In the FJ force only the F3 was to be modified
Yes, they led and we got on the back of their production contract. They had multiple failures which delayed acceptance, but they were in a part of the spec we didn't need, so a suffix was added to the part number for rotary. That radio had 12.5, 8.33, 5, 2 and 1kHz spacing. I'd say 1997, perhaps 1998, was the first time we had one working on the rig. I know I wrote the system specs in December 1994.
