Steve WA6ZFT Years ago a group here in L.A. did the RD and actually breadboarded the hardware and had a couple of exciters running. The impetus was finding 25 Panasonic color TVs that ran on +12v (made for RVs) in the city dump that has smashed picture tubes. They added a PLL to determine if the TV's color burst oscillator was locked to the off-the air signal. This lock signal was used to select F1 vs F2 on the exciter. F1 had a regular channel element, F2 had the output of the synthesizer. The synthesizer was designed around using the TV color burst crystal as it's reference oscillator, and output a sine wave signal into a channel element that was modified to be a simple signal buffer (hint: the hole in the element cover fits one manufacturer's SMA connector just fine). The system never got built - the group was getting free rent at six prime privately owned sites (in exchange for site management and maintenance duties) and the owner sold out while the selling was good, and the sites went from zero to $250 a month. I have no info on the hardware design, the engineer that was doing the work died from emphysema a while back his smoking caught up with him. Mike WA6ILQ Yahoo!

Re: [Repeater-Builder] Micor mobile repeater - no audio?

Power it off, remove all the screws that mount the boards that plug into the center board, and unplug them halfway, then plug them back in several times i.e. stroke the male pins in and out of the female connectors (and get your mind out of the gutter). I've seen several Micors develop weird problems that were temporarily fixed that way. The fix lasts 6 months to a year, and I've yet to come up with a cure other than soldering them all, which - while the problem is fixed - makes the radio unrepairable in the future.

Waveguide modes are set up when the internal lateral dimensions of the coax approach a half-wave at the operating frequency. These modes can destructively cancel causing very high losses. In building a Ku-band satellite uplink, I once had a technician puzzling over why his RG-213 jumper wouldn't pass 12 GHz.

Re: [Repeater-Builder] Crimp Tool
Ed, Amphenol, AMP, and RF Industries make good-quality crimp handles and dies. The dies you need depend on the cable size as well as the connector. Generally, 0.068, 0.100, and 0.128 dies cover most contact pins, while 0.213 and 0.429 dies cover most ferrules. If you do a lot of connector crimping, it may be worthwhile to buy a kit with two handles, since all of the above crimp sizes are satisfied with two sets of dies. TESSCO sells handles, dies, and kits. 73, Eric Lemmon WB6FLY va6ef wrote: Hello Everyone I am in need of a crimp tool for uhf and n connectors; anyone point me in the right direction for aquiring one or have one they want to sell contact me off list if you do thanks Ed VA6EF Yahoo!

Re: [Repeater-Builder] Simulcast: Anyone done this for ham repeaters
There is tons of equipment out there from the old analog paging days that can work on the 440 ham band and is simulcast capable. I worked on a 931Mhz Glenayre system ears ago that was capable of analog voice simulcast and it worked well. A great simulcast 440 ham system could be put together if you could find this old paging equipment. Making all the transmitters simulcast would not be a real difficult job, but your limitations would be receiver sites. It would not be difficult to do a simulcast system with a single receiver, but would be very complicated using multiple receivers. 1) Keeping all the transmitters frequency stable could be done with a TXCO. Routine maintenance would be required, let's say twice a year, to adjust the frequency. Interestingly, you would NOT adjust them all to be exactly the same frequency! You would offset them, maybe 20-30HZ, instead of putting them all on the exact frequency. This is known as frequency offset the paging industry. This reduces deep phasing nulls in the overlap areas. It does cause a 20-30HZ tone on the signal, but the average transceiver will not pass this audio frequency. 2) You need some sort of audio delay circuit to adjust the multiple transmitters launch time. For example, two transmitters are adjusted so that the audio out of both transmitters leave at precisely the same instant. Then, the signals that the mobile receiver hears will add to each other. Analog voice paging stations have circuitry to create this delay. 3) Flat audio should be used in all the links and transmitters. The audio should only be preemphasized once in the system so that the transmitters all have the same audio characteristics. To keep things simple, all receiving and transmitting equipment should be the same manufacturer and model. 4) Deviation needs to be tightly controlled in all the system. 5) The list goes on and on. Purchasing an old voice analog paging system in the 450Mhz band, along with all the linking radios, would simplify the project. The major problem I see is: How many receivers are you going to have? If it is more than one, you will have to backhaul all the receiver audio to a central location, select the active receiver, and send it back out to the transmitters. - Steve Rodgers [EMAIL PROTECTED] wrote: Has anyone implemented a simulcast (multiple TX's on the same channel) system for a ham 440 repeater system?

