Re: [Repeater-Builder] active low COR
Scott, A while back there was a thread on this subject and one of the members posted the reply below. It really made a lot of sense and I saved it in my archives for future reference. Don, KD9PT Lastly, if you can do it, run your logic level signals as active low, for two reasons: 1) they are much easier to debug, 2) a blown fuse doesn't create a false signal. In addition I prefer to run the interfacing between radio and the controller as open collector since most controllers have their own internal pull-up resistors, and a open collector output is therefore universal - it will work with a five volt logic system, a +12 volt logic system, a relay, a LED (for testing), or anything else, and all with no modifications. Active low signals are easy to debug, and easy to interface - with proper design and component selection you can treat them as if they were a relay contact that goes to ground when active. With an active low environment when the signal is inactive, the transistor is switched off, the collector floats and is dragged high by the pullup resistor. When the signal is active the open collector is pulled to ground. As mentioned above, if you leave the input open (for example unplugging the cable between the control receiver and the controller) the pull-up resistor causes the input to go high. If you program the input for active low and unplug the cable it doesn't care. Personally, because of the above reasons, I dislike active high. I recommend that first you program your repeater controller COR, PL and logic inputs to be active low, and add a transistor inverter to your hardware if necessary. Another benefit of active low interfacing is if a radio loses power or otherwise fails, the pull-up resistor in the controller doesn't "pull up" the dead signal to a false active, resulting in the system being keyed until the timeout timer disables the system transmitter (you DO have a separate backup timeout timer, don't you?), thereby rendering the entire system unusable. Also when you are working on the system you can do a large amount of testing with nothing more than a clip lead shorting the open collector outputs to ground without worrying that you're going to blow something up (picture a site visit some day... PL decode not working? ground the PL decode lead and see if the PL indicator on the controller front panel lights up. yes? the problem's gotta be in the decoder itself inside the receiver chassis!). Also with open collector interfacing you can shut off the system, disconnect or un-cable the bad radio/device/etc. and then turn the system power back on and everything else in the system still works because the pullup resistor in the unplugged open circuit looks like an idle signal... - Original Message - From: scott w To: Repeater-Builder@yahoogroups.com Sent: Thursday, June 03, 2010 3:55 AM Subject: [Repeater-Builder] active low COR Hello to group, What is the advantage of an active low COR. Most I have talked to say they have their controllers set that way, so I set mine that way,plus the Maxtrac I am using as a receiver default is active low. I simulated a power failure to the reciever and the line went low and the transmitter thought it was time to transmit. I also accidently pulled the cord from the controller off the back of the receiver and again a low status and the transmitter thought it was time to transmit. Im not seeing a benefit of a active low COR in those repects. Should I go to active high or since those things dont usually happen often leave it LOW.. Any advice or ideas appreciated.. 73s

[Repeater-Builder] Fw: (PWF) The FCC's Consolidated Licensing System
All, Very rarely do I cross post a message from one group to another. I'm a member of the Private Wireless Forum (PWF) since I have dealings with the commercial LMR industry as well as the FCC. The FCC is proposing consolidating it's licensing system into one database. Whether that happens or not, it still involves the hams to a certain extent. Most of you receiving this email will disregard it, since the vast majority of the list members are hams just using the spectrum as their personal hobby. However, since the list is so huge it also encompasses members who are actively involved in commercial entities. And not to mention those hams who will renew their licenses in the future. Please read the message below that was posted on the PWF forum. Thank you. Don, KD9PT Subject: (PWF) The FCC's Consolidated Licensing System Nobody has mentioned the FCC's proposed Consolidated Licensing System. This is going to change the way licenses and antenna structure registrations get done. All those separate systems and forms are going to merge into one big system. And the forms and data required on applications may change significantly. They had a workshop recently where representatives of law firms, engineering firms, associations of licensees, etc. gave brief descriptions of how they use the current licensing systems and how they'd like to see the systems changed. Interesting stuff... sorta. You can watch the workshop (all 3 hours of it!) at reboot.FCC.gov under the Events tab. I have a LOT of things I'd like changed in the way licenses are handled. For instance: you can only renew an STA in the 10 days prior to its expiration date even though the license shows up 90 days in advance of the expiration date in your FRN renewal list. That's just the tiniest tip of the iceberg. The FCC says they are looking for input on ways to make things easier, faster, whatever. If you let somebody else handle all your FCC paperwork you probably don't care. But if you get your hands into the FCC's systems, you may want to pay attention to what's going on.

