[Repeater-Builder] Duplexers
Is it OK to get some kind of storage container or something like that and put my duplexer outside? What would be the risks of doing so? I am in Florida so lots of rain and heat but no freezing months or anything like that? Thanks, Vern KI4ONW
Re: [Repeater-Builder] Duplexers
I would think that at the least you would want to build a small building, even something close to a large dog house, 3'D X 4'W x 4'H. Leaves at least a little room to breath and work around, heat may be a factor depending on the cans you use and may send them a bit out of tune from the hot/humid summer months to the cooler less humid winter ones. Maybe a hinged lid for ease of access and a padlock. Worked a several sites I have seen but just a small box, that may be too easy to blow around, steal, no room to work, but depends on where you are putting it as it is all relative. --- On Mon, 10/27/08, Mung Bungholio [EMAIL PROTECTED] wrote: From: Mung Bungholio [EMAIL PROTECTED] Subject: [Repeater-Builder] Duplexers To: Repeater-Builder@yahoogroups.com Date: Monday, October 27, 2008, 9:14 AM Is it OK to get some kind of storage container or something like that and put my duplexer outside?

[Repeater-Builder] Telewave BrBp Problems
Hello all, I recently came into the chance to acquire a 2Meter repeater coordination and jumped at the chance. I have used some new and old equipment for the job. Where my problem starts is with the duplexes. When field tuned I have no receive signal when the transmitter kicks in. We tested the cans, upon doing so I notice a problem on the receive side. Tuning them I would put 10watts in and get 10watts out on the receive frequency. Then I switch the radio over to the transmit frequency and I have 10 out of 10 going through when tuned for the receive frequency. I am at a total lost as to what I need to do to solve this problem. It seems that the cans are not cutting out the frequency as they are designed. More info on the cans: Telewave 2 Meter, 4 Cavity, TPRD 1554. Thanks KC9JOY
[Repeater-Builder] New BOM Repeater Coordinators Meeting Proposed by WA6ITF
Bill Pasternak, WA6ITF, Editor of the Amateur Radio Newsline Report and Editor of the Looking West: The VHF FM and Repeater Column in WorldRadio magazine has proposed in his WorldRadio column that a new BOM, National Coordinators Meeting to be held. The article can be found in the November 2008 issue of WorldRadio magazine or below. LOOKING WEST: THE VHF FM AND REPEATER COLUMN Edition 117 - November 2008 By Bill Pasternak, WA6ITF IS IT TIME FOR ANOTHER BOM? BOM? Oh, that means Big Old Meeting and maybe its time for another one. As longtime readers know, in October of 1995 most members of the nations volunteer ham radio repeater coordination community, along with the ARRL, the FCC, several then-emerging special interest groups (Packet and Fast Scan ATV) traveled to Charles, MO. The location, a suburb of St. Louis had been chosen because it was almost in the middle of the country and at that time was a hub for the late (though not lamented) Trans World Airlines. That translated into it being about the same travel time from either coast on an airline that served it nonstop from most major U.S. cities. A lot was accomplished in St. Charles that weekend. In this writers opinion one of the most important was the being the beginning of a real dialog between the coordination community, the FCC and the ARRL. This lead to the creation of the National Frequency Coordinators Council (http://www.arrl.org/nfcc/) which is an organization comprised of and representing the recognized amateur radio frequency coordinators of the United States and its possessions. The standard-bearer for all coordination efforts across the nation -- if you will. The other big accomplishment was one that eventually proved to be far more important than the formation of the NFCC. That being the trust now far more apparent in the coordination process that has developed in the overall national ham community following some rather detailed articles that appeared in here in Worldradio, as well as in CQ-VHF and the now departed 73 magazine. There was also the widely distributed video shot by Henry Ruh, KB9FO, (now AA9XW) that chronicled the entire two days. Fast forward 13+ years. Today, the coordination community is working on ways to accommodate narrowband digital modes. Not just D-Star, but other methods of digital voice and combined voice / data communication that have similar emissions characteristics. They have been doing so for a while now, and several plans have been provisionally adopted. But the problem is that no two plans are really alike. And as was the case back in the late 1960's, this in itself is leading to some fair amount of ridicule aimed at coordinators from within the general ham radio community. To this writer, it seems that the needs, wants and desires of the general ham radio populace is to have a single, unified national plan that every repeater -- analog or digital -- can adhere to. A plan to works with today's predominantly analog FM world while making way for any form of digital voice or combo voice and data circuits that we within the ham community might develop and introduce in the coming years. And, do it all of this under the watchful eye of the ham radio public. Coordinators: You have done it before. You proved in St. Charles, Missouri, that you can work in unison and under the eye of public scrutiny to solve problems placed before you. And in doing so you quite literally made ham radio history. Something to be very proud of. Now, the entire paradigm of ham radio utility communications on 50 MHz and the bands above is beginning its shift away from analog and over to the world of digital. While analog FM will be with us for years to come, as we progress in time there is going to be more and more of a demand placed on the collective coordination community by those wanting to convert to digital voice and those wanting to introduce it to a given geographic area. But the good thing is that there is still time to find a meeting room some place in middle-America to come together and come up with a plan that makes it easy for Joe Digital Ham to drive coast to coast and border to border and never have to stop to reprogram his/her radio because the bandplan has radically shifted at a state border. Coordinators, you are being handed the chance of a lifetime to do some significant good for all. As one who was there in St. Charles I can tell you that a lot of the misunderstanding of one another's motives disappears quickly once folks are in the same room, face to face, exchanging ideas. In my opinion, St. Charles was the turning point where -- after years of mistrust -- the nations ham community came to realize that coordinators were real people. That they were like themselves but dedicating their time and money to insure domestic tranquility on the VHF / UHF repeater subbands. And based on the success of the first, maybe another B-O-M