I picked up a UHF HiPro years ago and was not impressed at first. Now, after having it on the air and connected to a antenna 450 up at the top of a tower I am impressed. The little thing has been working perfectly for several years. It is also easier to service, not surface mount technology, if repairs ever had to be made. The HiPro is much better quality than Hamtronics, I had a hamtronics on 222Mhz. I believe that the circuit board and component quality is better in the HiPro. BTW, my Hamtronics was and older version, I can't speak for the new Hamtronics stuff. I don't know about Kenwood, never had one.

Then once you hear the activity, get the callsings of those using thre frequency.

The scanner recorder program they mentioned works great. If you not very far from where your repeater will be, at home listening will be fine. Once you have listened for a few weeks, then give your results to the IRC and they they will submit to the surrounding states and see if any of them oppose the pair they have given you. Hence warning, check the next pair above and below your given frequency within at least a 75 mile radius, if users use your system and they are beyond that point, they may cause intereference and it would cause you to be come uncoordinated.

The computer appears to be ok, but will not report the program storage module as a peripheral. It will report the printer, the EPROM burner pads and the ram of the computer. The program storage module has one program installed for the Phoenix. I have tried cleaning the contacts, placing the module in a different location, and staying at a Holiday Inn Express, but nothing so far. I suppose it is something in one of the chips.

RE: [Repeater-Builder] Cushman Service Monitors: Who Repairs Them
You may want to check with NS Electronics in Atlanta Georgia I believe, the last guy I talked to was a guy named Paul. NS is actually the closest descendant company from the old Cushman company, it used to be KNS. The "K" stood for Ron Kelly, one of the main engineers with the original Cushman. Ron and the "NS" in the company name bought the rights ,if any, to the Cushman name when the original owners decided to only build some sort of cell phone monitoring device for the government that did not work or sell very well.

[Repeater-Builder] Micor Mobile Repeater - No Audio?
Many years ago, my friend W8ICN told me of a cure for the invisible corrosion on Micor pins that they had developed at Detroit Edison. I couldn't remember what it was, so I dropped him an email about it. Here is his reply. Dan Hancock N8DJP We used a mixture of Squibb mineral oil and isopropol alcohol, about a 1:3 ratio, 1 part mineral oil and 3 parts alcohol. With the boards unplugged, coat the pins and sockets using a small artist brush. The alcohol evaporates quickly leaving a fine coat of oil on the pins which inhibits corrosion. Works well. Do not scrape the pins otherwise you will be removing the plating causing even bigger problems. Of course if the pins are corroded to start with, gently clean off the gunk before applying the oil and alcohol.DanDaniel Hancock wrote: Read the messages below.

RE: [Repeater-Builder] Simulcast: Anyone done this for ham repeaters
John and Group, While in the paging industry we had a high band, UHF and 900 MHz paging systems. We ran analog on some and always the highest speed digital paging available. All we had for a time base was the old Ovenaire high stab oscillator until some time later. As a rule we netted the transmitters once every 6 months which seemed to be good enough for high band, UHF would be a little worse unless you used a higher stab oscillator. By all means GPS would be much better but as you said it's all about resources. ISC in Quincy Ill. would probably have all you need of the older technology stuff to build something like the system you spoke of, again all it takes is money. GPS would be much higher cost.

Many years ago, my friend W8ICN told me of a cure for the invisible corrosion on Micor pins that they had developed at Detroit Edison. I couldn't remember what it was, so I dropped him an email about it. Here is his reply. Dan Hancock N8DJP We used a mixture of Squibb mineral oil and isopropol alcohol, about a 1:3 ratio, 1 part mineral oil and 3 parts alcohol. With the boards unplugged, coat the pins and sockets using a small artist brush. The alcohol evaporates quickly leaving a fine coat of oil on the pins which inhibits corrosion. Works well. Do not scrape the pins otherwise you will be removing the plating causing even bigger problems. Of course if the pins are corroded to start with, gently clean off the gunk before applying the oil and alcohol.DanDaniel Hancock wrote: Read the messages below.

Re: [Repeater-Builder] HJ9-50 loss
Well, the specs for LMR400 (same frequency - same length) is 0.388 dB and 9913 is .421 dB. RG-6 would be 0.932 dB. So, if 0.34 is too much, the others you mentioned would be no solution. Joe M.