[Repeater-Builder] OT:Antenna height restrictions and PRB-1
Hi group, First off, hopefully this post is not going to conflict with Kevin's restrictions on the FCC rules & regs on this forum. I'm looking for some information from others, that in the past, have had situations with local / county / state governments concerning antenna height and what their outcomes were. There's a situation right now in southeastern Wisconsin where a 10 year old ham is having issues with neighbors and the local government about his tower height. You can read the full story here: http://www.todaystmj4.com/news/local/91663619.html Specifically I'm looking for any situation that happened in the past with you and your government that you had and how it was resolved, both bad and good. Kevin, if this conflicts with your rules then please direct the membership to my private email, dkupfers sbcglobal dot net. TIA in advance to all that respond. Don, KD9PT
Re: [Repeater-Builder] Sinclair C-Series cable lengths
Jeff, Speaking of the RLB, did you ever get one of the newer RLB's from Amtronix? I still interested in someone measuring the parameters of that unit against one of the more expensive RLB's, such as the Eagle brand. If the measurements are fairly close to each other, then the Amtronix RLB would be a good unit to have, especially for the price that he's asking. Also, your post below was really good information to have. Thanks! 73, Don, KD9PT - Original Message - From: Jeff DePolo To: Repeater-Builder@yahoogroups.com Sent: Tuesday, April 20, 2010 5:46 PM Subject: RE: [Repeater-Builder] Sinclair C-Series cable lengths > I adjusted the loop positions, trying to maintain symmetry of > the curve, aiming for 1 db > on the analyzer. I didn't adjust the loops while looking at > the RL. How would I translate RL > into IL? You can't directly translate from RL to IL or vice-versa. Here's how to tune a pass cavity: 1. Ballpark the insertion loss using the stickers on the loops and/or by measuring the insertion loss at whatever frequency the cavity is presently tuned to. 2. Rough-tune the cavity to something near your desired frequency. Don't bother being too critical here - the resonant frequency is going to wander a bit as you adjust the loops in the following steps. 3. Terminate one cavity port with a high-quality 50 ohm load (high quality: >= 30 dB return loss). Connect your RLB to your SA/TG, with the DUT port connected to the other port on the cavity. You *must* use a cable between the DUT port and the cavity that is known to have excellent return loss! The cables between the SA/TG and RLB should be good quality, but are nowhere near as critical as the cable between the RLB and the device under test. 4. While measuring the return loss, make minor adjustments to one of the loops to maximize the return loss. Again, ignore the frequency of the return loss "dip", it's going to vary slightly as you adjust the loop, just go for maximum return loss at whatever frequency the dip happens to fall at. Keep the screws snugged down well on the loop assembly; if it's not sitting tight and flush in the top of the cavity the tuning will change when you go to tighten the screws later. There's a little chicken-and-egg here; you have to loosen the screws to adjust the loop, but when you tighten them it's going to change it a bit, so you have to emperically find the sweet spot. With most cavities, you should have no problem getting well in excess of 20 dB return loss - shoot for 30 dB if you can, even though at that point uncertainty due to the test equipment's limitations will be dominating the measurement accuracy. 5. Reverse the connections you set up in #2 above. Check to make sure the return loss is still high looking into the other port (it should be). 6. NOW, adjust the resonant frequency using the rod to put the return loss maxima it where you want it (i.e. at your pass frequency). Assuming the cavity was rough-tuned in step #2 above, the return loss should not change as you fine-tune the resonant frequency. 7. THEN, check the insertion loss through the cavity using the SA/TG. It should be fairly close to what you set it to in #1 above; if it's more/less than what you'd like, adjust ONE loop for more/less insertion loss, and then repeat again from step #3. DO NOT adjust the resonant frequency via the tuning rod during this step!!! Unless the cavity was poorly designed, tuned, or handled, the return loss maximum should align very closely with the insertion loss minimum. Once you've properly tuned the cavities individually, then cable them together and re-check return loss and insertion loss. Report back how it goes and what numbers you come up with. --- Jeff WN3A

[Repeater-Builder] Controller order PayPal problems
I have been burned by PayPal several times. The real reason they put the "hold" on your checks or "hold" money owed to you has nothing to do with your ratings and little to do with security. Basically, they control billions of dollars in transactions ever month through EBay. By "holding" the money even a few days (typically 2 to 4 weeks), PayPal makes millions in free interest on your money (your interest, actually). There is little regulation in the industry and since EBay owns PayPal, they can pretty much do as they please with your money and you can just lump it. I'm a capitalist and I hate unnecessary government regulation and any form of socialism. However, I don't see any change soon as these guys are cozy with legislators.

