Input Fq is 147.915 and Output Fq is 147.315. We have a 600kHz (+) offset. Very simply, our main problem is when we run the transmitter at full power 100 watts, there is a HUGE desense on the receive side of things. When we drop the transmitter power level to around 20-50 watts, the receive side opens WAY up to a large area where people can get into the repeater.

RE: [Repeater-Builder] Wacom WP-639 Duplexer question
Good evening Eric, Maybe this is why when the trasmit power is dropped to the 20-50 watt range, the receive opens way up like it should. However, according to the spec sheets regarding the Wacom SP-639 Duplexer, it is rated for 200 watts. So, again, not sure what's going on. We will be trying other things such as adding a second ground rod outside the shack instead of the single one we use now. We will also try isolating the amp some more and replacing the coax feed line with hard line. Thank you very much. We will be contacting Wacom directly tomorrow.

Your duplexer simply cannot provide enough isolation for the power level you're trying to run.

I'm not quite sure I understand your question. The procedure puts it into normal condition. Nothing further to do. For a conventional MSF5000 (NON-trunking) that is, a radio always without the RF sensor installed, the values 00 and FF are what is loaded at factory; e.g. normal. The problem usually happens when someone replaces a CLB SCB(analog) board with CXB SSCB that came from a 800 trunking radio. It will contain the setpoint values from its previous home.

Why would a series coil antenna be a requirement? The chart works quite well for the Spectrum antennas and will probably work for any other series fed LB coil. It will not work for any antenna that is shunt fed as myself and several others found out when trying to make two non-Motorola antennas work on a fire engine. On Low Band with Utility Vehicles, I've found a number of reasons why certain low band antennas don't work well. Depends on each situation and I've recently had an install where only a shunt fed antenna would work. The maker of the Untenna antennas told me once that they could be combined in the same way but the method was different; IIRC the antenna to T cables were to be quarterwaves but were for the opposing frequency. Never tried it and that was a long time ago and no notes to back up my memory. Another document exists that details using a ball mount full length whip and a Spectrum series fed LB base load in the same shared configuration.

Re: [Repeater-Builder] lowband HT antennas
Hi Al, The most simple explanation is, the higher you go in frequency, the wider the band width. This is also relevant to the diameter of the metal of the antenna structure. The fatter it is, the more the bandwidth will increase. On low band frequency's you really really have to get it Fat to increase the bandwidth. As an example a standard Mobile whip (Not a HT antenna) at 50 MHz, may yield a 1.5 to 1 VSWR over 3 MHZ. to increase it to 5 MHZ you would need to increase the diameter to about the size of about a 1/4 inch pipe. Thats why you would see better bandwidth characteristics in a 1/4 tube constructed antenna than that of the type of a mobile whip. at same frequency. So Again thats not the exact true to a formula explanation but it gets the picture in the minds eye of the electrical characteristics of an antenna, I hope its clearer not muddier :-) Richard From: hitekgearhead hitekgearh...@hotmail.com To: Repeater-Builder@yahoogroups.com Sent: Wed, June 30, 2010 10:58:06 PM Subject: [Repeater-Builder] lowband HT antennas I know I am revisiting this again but I could use some clarification.

For instance, (and correct me if I am wrong) the mid UHF (430-470MHz) radios often all use the same 6 1/4 wave whip. What am I missing? I know that the first type of antenna is loaded and the other is a 1/4 wave whip, but beyond that I don't understand the fundamental differences that would allow one a wider bandwidth over the other. Please pardon my antenna theory ignorance Also, in relation to that, what use would be a 99 channel MT1000 unless one either programmed the frequencies on quite a narrow spread, or carried multiple antennas? Thanks in advance, Albert

Not so polular beacuse 10mW doesn't get far in cities - PMR (Public Mobile Radio), 500 mW, 446.000-446. 100, 8 channels in 12.5 kHz raster: 1 446.00625 2 446.01875 3 446.03125 4 446.04375 5 446.05625 6 446.06875 7 446.08125 8 446.09375 These radios generally have PL support. Note that in EU, the 70cm band is 430.440 MHz so it is out of our bands here. These things are VERY popular - recently bought 2 radios for $35 together with charger and NiMh cells! - Digital PMR, 500 mW, 446.100-446. 200, This is like the analog PMR but uses digital voice (this is what ICOM developed D-STAR for) Note that the American FRS/GMRS radios are simply illegal here, as these frequencies were used by law enforcement till recently (so not a good choice even to chance it).

