[Repeater-Builder] MASTR II 10 Meter Repeater Plans
Here are my thoughts on a 10 Meter Split-Site Repeater configuration: Comments solicited. Receiver Site: A MASTR II UHF Mobile using the 10 Meter Receiver from the MASTR II Base. Reduced power output to (tbd) for UHF link. Transmit Site: MASTR II Base using the UHF Receiver from the Receive site Mobile. I need some suggestions for PL Encoder & Decoder for each site. Plans now are for an NHRC-4 Controller at the Receive Site and a PSE-508-2 at the Transmit Site. Standing by ... 73, Dick, W1KSZ

It took almost 2 years to find it, and one phone call to the pager to fix it. The final proof was standing outside the fence with one radio listening to the pager traffic and one on our repeater. After the pager traffic QUIT, the PA started the spur on our input. The statement above could well be true, as most people think of spectrum verification as being "while transmitting". In our case the temperature involved was outdoor temp, in the range of 10-25 degrees F, causing it to drift through our input passband into another repeater's passband, which further complicated the foxhunt aspect, hi! In your case, you are hearing the traffic as well, which suggests a mix to me. You might juggle the numbers a bit and see what freq would give you an interfering mix. It could be generated in the owner's idle PA (as someone above suggested ) or a totally foreign TX. As the owner seems pretty cooperative, eliminating both his TX's should be pretty easy, If you were really lucky, it would be his idle PA mixing with his active PA and the site of the fix would be in sight!

Re: [Repeater-Builder] Motorola Starpoint - Good on 2.4G??
Kris: It should be fairly easy to move it into 2.4 GHz. Be catreful, though, because there are FCC mandated power limits imposed on Wi-Fi, which is an FCC Part 15 system. Check around with your local ham radio groups because I've seen that gear moved to the 2.3 GHz amateur band. There might even be some modification info on the internet if you do a search on Starpoint+freequency+change. Also haqve a look at www.mods.dk. One other caution: Your microwave gear isn't FCC type approved/accepted for Wi-Fi. You could be looking at some serios FCC hassles if you put it into Wi-Fi service. As for your 2.X GHaantennas, they should work just fine on 2.3 GHzamateur and 2.4 GHz Wi-fi.

Re: [Repeater-Builder] Kendercom included an internal ACC Controller?
I read the ebay description, and the mention of an ACC controller I believe is just for comparison; everything I can see in the pix looks just as ours did when received from Kendecom new. The 21 w out is typical for the Nominal 30W exciter. Ours is still in service for W0CWP in Iowa. Biggest problem we had was unreliable ribbon cables/connectors.

Re: [Repeater-Builder] Height Gain figure
An antenna's gain is what it is and it doesn't change with elevation. Increased elevation just lets the antenna "see" farther. In other words, it moves the radio horizon further out...just as yoiu can see farther from the hilltop than you can from the base of the hill. Raising the antenna can also lose some coverage in close under the antenna. The main beam could look over some would-be users, depending on its down angle. Dick - Original Message - From: Chuck Kimball To: Repeater-Builder@yahoogroups.com Sent: 09 August, 2008 09:57 Subject: [Repeater-Builder] Height Gain figure At one point I had read a number for figuring out the gain you get by increasing the height. Of course at the moment I'm unable to locate that. ie: If I move the same antenna (VHF 2m) up a hill and gain 100' of elevation, but it costs me the line loss (300'), did I really gain anything. I'll figure in the line loss, and adjust the hardline to minimize the loss, but I'm looking for the number to compare how much gain (in db) did I get with the increased height. So... Anyone know what number is for gain as a function of height? or know a reference I can look up. Thanks Chuck n0nhj
[Repeater-Builder] Antennas and lightning
All you want to know about lightning strokes is in the current edition of MIL-STD-464. Dick W1NMZ
Re: [Repeater-Builder] Re: antenna question - Dip It and Scotch Kote and Kry
Ron and gang: As Dick W7TIO noted, the antenna should be selected based on the desired coverage range of the rptr. While StationMaster (SM) and similar antennas are at DC ground potential, they're ovbiously not at DC ground for RF frequencies. A lightning strike generally has a fundamental frequency around 125 KHz. The lightning channel's voltage will be in the millions just before the channel ionizes, at which time the channel impedance approaches zero ohms and the flash happens. The current in the flash channel can reach 250,000 amps. The problem is that the lightning discharge also has frequency components that extend well up into and beyond 400 MHz. There's still a lot of energy in those upper frequencies. This energy can, and usuallhy does do a lot of damage to the SM type of antenna. The good news is that the antenna provides some protection for the radio, but other protection is still necessarey, such as lkightning diverters in the coaxial cable and grounded feed-throughs where the cable enters the rptr building. The conductive window (usually a copper plate about 1/8" thick should be well grounded with a piece of lightning rod cable that goes to an 8-foot ground rod. By the way, this should be done regardless of the antenna type. Painting an SM type of antenna will extend its life in the salt air you described, but it won't add any lightning protedtion. You'll also want to cover outdoor coaxial connectors with the self-sealing tape available at Radio Shack and other places that sell such stuff. The tape eventually bonds to itself at the molecular level and provides excellent environmental protection to the connectors so they won't corrode. When you paint the SM type antenna's fiberglass radome, use an epoxy paint that doesn't use metallic powder as the coloring agent. In short, there's not much you can do to prevent lightning damage to an SM-type antenna, but it would help to side mount it on the tower well below the tower top. Mount the antenna so that it's distance from the tower is non-resonant at your operating frequency. Hope this helps.

