[MRCG] Collins 500-z4 filter

[Daniel Jones K6YIC]

I picked up an extra module for my PRC-47 and am looking for the 500-z4 filter so I can switch it to LSB.  I want to do this because my CV-2455 that I run is a Mark High version that was never modified.  Switching to LSB will flip my signals for RATT and give me LSB capabilities.  

So does anyone have a 500z4 filter they wouldn’t mind parting with.