I simply drilled and tapped two 4-40 holes on a flat portion of the outside fin, and mounted the thermal switch after applying some heat-conductive paste. I used a three-inch low-EMI Panasonic fan blowing right on the fins. This is a 45-watt repeater set for about 30 watts output.

However, using it for fan control is not only expensive, but unnecessary. A fan blowing on a transmitter heat sink does absolutely nothing immediately after the transmitter is keyed, since the heat sink is likely at ambient temperature. It takes a period of time for the heat sink to warm up, so operating the fan prematurely is a waste of energy- which may be an issue for a solar-powered repeater. IMHO, the most efficient means of fan control is also the cheapest: A thermal switch. My first choice is a Cantherm #R2005015 normally-open thermostat that closes at 50 degrees Celsius, about 122 degrees Fahrenheit. When attached to a heat-sink fin, it turns the fan on when necessary, and keeps it on until the heat sink cools below about 100 degrees F- around body temperature. This particular switch is available from Digi-Key for about $9, as Catalog Number 317-1094-ND. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@ mailto:Repeater-Builder%40yahoogroups.com yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com [mailto:Repeater-Builder@ mailto:Repeater-Builder%40yahoogroups.com yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com ] On Behalf Of na4it Sent: Saturday, May 01, 2010 9:38 AM To: Repeater-Builder@ mailto:Repeater-Builder%40yahoogroups.com yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com Subject: [Repeater-Builder] Neat kit for switching repeater devices I have started using this little kit (http://www.electron http://www.electronickits.com/kit/complete/elec/ck1614.htm ickits.com/kit/complete/elec/ck1614.htm http://www.electron http://www.electronickits.com/kit/complete/elec/ck1614.htm ickits.com/kit/complete/elec/ck1614.htm http://www.electron http://www.electronickits.com/kit/complete/elec/ck1614.htm ickits.com/kit/complete/elec/ck1614.htm http://www.electron http://www.electronickits.com/kit/complete/elec/ck1614.htm ickits.com/kit/complete/elec/ck1614.htm ) for fan control on repeaters.

Hi guys, I think this is getting off track mostly becouse of many peoples missconception about RF Power. Seems that if you have 50 watts, and can talk 50 miles, then 200w would there for talk 200 miles right? Wrong! 200w over 50 watt is only 6db so if in tern you had a 1/4 wave on your car and can talk 50 miles with your 50 watt radio, would you then expect to talk about 200 miles if you changed it to a 5/8 antenna?

Re: [Repeater-Builder] Re: DB-201 Measurements for 6 Meters?
By Design, Ground plane antennas are best top mounted, but of course its not always possible. That said, I have done a few and have found they tend to be fairly happy if mounting is at least 1/4 wave length away from the tower. See if you can picture this in the minds eye, 2 lengths of conduit, each threaded on one end and each with a T connector on the end, the 2 Ts tied together by a short length of conduit between them (Do this part first, about 12 should be enough) another 12 screwed in the top too attach the antenna. Screw the 2 longer pieces into this when you get on the tower. Mount the antenna and then slide it outwards. Check vswr and if needed play with what makes it the most happy by sliding it in or out. Then tighten down the clamps. I used a total of 4, 2 attached to 4 3/4 conduit clamps attached to the tower legs. It was relatively easy to slide it out to get it happy before tightening it up. I did this over 15 years ago and last time I drove past that area, I could see it was still up there. Even though that company is no longer there. But that tower with the antennas is still there. Makes you wonder if any of that is in use anymore.

