[Repeater-Builder] Lead Acid Batteries Available At Shelby, NC Hamfest
Greetings, I have a small inventory of deep cycle lead acid batteries to offer. These are model SD 11, 2 volt at 200Ah batteries made by Fiamm. Here's a link to the info sheet: http://www.fiammamerica.com/media/productdocuments/76916255862720088431SD%20SDH%20%20Family.pdf These batteries were removed from service this year on a contract basis. The contract stipulates that one weak cell in the pack is cause for the entire pack to be replaced, so there's lots of good batteries in the packs. Unlike many wet cell batteries, these are weigh only 45lbs. each, so 270 lbs for a 12 volt string. I can deliver to the Shelby, NC hamfest over Labor Day weekend. Since these batteries take up considerable space and payload capacity (not to mention the other issues), I'd rather not haul more of them than necessary, so I'd like to make arrangements in advance. I'm asking $200 for a set of six batteries. The electrolyte levels are all good, the batteries are being charged and will be load tested prior to delivery. Please contact me off list if you'd like more information. Thank you, Robin Midgett K4IDC

Re: [Repeater-Builder] To DIN or not to DIN
Hi Tedd, I think typically DIN connectors are used in higher power situations (EME comes to mind) where the relatively small amount of current carrying metal used for N connectors just can't support the power pushed through the contacting surface area. DIN connectors solve this by having a relatively large contacting surface area. For repeater use, I don't think DINs are necessary.

It can be done. I used to work with a UHF commercial system which combined multiple repeaters to a common antenna.

Anyway, assuming that thing has useable SWR on my TX frequency (I've had that happen before, not holding my breath), does anyone have any ideas about the viability of running both repeaters on the same antenna but connecting the duplexer outputs together in to the common feedline? I've done no math, and not a lot of thinking, but is this one of those times when I might run odd multiples of 1/4 wave coax to a T at the hardline or something?

Re: [Repeater-Builder] Re:Combination of Omni and Yagi antenna
Not true at all. Since the gain of a Yagi comes from focusing the RF energy in a particular region, and that gain is measured against either an omni-directional antenna (dBi - gain in dB compared to an isotropic antenna) or against a standardized dipole (dBd), the two antennas in question in the original post (the G7 - an omni, and a Yagi) can't have the same gain. http://whatis.techtarget.com/definition/0,,sid9_gci214570,00.html The two antennas do need to present the same impedance at the frequency of interest in order for the power dividers to work as designed. The power dividers are based on the impedance matching characteristics of the 1/4 wavelength line section. If the impedance of the two antennas don't match, the power division will be skewed accordingly. The products previously offered by ZD Engineering back in the 90s all took advantage of this. ZD Engineering was bought out by another organization, and I think those people are part of this list IIRC...

Re: [Repeater-Builder] Re: Celwave Stationmaster part identification help needed - RFS is useless
Hi Eric, It appears that a faulty installation of the jumper at the sidearm is the beginning of the problems, and eliminating all the adaptors you can is the other component. Regarding repairing the antenna: is it feasible to make your own jumper pig tail (perhaps from super flex) and permanently solder one end to the antenna feed point? That would eliminate connectors that are inaccessible at the antenna. Make the jumper long enough to reach the tower, and ensure it is well attached to the stand off bracket. If the radials are what I recall, they're easy if you have the dimensions. IIRC, they're simple flat stock stainless or aluminum pieces with rounded edges, kind of resembling metal tongue depressors with a sharp angle bend in one end. I could fab them for you if you'd like. At 06:06 PM 9/7/2007, you wrote: I called RFS this afternoon. Sad times, indeed. First of all no one there could identify the connector/adapter part. Second of all, they claim no spare parts available for Stationmaster antennas. I even tried to buy a set of radials for a PD455 that has lost them, and they don't even offer them separately! Anyone have a bad UHF Super StationMaster that they want to sell off the radials or coaxial connector/adapter from? To top matters, the antennas aren't even built in the states anymore, and are contracted out to a non-RFS company. One more nail in our industrial coffin! One another note - has anyone run a PD455 with and without the radials, and noted the difference in performance? Eric KE2D --- In Repeater-Builder@yahoogroups.com, kk2ed [EMAIL PROTECTED] wrote: Good Evening, I have a PD455 Super Stationmaster that is about 12 years old. I recently replaced it due to and SWR issue. I suspected a jumper issue. But since it is so high up on a tower, I didn't want to take any chances while having the climbers rig the tower, and pay twice, so I went ahead and replaced the antenna as well as the jumper. Well, come to find out, the problem was that the LDF4-50 jumper came loose from the side arm, and the stress pulled the center pin in on the N connector, thus causing an arc condition inside the N female connector at the bottom of the antenna. To make matters worse, the actual N Female termination was half unscrewed from the bottom of the antenna. Once on the ground, I decided to unscrew it out completely. To my suprise, it looks like the antenna is actually terminated into something resembling a UHF male connector embedded into the end of the inner assembly, and a UHF female to N female adapter is screwed in at the factory, providing the N female termination as ordered I'm guessing that if some other termination (DIN or UHF) is ordered, a different adapter is screwed in. Anyone familiar with this adapter, or know where I can obtain said replacement adapter? I have some standard UHF female - N female barrel adapters, but they are much shorter and not of the quality like the Celwave unit. I don't want to trust a cheap adapter at 500ft in the air! I'll call RFS when I get a chance, but based on recent correspondence with them, I don't hold much hope getting any support from them.

