With my Orion 2.054 upgrade, the headphone audio can be reliably killed 
by the following procedure.
Place the sub receiver in AM mode.
Make sure T and R are on the main vfo, any frequency, any mode.
Touch the TX  Key or PTT.
The headphone audio does not come back until you either cycle power or 
else reset the sub receiver to some mode other than AM and touch TX 
again.  The speaker is unaffected.

This is not an RF problem.  Low power, Dummy Load, TX on SSB without 
speaking, all the same.

I believe the problem never shows up if you do not put the Sub receiver 
into AM mode.

The problem also does not show up if you reverse the process, that is 
main receiver AM and sub not AM.
I have reported to Ditsnbits.

I have no desire to go back to 1.372.  I like the "new" NR, AN and sweep.

Comment about the Speech processor. 

Start with 1. 
5 was way too high on my Orion with 1.372. 
The effect of speech processing is always to increase the average level 
relative to the peaks.  Many people believe that if a little processing 
is good a lot should be better.
The sure sign of too much processing is when the background noise 
between words rises to the level of the speech signal.  Intelligibility 
of the signal is drastically reduced.

With 2.054, I find that SP set to 1 or 2 is plenty.  At 3 and up the 
computer fan under the desk dominates.

I use cw on headphones *only* and have no such trouble with 2.054.

Was playing with the new beta release last night and noticed that, on cw and
wearing headphones, after pressing the cw key the receiver does not come
back on.  I get no further receive audio.  I can still hear it through the
speakers, but not headphones.

The only way I have found to recover is to turn the rig off and back on.
This is the same on the Heil and cheapie phones.  Had to reload the old
1.372 to get the headphones back for cw work.

The system as a whole is more responsive with 2.054, but audio seems to be
messed up, and there are still some glitches.  I'll wait for another
revision.  --Brent N9HZ