[Repeater-Builder] ARLB016 Next Round of PAVE PAWS Mitigation Contacts Begin
SB QST @ ARL $ARLB016 ARLB016 Next Round of PAVE PAWS Mitigation Contacts Begin ZCZC AG16 QST de W1AW ARRL Bulletin 16 ARLB016 From ARRL Headquarters Newington CT October 24, 2008 To all radio amateurs SB QST ARL ARLB016 ARLB016 Next Round of PAVE PAWS Mitigation Contacts Begin On Wednesday, October 22, the FCC notified the ARRL that they would immediately begin making direct contact with owners or trustees of approximately 40 repeaters. The US Air Force identified these repeaters earlier this year as contributors to the harmful interference affecting the Beale Air Force Base PAVE PAWS radar installation near Sacramento, California. ARRL understands that contact with individual amateurs will be made from the DFCC's San Francisco office, said ARRL Regulatory Information Branch Manager Dan Henderson, N1ND. The owners of these newly identified repeaters will be provided the operating parameters determined by the Air Force engineering unit's testing to be necessary to mitigate the interference. The owners will be requested to meet signal strength limits as soon as possible. The ARRL Lab and staff are available to answer specific questions for the owners of these newly identified repeaters and to provide technical information to assist them in implementing the mitigation. Henderson said that as the Amateur Radio Service is a secondary user on the 70 cm band, It is important for amateurs to remember that it is 100 percent our responsibility to eliminate harmful interference to the primary user. While we realize that this is and will continue to be an ongoing process, this third round of mitigation should mean that each of the known repeaters in the affected area have been tested at least once. How the FCC will address approximately 50 repeaters previously identified as interference contributors -- but which have not apparently completed the required modifications -- still remains. Nor is it clear when a process by which new coordinations can be issued in the area might commence. Henderson reminded amateurs that It is important to remember that this isn't a one-time solution. The amateur community needs to remain aware of this problem and responsibly utilize the band in the future to avoid any large-scale problems such as those we have experienced in this situation. /EX

