[TenTec] Orion 2 SSB Filter Adj?

[Carl Moreschi]

I believe that is the exact point where the 2.4 hardware filter gets put 
into the receive path.  About 2.4 khz, it's not in the path.  There's a 
filter centering adjustment for each filter and that would allow you to 
move the filter a little either way.