What a field day site! At 07:57 PM 6/17/2007, you wrote: By George I have not seen this much talk about one topic for a while. This as really been an interesting topic. I will go in a little more on this. This former ATT facility was built in the early in 1950's.

It had 3 fuel tanks for its, generator, but here in Texas like most places 2 of them were removed, as they were underground tanks and ATT did not want to pay to have them updated. The building plans and the radio license for the station place the top of the tower at 189'. No lighting or painting required. What is amazing is that the paint is in very good shape for a station that has not been in operation since the early 1970's. Yep ATT has held on to this site for 30+ years without using it. According to records that I have seen, any enviromental issue has been taken care of, former tower paint, abatement, etc. Plus no information regarding this not having been done, has been enclosed in any of the paperwork for the sale of the facility, which I know in Texas is required to be disclosed, plus in that case, with any facility that I have dealt with on a business point, the seller is responsible for all proper repairs, or services to get the facility up to par. Tower climber certification, that is not an issue. If the ownership of the facility does fall into our hands, it will be actually owned by our parent group, which is an international emergency response organization and most members are required to be certified. I really have enjoyed all the input from those out there, and if our dream does come around, I will be sure to come back and update everyone and include photos of the facility.

[Repeater-Builder] AM-6154/6155 Amplifiers For Sale
Hello-
I have for sale several clean AM6154 / 6155 amplifiers. The
mainframes are tested for voltages, blower, and function. Cavity
drawers are silver cleaned, ready for installation of your input
circuit. {original input circuits, power sensor and LP filter
removed}. They are in very nice shape with good sockets and brackets,
no corrosion or overheating.
The cavities are without tubes. 4CX400A or the Russian GS-36B tubes
will fit nicely in these amplifiers, and provide stable, reliable
power. The 4CX250 will also work with anode adaptors, which I have a
few of, and can produce more if needed.
I have a lot of spare parts (cavities, time delay relays, various
mech. parts, and a number of extra mainframes w/o modules) plus an
assortment of spare modules.
I have schematics and various modifications for 2m, 1.25m 70cm in
Adobe Acrobat formats available. Here's a nice site with more info:
http://www.n1rwy.com/am6155.
I'm asking $250.00 each for the amplifiers, and I will crate ship.
UPS FedEx (probably DHL also) will take the package with
surcharges; figure on the package being 20 x 10 x 24, and 100 lbs.
from 37122. I'll also deliver free of charge to a mutually convenient
hamfest, (such as Dayton Hamvention) schedule permitting.
Yes, they'll do FM.

Re: [Repeater-Builder] RCA connectors NOT for power
Personally I don't like the RCA connector for power use.

Granted, it may see very few insertions/extractions, but when extracted it exposes a live pin. A pigtail on the equipment with a male connector could be used, making the power source available on a female inline connector.

