[Premium-Rx] Watkins Johnson DMS 107-1 manual needed

The IF and demod information is in Appendix S of the supplement manual.  
The IF and demods are the same for the regular and S1 models.  If your 
radio is not an S1, just ignore the brief mentions of the S1 
capabilities in the supplement.  The IF and demod cards are identical 
for all versions

It has been many years since I sold the last of these radios I owned.  
But as I recall, the fifth slot (rightmost button) must be a wide 
bandwidth.  I don't recall the exact restriction but it was something 
like >100kHz wide.  Other than that, the bandwidths can be installed in 
any order.

The B and B(S1) versions have a dip switch for configuring the radio to 
5 or 10 IF bandwidth.  They cannot be intermingled.  The radio must be 
all single IF (and demod) cards or all dual IF (and demod) cards.

Best,
Terry O'
