Mine was produced in July 88 and Dave's in Aug 88. There must be more to their coding as just subtracting the numbers is unreasonable. Maybe it is 1500 - 1000 = 500 produced between July and Sept with the last two digits meaning something else?? >>Larry Brown wrote: >>It looks like the first QST add for the FT-736R occurred in the October 1987 issue. Does anyone have a serial number beginning with 7? What did they do when they got into the 90's? I apologize for the bandwidth this may stir up, but life is slow! Maybe it will even help someone though. ron, w8gus.
