[Orion] [microHAM] O2 AFSK (rear) with MicroHAM interface - bug?

[Richard Detweiler]

I have the O1,

I never could get it to work going to the aux input,  there is a drop in 
audio through the micro keyer,

I use the 'mic' input, ( swithed in the audio control ) then used mic gain 
to control the audio level,
worked much better.
