[Orion] Low audio in head phones

[John T. Fleming]

I have not used my Heil headset since last field day.  I tried them out this
evening, and the audio level on the head phone jack is very low.  If I plug
the head phones into the speaker connection, I naturally only hear in the
left headphone, but the level is normal.
 
I did the mod for version 2 software a while ago.  Does anyone know if there
is an internal volume control for the headphone jack that I might have
bumped?  Thanks in advance.
