Hoping someone can identify the following military radio.
I spotted it at the curb and decided to make it a land-fill diversion project...
One of the fine folks from MMRCG identified this as model R-1484/PRR-15
This is indeed a R-1484/PRR-15, also known as AN/PRR-15. Made by Zenith, circa 1969 for USMC sigint use in Viet Nam. Probably fewer than 100 made.