That's a long ways off, more than you would normally be able to warp them with capacitance. I'm going to go out on a limb here say this has nothing to do with having the elements matched. FWIW, I've rerocked dozens of GE xtal modules ICOMs over the years never had a problem getting the xtals on frequency.

Just know the channel element cover being on or off will change the output Frequency quite a bit. So you need to ensure the alignment is checked with the cover in place. Funny...

[Repeater-Builder] MSR-2000 Help Please: Station Control Issue
Hi Guys, This one has me scratching my head; maybe you've seen it before. VHF /\/\otorola MSR-2000, configured for repeater (RT) operation by me. It was originally a line controlled station, not a repeater. I followed the jumper setting in the service manual, and some advice from readers of this list. It transmits and receives on the (still) commercial frequencies. The bug-a-boo seems to be with the station control card. If I power up the station and slide the card in, the transmitter keys immediately, and I note that the Disable LED is dimly lit. Sliding the PL disable switch to the right brings the disable LED to full brightness, transmitter is still keyed. Sliding the line disable switch to the right, the transmitter drops and the disable LED comes to full brightness. If I key the transmitter with the XMIT switch, the transmitter keys, and it will un-key when the XMIT switch is released..as long as the line disable switch is activated (in the disable position). If I key the transmitter via the XMIT switch with the line disable switch the normal (not disabled) position, the transmitter remains keyed after I release the XMIT switch; that's not supposed to happen. The above described behavior takes place with either of two station control modules, so I think the problem is elswhere. While chasing this problem, I noted that pin 19 on the station control module (Line Disable) doesn't go fully to 12V when the transmitter isn't keyed; it hovers around 9 volts. I think this partial path to ground is enough to dimly illuminate the Disable LED. Of course, if I activate the Line Disable switch, it goes to ground as it should the LED is bright. In reading the control chassis interconnect chart, I see that pin 19 (line disable) of the station control module connects to pin 18 of the DC Transfer card and pin 7 of the Guard Tone card. I removed both of these from the card cage before finding the above described keying problem. Could there be something on the back plane of the control shelf causing this? Thank you, Thanks, Robin Midgett K4IDC VHF+ Glutton EM66se
Re: [Repeater-Builder] Repeater Time Out Award
Many years ago a regular user of our wide area UHF system unwittingly timed out the system. He was driving one of several vehicles (a Suburban, not his) in our annual group trip to Hamvention. Being somewhat unfamiliar with the vehicle's accessories, he shoved the mic into a cup holder on the console, top first. In doing so, he keyed the mic in a continuous state. Some ten minutes later, the rig in the truck timed out, emitting T O in morse, which got his attention. Since several of us were in route and on the system, we heard more conversation between him and his passenger than we cared to... Anyway, later that summer the group had a gathering and presented him with the trophy..a one size fits all console accessory for vehicles with a hump in the floor with...cup holders built in!

[Repeater-Builder] MSR2000 Squelch Gate Jumpers

The manual I posess doesn't have (at least I've not yet found it) a picture of the squelch gate board showing the jumper locations. The locations are marked on the PCB, but it's a jumbled arrangement with some of the text obscured by other parts or a smeared silk screen job.

[Repeater-Builder] WTB: MSR-2000 UHF Rx
Hi guys, I'm helping the Wilson County ARC assemble a pair of VHF MSR-2000 repeaters for club use (main and back up). We'd like to incorporate a UHF Rx in the second Rx slot of the repeaters as a control input. I'd like to know what the band split options are for the UHF MSR-2000 repeaters, and which of those are desirable for ham band use. Then I'd like to know if any of you have a one or two of those available, and for what price, please. Additionally, I have various GE Motorola and RCA gear to trade with if there's any interest. I also have some TxRx UHF cavities available.

Re: [Repeater-Builder] Good Radio's for Repeater?
I've been following this thread with interest, and have a couple of points which (of course) lead to more questions. The MASTRII RF strips are the same in the repeater chassis and the mobile rigs, band for band from low band to UHF. Flexibility and convenience options (and continuous duty PA issues) aside, why is a MII repeater station better used as a repeater than a MII mobile rig? I don't know if a Micor mobile and Micor repeater use the same RF strips or not..do they? If so, then the same question applies, with the same qualifiers. Same answer? Granted, a reliable repeater is not made from a pair of whatever you can scrounge mobile rigs with a controller in the middle. (Maxar comes to mind as something in that category). Also in that line up are amateur radios with 20% duty cycle, or practically anything that says Alinco on it. Where reliability concerns are fewer and convenience issues are greater, then latitude is greater and mobile radios with a controller in the middle (port-a-peaters) become attractive. Thoughts?

