Mathew You might be better off getting a commercial type exciter. The Micor mobile or base exciter puts out around .4 to .5 watts and might be a good choice to look at. They are widely available, and lots of literature about them. They also are continuous duty rated, and you can probably pick one up for under $20 (you can get the whole radio for that much).

Re: [Repeater-Builder] Duplexer cable question
Jed, Start by using as much cable as necessary to make the connection, then, and only if you have problems should you worry about cabling lengths between the duplexer and radio set. Use quality cable like RG-214 Mil Spec. BTW: If the length is dependent, there is no simple magical length formula, like 1/4 wave or odd multiples there of. Proper matching depends on the impedance presented by the radio set, duplexer, and to some degree, antenna. If the length is critical, you won't see the right output power at the antenna port of the duplexer. If your duplexer is a Wacom WP-652 four cavity model, the stated loss of the pass frequency is 1.2 dB, which translates to approximately 24% of your applied power will reach the antenna port. So, if you applied 50 watts to the transmitter port of the duplexer, and the duplexer lost the stated amount of 1.2 dB (24%), the power coming out of the duplexer should be about 38 watts. Wacom has a write up on optimizing duplexer interconnecting cable lengths: http://www.repeater-builder.com/pdf/wp6xxVHFtuninginstructions.pdf Page 4 of the document under the obvious heading. Jed Barton wrote: Hey guys. OK, I'm sure this has been discussed, but I figured I'd ask.

Easy answer, It is made from the same medal i.e.: copper braid (double braid) with silver coating on both. NO tin foil to rub on the brad and make it get crackle.

Do yourself a BIG favor and find a 25w UHF Micor mobile. It's rated for continuous duty and is EASY to convert. Likewise a low power Mastr-II. Or take a RCA 700 series UHF mobile radio.

Re: [Repeater-Builder] FCC Enforcment
The weather forecast should have been your first clue. Even though it doesn't say exactly where it is... it have a picture of the Sears Tower the station is in Chicago! Secondly, to answer the first persons issue about triangulation... that is what they were doing by driving around. They initially took a bearing, drove past it, took another bearing reading and then drove around again to grab another bearing and then nailed it. Which is entirely possible with what Hams have available to them except what Uncle Charles has is more computerized so a monkey can operate it. Example: A ham - one person, not a whole fox hunt team - can drive around, take a bearing with a yagi antenna, drive around some more and grab a bearing and then finally drive to another location to grab a bearing each time logging their GPS location where they took the reading ... whalla, plot your GPS locations and bearings onto a map and BAM! you have your triangulation with just using one tracker. This is the old skool method, unless you have big $$$ for a computerized GPS enhanced Doppler RDF system like the FCC. Its far Far FAR!!! more accurate than taking one directional reading and then accusing XYZ station for causing interference just because that station is within or close that path from where the reading was taken. I speak from experience since I have been the accused from a ego sensitive, never can be wrong, blame it on everyone else person in Hubertus, WI who will take a reading from his back yard and accuse anyone and everyone who is on his schnit list that day who just so happens to be within that RF path - of which his reading may be a wee bent or favored due to the alcohol and or drugs.

[Repeater-Builder] Re: Duplexer cable question
I agree with Kevin. We had to change out hundreds of LMR cables on a large commercial system because of noise and intermod being caused by the LMR connectors, and sometimes by the LMR cable moving on the tower. A few other points: 9913can distort the relationship of the inner conductor to the outer conductor when bent in a small radius. This can happen over time and change the impedance of the cable. LMR and 9913 have a very light braid covering on them. This braid then attaches to the connector to make the electrical connection. In my opinion, the foil does not make a good electrical connection to the connector, so you are depending on a limited amount of braid wires to make the connection. Flexing the cable can break the braid inside the connector. The amount of loss in a 2 foot jumper of good quality RG-214 is insignificant compared to LMR or 9913 cable. The superior connection that you can make soldering RG-214 to a connector probably more than makes up for the losses. A1 foot jumper of each type at 400Mhzwould be: 9913= .034dB RG-214= .041dB LMR-400= .025dB Using these figures, you would be saving about .016dB if you used LMR-400 insead of RG-214. This wouldhardly be worth the effort. If you really want to go all the way and "gold plate" your system, use hardline for the jumpers. My favorite cable is Andrew 1/2 inch superflex. It makes excellent mechanical connections, 100% shielding, it will bend to small radius, and is durable. Unfortunately, UHF connectors are hard to come by for this type of cable. Joe Cables that are made of tin braid over aluminum foil can suffer from dissimilar metal noise problems. Those types of cables should be avoided at a duplex site.Only quality silver plated double shielded cables should be used in duplex service. Kevin Custer Yahoo!