Hello again Ian
I've also tried a decoder with a 4 MHz crystal and it still heterodyned.
Get a tunable decoder and your troubles will be solved.
What I found was if I turned up the TX CTCSS encode, the decoder
activated and held up the receiver which held up the transmitter etc.
We also had a ~ 1KHz whistle, probably the receive signals or TX were
off frequency by that much.
Peter VK2ZTV also has had the same problem with FM-828's

Hello Ian
IF your repeater is a UHF and the CTCSS decoder has a 5 MHz
crystal oscillator, it will mix with the transmitter and give a signal at the
receiver frequency 5 MHz lower (in Australia RX 433-435 TX 438-440 MHz)
This a is a common occurrence with UHF Philips FM-828's.
The fix is to use a tuneable CTCSS decoder and not use the one
with a crystal oscillator in it.
Been there and done that. Took years to find out why we had a
whistle in the receiver (heterodyne).

Hi guys .I was looking at adapting a midian tds-1 to a
maxon pm150 but we end up with feedback problems when used in repeater .
Can anyone suggest ideas to give rf protection to the
decoder chip .I came up with shielded cable between the board and the chip
And to install the chip in a metal case on near the radio
.or mounting it as close to the rf motherboard as possible but I don't think
It will fit under the lid .The reason we would like to use
the tds-1 is that the radio has to unmute before it decodes
And I would like it to decode before the signal opens the
mute .This improves the speed the repeater opening up
On a valid signal .

Troubleshooting and repairing it is the easy part - locating the needed component is the hard part! IFR is of no help, only wanting to sell a new $1k++ power supply assemnbly, or repair the whole monitor for big bucks. The problem has been traced to a failed VICOR VI-262-EU dc-dc converter module. Basically, the power supply is designed around two key Vicor modules - First, a Vicor AIM module which takes 100-240vAC input and converts it to 300vDC. This 300vDC is then fed into a Vicor VI-262-EU DC-DC converter, which supplies 15vDC @ 200w (13a) to the rest of the custom IFR supply. This 15v output is then fed to a relay network which selects between the converted AC supply, the internal battery (if so equipped), or finally an external +12vdc via a Powerpole jack. From the number of IFR power supply failures I have heard of (or have seen on Ebay listings) this is a common failure mode. Fortunately, the monitors still work when fed via the 12vDC input (which basically bypasses the two aforementioned modules). I have tried to purchase the module without much luck. Vicor will sell direct, but has a long lead time, as the part is made to order. I have found a number of equipment brokers who will quote quantity purchases, but no single units. Plus, their "fees" are exhorbinent for a single unit purchase. Anyone have any surplus Vicor VI-262-EU modules lying around? Another option is to purchase a quantity of them. Anyone interested in purchasing spares for their IFR units? Eric K2WD

Re: [Repeater-Builder] Question on portable repeaters
When I was in college and had a part time job in the summer for a local radio station, we did many remotes using the 150 Mhz range. We had Marti broadcast equipment. Being in northern Wisconsin, it was challenging at times to go out to a resort in the Nicolet National forest and try to get a good signal back to the station. I'll never forget the day that I had to climb up an evergreen tree and hang the antenna up around 75 feet before the station got a good signal. The station manager told me later that "if you didn't do that remote, you wouldn't be working here anymore". BTW, that's how I got into ham radio.

[Repeater-Builder] Re: coax cable
The commercial companies have literally unlimited monetary resources when putting up a system. You do it once, you do it right, and you don't spare the money. The smart broadcast companies don't fool around. They know better. You short change on anything, and you pay the price down the road. I've seen that happen, and I've had to clean up the previous engineer's mess. Not a pretty sight. You can't compare that to an amateur setting with limited money. Connecting Heliax to an antenna directly in amateur use is just plan senseless. A jumper works pretty much every time, especially if it's done correctly. You can certainly make the point that other cables are cheaper up front. I don't see how "connecting Heliax to an antenna directly in amateur use is just plain senseless." It makes very good sense. I have seen plenty of jumpers used at height that worked fine for many years. The loss in the additional connectors and the smaller jumper cable is truly negligible. Using a jumper isn't necessarily wrong, it just isn't necessary.