[Repeater-Builder] OT..Kind of..Flat Bed Scanner Opinions Sought
Hi, I have a significant collection of service manuals for various commercial two-way radios which I'd like to scan into Adobe Acrobat and make available via the Repeater Builder web site. The makes and models include RCA 500, 700 1000 VHF UHF, and G.E. models from MASTR Exec through MASTRIII, Phoenix, MVS, and others. I'd like recommendations on flat bed scanners suitable for scanning these documents. I have two now that use the USB interface, but they're slow, and they only accommodate 8-1/2 x 11 paper. A relatively fast scanner with a larger surface (for those fold out sheets) would be nice. I suspect someone on the list knows of such a machine that they'd recommend. P.S. Purely as a preemptive measure, please don't ping me for a list of the manuals I have available just yet. I haven't gotten that far into organizing them.

Re: [Repeater-Builder] crackle in a repeater tower
Short of tightening all the leg joints, I don't know about finding the source of this type problem, but I have seen AM broadcast towers with copper jumpers wired across the leg joints to help prevent the same type of problem. The jumpers were connected with ring terminals soldered to copper braid, and the ring terminals were screwed to the legs with stainless steel sheet metal screws. The jumpers weren't weather proofed, oddly enough. I don't know if the jumpers were installed with the tower or if they were a cure for a problem that occurred after installation.

[Repeater-Builder] FS: VHF 4 Bay Sinclair Antenna Arrays
I have several (8-10) SRL210C2/C2HB*2 antennas for sale. These are arrays of four folded dipoles arranged in two pairs on a 20' tall heavy duty (sched. 40) aluminum mast. They are specified for coverage over 138-160 MHz. There are two feed line connections which exit the base of the mast; one for each pair. The coverage pattern for these antennas is slightly elliptical or nearly circular, depending on installation variables. I have scanned the spec sheets and posted them on my web site (see sig line). The antennas are located in middle Tennessee. If freight is necessary, I can get a quote via ABF Freight. Those quotes I've already gotten have been in the $170 range, plus $100 for a recommended crate. Other transport arrangements can be made. The price for the antennas is $150 each.

Re: [Repeater-Builder] PA Options for Hamtronics 6m Repeater?
How about a 100 watt PA out of a G.E. MASTRII..I have a few available. You won't need 25 watts to drive it, though, and you will need a hefty power supply. At 02:21 PM 1/15/2006, you wrote: Anyone have any suggestions for higher power in a Hamtronics 6m Repeater (REP200) I have the 25 Watt PA, and initial testing is showing the receive sensitivity far out distances the ability to transmit. I am able to get into the repeater from 50 miles, but have to be within 25 miles to hear it. I would like to have the potential for 100 to 150 Watts, if this will bring it back in line. It is currently being tested at 90 feet with 1/4 wave homebrew antenna. It has been tested at 50 feet with the same combo in another location, and the results have been the same. Both locations were temporary to get an idea of performance after isolating a duplexer problem and correcting the resulting desense problem. It is also possible that the final resting spot (197 feet elevation with Comet antenna fed by 25 feet of 1/2 hardline) will improve the balance between TX and RX. This will be 100 feet higher than the current testing location, and far better feedline in terms of quality and length. However, if the combination of higher antenna height and shorter, less lossy feedline do not bring it back in line - What would be a good choice in external PA to do the job? I know this is an open-ended question, and probably far short on info to provide a definite answer. I am only looking for possible options here. Thanks, David KD4NUE Yahoo!

