RE: [Repeater-Builder] voting receivers
Jed, The receivers are probable AstroTac receivers. Same as the Quantar, just packaged a little different. The receiver is just what you think. A receiver on the same RX frequency. The unit has a 2 wire and 4 wire output, but only uses the 2 wire for most applications. The unit puts out a tone when in non receive mode, this is called the guard tone. This guard tone goes away when a valid receive signal is received. The received signals audio is then sent out this 2 wire circuit. This circuit takes the received audio from the receiver to the voter and can be many different types, but normally is a phone circuit. The signals come in the voter thru the SQM modules, one for each receiver. This SQM module detects the guard tone and mutes the output to the voter command module. When the guard tone is absent the SQM module measures the signal to noise ratio of the received signal. If more than one signal is being received by the voter the command module picks the best signal and routes it to the output circuit of the voter. The command module is the brains to the unit. The simple explanation. I hope this helps. If you have any more question don't wait to ask. There are many on this list that can help.

RE: [Repeater-Builder] voting receivers
Jed: I have worked on voting systems from as little as 2 receivers to as many as 36 receivers in a public safety system. The best routing of the voted audio is by fiber optic cable, then microwave, then RF point to point link and lastly and the cheapest by telephone line. If you are using telephone line, be sure all lines are close together in frequency response and time delay characteristics. If not request the telephone company condition the circuits to be close as possible. Also, the newer voters have automatic line leveling circuits built in. These typically work by using the 1950 Hz no signal tone as a reference.

Re: [Repeater-Builder] MOVs for power supply primary
It's an Onan 4CCK-3R/1J 1800 RPM, 10 HP, 2 cylinder, gasoline, 3.5 KW, 4 KW surge, from 1965 with 57 hours use on it. In the 2003 Northeast USA power blackout, it ran two homes, including two refrigerators and a freezer. Perhaps not a home-size unit, but the advantage is that is sips gasoline at a low rate. After three days of the 2003 power failure, we had used up the stored gasoline and I was beginning to siphon fuel from the vehicles, as no gas stations were operational. My Comcast broadband Internet was gone after the first hour and my dialup IP answered and connected, but nothing past their site. I had just removed my Direc satellite Internet service two months before. Since Comcast cable TV wasn't there, I connected an outside antenna and was able to get the Detroit TV stations 50 miles away. It was nice to be able to see the stars again, without all the light pollution. My Astron VS-50M has a 10 Ampere fuse in it, but apparently there wasn't enough remaining current available from the generator to open it. I added the GE 130 Volt MOV (from Newark) to the Astron myself. I took my MOV out and everything works fine. My first impulse was that there was a problem with the generator, until I isolated the symptom to that Astron and I realized that plus 10% voltage was tripping my MOV. Ray Brown wrote: - Original Message - From: AA8K73 GMail aa8...@gmail.com mailto:aa8k73%40gmail.com I added a 130 Volt MOV across the hot and neutral of an Astron 50 Amp power supply for a repeater and had an interesting effect. We lost AC power and switched over to the generator. When the load was added to the generator, the Onan's voltage sagged a bit and the throttle opened to bring the speed back. It overshot slightly and was high enough to trip the MOV. That short slowed the generator down until the voltage was too low and then the generator sped up again. And again it fired the MOV and slowed down until it cleared. It kept oscillating with huge voltage swings until I unplugged the Astron power supply. That's very interesting, all right. Was this a single-cylinder 3600 RPM generator, or was it one of the twin-cylinder motor-home generators? I used to work for an Onan distributorship back when (70's) and we had a similar problem with a Southwestern Bell setup. They had a 2.5 LK, which was a single cylinder genset that ran at 1800 RPM. They switched a 500 watt load in and out several times a minute. When the 500 W load hit, it did the same thing you had described. I brought up a 1 KW load (heater elements) and plugged them in the circuit full-time, and it worked like a champ, going between about 40% and 60% of full load. Pretty stable. :-) Ray, KB0STN Yahoo!