Re: [Repeater-Builder] Tower Foundations
Ask the consulting engineer if re-bar could be added near the inside perimeter to the cement base to reinforce the foundation. I did this years ago when I installed a Rohn tower in a sand ground circa 1977 in northern Wisconsin. I never had any problems with the base moving around going forward ever since. That tower is extremely solid; not one of the antenna installers ever had an issue climbing it. One of the other things that we did was to pound 3 - 10 foot metal pipes in a triangular shape below the base ground level and leaving about 3 feet above it to bond with he concrete. Hope this helps. Good luck with your project. 73's, Don, KD9PT - Original Message - From: Barry To: repeater-builder@yahoogroups.com Sent: Sunday, September 13, 2009 4:44 PM Subject: RE: [Repeater-Builder] Tower Foundations I did some courses about this decades ago and remember very little but by adding some side excursion I remember something about a quadripling effect .. don't quote me of course as your consulting engineer can better answer this but certainly well worth it . -- To: Repeater-Builder@yahoogroups.com From: mafl...@att.net Date: Sun, 13 Sep 2009 15:42:46 + Subject: [Repeater-Builder] Tower Foundations One of my family members is putting up a tower to support his business radio (farm) , the family GMRS repeater, and a fairly large microwave dish to obtain internet.

Re: [Repeater-Builder] Passive fer wifi
We had the same situation here in Wisconsin. AT&T put in a fiber optic network, so I went with it. I used a Linksys router, model WRT54G (2.4Ghz 802.11g) in conjunction with it and placed it in the attic of the house. I've got laptop coverage for over a 1/4 of a mile here in the sub division. Works really well, plus you can password protect the connection so only you have use to it. If your daughter doesn't have a wireless laptop you can buy an internet adapter that allows desktops and other systems to receive the WI-FI. You can buy these routers for < $100.00 almost anywhere.

Art was proprietor of Spectronics Inc of Oak Park, IL for many years during the 1970s! He sold used Motorola gear to hams in those early days of amateur repeater development Arthur E. Housholder a longtime resident of Elk Grove Village A memorial service for Arthur E. Housholder, 82, will be held at 10 a.m. Saturday, July 11, at St. Michael the Archangel Cemetery, Palatine. Mr. Housholder passed away Tuesday, July 7, 2009, at Alexian Brothers Medical Center. Art Housholder, like a select few of the kids of his generation, was bitten by the amateur radio bug, and became seriously infected at K9RTG. And what could be more fun than running a ham radio store* In the late 1960s his store, Spectronics, was a Chicago center for a new amateur radio technology called repeaters ... a technology that would help change the whole world as cell phones ... bringing personal communications to over two billion people. Amateurs, frustrated by the limited line-of-sight range of their little hand-talkies, began putting automatic relaying stations atop tall buildings and mountains, giving them a hundred or more miles range instead of a mile or two. And Art was one of the leaders of the revolution by using his close contacts with Motorola to convince them to pioneer the cell phone industry, where they are still a major player. He was also awarded as a member of the Circumnavigators Club, an exclusive international organization open only to people who have voyaged around the world, crossing every meridian, in a single trip. Members include the likes of Neil Armstrong, Sally Ride and Walter L. Cronkite. He was the beloved husband of Ada; loving father of Anne Marie, Ann Cristine, Bob/Mary, Steve/Faye Marie and Gary/Mary; proud grandfather of Matt, Mark, Julie, Andy and Katrina; great-grandfather of Hunter, Brook and Kira; fond brother of Alice O'Day; and close friend of Wayne Green, Dick McKay, Frank Mercurio and Dave Zatler.

[Repeater-Builder] Dayton hamfest vs hotels / motels / sleeping arrangements
Hi everyone, I wanted to go to Dayton this year but a death in the immediate family plus my wife's work trip to a distant city precluded this from happening this year. I've been monitoring the posts about Dayton and it seems that there are some of you who are unhappy about their sleeping accommodations while attending the hamfest. Perhaps there should be an informal discussion on who's good to stay at, and who's not so good. I plan to go next year and I'd like to know where there is a good place to stay for a reasonable price.