I ask because a bandpass cavity imposes a DC ground on the transmission line, while a bandpass/bandreject cavity shows a DC open. If the antenna and/or feedline is experiencing triboelectric charging (i. e., motion static), the bandpass cavity will effectively impose a DC ground and drain the static charge. A BpBr cavity won't help the static problem, but it will clean up some spurious emissions from your PA. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@ mailto:Repeater-Builder%40yahoogroups.com yahoogroups.com [mailto:Repeater-Builder@ mailto:Repeater-Builder%40yahoogroups.com yahoogroups.com] On Behalf Of Richard MI Ranta Sent: Wednesday, January 20, 2010 9:41 PM To: Repeater-Builder@ mailto:Repeater-Builder%40yahoogroups.com yahoogroups.com Subject: RE: [Repeater-Builder] Re: current state of our lightning struck repeater.

[Repeater-Builder] RE: follow up on lightening strike last spring response
Sorry if I've been late in posting. First, the antenna and hard line is ok. We've tested that part out and its working. We think ( I ) that we got zapped through a unused phone line which is mounted behind the repeater rack. Yes, we have tested the can's using both a IRL (?sp) and a General Dynamics service monitor. They were taken apart and cleaned and retuned. Everything indicated they were functioning normally. Till we put them back in service. I don't know if they were tested with a dummy load. The technicians made many trips to the site: the technicians worked for the company that we rent the site from. We replaced all of the connectors and only found one that had scorched indications on it, but that was all. I asked if any of you knew how to find out if a can was operational, because all the test equipment that was used indicated they were ok. We finally found a workable solution. We added a fifth can, tuned to the transmit freq. That stoped the crackling noise. Now we're going to replace the can's, and go with a 6 can configuration. this is what was reconmended by the technician. Rich K8JX www.w8usa.org
[Repeater-Builder] RE: follow up on lightening strike last spring
I know its been a long time since I first posed the question on what might be causing the noise we were experiencing after being hit by lightening. After many trips to the Technical shop for testing, we replaced the repeater ( was a vertex 5000, now a Icom ur2000) and are in process of checking out controllers. The duplexers were my big worry. And yes, it would seem that concern wasn't unfounded. We started experiencing a degradation on the receive side of the repeater and then, a leakage from the cans. We had the duplexers checked out with two different service monitors and found nothing! The technician who works on duplexers took ours apart and found only a little bit of carbon, but that was it. they checked out ok. We put them back into service and the noise was there making communications impossible. We are now going to replace them with a 6 configuration instead of the four we have been using. My question to the list is, besides the noise factor and crackling noise, is there any other methode of discovering if the can's are bad or not? Yes, I did and have been losing sleep over this one. I also wish to thank Kevin and the group for all their feedback on my question I put in last summer. You helped more than you know. Rich Ranta K8JX www.w8usa.org

Re: [Repeater-Builder] Mastr II mods and parts
Hi Greg, There is no Mod to make the exciter do 35 watts. Its nominal value is about 200 to 300 mw, but normally 250 mw. The way to get about 35 watts is to modify the PA itself. You can bypass the final stages of the PA and just use the first stage. There are many types and some may get you close just of the driver stage. But then again like I say, there are many types to look at that have different configurations. The first question is what is the output of the PA you have? We would need to see the type and give you some guidance from that point of what is the best option. Maybe even a picture or the part number of that PA would help. Best Regards Richard.

[Repeater-Builder] battery
Tom, Please be advised that boating laws do not specifically require a battery to be in a box. What they do require is a battery to be securely mounted and the non-grounded terminal covered. Most folks interpret that as a battery box or bracket to old the battery in place. Most folks usually cover both battery terminals, as interpretation of the terminal issue varies state to state and officer to officer. Battery boxes as used in boating are generally vented, by the cable entrance-ways and some even have a small open vent on the top. If a battery is placed in an enclosed compartment, it is generally vented externally or via another compartment. I do not recall the precise position of the ABYC on battery ventilation, but I know they require the battery not be mounted under any electronic or electrical equipment for the sake of corrosion. In the past, I have used marine type battery boxes for radio installations and I usually vented it outside by cutting a hole in the battery box top and affixing a flexible vent line to the outside. I have experienced no complications following this procedure, either with corrosion or explosive events. Good Luck, Rich N9EMS

Without a clear identification of the whole unit, all we can determine is that it is a special part that incorporates some PE handheld modules.

