[TenTec] Head-Phone volume in Orion2

[Ron Castro]

This is a well-documented problem in the Orion II that has to do with a 
different attenuator/chip scheme between the speaker circuit and headphone 
circuit.  It's not impedance related, although large deviations from 32 Ohms 
or using low-sensitivity headphones will make the problem worse.  The newest 
firmware version, 2.041XT brings the two levels closer together when used 
with the 'IF AGC' setting.