Re: [Repeater-Builder] Duplexers
Vern, This will probably raise some eyebrows, but I put up a ham repeater on the top of an 18-story office building in Orlando, and will tell you what i did. I used a very stout, steel rack box, cast off from the computer industry, sealed the few holes in it, weatherstripped the door and gasketed the latch, painted it with a light almond-colored Rust-O-Leum (similar to that beige used on zillions of computers) and put it out there with no ventilation whatsoever. It held an Astron supply, a UHF Mastr II mobile converted for dull duplex and running about 25 watts, an S-Com 7K controller, and a TX-RX duplexer. The only path for heat dissipation was whatever conduction transfer happened through the surface area of the metal cabinet. I used an attic fan thermal switch tied to a controler logic input to fire a macro and change the courtesy tone whenever the switch's 119-degree F threshhold was hit. Even on the hottest summer day and with heavy repeater use, it never tripped. I later mounted a digital thermometer which recorded highest and lowest observed temps on a rack panel, put it in the cabinet, and watched it through part of a summer. The hottest the inside of the cabinet ever got was about 4 degrees above ambient. If I recall, the highest ambient temp recorded by the NOAA for Orlando during those weeks was 94, and the highest recorded temp in the cabinet was 98. I did find a little condensation pooled on the floor of the cabinet once when made a visit. I bought a Damp Rid cup, a dessicant product designed for use in residential closets, from Ace Hardware, and never had that problem again. After I left town, the guys who took over the repeater added a 100W HF remote, IRLP node in the cabinet, and even provided some rack space to a Part 15 wireless internet provider in barter for their wireless connection for IRLP. Apparently the extra heat was not an issue. The repeater was installed in 1995. It's still there. By the way, when the repeater was still in its early stages, using solar power and 2-watt Repco transmitter strip, I did enclose the whole thing in a Rubbermaid Action Packer storage box. It didn't work out so well. In the Florida sun, the lid and the box will expand unevenly during warm-up, and spend part of each day misaligned, letting small insects find their way in, sometimes in large numbers. After a few weeks, it will get so beat up by UV that it will start to crack and warp. My feeling in taking the approach I did was that in that climate, bugs and condensation would be bigger problems than heat, especially for a moble rig designed to work properly in a car trunk. If you limit the ingress/egress of ambient air, and have equipment which holds the inside of the cabinet even a degree or two above outside temp, you will avoid condensation in the equipment itself. If you put just a duplexer in a box by itself, there will be very little heat generated inside the box, especially when the repeater is idle, so condensation may be a bigger issue for you. I'm guessing a duplexer that gets wet inside is no fun. I learned alot with that repeater. It started out with a cheapo hamfest duplexer, Belden 9913 jumpers and feedline to a Cushcraft Ringo Ranger, and a Repco UHF data receiver board with a homemade squelch circuit and a Motrac helical front end grafted on. Needless to say, there were newbie mistakes I wouldn't make again. But I was very happy with the way the cabinet worked out. Your mileage may vary. There has to be a reason they sell high-dollar NEMA cabinets with their own air conditioners, but they probably won't sell one to me! 73, Paul, AE4KR - Original Message - From: Mung Bungholio To: Repeater-Builder@yahoogroups.com Sent: Monday, October 27, 2008 7:14 AM Subject: [Repeater-Builder] Duplexers Is it OK to get some kind of storage container or something like that and put my duplexer outside?

[Repeater-Builder] MastrII PA Rack Mount
Hello all, I have the need to mount a MastrII PA in a standard 19 inch two post rack as opposed to it being mounted on the back of the repeater. I believe I'll need a set of ears or tabs that will mount to the PA and extend it so it mounts into the rack. If anyone has done this and has information, including pictures, it would be greatly appreciated. Thanks! Adam N2ACF

RE: [Repeater-Builder] MastrII PA Rack Mount
I have the need to mount a MastrII PA in a standard 19 inch two post rack as opposed to it being mounted on the back of the repeater. I believe I'll need a set of ears or tabs that will mount to the PA and extend it so it mounts into the rack. How about using one of the PA frames from a high-power station solid-state station? I don't have an M2 PA in front of me to look at, but I would guess it's maybe 17 inches across instead of 19? How about just getting two pieces of 2 flat aluminum stock, each cut to the height of the PA, drill holes for rack mounting, and holes to line up with the existing mounting holes on the PA heatsink and bolt it on? The Depot and other hardware stores sells aluminum stock (flat, angle, tubing, etc.), not sure how wide they have though. Or, take a blank rack panel of about the same height as the M2 PA and cut off each side so that you're left with two strips, each already pre-drilled for the rack holes, and then just drill the holes to attach it to the PA? The blank rack plate would be best cut with a band saw. Lacking that, you can probably do well enough using a circular saw and an abrasive cut-off blade. Safety first, wear eye/ear protection. --- Jeff WN3A

