[TenTec] Orion Sub Receiver getting no signals

[mcelmer1]

Howard,

I am using 3.032x5 V2 July 2013.

Switching to Ant 2 does not solve the problem. NB/NR/Notch/SAF/AN are Off as 
is the SAF/Notch tracking.

Also, there is no audio for the Sub receiver (or internal speaker) when 
headphones are used. Left/Right Audio is set to BOTH.

The BARGRAPH immediately to the right of VFO B Frequency does not move when 
the sub receiver is used. The Bargraph does function cuz it switches to SWR 
in transmit. The thin bar below the Bargraph does move when Sub AF 
knob/encoder is adjusted.