The MSF has no speaker and as such was designed to use a test handset. Using a microphone gives you no way to monitor the receiver. Since the MSF has a 6-wire headset / microphone / programming jack you can use a workaround to use a more common (and hence cheaper) Maxtrac microphone. I've seen a test jig made up of a 6-wire phone cord feeding a 8-pin Ethernet style jack that was wired to match the Maxtrac mic. The pinout for that microphone is here: http://www.repeater -builder. com/maxtrac/ maxtrac-index. html The 8-pin baseboard style jack housing also had a DB-25 pigtail hanging out of it that connected to the RIB box for programming the station. See this article for info on the programming cable pinout: http://www.repeater -builder. com/motorola/ msf/msf-prog- cable.html The 8-pin baseboard style jack also had enough room in the housing for a 1/8 inch headphone jack, and you could plug a Radio Shack Model 277-1008 Mini Audio Amplifier (about $20) into it. Or instead of the Radio Shack amplified speaker you can build your own by taking a common mobile speaker and adding this circuit inside the housing: http://www.repeater -builder. com/rbtip/ audioamp. html. If you used a volume control with a switch on it you could switch off the DC power to the speaker amplifier when you weren't at the station. Then cable the amplified speaker into the drawer; connect the audio input to the audio pins on the 6-pin cable, pick up +12vDC for the amplifier from any of several places in the drawer and have a full time speaker.

Re: [Repeater-Builder] Antenna SWR = Desense?

Hi folks, Just a bit of an update... got the 6 cavity Telewave duplexer tweaked up - looks like it pretty much hit the specs in the data sheet. With a dummy load at the 'antenna' port, I used an iso-tee to inject a signal at both the receiver input, and between the antenna port the dummy load. With a weak signal, both places showed me that there was no desense. Very weak signal would hold in the repeater. However, putting the system on the antenna (a 150-160 mhz DB-224 100' horizontally 10' vertically separated) through a metal building fed with 7/8 heliax, there seems to be no end to the desense! The wattmeter shows 30 watts forward 3 watts reflected at the antenna port, if my math serves, it's less than 2:1. Can the less than 1:1 match be the culprit? Thanks, Tim W5FN

Re: [Repeater-Builder] Re: DB-4050WB Duplexer
Hi Tim, Is usually a good idea to test the Duplexer while on a dummy load. I usually like to use my Marconi 2955 Duplex mode to tune the duplexer. Once I am happy with that then I go to the antenna see how that looks. I like to use the lowest value element I can find for my bird meter to tackle the reflected power. And I like to use an HT programmed in 1 mhz steps (11 channels, so I can compare 5 mhz up and down) That gives me a reference in what direction I need to focus tuning. If you are on 440, be sure to keep reference to the transmit freq first. Then give it a sanity check on the input freq. Be safe when you head to the hill and be sure you don't go alone.

If I were to claim two Amateur frequencies let's say for instance on the HF band, and tell others they cannot use them what would most of us say? It seems to me that repeater coodination in the Amateur band is more of a courtesy than anything else. I see no reason that if and when a given repeater in not in use that like any other frequency or split in this case, that someone else can't use it as long as there is no interference to another station in operation. I know that may upset some, but we need to take responsibility for our operations as Amateurs. It's not that I don't believe in closed repeaters or wish to chastise those who do, but by default I believe they may be right on this one. I haven't even touched on the fact that repeater usage is down dramatically in most areas in the country.

Mr. Bondy is accused of jamming some southern California radio frequencies as discussed in recent CGC Communicator newsletters. A police search of his residence turned up an extraordinary amount of potentially stolen radio gear. Your help is needed. Is any of this equipment yours? Would you copy this story to others in the land-mobile and broadcast industries, particularly to equipment dealers and publications? If some or all of this equipment is stolen, the owners need to contact the Ventura County Sheriff pronto. Items #120 - 123 involve FM broadcast equipment; the rest is land-mobile gear (including repeaters) with a few miscellaneous items mixed in (e.g. computers, CB amateur radio gear). The first URL takes you to the list. The second URL shows pictures of the FM broadcast equipment and gives contact information for the Ventura County Sheriff. Communications General Corp. has been in touch with Broadcast Electronics concerning Item #120, the solid state 1,000 watt FM broadcast transmitter. Unfortunately, the serial number is a bit outdated for their records, but perhaps you or an equipment dealer would have a record of the sales transaction. Thanks for helping by looking over the equipment list and forwarding this story to others.