RE: [Repeater-Builder] 900mhz dup.s
Can these 900mhz dup.s be used on 900mhz VOICE repeater? They were on a paging system and are Bp dup.s. Without measuring the rejection at whatever offset (12 MHz, 25 MHz, etc.) they would be used at, it's hard to say whether or not two pass cavities on each side would afford enough isolation. The orientation of the coupling loops will obviously play a roll in determing rejection and insertion loss. That black thing where the tee is - it has fins that make it look like a reject load? Seems strange. Or is it just a standoff to support the tee? I have some other big Wacom cavities like that which were part of a combiner, but the standoffs for the tees and star junctions were just metal posts, they don't like anything like that black gizmo. Curious. How much are they worth? Depends on who's buying them :-) --- Jeff WN3A
Re: [Repeater-Builder] MastrII PA Rack Mount
Jeff and Chuck, Thanks for the replies. Not being familiar with the aluminum stock method, I'll give that some more thought. I'll see what Home Depot has to offer. I think I might have a blank rack panel to cut so I'll give that a shot too. Chuck, I'd be interested to see the your pics but I didn't get them.

RE: [Repeater-Builder] GE Power Amp
Gary, Your GE Mastr (note- no e) PA number did not include the Group number, but I will assume you meant the 19D424872G1 unit. If so, your PA is probably a 40-watt unit found in LBI-30751: www.repeater-builder.com/ge/lbi-library/lbi-30751e.pdf Although perhaps not relevant in this case, the Group Number often is vital in identifying a module's frequency band, features, capabilities, and options. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Gary Sent: Monday, October 27, 2008 6:54 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] GE Power Amp Hello group, I have a possible GE Master Power Amp I would like to confirm exactly what it is .

[Repeater-Builder] Re: 900mhz dup.s
You may be right Jeff...it is a load of sorts. One piece but 3 ports. You would think by taking out the transmitter load (or what ever it is) you might could use one side for the rx and one side for the tx. I guess cabling would have to be reconfigured. Shame.

[Repeater-Builder] Re: 900MHz Duplexer
Re: 900MHz Duplexer The black stubs look like generic 2 way 50 ohm power divider - combiner assemblies... although the heat sink look might throw you off a at first glance. Sometimes paging transmitters are set up to be frequency agile... This filter assembly appears to be set up as two parallel band pass filter assemblies for a frequency agile paging transmitter. The cavities should make a decent 900 MHz duplexer if you have the proper coax probe ports and cables configured, which is not a super easy task but quite doable. Better to reconfigure it as a BpBr duplexer or this would make a fairly neat transmit combiner. cheers, s. georgiaskywarn [EMAIL PROTECTED] wrote: You may be right Jeff...it is a load of sorts.

RE: [Repeater-Builder] ARLB016 Next Round of PAVE PAWS Mitigation Contacts Begin
Wouldn't it be a lot easier oneveryone including the AF if they just confined their ops to 420-440 and left hams repeaters alone on 440 to 450 Mhz. Seems to me like another big government mess devoid of any common sense. In fact we have yet to even get a simple answer from them as to how wide their guardband is that they do not operate in right next to the band edge.

The US Air Force identified these repeaters earlier this year as contributors to the harmful interference affecting the Beale Air Force Base PAVE PAWS radar installation near Sacramento, California. ARRL understands that contact with individual amateurs will be made from the DFCC's San Francisco office, said ARRL Regulatory Information Branch Manager Dan Henderson, N1ND. The owners of these newly identified repeaters will be provided the operating parameters determined by the Air Force engineering unit's testing to be necessary to mitigate the interference. The owners will be requested to meet signal strength limits as soon as possible. The ARRL Lab and staff are available to answer specific questions for the owners of these newly identified repeaters and to provide technical information to assist them in implementing the mitigation. Henderson said that as the Amateur Radio Service is a secondary user on the 70 cm band, It is important for amateurs to remember that it is 100 percent our responsibility to eliminate harmful interference to the primary user. While we realize that this is and will continue to be an ongoing process, this third round of mitigation should mean that each of the known repeaters in the affected area have been tested at least once. How the FCC will address approximately 50 repeaters previously identified as interference contributors -- but which have not apparently completed the required modifications -- still remains. Nor is it clear when a process by which new coordinations can be issued in the area might commence. Henderson reminded amateurs that It is important to remember that this isn't a one-time solution. The amateur community needs to remain aware of this problem and responsibly utilize the band in the future to avoid any large-scale problems such as those we have experienced in this situation. /EX No virus found in this incoming message.