[Repeater-Builder] Re: MOVs for power supply primary
Some things to think about. The rated operating voltage of the MOV needs to be greater than the PEAK AC voltage, not the RMS. During an over voltage event (spike or otherwise) the MOV conducts, generating heat. The higher the heat the lower the resistance causing them to go into thermal runaway quickly! This may result in a fire if the circuit is not properly protected by a thermal cutout. All recently UL listed surge protection devices (SPDs) are required to have a thermal cutout next to the MOV to disconnect power in the event of thermal runaway. I have seen many instances where an MOV has been installed without the thermal cutout and the result has been a fire. Many MOV devices will go into thermal runaway before they draw enough current to open a fuse of 10 or 15 Amps, typical of some of the larger power supplies. It only takes a small amount of current to cause thermal runaway where the MOV starts to flame and maybe cause damage to other items or cause a fire if not well contained in a non flammable compartment. As pointed out, the MOV degrades with every over voltage spike. Depending on the electrical environment, their effectiveness may be short lived. The best protection is achieved with a properly coordinated SAD (silicon avalanche diode) and MOV combination. UL1449, Edition 3 is an excellent reference. I would recommend that any surge protection device installed be UL1449, Edition 3, listed to ensure it does not cause a fire. I am referencing commercial devices, not individual components we may install in a project of our own as the individual components are typically not UL listed, only a complete product. When reviewing a product for purchase ensure that it has the UL1449 Ed 3 listing. Not just a UL seal as that could mean anything. Many protected outlet strips have a UL seal affixed but that only applies to the outlet strip portion being UL listed and not the surge protection portion. Generally if the manufacturer has a UL listing for the device as a surge protection device (SPD also previously known as TVSS devices) they will be proud of their UL listing and will have it printed on the label. Be sure you see Ed 3 appended to the UL1449 as the original 1449 of a few years ago did not require the thermal cutout device. Only after several fires was the standard changed to require the thermal cutout on the MOV (actually physically next to and electrically in series with the MOV) With respect to the generator surges Just from reading the post, my thought is that the only load on the generator was the power supply or maybe with an additional small resistive load. I suspect this was a switched power supply without power factor correction. I also suspect that the generator governor was not designed with a tolerance suitable for powering sensitive electronic loads and that there was no voltage and little speed regulation built in. AC power generators like a power factor of nearly 1. Therefore, we must ensure that a goodly portion of the generator load is resistive or has a PF of nearly 1. Many switched supplies have a PF of as low as 0.7. Without an appropriate resistive load to offset this low PF and help get this closer to a PF of 1, the generator may do strange things. Also, generators may exhibit strange operating characteristics when used with power supplies that have PF correction circuits built in. The wrong combination of load and generator may cause damage to the load (power supply). Products designed for international distribution have power factor correction circuits installed, such as several Motorola products. Be cautious when powering these products from small generators that you may typically purchase at your local home center. Those generators are not designed to power sensitive electronic equipment and may cause damage to the equipment. I have seen that happen all too often. Don't try a Motorola Quantar on one of these generators. You may be disappointed. A generator suitable for powering your sensitive electronic loads must have suitable speed (frequency) and voltage regulation built into the product. A reminder to evaluate your field day generator with respect to your load. I have heard stories where folks have brought their valued home station to a field day site only to take the power supply home damaged. I hope this is helpful. 73 Bruce, W3YVV
RE: [Repeater-Builder] MOVs for power supply primary
Probably the ones I've had the most luck with are the Islatrol series from Control Concepts. I think they have been bought out by Emerson or Liebert or one of the other companies that have power divisions. Anyway, they call these active tracking filters. They not only are TVSS's but also filter noise, low-amplitude spikes, etc. Right now I'm typing from a mountaintop site (broadcast) that we re-built a few years ago. We put in an Islator I-2100 (120/240V single-phase). The old equipment shelter which had been here since 1990 had the same model unit. In the 15+ years we've been managing and maintaining the site, we've had zero surge-related failures, and this site sticks out like a sore thumb as far as lightning goes. In the last few years I've used the same series of arrestors for new site builds at a dozen sites or so and have had no power-related problems. Others that make comparable-quality products include Joslyn, Transtector, and Innovative Technologies. There is one big difference (to me anyway) between TVSS's, that being whether they are the series or parallel type. Series type takes the utility service (or transfer switch output if there's a generator too) as its input, and provides a protected output to feed the panel(s). Parallel type is typically connected to a breaker in the panel, which puts it in parallel with all of the loads. I much prefer series. Parallel type can be less effective because a) there will always be some inductance and resistance in the wiring between the panel and the protector, b) if the TVSS conducts, there's a good chance it will trip the breaker in the panel, resulting in no protection until the breaker is reset, and c) they are much less effective as a noise filter. The upside to parallel type is they can easily be added at any time just by popping breakers in the panel and feeding the arrestor. Series, on the other hand, are in-line with the service conductors, so if you want to add one (or repair one), you have to take the service down. Series tends to also be more expensive, especially for three-phase and unlike parallel type, the price goes up as the current rating goes up for obvious reasons. A good 200A single-phase arrestor of the ilk I'm talking about starts at about $1000 and goes up quite a ways from there. I think these single-phase I-2100's were in the $2000 range. I recently spec'ed a 120/208 3-phase Transtector (parallel type) for another site where I'm much less concerned about power-wise, and that was about $1800. No cheap, but where you're protecting equipment in the 6 and 7 figure range, it's a no-brainer.

Bill I realize I replied to the wrong message and now I am replying to myself, so I am sure, I am confused by now. (-: I intended to reply to Mike's message, but I am sure Mike will reply, when he see it anyhow, so I won't repost and waste anymore precious bandwidth.. 73 John.