Re: [Repeater-Builder] Help with a CSI TP 154 Tone Panel
Hi Dick, I have a bunch of these on the air and noted same problem when I used my ICOM U 16 a while back. Check that the *123456* turns on the display. Then do the *123456# and watch closely that each key press shows up on the display. You might have one tone that is not decoded correctly. Try another device and see what happens. I Used a GE PCS and a Motorola GP 68 and they worked fine. I later tried re-tuning the repeater IF stage later on since I knew that radio worked before, and Whala, I had access again on my U16. So seems it might be a sensitivity to the tones that is going on there. I have 5 of my Mastr II stations on the TP-154's, 1 is on the TP-163. My other 2 stations that don't have the PLL exciters are using the CSI Supper 32 and the old TP-38. All of these things have been stable for many years. My First TP-154 I purchased in 1993. Its been on the air ever since. Good luck, BTW I have a Motorola Motrac Repeater I would love to wire up for the TP-154 if I could just get the manual on it. I have had it on the air on GMRS on its single PL of 103.5 for nearly TEN years. Anyone wired one of these up, I am a GE guy and not had much dealing with the Motrac other than when its 10 ton PA gave out.

Re: [Repeater-Builder] Where to install my repeater antennas
I know you all will laugh at this one, but they say necessity is the mother of invention. A while back a friend had the chance to try a tower site and wanted a simple and quick way we could check coverage. So with 2, ¼ wave NMO whole mount antennas and 2 18” satellite dish pans. I mounted both antennas. Since these mounts were not shielded inside I used a couple strips of foil tape to insure the shielding. Then panned them face to face with one then being on the top and other one inverted on the bottom. Then we dropped 2, 50’ feeds of 9913 to a Custom MVP Repeater on a car battery at the base of the tower. The Dish was set in the tower structure and laid down inside pretty nicely. We then had a couple different folks access it from various areas and we drove around checking coverage on a GMRS freq. The surprising thing was that with the RX as the top and the TX was inverted. There was enough isolation that there was no desense on the 15 watt TX and the receiver was running a nice .2 uv, 12db sinad. The location worked so well that he made arrangements on an adjoining tower at the same site. He had his GMRS there for the full term of the license and removed it when everyone started using cellular’s instead. (This was back in the MID 90’s). Oh and when he went permanent he did use a real antenna and Duplexer. But it was the same Custom MVP radio. Just thought I would share that since we were discussing dual antennas and no Duplexer options.

RE: [Repeater-Builder] Re: MASTR II PTT
It would help if you would post a schematic showing how you are wiring it, and what is is you are wanting to do. When you said there is only 1/2 volt difference between on and off, it indicates that your transistor is wired incorrectly. Working from memory (and that is suspect!), you wouldn't need any resistors in the collector-emitter circuit, just a resistor in the base circuit for current limiting, and another from the base to the emitter for bias. Additionally, if you are switching a relay, you'd need a reverse biased diode across the relay coil (if there isn't one internally) to prevent damage to the transistor. I don't think you'd need a relay to switch PTT on a MastrII, but someone can correct me if I'm wrong. A typical repeater controller uses an open collector transistor to switch external devices, which is a fancy way of saying that the transistor acts like a switch, and can be used to switch PTT. When the transistor is turned on by the controller CPU, it simply pulls the PTT line to ground, thereby keying the transmitter. Without looking up the specs of a Com port, I couldn't say if it can be used for that, especially since I don't know which control signal you are using. Someone else mentioned using the printer port and it seems to me that it would be ideal for your application.