We think the salt air got to it. We have had similar problems in the past. The antenna has been up for about 12 years. I was looking for a solution to the salt air. The painting issue came up because of this. I am replacing with a Telewave ANT150F6-2 fiberglass enclosed antenna. However, many have had problems with these and the Celwave or RFS Super Station Master with lightning. They do not handle the lightning as well as the DB224 due to, one reason, some use solder to hold the elements together inside the radome. However, mine is side mounted and hope this will not be a problem. The salt air is. I like the Station Master, but also like the DB224. On VHF one does not get easily 10 db gain out of a RFS Station Master, in fact more like 4.7 db for the 140-150 MHz antenna. The Telewave uses a longer fiberglass radome for its version allowing all the elements to be inserted. The UHF version does have higher gain, 9 db, gain. The folded dipoles allow squewing the pattern easier and more than the station master. About all it will allow is moving around and in/out from the tower. The folded dipoles are much more flexible in this issue. Lots of good responses on this. Know many learned a lot. I did. 73, ron, n9ee/r >Er.. uh...

Re: [Repeater-Builder] 1953 Motorola BaseRadio for 6meters
If memory serves, that radio is old enough to be a wideband rig (+/- 15 KHz FM deviation). You can turn down the XMTR FM dev to +/- 5 KHz, but your receiver's bandwidth is more complex to narrow it down to +/- 5 KHz. As it is now, you're nowhere near filling up its RCV bandwidth, so the remaining RCVR bandwidth lets noise through. There used to be some parts around that you could replace in the RCVR to narrowband (+/- 5 KHz), but I suspect they'd be nearly impossible to find now. You might be better off digging up a more modern RCVR and using it. 73, Dick - Original Message - From: "rod_shaner" <[EMAIL PROTECTED]> To: Sent: 17 February, 2007 11:29 Subject: [Repeater-Builder] 1953 Motorola BaseRadio for 6meters > Hi all, > I'm seeking schematics, manuals, and advice on peaking a working > unit.

Re: [Repeater-Builder] mobile repeater setup
Leo: Look around for a used Motorola GR300 repeater. They have a footprint of about one square foot and about 14" high and are quite reliable. I have a couple of them running in the 70 cm ham band. They usually come with a 120 VSAC power supply, but they run off of 13.8 VDC, so you can bypass the supply and run them directly from yoiur rig's DC source. I set mine for 20 W XMT power to keep a limit on final amp heat. They'll fit neatly into a small space in the sleeper area with room to spare. They include a built-in duplexer (UHF). There might be some on the Bay. Also, I have a Moto UHF suitcase repeater that includes a duplexer. 73, Dick W1NMZ - Original Message - From: texasexpediter To: Repeater-Builder@yahoogroups.com Sent: 04 February, 2007 15:16 Subject: [Repeater-Builder] mobile repeater setup I drive a truck OTR and at times work with FEMA.

