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.

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.

[Repeater-Builder] detuned duplexer cause intermod?
Pretty sure I know the answer to this. But can a transmitter keying into a duplexer that's detuned cause intermod interference? I have a transmitter that I turned down the power because it had desense on it. Turning the power down fixed the desense but now I am wondering since its still transmitting into a poor load, can't that cause some intermod interference to other repeaters? It's a tband repeater. Can that cause problems all the way to vhf? I haven't tried retuning the duplexer because one, it has not been touched in 20 years and two, the shafts are rusty. We are currently planning on replacing the repeater but it could take up to another year and I don't want to cause interference to anyone during that time. -Tim Yahoo!

I used no duplexers or filters and have excellent results. Running at 70 watts with DB 212 folded dipoles for TX and RX.

Clean them off with a brass or stainless steel brush. Don't use plain steel brushes. Lightly lube the cleaned shafts with a synthetic spray like Amsoil MP Spray or Dupont Teflon. Use a small drill motor to run the shafts in and out at least 75% of their normal travel. Then retune them to the desired operating frequencies. The hope is that running the shafts in and out might remove any basic oxidation on the internal plunger and the internal finger-stock will sort of polish-off or clean any pitting on the tunning plunger.

[Repeater-Builder] Re: Kinda of a strange question
You beat me by a couple of years. I built a 22S control system from TTL that was on Palos Verdes and then later on Onyx Peak (9114 feet). The original controller used octal to set the actual N code into the 22S, but I later added a 2708 lookup table. *52 put you on 146.52, *34 put you on 146.34/146.94. Since it was all done by a lookup table it knew the band plan and would automatically select a repeater split if you dialed an input frequency or simplex on the output if you dialed an output frequency, etc. It did the right thing if you dialed *40 (people from L.A. will know that frequency). There were commands to force simplex or reverse. I can't find the schematic any longer, but I did find a control list dated 12/79 that was after the lookup table was added. My best guess is 1/79 when it first went on the air. I know my controller wasn't the first 22S controller as I later compared nodes with Greg (WB6KCD ?) who that had built a controller before I had. It also had cw unkey telemetry that sent the frequency in cw when you unkeyed. I can't tell you how sick I got of hearing 46 and 52 in cw over and over and ... It sounded like a good idea at the time. Boy those were the days ... we had the only ham box on Onyx peak for a year or so and could hear 3 states ... then a 2 meter repeater was installed.

[Repeater-Builder] New Sinclair 2M Antenna Question
We just purchased a new Sinclair 2-Meter Collinear antenna for our 2-Meter Repeater to replace a similar Celwave Stationmaster antenna that was about 14 years old (turns out we probably really didn't need to, it still looks almost brand new). The new Sinclair 2-Meter antenna arrived (ordered for our 2-Meter channel) and we found a second cable going into the base of the antenna. There's the main antenna connector, and there's also a short length of what appears to be RG-142 cable, hanging out and going nowhere. We've worked with many of these Stationmaster type collinear antennas for many years, but have never seen anything like this. The instruction sheet and frequency sweep don't mention anything about this loose cable going into the antenna. Has anyone else seen this and know what it's for? Our dealer that we ordered it through hasn't seen anything like this, either, and was at a loss to explain what it might be. We also ordered a brand new 10dB Sinclair collinear for 440 MHz, and it doesn't have this extra cable. LJ mail2web - Check your email from the web at http://mail2web.com/ . Yahoo!

For several years I had my UHF 6 meter repeaters at the same location, the antennas about 10 feet apart. They were both tied into the same repeater controller so you could go in on either went out on both. The ERP of the UHF was about 160 watts, the ERP of the 6 meter was about 80 watts. Both were GE Mastr Pro repeaters. Like stated below, there were places the UHF covered better there were places the 6 meter covered better. 6 meters was better behind hills or in valleys. -- Original Message -- Received: Sat, 18 Sep 2004 05:19:00 PM CDT From: W9DHI [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] low band repeater I currently have a 6 meter repeater on the air, we also have a 10 meter but it's not currently up. The 10 meter was split site using a UHF link but the 6 meter we have up is using duplexors. It is a MastrII and works very well with a 1 meg split (53.03 out, 52.03 in), we modified a 46 meg loop antenna (DB products) and built a new phasing harness and it works very nice. It's about 180' up the tower face of a 260' tower so we do have some pattern distortion as the antennas are leg mounted. At the same site we have 444.850/449.850 running a 1/4 K and the that antenna is top mounted. The coverage is a little better on 440 without any pattern distortion, but otherwise the coverage is equal. However in low spots where there is shading and the UHF doesn't work, the Lowband does and there are situations that are the complete opposite where the UHF works and the VHF doesn't .

[Repeater-Builder] ACC850 VS RLC1Plus Controller
Hello: Wondering which controller is the better controller for use on a Yaesu Vertex VXR-5000 UHF Repeater. I have both controllers but have no idea as to which one would be the better controller to use with the Yaesu. Wondering if anyone have interfaced either one of the controllers with the Yaesu Vertex VXR-500. Any information would be helpful. Thanks Yahoo!

[Repeater-Builder] Motorola GM300
Greetings, Does anyone have any experience using the Motorola GM300 radios as crossband link transceivers? I have successfully reprogrammed the UHF transceiver for 434 MHz. use. All appears to work well. I understand that I can mate this to a VHF version (reprogrammed for our 2 meter input frequency) and the two will successfully crossband. I realize I have to make up the cable to connect them. I'm looking for feedback from someone who has done this. Pros? Cons? Suggestions? I see there is a squelch modification that is recommended which I will do. Anyone have a scanned service manual? I have the schematic but would like a board shot so I can identify specific parts from the schematic. Any recomendations will be welcome. 73, Scott Madison, WN1B Yahoo!

