[Milsurplus] FRUPAC

[Ralph Cameron]

I believe the designator was FRUPAC for Fleet Radio Unit Pacific. There are a group from the U.S. Navy intercept ops who meet on 7.234 daily at 1pm. Eastern time in the form of a net. They basically copied Japanese communications on c.w. 

I had occasion to learn this code because of some ham band intruders so used to join the group and found it very interesting.  I had many memorable communications with David "Poco" White who was a U.S.Navy historian from Cherryfield Me. He is now a Silent Key. We collaborated in recording and translating many incidents of "fishing reports" that were passed on the ham bands under the guise that they wouldn't be recognized for what they were. This transpired from 1979 to 1983. 

FRUPACers as they call themselves enjoy receiving a paper called "Cryptolog" which details many of their exploits during WWII  and the copies I obtained provide much interesting reading, such as the demise of General Yamamoto whose radio signals had been intercepted and resulted in his aircraft being shot down. 

References to Cryptolog can probably be found with Google.