Re: [Repeater-Builder] Effects of doubling RF output on UHF repeater?
Tony: Doubling your XMTR power will only get you a 3 dB increase in output power. That's about 1/2 a unit on a receiver's S meter. Is that worth the expense? 73, Dick W1NMZ - Original Message - From: Tony L. To: Repeater-Builder@yahoogroups.com Sent: 05 February, 2007 06:47 Subject: [Repeater-Builder] Effects of doubling RF output on UHF repeater? One of our 70cm Amateur Radio repeaters is currently outputting 50 watts into the duplexer. We're considering replacing the existing RF power amp with a 100 watt model. Current draw on the 50 watt unit is 8 amps. The 100 watt unit will draw 20 amps. Our power supply is rated at 36 amps continuous, and the duplexer is rated at 250 watts. Half of our users believe that the repeater's output power is perfectly matched to its receiver. That is, users of high powered mobile radios generally lose repeater reception at about the same time the repeater's receiver loses them. However, the other half of our users believe doubling the repeater's power output would generate increased activity since the repeater could be heard more "comfortably." We could upgrade without changing any of our other infrastructure. However, these questions arise: 1) Will the hundreds we pay to upgrade actually translate into significantly increased range? 2) Will we risk generating additional receiver noise by doubling our output power, thus losing coverage in the process? 3) Will using a higher power level shorten the life of other system components over time (e.g., power supply)? By the way, our frequency coordination would be valid even if we doubled our output power.

Get a proper battery charging unit - for the solar panel - "smart chargers" are now very inexpensive and can properly manage your batteries. 2. You should ONLY be using deep cycle cells - used in marine industry and Uniteruptable power systems -- DO NOT stop at your local automotive dealer -- car/truck batteries are totally inapprorpiate for this application. The size and capacity fo the cells must be matched to your load AND to the expected solar panel charging ability. (This is the "teeter totter" part of the design). Greg, w9gb --- Posted by: "[EMAIL PROTECTED]" [EMAIL PROTECTED] selah_102 Sun Dec 3, 2006 9:12 am (PST) Here is the info on the system and my question: Let me tell you about what I have: One 110 watt panel, one 115 watt panel, one 400 watt wind gen, two bridge rectifiers, two 1500 cca batteries, two GM300 radios, one IDer, one NHRC4 DTMF controller, one dump load circuit with two dump lines, four 300 watt 1.2 ohm resisters for the dump lines. Now when the repeater is turned on, it draws one amp and in tx it draws about 7 amps. For isolation for the panels I have one 85 amp diode on the plus and negative lines to keep the wind gen from energizing the panels with up to 41 amps. Now for some reason the panels and the wind gen are not keeping the two batteries charged. Not sure why. The panels are set for the winter setting for my location. I was at the site today to test the batteries, because the repeater was not working. Both batteries tested at 7.81 volts and the panels tested at 8 volts at ab out 4 pm. The sun was almost down. We pulled the one fuse that all the voltage goes thru and I will go up there tomorrow and check the voltage on the batteries in sun light. The current from the batteries can not back feed to the wind gen due to the bridge rectifiers (the wind gen produces ac). The wind gen can not back feed to the panels due to the 84 amp diodes on the positive and negative lines. The two batteries are not isolated from each other. On November 18 the batteries tested at 12.79, repeater was turned on. We took the batteries down to about 11.9 using an inverter with 110 volt ac test equepment plugged in. On November 24 the voltage was 11.27. On Novemner 28 the voltage was about 10 volts. I turned the repeater off (tx radio only) remotely. Then you have all the information I stated above. I will be going up there today after church. >From what all I have told you, do you see anything why the two panels a lone should not keep the batteries up? The repeater has been turned off since last Tuesday morning. But yet the batteries are still being drained. In the turned off mode, I mean the tx radio is turned off, but everything else is still on. The last three days have been sunny day here in Yakima, with no wind for the wind gen. I am at a loss of what is going on; the batteries are getting weaker. Why? Rod

(100 watt) My understanding is that I will be down to about 12.5 watts at the antenna on the tx side. Is this correct math?Thanks again for your help and continued support for those of us who are not radio literate. Yahoo!

