SUB-RX line out low

alsopb
I seem to recall another post where someone said the line out level for
the sub rx was considerably below the main RX line out level.  Couldn't
find it in a NABBLE search.

Using firmware version 2.82 now.   Also line out = phones.   Normal
listening levels on main have the AF gain at about 9 o'clock.   To get
similar line out levels on the same signal from the sub requires about 2
o'clock settings.

I can't recall having compared these levels before.

May have shot myself if the foot here.  Installed the leaded line out
resistors yesterday.   Despite checking it 6 times, there could be a
wiring error.

Before opening up the box again,  I thought I'd check here first.

I might add that historically I've had problems with line out from the
sub-rx.  One fix was to replace the stereo radio shack plug with
another.  It could also be that the jack on the I/O board is flakey.

Please ignore the following post.

Got out the scope and looked at outputs.  AOK.
Problem was with the way Spectogram was inserted in the circuit in a
stereo environment.