[Repeater-Builder] Re: Stuck Repeater
I would check your COS line voltage. My first repeater that I built had a similar problem. I was using a Hamtronics controller and a Midland receiver. The COS line voltage was running somewhere in the 1 volt range when the receiver was active. (Hard to remember specific voltages). Anyway, I was in a range of voltage that the controller was geting confused if it was suppose to key up the transmiter or not. Any change in temperature or voltage or noise on the line made it get stuck in the keyed mode. I fixed this by adding a coupe of transistors to pull the line closed to ground when the receiver was active and added a "pull up" resistor to pull the line closer to 12VDC when the reciever was idle. Instant reliability of the receiver! Different controllers mayneed different voltages to tell it if the input is acitve or idle. For example, my S-Comm controllers use 2.1VDC as the crossover point. You need to pull the COS line above or below this voltage to indicate active/idle COS. 73, Joe, K1ike Repeater-Builder@yahoogroups.com wrote: rtoplus wrote:Well I visited the site and powered down everything...let it all rest for about 5 minutes.

Re: [Repeater-Builder] Using an HT for a Transmitter -Thoughts Ideas
Hello Mathew, Knowing Regency, yes I was called upon to (attempt) to service one once, *almost* anything in GE, RCA or Motorola or even a Bendix mobile radio will be better. When I mention Bendix, they made a certain mobile radio that, it seemed, someone had borrowed (ok, swiped) ideas elsewhere. The tubed receiver almost looked like a Motorola Research Line receiver strip. The transmitter looked very similar to a GE Progress Line. (I think I remember the power supply as being a regurgitated form of an RCA?) You may not know it, these days, in the mobile radio world, only General Electric and Motorola seem to still stand out - at least in the United states. Over the years, there were a few others some of us would really rather try to forget. Even Motorola and General Electric had some clinkers that were ... well let's say, not the best in reliability or really serviceable. Each radio tech I have known over the years had his own less than favorable product he had a slightly different name for. ;) I will relate this one story ... a certain manufacturer made a UHF radio (the only one I ever saw was a base - but were made in a mobile package too.) The receiver ... took a 75 MHz range crystal tubed oscillator / tripler (one stage) fed that signal to the diode frequency doubler stage which was also the first mixer. One stage of RF amplification prior to the diode first mixer then into the IF amplifier chain. When everything was new, sensitivity was ... er, ah, well, ok at best ...

It's rated for continuous duty and is EASY to convert. Likewise a low power Mastr-II. Or take a RCA 700 series UHF mobile radio.

Re: [Repeater-Builder] Re: Duplexer cable question
Ok, couple of questions. Is RG400 a solid center conductor, or is it stranded. The Cable that I have here was supposed to be LMR400, but that is made by Times Microwave, and the cable that I used on the repeater is made by Ultralink, Cushcradt, Manchester NH. Does not really have any other figures on it. Also, if the shield is made of steel, and is not magnetic, then how would one get solder to stick to it. Or is this why some guys are going to the crimp on connectors? I have plenty of 1/2 superflex avaialable, but you are right, the connectors are hard to come by in UHF. Duplexers have type N, but it is easy to change the connector in the radio's to Type N. I also have a good amount of 3/8" hardline, FSJ something or other, Superflex cable, would that be as good as the RG-400? Thanks for the information. The help is more than appreciate. Mathew - Original Message - From: Joe To: Repeater-Builder@yahoogroups.com Sent: Friday, June 11, 2004 3:46 AM Subject: [Repeater-Builder] Re: Duplexer cable question I agree with Kevin. We had to change out hundreds of LMR cables on a large commercial system because of noise and intermod being caused by the LMR connectors, and sometimes by the LMR cable moving on the tower. A few other points: 9913can distort the relationship of the inner conductor to the outer conductor when bent in a small radius. This can happen over time and change the impedance of the cable. LMR and 9913 have a very light braid covering on them. This braid then attaches to the connector to make the electrical connection. In my opinion, the foil does not make a good electrical connection to the connector, so you are depending on a limited amount of braid wires to make the connection. Flexing the cable can break the braid inside the connector. The amount of loss in a 2 foot jumper of good quality RG-214 is insignificant compared to LMR or 9913 cable.

[Repeater-Builder] Spirit MU21CV Radio Frequencies
I know this is a bit off thread, but can anyone tell me what the actual frequencies of these radios should be. I'm getting some weird ones out of them, mid channels if you will. Like 467.761, but freq chart says that should be 467.775. Is this true or is this unit I have just off frequency? Thanks. Mathew Yahoo!