[Repeater-Builder] OT New U.S. House of Representatives Bill, HR 2160
As Hams being involved in this Type of Communications ,We need to keep an Eye on this Bill 73 De Don KA9QJG Section Summary, April 2009 The text of a new U.S. House of Representatives Bill, HR 2160, is to be found at: http://www.arrl.org/govrelations/HR2160.pdf . This bill, introduced by Texas Rep. Ms. Jackson-Lee, and co-sponsored by other members from disaster prone districts, could end up giving us the data we need to fight unreasonable antenna support structure limitations imposed by land use agents, private and public. In itself, it requires the Department of Homeland Security to conduct a study of unnecessary or unreasonable impediments to the 'deployment of Amateur Radio emergency and disaster relief communications'. The strong wording of the bill reflects the positive impression made by ham radio EMCOMM operations in Texas witnessed by Ms. Jackson-Lee. While we should not rely completely on the bill to do everything for us, it may at some time be the impetus for the end of unreasonable antenna restrictions. After you read the text of the bill, request your congressman to co-sponsor this important piece of legislation

As a moderator one of the things I do daily is log into the group and check for pending messages and pending members. Well, when I got home at 0117 on Tuesday (after the semi-annual sheriffs communications reserve meeting, plus the post-meeting critique at the local Dennys) I went to check for pending messages before crawling into bed and found that we've hit 4402 members (not counting the 251 on the banned list). I had planned on making this announcement at 4,000 but real life got in the way - and by the time I was able to check the count was at 4428. So I was waiting for 4400. So... here's a few things that struck me as interesting... Of those 4402, 700 (exactly!) are in daily digest mode, 1096 are getting individual emails, 2163 are in "No Email" mode (which means they read it at the yahoogroups web site - hopefully they DO read it) and 441 are in "Special Notices" mode (which is just like the "No Email" mode except that they would receive an email if the moderators or the owner needed to send out a high priority email to all the group members). Personally, I never use "No Email" mode, I always use either "Individual Email" mode or "Special Notices" mode. There have been times when the group owner or a moderator needs to send out a high priority bulletin. Of the 4402 current members there are 131 that get their mail via arrl.net, which surprises me as my arrl.net address (I've been a life member since 1978) consistently black-holes about 20-25% of the mail sent to me by way of arrl.net. A closer look shows that only 20 (exactly) are on individual email mode, and 22 are on daily digest. The rest are in "No Email" or "Special Notices" mode. The oldest member is dated as having joined on the first of January 1999 (which may be an artifact of the Yahoo data base), and 148 are listed as having joined that year, 178 in 2000, 290 in 2001, 316 in 2002, 438 in 2003, 413 in 2004, 579 in 2005, 648 in 2006, 639 in 2007, 576 in 2008, and 175 so far in this year. A few more facts that struck me as interesting are: 214 on gmail 198 on hotmail 29 at juno.com 2 at motorola.com 1 at ge.com none at Ericsson none at tyco none-at com-net 1683 at yahoo (collectively) 37 at yahoo.ca 36 at yahoo.uk 1492 at yahoo.com 6 at yahoo.ar 27 at yahoo.au 7 at yahoo.br 7 at (anything).gov 65 in (anything).au (Australia) 13 at (anything.br (Brasil) 97 at (anything).ca (Canada) 2 at yahoo.com.cn (China) 2 at (anything).hk (Hong Kong) 23 at (anything).it (Italy) 5 in (anything).mx (Mexico) 9 in (anything).nz (New Zeland) 5 at (anything).pt (Portugal) 11 in (anything).se (Sweden) 3 at yahoo.com.tw (Taiwan) 59 at (anything).uk (United Kingdom) 9 at (anything).za (South Africa / Zaire) 1 at (anything).zw (Zimbabwe) The above is not intended to be a full country code list - just the ones that stood out as I wandered through the spreadsheet And no, I will not violate anyone's privacy by releasing that spreadsheet.

Maybe we should ship some of our Califoriadoans (Californians who moved to Colorado in the 90's) out to Albany, NY or something so they can see REAL snow. hahaha. Some "lake effect" dumpage would get their snow-o-meters recalibrated in their heads. Schools closed, shelters open here. Whatever! Bunch'a 4WD driving soccer moms in this town, these days. NWS issuing a Blizzard Warning for the metro Denver area without 3 hours of sustained 35 MPH winds, is almost shameful. This is just a snowstorm. not a blizzard. Sheesh. Wimps. ARES is out running nets for shelters and stuff. I guess it's good practice for 'em. "We're out of donuts, over."

Morris, I'm not even to ask why "the actual installation is in the county jail in a jail cell". I'll bet that's an actual story onto its self. I had an SCR2000A when I started in the ham repeater hobby, but soon realized that it was quite inferior. When I had it, I also re-wired the power supply, as you have, and the machine just sat there and ran. No issues. As far as the receiver goes, well, it's a stretch. It's not mother MOTO or GE, but it gets the job done. I finally got rid of it and acquired a MICOR with a unified chassis. Best money I've ever spent. Worth every dollar.