Re: [Repeater-Builder] PARTS
Bob, You are just starting and finding that it is getting very hard to find parts to build anything. There are a lot of fun things to build and can be very educating at the same time. I have built a lot of radios when Heath Kits were around. I have also built some the kits you can find on the internet. I have over 200 different electronics things that I have built and learned from. Most of the kits had all the parts in them, some I had to look for. That is not the case now, and it does not look like it is going to get any better. I have 1 project that I have started, and had to go to 28 different suppliers to get the parts. I have 3 more parts to locate and then I can start. The biggest problem is finding some of the parts that are called for in the project list. They may show a supplier, but when you start looking the supplier is gone, moved, or no longer has that part. Finding a substitute that will work is getting hard as well. On the last project that I completed I had to order a crystal that took 3 months for them to make. They had to grow that type before they could make it. The cost was a little high, $150.00, but it was worth it. The radio sound just like it did when it was made in the early 40's. Nicely restored with original parts, no replacement or substitutes. I sold the radio for $1,500.00 as a restored piece and made a few bucks to boot. I have found that the local TV repair shop is a very good source if you have any in your area. They have to have been in business before the 80's or you will get a technician that is to new and does not know what you are looking for unless he worked for one of the older shops.

RE: [Repeater-Builder] Simulcast: Anyone done this for ham repeaters
I posted the following message once before when simulcast transmitters were being discussed but I don't think it made it to the list: I've taken cell-site-surplus rubidium oscillators with 10 MHz outputs and used them as the reference for GE Delta-S synthesized radios. If memory serves the stock reference oscillator in the Delta-S VHF and UHF is 13.2 MHz. I made some firmware changes so that I could just program the radio normally after hooking up the 10 MHz reference in its place. The UHSO oscillators out of Micor/Purc stations are OK, but require more frequent adjustment as they age, and of course, you need test equipment that is high-stability as well. I have one of the rubidium oscillators on my bench that all of my test equipment is locked to, and I verify the frequency periodically with a GPS timebase just to make sure the rubidium hasn't drifted. Although I don't know what the specs are for the rubidiums I have (all of which are made by Ball/Efratom), carrier frequencies (as measured at UHF) have never differed by more than 0.1 Hz. If you're at a site with GPS-disciplined equipment already there (modern simulcast paging transmitters, HD/IBOC FM transmitters, etc.), you might be able to convince the owners to give you a split off their 10 MHz reference to save on the cost of having to come up with your own. I have three repeater transmitters running with the rubidium/Delta combination, but I haven't tackled the audio delay issue yet. The rubidium/Delta marriage and on-air testing has been more or less just a proof-of-concept excercise up to this point. When I have more time I'll get back to the project. --- Jeff Jeff DePolo WN3A - [EMAIL PROTECTED] Broadcast and Communications Consultant -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of JOHN MACKEY Sent: Sunday, June 05, 2005 7:37 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Simulcast: Anyone done this for ham repeaters That's just it, resources!!

I have built some parts bins out of cardboard boxes and some wooden crates but can't find any parts except in TV's and old radios. Some are usable but I don't have a reference for most of them to see what the specs on them are. Something that would have assorted parts including perf boards, small enclosures, ect We live in the country and the closest parts store is over 100 miles away so we wanted to find it on the internet and hopefully at discounted prices the XYL says, no more than $50.00 TNX, KE5CTY (old calls WB5ZQU - WY5L) http://www.qsl.net/ke5cty/ Code may be dieing but the pioneering spirit that put the code there in the first place is still going strong. __ Discover Yahoo!

[Repeater-Builder] Mastr@ Base 2 mtr pwr amp failure need help
Local 2 mtr repeater using MastrII Base repeater station experiencing power amp failure. Circuit board 19D424266G1 Rev3. I do not have manual. Am told its a 100 watt unit. It does not have the 4 parallel output transistors in PA section. Symptoms are: turn up power controlto 90 watts and ok until you drop input, rekey and it will not produce output power. Crank power pot back down, turn it up to 90 watts again and it will run 90 watts all day until you unkey driver again. (using .5 watt HT for testing). Unit had the typical circuit board break on output pin to filter board. Repaired same. Unit also pulses rf power badly and can see amplitude pulse on analyzer. No spurs on sidebands. If anyone cares to comment I would appreciate it. Thanks, Gary K2UQ Yahoo!

Re: [Repeater-Builder] GE suitcase programmer TQ2310
You need to go in the setup program on the panasonic computer and turn on port for the memory location. Its in the book on how to do it. Yahoo!

Gary, The 19D424266G1 PA is a 110 watt board that uses two high-power transistors in parallel. Here's the manual: http://www.repeater-builder.com/ge/lbi-library/lbi-30739j.pdf 73, Eric Lemmon WB6FLY [EMAIL PROTECTED] wrote: Local 2 mtr repeater using MastrII Base repeater station experiencing power amp failure.