Re: [Repeater-Builder] Shipping an antenna
Yes, I have shipped such packages. I believe UPS's limit is 165 total, length and girth. Your package in a PVC tube shouldn't be a problem. BTW, there are different wall thicknesses of PVC..the stuff used for drain pipe has thinner walls, but the same O.D. so the same fittings work between types of pipe. So, if it makes any difference concerning getting the item in the tube, choose the thin wall drain pipe instead of schedule 40 or some such, which is rated for higher pressure and has thicker walls. At 06:20 PM 1/13/2006, you wrote: I need to get a 10 foot long fiberglass antenna from Florida to Connecticut. It can probably be encased in some PVC plastic tubing. It'll weigh between 20 and 30 pounds when packaged. UPS and FedEx have some crazy size and weight limitations. At least the UPS web site tells me the maximum length plus girth (essentially circumference or square surface dimension) but FedEx is less user-friendly. Anyone have any experience shipping this kind of thing? It's NOT a 22 ft Super StationMaster but it IS one piece. I don't really want to spend hundreds of dollars to ship it via a commercial trucking company, especially considering what I'm paying for the antenna. Thanks. Bob M. __ Do You Yahoo!? Tired of spam?

Re: [Repeater-Builder] Re: OT - funny interference story
Granted, but distant weak signals (in my experience) are the exception on repeaters..not the rule. CTCSS on the input would have kept the wireless mic(s) from getting through the repeater, until someone keyed up the repeater with a valid signal. At that point, it would have been a game of which transmitter captured the receiver. We have a similar problem in our locale with a wide area UHF system. The Air Force has a powerful radar system on a base ~80 miles away. From time to time we hear the radar beam sweep across the input, right on frequency. It doesn't key the repeater, but it can be heard once the receiver is opened. It's annoying at worst, because most of the voice traffic on the repeater is strong enough to (almost) fully capture the receiver...except for the rare, weak signals. Then its sorry, try later when you're closer.. At 04:01 PM 1/12/2006, you wrote: Robin Midgett [EMAIL PROTECTED] wrote: Isn't that what CTCSS is for?? Nope...

[Repeater-Builder] FS: RCA 500 700 Series UHF Mobile Rigs
Greetings, I have several RCA 700 UHF mobile transceivers available in Nashville, TN. These were working when they were removed from service years ago. These radios would be good for making repeater link radios, IRLP or EchoLink nodes, or as the Tx Rx strips for repeaters, or perhaps putting a UHF propagation beacon on the air. Also in the lot are several UHF RCA 500 series; same story. The 500s have the vacuum tube P.A. All this equipment and more is available as the result of the closing of a fifty year old two-way radio business in the area...there's much inventory to be liquidated. Sorry, no list yet, but it is evolving as we pick through all the stuff. I'm asking $50.00 each for the 700 series rigs, and $25.00 each for the 500 series, plus shipping.

Re: [Repeater-Builder] Duplexer tuning with Return Loss Bridge

LJ -Original Message- From: Eric Lemmon [EMAIL PROTECTED] Sent: Dec 21, 2005 7:42 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Duplexer tuning with Return Loss Bridge Gary, A return loss bridge (RLB) is an extremely useful tool for tuning the pass function of a BpBr duplexer. That's because the bandpass response of each cavity in a BpBr duplexer is very subtle- nothing like the peak you will see in a bandpass-only cavity. Even when three BpBr cavities are in series, the bandpass response is rather wide. An RLB allows any good spectrum analyzer to emulate the reflection capability of a vector network analyzer to a sufficient degree that bandpass tuning can be much more precise. Instead of viewing the transmission bump, you can view the reflection notch- which is very sharp. With such a clear indication of the bandpass tuning, the cavity can be tuned within a few kHz of the exact pass frequency. It is essential that all interconnecting cables and connector cables be of very high quality, and the spectrum analyzer's reference oscillator be on frequency. It takes some practice to use an RLB correctly, but it can allow you to tune a duplexer with remarkable precision. 73, Eric Lemmon WB6FLY Quoting [EMAIL PROTECTED]: Gentlemen, Will be starting a new science project setting up Wacom 641 on 2 meters.

[Repeater-Builder] RCA 500/700 Series Power Amp Module
On the subject of the RCA 500 700 series (since there seems to be a knowledge base among the group)...the later models of the 500 series used a RF amplifier module to drive the PA. It is a blue package, that, I'm told, replaced (partially) a former complicated and unreliable tripler section. Did the 700 series use that same module? I'm looking for one for a friend..no luck yet.
