Re: [Repeater-Builder] Kinda of a strange question
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.

Very cool, Michael.

RE: [Repeater-Builder] Kinda of a strange question
I remember using a 2M synthesized remote base in Las Vegas back in 1975. They used a VHF Engineering synthesizer - not a GLB (but I don't remember what kind of VHF radio it was hooked up to.) Buried somewhere, I think I still have the schematics of the system's controller, etc. LJ Original Message: - From: Ken Arck [EMAIL PROTECTED] Date: Sun, 19 Sep 2004 16:50:29 -0700 To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Kinda of a strange question Hi folks Is anyone aware of the earliest use of a synthesized remote base on an amateur repeater?

Re: [Repeater-Builder] Kinda of a strange question
Ken: Thank you for your e-mail. Well, I wish that I could say that I did it, but it was my friend, K5HMD, who had moved to Oklahoma from Dayton, Ohio. I recall that I helped him with the boards and the space on the building and other small things. He designed and built it. He is now living in Texas and I will send him an e-mail to ask him if he remembers when he did this. Speaking of card cages, about this time I collected some designs and laid out a four board TT decoder which used an AGC and bandsplitter prefilter, eight 567's, eight NE555's wired as missing pulse detectors, and the logic for 1 of 16 output. It worked fairly well, but the 567's had to be touched up from winter to summer and vice versa. I also laid out the K2OAW ider and three other cards that had a simple squelch tail and time out time (from 73 Magazine), a power supply, controller, and timer for the ider that we designed, and a latch board that had two D flip-flops for controlling the repeater. I originally used 6 x 3 cards for this, although I later laid other cards using 22 pin edge connectors on plug-in boards that were 4 1/2 x 6 1/2 in size. This included a Mostek 5103 TT decoder with an AMI S3525 digital prefilter. I also laid out a Micor squelch card which could take discriminator audio and had all the adjustments and logic for a repeater and included an LM386. Some friends of mine revised the circuit board and this card is still being used today on the repeater. I will let you know if I get any more info.

Re: [Repeater-Builder] Kinda of a strange question
I don't think that the VHF Engineering synthesizer was out in 1975. I had a GLIB around 1979 and don't recall that VHF Engineering had introduced their synthesized unit yet.

At 09:51 PM 9/19/2004 -0400, you wrote: That would have been using a GLB synthesizer? ---A Vanguard, actually. And a Metrum II (remember those?). As did Mike, we designed a complete TTL controller (5 x 7 cards in a cage - state-of-the-art!), using 567 decoders that did all the usual controller functions. And of course, it controlled the Vanguard as well. While we could directly enter frequencies, we also had memories that were assigned by a diode matrix with dip switches to select the channel frequency. That system served us well until the early 80's, when I bought my first RC-850. I think I might still have the system schematics and drawings around here somewhere. By the way, this was in either 1975 or 76. And it was done in Southern California.
