[TenTec] Corsair II - Filter Classtime Please

[Bwana Bob]

If it's like the original Corsair, there is a 9 MHz 4-pole filter in the 
first IF (upgradeable to an 8-pole filter) and a 2.4 kHz filter in the 
6.3 MHz second IF.  The 6.3 MHz filter gets switched out and replaced by 
a 1.8, .5 or .25 kHz filter.  The jumper bypasses the 1.8 kHz filter 
slot if this filter is not installed.

             73,