In Oregon, I had Comcast VoIP, which I was assured was backed up for power outages. Sure enough, power went out in a windstorm, and the little UPS included with my modem kept it running, but the network itself was down. When the power came back on, so did the network. My neighbors with Verizon POTS service never lost it. Here in Utah, I work out of a home office, and was experiencing routine outages of both VoIP and internet, usually lasting 20-30 minutes, between midnight and 1am, when I needed both for work. This would happen two or three times a week. It was clearly some kind of routine maintenance, but the Comcast customer service reps (when I reached them on my cellphone) had nothing more useful than their scripts, and of course, "Have you rebooted your router?" Finally, they went down for 30 hours, including most of two business days, this time including phone, internet and TV. They were so arrogant about it when I called that I cancelled all three. I got DTV converter boxes and do without cable TV, got a copper-pair-based landline phone, and my new fiber-optic internet service rocks - it actually delivers its advertised speeds. Comcast never came close to achieving its ad claims. Comcast internet access is a flaky toy, in my experience. The company has a complete lack of "uptime ethic."

FYI One of the original Voices of WWV Passed away Our Thoughts and prayers go out to the Family 73 De Don KA9QJG The recorded voice of Time and Frequency Station WWV has fallen silent. This with word that announcer Don Elliot Heald, of Atlanta, Georgia, who gave WWV its human touch passed away on Thursday, February 19th. Known in the broadcast world as Don Elliot, Heald had distinguished career that ranged from work at Atlanta Georgia's WSB to his automated and internationally heard WWV broadcasts on shortwave. He was also the voice of the Audichron telephone dial-in Time-Weather-Temperature service and of the Protestant Hour radio show for over 40 years. For nearly five decades Heald narrated the televised Christmas Eve service from Atlanta's Episcopal Cathedral of St. Philip, where he served as a vestryman, junior warden and senior warden. Heald was originally from Massachusetts, but came to Atlanta via Lakeland, Florida. He was a graduate of the University of Florida at Gainesville and began his broadcast career after graduation when he accepted a position at WRUF where remained for three years. In Atlanta he spent much of his spare time devoted to public service work with charities and civic clubs. A Service of Celebration of Don Elliot Heald's life took place on Tuesday February 24th at the Cathedral of St. Philip. He is survived by his wife Sara Farmer Heald of Atlanta, GA; sons and daughters-in- law David and Deborah of Ponte Vedra Beach, Florida, Tom and Evelyn Heald and Frank and Mary Heald of Atlanta.

Up in Northern Wisconsin we have a ham who is a ham and used to own a business repairing TV's. He's now retired.

The mention was the second item on "page four" of his Paul Harvey Noon News and Comment program: "America's quiet warriors are the legion of ham radio operators, 700,000 of them, who are always at ready for backup duty in emergencies -- amateur, unpaid, uncelebrated, civilian radio operators, during and after floods and fires and tornadoes. After the 9/11 attacks, hams were indispensable in reuniting friends and families. Most recently it was they who expedited the search for debris after the disaster to the space shuttle Columbia, and right now, at this moment, they are involved in homeland security to a greater degree than you would want me to make public." The commentary's enigmatic and mysterious final sentence -- typical of Harvey's habit of leaving his listeners hanging -- apparently refers to the fact that many Amateur Radio Emergency Service (ARES) and Radio Amateur Emergency Service (RACES) teams have ramped up their alert status as hostilities get under way in the Middle East. http://en.wikipedia.org/wiki/Paul_Harvey

At one of my repeater sights, I have a 220 repeater, a 440, and a 900. Also, there is a paging transmitter about 3 feet away from all of this. Here's the issue. The paging transmitter is desensing both the 440 and the 900. The 440 repeater is a kenwood tkr850, and the 900 is an msf5000. I'm running a set of 4 cavity wacom cans on UHF, same for 900. The paging transmitter is transmitting on 152.6. We've watched it, and there is no doubt that the paging transmitter is the problem. The transmitter is a Glen Air. We can shoot a weak signal in to the UHF repeateror the 900 with the service monitor. That weak signal will get very strong as soon as the paging transmitter unkeys. We even went to the extreme of getting a filter from par electronics to knotch out the 152.6, but na, didn't work. As if this isn't bad enough, the antennas for the 900 and the 440 are only about 25 feet apart horizontally, it's as far apart as they can go. Any thoughts guys, anyone ever run in to this situation?