Use a small drill motor to run the shafts in and out at least 75% of their normal travel. Then retune them to the desired operating frequencies.

The picture on the spectrum analyzer looked like a Christmas tree as the PA was going into all kinds of spurious oscillations.

Call 440.05 448.05 W6BGM 440.55 448.55 K6VPE 440.65 448.65 K6DGX 440.85 447.94 K6QEB 440.95 448.75 WA6ESC 441.10 448.94 WA6ESC 441.25 449.25 WB6DOW 441.45 449.50 WA6HTP 441.93 449.73 K6AHF 442.00 449.60 K6RGW 441.85? 449.83 W6YDZ 442.63 449.63 WB6GUA Several of the above call sign holders have passed on, a few more are still around - somewhere - also using different calls. Frequency coordination in those days was more a matter of someone knowing who was where ... so you didn't accidentally order crystals for your RCA CMU15 or GE MC306 on a frequency already in use. It wasn't always a problem as sometimes the tweaking capacitors could move that crystal to the next channel. Hope the above gives you a smile ...

My memory isn't that great, but I remember a Ken that lived on a house boat in San Pedro, was that you? What was your call in the good old days? What was the remote call? That'll probably jog the memory record from off line storage ! ---Yep, that was me. My old call was WA6EMV (oh no, not him!!). Back in those days, I was the typical know-it-all kid, as opposed to now being a snotty know-it-all middle aged guy! My old system was originally WR6AKB and then (of course), it became WA6EMV. We were one of the very first to be coordinated on a VHF splinter channel in SoCal - 146.745/.145, which is where we ended up after first being coordinated on 147.69/.39, which caused the conflict with the GR0NK guys. Man, I remember them programming up a CW IDer that sent the following as part of our war: - . . . - - . - . -. - . - - . . . - . . (the above is exactly what their ID sent. If you look at it in a mirror, it would say F*** EMV. I always thought that was very clever on their part! :-) I finally had enough of 2 meter repeaters and moved to UHF (443.325 I *think*) and have stayed on UHF ever since. Anyway, there's the sordid story!

Tim S. [EMAIL PROTECTED] wrote: Pretty sure I know the answer to this. But can a transmitter keying into a duplexer that's detuned cause intermod interference? It sure can. A local area repeater in Michigan on 146.64/04 was causing interference, and was being heard, on a 146.68/08 repeater about 60 miles away. Someone, un-authorized, had made adjustments to the duplexer (Tx out into duplexer 40 W, power out of duplexer 3 Watt). The picture on the spectrum analyzer looked like a Christmas tree as the PA was going into all kinds of spurious oscillations. After retuning with proper equipment (vector network analyzer) all interference stopped and the TX was clean again. An isolator will do the trick to protect the PA and reduce the chance of spurious oscillation and inter-modulation but it will not cure the problem. Retune the duplexer ASAP with proper equipment. 73, Tony VE3DWI --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

[Repeater-Builder] Re: Motorola GM300
Sorry about posting an inquiry on a previously covered topic. I had done a search on GM300 and come up dry. Can't explain it, but it happened. I have read all the posts from last months inquiries. There is a lot of good information there. I'm still interested in anyone's comments, though. You can e-mail them directly to me rather than take up bandwidth here. 73, Scott Madison, WN1B --- In Repeater-Builder@yahoogroups.com, wn1b8 [EMAIL PROTECTED] wrote: Greetings, Does anyone have any experience using the Motorola GM300 radios as crossband link transceivers? I have successfully reprogrammed the UHF transceiver for 434 MHz. use. All appears to work well. I understand that I can mate this to a VHF version (reprogrammed for our 2 meter input frequency) and the two will successfully crossband. I realize I have to make up the cable to connect them. I'm looking for feedback from someone who has done this. Pros? Cons? Suggestions? I see there is a squelch modification that is recommended which I will do. Anyone have a scanned service manual? I have the schematic but would like a board shot so I can identify specific parts from the schematic. Any recomendations will be welcome. 73, Scott Madison, WN1B Yahoo!

Re: [Repeater-Builder] low band repeater
Yup, that is typical of low-band radio. Neil - WA6KLA JOHN MACKEY wrote: For several years I had my UHF 6 meter repeaters at the same location, the antennas about 10 feet apart. They were both tied into the same repeater controller so you could go in on either went out on both. The ERP of the UHF was about 160 watts, the ERP of the 6 meter was about 80 watts. Both were GE Mastr Pro repeaters. Like stated below, there were places the UHF covered better there were places the 6 meter covered better. 6 meters was better behind hills or in valleys. -- Original Message -- Received: Sat, 18 Sep 2004 05:19:00 PM CDT From: W9DHI [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] low band repeater I currently have a 6 meter repeater on the air, we also have a 10 meter but it's not currently up. The 10 meter was split site using a UHF link but the 6 meter we have up is using duplexors. It is a MastrII and works very well with a 1 meg split (53.03 out, 52.03 in), we modified a 46 meg loop antenna (DB products) and built a new phasing harness and it works very nice. It's about 180' up the tower face of a 260' tower so we do have some pattern distortion as the antennas are leg mounted. At the same site we have 444.850/449.850 running a 1/4 K and the that antenna is top mounted. The coverage is a little better on 440 without any pattern distortion, but otherwise the coverage is equal. However in low spots where there is shading and the UHF doesn't work, the Lowband does and there are situations that are the complete opposite where the UHF works and the VHF doesn't .

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