Dave,

Mighty fancy but, being ignorant about most W-J, I wonder:

- What does it accept as inputs?  RF? IF - what frequency?
- Does it drive RS-232 type output, or 60 ma loop?  What?

I do have one W-J (CEI) receiver here, a vlf unit: VLF-354.  It has the 
tape readout, covers from a few kc up to 600 kc, and has an IF of 2 mc.  I 
am looking for a manual for this one.  I do have a manual for the 357 which 
is very similar (has nixie readout).

Roy