Re: [Repeater-Builder] Quick GMRS repeater w/ Radius m10 and RICK
Jan: You program the radios as conventional units. The RICK will do the repeater chores. I have a couple of UHF GR300 rptrs. They each use a GM300 mobile, a RICK and a power supply. Each radio is programmed as a conventional and both have the rptr XMT and RCV freqs programmed in. That way, I can swap the radios if one of them fails. For instance, if the XMT radio's XMTR fails, I can move it to the RCV task and vice versa. 73, Dick - Original Message - From: "N6YV" <[EMAIL PROTECTED]> To: Sent: 26 May, 2006 08:05 Subject: [Repeater-Builder] Quick GMRS repeater w/ Radius m10 and RICK > Greetings to the group.

Re: [Repeater-Builder] Portable Repeaters
Steve et al: The various amateur repeater coordinating groups have no official FCC authority or mandate to control spectrum or issue repeater pairs. As a practical matter, however, the FCC will almost always support a coordinated repeater over a non-coordinated one in matters of interference. This is in keeping with the FCC's mandate to prevent interference. Fortunately, the vast majority of hams are a cooperative lot and generally work with their local coordination group to keep repeaters from causing interference to each other. I have a portable UHF repeater on GMRS and one in the ham band and have used them where I live. So far, so good and no problems.

Re: [Repeater-Builder] Newer IC-FR3000 program in the HAM Bands?
Chris: I've decided to abandon Moto, Kenwood, Vertex, etc., for repeaters and go with a little known but very excellent one that easily covers amateur and commercial bands. The company is BridgeCom Systems in MO. www.bridgecomsystems.com I just ordered one in VHF for 2 m and one in UHF for 70 cm. I ordered the UHF with integral duplexer. 40 W and the price is $1349. The VHF one will need an outboard duplexer for the 600 KHz split in 2 m and costs $995. I think these are special ham prices. They're rack width (19"), 14" deep and 3.5" high. I'm not advertising them or making any $ from this. I'm just very impressed with the design and construction and quality and the audio is equal to anything Moto ever built. I could have ordered the UHF without the duplexer for use with an outboard power amp, but 40 W is plenty for my application. They interface easily to all sorts of outboard controller/autopatches and include many onboard features, such as multiple CTCSS, etc. Their software runs under Windows and only needs their serial cable between the PC and rptr. Ron said he's working on a USB interface, since many laptops no longer include a serial port as standard. 73, Dick W1NMZ - Original Message - From: "ochf13" <[EMAIL PROTECTED]> To: Sent: 05 May, 2006 21:14 Subject: [Repeater-Builder] Newer IC-FR3000 program in the HAM Bands? > Hello, > >Will the newer IC-FR3000 VHF repeater program to 146.880-?

Re: [Repeater-Builder] Strange Repeater Problem
Aaron: Sounds to me like an antenna radiation pattern problem. Since both antennas show good VSWR, I think the 4-bay folded dipole is radiating enough energy straight down to the radio.

Re: [Repeater-Builder] Building Repeater
Will, I think that almost any antenna will give you the 1/2 mile coverage you need, but you might still have problems inside the building, considering the metal roof's shielding. I assume you're installing the rptr inside the building, so two ideas come to mind. 1. Use a Wilkinson-type power divider and place a unity gain antenna inside the building and another one on the tower outside. You can mount the antenna on the side of the tower and place it a non-resonant distance from the tower. 2. Use "leaky" coax cable to go from the repeater to the place where the tower antenna's feed line goes through the building to the tower antenna; then use regular coax (such as 9913) from there to the tower antenna. "Leaky" coax cable is made with resonant slots in the outer conductor. It's used in tunnels, mines, tall buildings, etc. As I recall a hotel in Reno, NV, had a coverage problem with its UHF rptr feeding an antenna on a roof mounted tower. They installed "leaky" coax in their elevator shaft and that solved the problem. They got great coverage inside the building and for several miles around Reno. Hope this helps.

