[Premium-Rx] WJ 357 A4 Varactor Tuned VCO Module

[Faulkner-Sarmont]

Hello List,

I've come across something I need help finding.  I recently did a receiver 
swap for a WJ 357 1 to 600 Khz receiver for my VLF receiver array.  Upon 
arrival I discovered the factory A4 varactor tuned VCO module had been 
replaced with a homemade VCO module.  Upon followup the receiver's history 
traced back to the WJ 357 having been slaved to a 2nd WJ 357 by a 
government agency.  Anyway, would anyone on the list have info on where I 
can find a proper varactor tuned A4 VCO module for my WJ 
357?  Thanks,  Leland  NC9K.  I can be reached off list at NC9K at hotmail.com
