[TenTec] Orion II interface

[Ed -- GW3SQX]

I'm using Pin 4 of the "Aux I/O" socket on my Orion II as input to the 
MicroKeyer, and thence to a PC.  Although the Orion documentation (page 26) 
states this is a "line level" output of 600 ohm, 1V P-P,  the level 
(confusingly) also seems adjustable in the "Other" menu, and is mentioned as 
such on page 34.  However, the actual level varies with the "Main AF" 
control -- not what is needed for input to a sound card, for example, and 
not really usable for digital modes.  Or am I missing something?