It all may now be moot because, We all should be aware of legislation being proposed in many states such as "Driving While Distracted" or "Inattentive Driving" laws. These new laws will curtail mobile radio operations. CT, NY, NJ and DC already have laws prohibiting people talking on cell phones while driving. A proposal in NJ while not yet introduced for voting but being formulated: New Jersey clarifies that a distracted driver may be charged with reckless, careless or unsafe driving when so warranted, a law enforcement officer may charge a person with a violation if that person, while operating a motor vehicle, engages in distracting behavior including, but not limited to, the use of communications technology such as wireless telephones, pagers, facsimile machines, locator devices, AM/FM radios, compact disc players, audio cassette players, video players, citizens band radios, and dispatch radios; engaging in personal grooming; consuming food or beverages; reading; or tending to unsecured pets. So heads up, be careful, keep one ear to your state capitol and the other to the mobile rig while driving under those low hanging tree branches. Soon we may not need mobile antennas. Gary K2UQ Yahoo!

Re: [Repeater-Builder] Two bands, one antenna, many problems?
Dave, the problem with the diplexer that burned up is that its power rating was given in PEP and not CW. You need to find one rated for your total power in CW. As you know, PEP is a low duty cycle mode in SSB. I think your Comet unit was faulgty going in because it shouldn't have failed at those power levels. Have a look at the Diamnd MX72D 100 W CW UHF; 150 W CW VHF Note that its power rating is fotr CW and not PEP. 73, Dick - Original Message - From: Dave VanHorn To: Repeater-Builder@yahoogroups.com Sent: 24 April, 2006 13:32 Subject: [Repeater-Builder] Two bands, one antenna, many problems?

What's up there now, is similar to a Comet GP-9 dual band antenna. We're running the VHF pair now 146.85- at 30W, without any issues. We're coordinated for another pair at 441.9+ and 50W I had a comet bandsplit unit (they call them duplexers, but I'm not going to for obvious reasons) which suffered an internal meltdown at this relatively modest power level, despite a nameplate rating of 800W pep. So I'm looking for feedback on bandsplit units, and basically anything that I can do to make this work as well as possible. We are still looking for another site, but that has proven very difficult.

LOL!! 73, Dick W1NMZ - Original Message - From: n8rqu To: Repeater-Builder@yahoogroups.com Sent: 01 April, 2006 11:27 Subject: [Repeater-Builder] FCC to Deregulate Amateur Radio by 2008 In a bold move the Federal Communications Commission has decided to deregulate the Amateur Radio Service. This comes at a time when budget cuts within the Commission are forcing its Enforcement Bureau to shut down by 1 January 2006. A spokesperson for the Commission stated that since Amateur Radio operators are supposed to be self-policing that this new move "should not pose a problem." And that it would also "solve the whole issue of restructuring." This news has come as quite a shock to many in the Amateur Radio community, striking up many heated debates. "Basically we're being told that we're on our own as of 1 January, 2008", said a highlevel League staff member. In the interim between 2005 and 2008 Amateur Radio operators are expected to act just as they do now. "Nothing's changed yet, and all the rules and regulations are still in effect," said a spokesperson for the Commission. All of this is set to change however, starting in 2008. On 1 January 2008 Amateur Radio in the United States will cease to exist as an official radio service. At that time it will be up to the operators to make up their own rules and regulations and to enforce them. To clarify one other issue, "call signs that have not already been issued will all be available on the 'honor system'," said another Commission spokesperson. The band-plans and power limitations are expected to stay the same. Look for more information on this late-breaking news story as it becomes available. Yahoo!

Re: [Repeater-Builder] AGT = IMTS ?
Eric, in my humble opinion, the cellular system should have stayed analog. >From what I've read, the dropped call rate for digitals is about 8 times that of the analogs. The only advantage to going digital is thye ability to crowd more traffic onto a given bandwidth. TNX for the infoi. 73, Dick - Original Message - From: Eric Lemmon To: Repeater-Builder@yahoogroups.com Sent: 26 March, 2006 09:56 Subject: RE: [Repeater-Builder] AGT = IMTS ? Dick, You have pretty much described the primary feature of the IMTS (Improved Mobile Telephone System). Although there were 11 channels available, even large cities normally had no more than seven or eight assigned. One vacant channel was always transmitting an "idle tone", which all IMTS telephones would seek out and park on. When a base-to-mobile call was initiated, each mobile radio would listen for its unique ID number. When a mismatch occurred, each mobile unit would disengage from that channel and seek an idle tone on another vacant channel. The central office equipment would establish the idle tone on another vacant channel, to capture all of the mismatched mobile units. Obviously, every mobile unit except the one that was called will quickly be monitoring the new idle channel. The called mobile transmits an acknowledge tone, and the CO then connects the caller and called parties together. It's interesting to consider that the analog 800 MHz cellular telephone systems that are still in use today use exactly the same process. Both the Block A and Block B cellular frequency plans include 21 control channels: Block A is 879.390 to 879.990 MHz at 30 kHz intervals, and Block B is 880.020 to 880.620 MHz at 30 kHz intervals. Each cell site transmits a continuous data stream on its assigned control channel, and all mobile phones monitor this channel. The data stream tells each phone where to go when a call comes in, where to go when placing a call, and what control channel to go to when the signal drops below a specified level. Although most carriers are moving to digital systems (CDMA, PCS, GSM, etc.), the analog 800 MHz systems will be around for a few more years to serve the dwindling group of hangers-on. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Dick Sent: Sunday, March 26, 2006 8:44 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] AGT = IMTS ?

