners 
etc. So one more box is not a big issue. Not losing the subreceiver audio  - " 

Because V1.373b5 has notch filters that remove the carrier from the bandpass 
(notched signals don't pump the AGC and make copy of weak signals very 
difficult); has an excellent range of Noise Reduction options - particularly 
for SSB; has excellent quality audio (No overdriven audio distortion); a $250 
box to workaround the loss of subreceiver audio is a bargain. I would gladly 
pay $250 to get the bugs (Even without the notch filter fix) fixed in V2.062a. 

A couple of people on the list mentioned they thought they had an AGC 
workaround for the audio distortion in the latest release of the V2 code. As 
someone else mentioned, I would be very interested in hearing what those AGC 
settings are - settings where the normal harsh audio is heard and settings 
where the audio harshness is gone. Still hoping for a new V2.0 release - with 
bug fixes - in early 2008!
