Ken: About that same time a friend of mine in Norman, Oklahoma modified his UHF to VHF remote base to add a home built GLB synthesizer to his tube VHF remote. He built the logic for it and I think that he used a 567 tone decoder set. I remember this because it was after I got out of school in 1975. I think we later went together and bought a Telenetics (?) hybrid digital tone decoder and he built it onto a plug in board and substituted it for the 567's. It worked great and the remote base was a lot of fun to use.
In fact, somewhere I may still have an extra set of GLB boards and the assembly instructions. He stored the frequencies in registers to program the GLB. When he had it ready, we put it up on the same building as the club repeater on the Oklahoma University Campus for which I am the trustee. The remote used Ringo Rangers, not good antennas. We put it about 100 foot horizontally down the building to avoid desense from the 146.88 repeater, but there would still be some when the remote came up. He could bring up the receiver, change frequencies, then bring up the transmitter, and switch between hi and low power. Later he designed a board using 1702 eproms to use an IC-22s in a remote base. I laid out a PC board for him and made him several copies. Another very close friend of mine, K5JB, built one of the boards and used a KIM-1 (6502) microprocessor to control a 22s and make it scan. I may have the radio because he left me a bunch of his radio equipment when he passed away. In fact, I probably still have an EBKA Familarizor Single Board Computer which was very similiar to the KIM-1 which I got from the fellow who designed it and was an acquaintance of mine at the time. I could probably go back and try to get a closer date to when this was.