Subject: California County Taking Actions To Silence ALL Ham Activity From: www radiobanter com San Luis Obispocounty supervisors took drastic and unprecedented action yesterday by passing an ordinance that would prohibit amateur radio operators, known as hams, from operating their transmitting stations. The measure was put in place to eliminate what officials said were health risks associated with transmitters located close to children. A legal struggle is expected. By a vote of 4 to 1 with one abstention, the governing board of SLO county took action aimed at addressing a recent Stanford University study that showed a correlation between ham radios and attention de ficit disorder and hyperactivity in children, as well as nagging reports of interference caused by radio hams operating their high-powered transmitters in residential neighborhoods. Our primary responsibility is to provide a safe environment for children to live without the dangerous effects of radio waves constantly bombarding them and causing proven neurological and psychological problems, said E. Duane Nyborg, an attorney who represented the county in several court cases in the past year. Hams are not the only culprits, but they are usually in very close proximity to children and are no doubt a major contributor to the health problems we've been seeing. The interference is just the last straw that convinced the county that something had to be done about it. Atascadero city manager Laura Lopez said that she has seen a tenfold increase in the number of complaints of interference from ham radio operators in the last six months. New housing developments which have dramatically increased the population there and placed homes unusually close to each other are the predominant contributing factor. Similar conditions exist in most of the county. We have radio hams getting into toasters, electric pianos, light bulbs, everything, from their powerful transmitters that cause all this static. Many of our citizens can't use basic appliances or watch television because of all the junk that the hams are broadcasting, she tol d the Press-Telegram by telephone. Hams can't say they didn't see this coming. They were warned by the county last year that if they did not submit to a check of their stations by officials, they would have limits imposed on their operation. Few consented to the searches, which most decried as invasive. But nobody expected a total ban on transmissions. This is outrageous. You'd better believe we're going to fight back and win. This is a totalitarian seizure of our rights that is totally illegal and can't stand up, said Frank Wilson, a local ham club president. He said there were no formal plans for an appeal yet but preparations were underway. Wilson claims that a federal preemption of local zoning ordinances, called PRB-1, delineates three rules for local municipalities to follow in accomodating antenna structures such as are used by hams. But Nyborg says that PRB-1 applies to antenna structures only, and not the transmitters used to feed the antennas with a radio signal. We know all about PRB-1. That's why we said nothing about antennas. This law is not about antennas. It goes after the root of the problem, which is the transmitters that put out huge signals that get into the brains of our children and short-circuit them out. Those are the facts, that's what the scientific evidence points to, he said at a news conference called shortly after the county's action. In 2008, a grou p of researchers in the school of Environmental Health and Safety at Stanford published their findings that exposure to ham radio signals for three hours per day increased the risk of hyperactivity and related disorders by 10% in children aged 12 and under. This effect was seen when a typical ham radio was turned on up to ¼ mile away. The San Luis Obispo city office says that up to 11,000 children in that city live that close to a ham radio station. The Stanford study showed that frequencies around 3.5, 7, and 14 Megahertz were the most harmful, but that the danger existed all the way up to 450 Megahertz and above. We know where the hams are, that information is easy to get

Otherwise many/most of the original Dos Programs operate in Windows 98se using/within a Dos Window. What you probably need right now is... A copy of the original Windows 98 (install) boot disk that tests for and loads a number of on floppy disk available CD Rom Drivers. Rare is/was the case where the mentioned disk failed to boot a usable CD rom driver. The disk boot process delivers you to a prompt of install Windows from a CD or boot to a prompt with or without a CD Rom Driver in place. From that point your machine is now booted to a usable command prompt and depending on your selection with or without a CD Rom Driver. How you deal with loading a program from a CD Rom, Hard or floppy disk from the above mentioned command prompt is another whole thread (I don't have time to type in those steps). So you need to find/obtain a copy of the mentioned Windows 98se floppy disk (and there are at least two versions). Time to learn about the programs rawread (raw-read) and rawwrite (raw-write) which allow you to capture an restore exact floppy disk images. The original programs of course required you run them on/at a dos command prompt... so that might be a fly in your soup if you didn't have the new raw-write program for Windows (mentioned below). With a copy of a Windows 98se boot floppy disk image file you can restore/make your own boot disk and boot to the command prompt as directed above. Raw read and raw write are modestly powerful programs so warnings go out to casual users who don't tend to read directions. A quick search of the net found a windows version... Lucky you. Until I did the search today I had been working with the original dos only version... http://www.chrysoco http://www.chrysocome.net/rawwrite me.net/rawwrite So in theory... after learning about, finding and installing a raw write type program you can roll your own' (make) Windows 98se boot disk... you just need the disk file image from someone really nice.

RE: [Repeater-Builder] Re: DTV et al