Re: [Repeater-Builder] lightning arrestors
Steve: I like Polyphaser lightning diverters (they don't really "arrest" it, they just divert it). I use one at the antenna and ground it sewcurely to the tower (assuming the tower is well grounded), and one at the point where the coax goes into the copper "window" in the side of the building. The copper plate is, of course, well grounded. Also, put a 360-degree loop in your coax where it's horizontal between the tower and the building. This provides a higher impedance point that helps attenuate the lightning energy. Many AM broadcast stations use this "lightning loop" technique. FWIW, I spent a lot of my EE years at the Lockheed Skunk Works designing lightning protection technology for military aircraft. 73, Dick W1NMZ - Original Message - From: Stephen Rice To: Repeater-Builder@yahoogroups.com Sent: 02 March, 2006 06:51 Subject: [Repeater-Builder] lightning arrestors Hi all, I had a question that I believe some of you can answer!

What those individuals did should not be forgotten. But if the efforts of Hams are worthy of praise, then are they not worthy of publicity? If the efforts of Hams are worthy of publicity, then are they not worthy of support? If the efforts of Hams are worthy of support, who then will take advantage of that opportunity? Is that not a question yet to be answered? Often, Hams are viewed by government and private organizations as liabilities with nothing to add. While this may be superficially arguable, at the end of the day it is not likely factual. Some assets and services are just difficult to put a price on.Photo opportunities may be all we have to offer in exchange for what we need to occasionally provide an emergency communications system. Furthermore, I do not believe that proof of what we offer is enough for some people so maybe we should not take that course. What course do we take? I really don't know what is best, but think of this. "When banks compete, you win." Let the government and private organizations compete for the photo opportunities that supporting the Amateur Service might bring. Let us be ready to supply equipment, expertise and operators.

[Repeater-Builder] Fw: Praise for the hams!!!!
With all the worry about the fragile communications infrastructure in times of disaster, it seems that we hams are being recognized as an adjunct infrastructure that isn't nearly as fragile. 73, Dick W1NMZ The White House today released its review of the federal response toHurricane Katrina, which, according to a statement, "identifies the systemicproblems in Federal emergency preparedness and response revealed byHurricane Katrina - and the best solutions to address them." The reportincluded 17 lessons the Executive Branch learned after reviewing andanalyzing the response to Katrina; made 125 specific recommendations to thePresident, and identified 11 critical actions to be completed before thefirst day of the 2006 hurricane season. The report also included a section titled, "What Went Right" in the Katrinaresponse, which singled out amateur radio operators for particular praise: *"Other organizations worked tirelessly to assist emergency responders that,due to the storm, did not have the equipment and means to effectively carryout their duties. Amateur Radio Operators from both the Amateur RadioEmergency Service and the American Radio Relay League, monitored distresscalls and rerouted emergency requests for assistance throughout the U.S.until messages were received by emergency response personnel. A distresscall made from a cell phone on a rooftop in New Orleans to Baton Rouge wasrelayed, via ham radio, from Louisiana to Oregon, then Utah, and finallyback to emergency personnel in Louisiana, who rescued the 15 strandedvictims. Ham radio operators voluntarily manned the amateur radio stationsat sites such as the National Hurricane Center, Hurricane Watch Net,Waterway Net, Skywarn and the Salvation Army Team Emergency Radio Network."

