[Premium-Rx] Re: panadapter/sdu for harris rf-590?

[Terry O'Laughlin]

One of the better SDUs for this application is the WJ-9188A.  It is 455kHz 
at 30kHz maximum bandwidth 3-1/2 inches high and 1/2 rack width.  There are 
some Reaction Instruments units that are smaller (1-3/4" high) and have 
more options (multiple input frequencies), but I have not used them.

WJ made a number of 455 kHz SDUs that would work.  I used an old vacuum 
tube CEI SM-8512 on the 455 kHz output of my WJ-8718/MFP for years.  The 
nuvistor units like these drift a bit but work fine.  They are much less 
expensive than the WJ-9188A and much better displays than the WWII vintage 
SP-44.

Best,