The problem with using galvanized is that the coating is zinc, which is a very active metal that corrodes easily.

Re: [Repeater-Builder] "Rusty bolt" help!!
Fraser: If it is a "rusty bolt" effect, it an be a bear to find the particular offending item. Typically, a "rusty bolt" will generate more than just a single frequency. The actual effect is interesting. The "rust" can also be another kind of corrosion that forms an oxide between the bolt and the material it's fastening. Of course, rust is also an oxide. The result is a crude semiconductor that gets saturated with RF and generates RF noise that's rich in harmonics. I had a similar problem when I was an EE at the Lockheed Skunk Works. I used a signal generator and a spectrum analyzer and pumped RF into what seemed like a zillion fasteners. At the same time, we listened with the spectrum analyzer until we found several fasteners that resulted in a lot of RF peaks when excited with RF. We replaced the fasteners and all was well. As you can see, this is a long, tedious project, but it does work. In your case, you can use a scanner tuned to a harmonic of your repeater's output frequency. Make sure that what you're hearing on the scanner only happens when you key the repeater and make sure the repeater itself isn't generating the harmonic you hear. If you find that it's a fastener causing the problem, make sure that the replacement process includes oil on the threads and a good sealant around the fastener head and where the nut goes on. As someone else mentioned, it could also be intermod. If it is, you'll need a list of all XMTRs at the facility and some intermod software to see if your RPTR XMTR is mixing with another signal and coming out on your RCV freq. Feel free to email me off list.

Re: [Repeater-Builder] generators diesel to propane
Well, gang, I'm a dedicated diesel nut with a Case 580 backhoe, a John Deere 1070 utility tractor, a Dodge/Cummins pickup and I just sold my old 1981 Mercedes Benz 300 SL turbodiesel. However, when it came time to install a standby generator for my home, I opted for a propane powered one. The reason is simple: fuel storage. Stored diesel goes bad, even with anti-algae preservative in it. I have a 300 gallon propane tank at home for cooking and heating and running the generator. The tank is filled regularly and the stuff can be stored for incredible lengths of time without going bad. The generator runs for an hour a month on an automatic timer and always starts right up.

"Wet Stacking" causes the engine to smoke and run rough because the injectors become carbonized.

The Wacom duplexer I just bought has a 175 watt rating but it uses RG142 coax and has a permanently-wired connection to the antenna port (i.e. it does not use a separate TEE connector). I would expect the power rating to be lower as one goes up in frequency. But if I should exceed the power level, will the coax arc? Will the coupling loops get deformed? Will the notch adjusting capacitors arc? What's there that really limit the power? Thanks. Bob M. __ Do You Yahoo!? Tired of spam? Yahoo!

Make sure you install them strictly according to the manufacturer's instructions. The crimp types are OK, but the special crimping tool price tag might short circuit your pacemaker!! Do you recall what was the frequency on the MSF5000 repeater when you sent it to me? At long last I'm finally getting around to putting it up and running with autopatch.

Re: [Repeater-Builder] 6 meter repeater with 2 meter link?
I don't know where you're located, but out here in CA, link radios have to be at or above the 222 MHz band. Double ditto if you're sending control sigs over the link. In most areas, 2 m is too crowded to allow use of that band for linking. You might talk with your local coordination group about it. 73, Dick - Original Message - From: "rthollenbeck" <[EMAIL PROTECTED]> To: Sent: 28 January, 2006 06:26 Subject: [Repeater-Builder] 6 meter repeater with 2 meter link? I have a good site avaialible to me (2 good sites) for a repeater. So I was thinking about putting in a repeater on 6 meters Is there any good reason why I should not link a the sites on a 2 meter fequency. I have Mastr II for 6 meters and I have access to a low power Mastr II for the link that will tune to 2 meters. I don't have a UHF mastrII Yahoo!

Re: [Repeater-Builder] Repeater Offsets and Vanity
Works for me!! Dick - Original Message - From: "Paul Yonge" <[EMAIL PROTECTED]> To: Sent: 27 January, 2006 17:45 Subject: Re: [Repeater-Builder] Repeater Offsets and Vanity Dick - That's a good idea. I was thinking about a couple of six-packs of ARK Light in the cooler, though.
