This was not a pretty picture since there was no way to achive vertical seperation and transmitter combiners/receiver multicouplers were not as popular as they are today. An intermod study weas run on the site and at either the 5th or 7th order, every receiver on the site should have been experiencing intermod from a combination of all the transmitters. Of course this was not the case. It was just the program spitting out all the possible combinations that COULD cause a problem. All intermod programs just do the mathmatical combinations and report the outcomes, even outragous ones that are not likely to naturally occur. Some do a better job than others of taking into account things like receiver bandwidth and other factors. Actually finding the source where the mix is taking place much more difficult. The benefit of such programs is that they can easily do the math for you, but you have to decide which numbers are good possibilities and which ones are red herrings.

Ok so I plug that into the mix of xmiters in the software and bingo. A+B-C 146.70 + 146.70 - 147.30 = 146.100. The repeater 146.70 does have a circulator. Again this intermod is not my best area. I had the repeater owner keep the 146.700 xmitter up them had him hit the 147.30 with an HT and yep we got a burp of noise. But he heard at least 3 repeaters come up. So if this mix is the one that is causing all the issues, now we just need to find where the mix is occurring. Any ideas on where to look? As you can see in the full printout from the intermod tool.

They are VERY disappointed that they won't be able get their news from channel 4 once DTV has gone into full effect. (They DO have one of the areas BEST news teams - in my opinion.) The center of the map says it all IMO: A4 - D51. Would be nice if they backfilled ch. 4 after the cutover, but I think the channel #s on the map indicate the final assignment. I'm wondering if a dedicated UHF panel and good UHF only preamp will help the situation. I think all you can do is go for max. gain @ ch. 51 hope the problem isn't multipath; if it is you're SOL unless you go WAY up in the air with the antenna. Stacked Yagis might get the job done @ ch. 51, but then you'd need another antenna for the other channels. Don't know if a parabolic would be broadband enough - depends on the type of feed if the aperture (diameter) is large enough to work reasonably at the lowest DTV channel. Bob NO6B Yahoo!

This is one of the toughest intermod products to solve. 2 transmitters 600 kHz apart generate spurs every 600 kHz on both sides of each transmitter. When we were co-ordinating repeaters, it's one parameter we always looked at, and tried to keep nearby repeaters off of that 600 KHZ separation boundary. Are Both repeaters having problems or just yours? These signals don't even have to be generated in your equipment, I've seen them generated by stuff externally and if you look at a spectrum analyzer when both transmitters are on the air, you'll see the Christmas tree like display showing the spikes every 600 kHz decreasing with amplitude as they get farther away. Most suggestions made may help and all I can say is good luck, the only real way out of this problem may be a frequency change for one or the other machine.] Gary - K7NEY - Original Message - From: wa5luy To: Repeater-Builder@yahoogroups.com Sent: Sunday, February 15, 2009 6:15 AM Subject: [Repeater-Builder] Re: Help with intermod between repeaters. Thanks to all for your replies. Joe M wrote You need to reject the opposite TX on each repeater. Your BP filters were set wrong. You rejected the RX on the TX side - something the duplexer should be doing already. You need to install them in the repeater and reject the other TX. IOW, install a filter in the .16 repeater and notch the .36 TX. A good duplexer should do this as well, but many don't. Joe that's what I thought I did. Maybe I did not make myself clear. I put a BPBR cavity rejecting 146.76 and passing 147.36 between the repeater transmitter and the duplexer at the 147.36 repeater. This is where I was surprised that the mixing got worse. If I put the cavity in the wrong place let me know. Eric Lemmon WB6FLY wrote The first question that enters my mind is, were both Micor stations originally built as repeaters, with the extra filters and shielding plates,or are one or both base stations that have been converted to repeaters? I built our repeater. It's the 146.76 machine. It was originally a pager TX. All shielding and the lo pass TX filter is in place. I have looked at it with a spectrum analyzer and see no other signal than 146.76. I have no idea as to what the other repeater was made from. I will take a second look at their TX. The next time I go down there I plan to take a 50 watt radio and connect it to their duplexer to try to eliminate or prove their PA has a problem. The second question is, are either or both repeaters equipped with ferrite isolators? The 146.76 has no isolator. The 147.36 has a brand new, I believe Sinclair, isolator that was factory built for this frequency. The isolator has no affect on the problem although I don't think it's installed properly. I did not notice when I was there but I think it's mounted on a steel plate. Also there in no cavity between it and the duplexer. The mixing is there with or without the isolator in line. They paid big bucks thinking this would fix the problem. By the way they also replaced their antenna and feed line which may have made the mixing worse. John wrote I hate to tell you, a definite way to eliminate the problem, is a frequency change so that the output of the two transmitters are no longer not 600 khz apart. Funny that`s the first thing I told them. I am familiar with two pagers 600 khz apart and the havoc that can be raised. I plan to go back down there when I have time and let the group know what I find.

Central Standard Time, [EMAIL PROTECTED] com writes: Albert, I've had friends joke about MFJ standing for mighty fine junk, but I have nothing but good things to say about my MFJ 259 antenna analyzer. If you're building antennas, the MFJ 259 (HF/VHF) or 269 (HF/VHF/UHF) are really handy. If you're trying to find the resonant frequency or set up a gamma match, they'll save a ton of time compared to an SWR bridge/transmitter combination, and give you more information, such as resistance and reactance displayed separately on the LCD. It also serves as a counter and, in a pinch, as a (not-very-stable and somewhat microphonic) signal generator. But remember the limitations. You can't transmit through them, so they can't be used to monitor the behavior of an antenna under operating conditions. They can't be used to measure a transmitter' s output power like most SWR bridges. They're also prone to error in any environment where strong external signals from nearby transmitters overwhelm the test signal internally generated by the analyzer, which results in a false reading of reflected power. I would recommend these little boxes to anyone, but do have one major complaint - the internal battery scheme. The thing takes 10 AA cells, they don't last long, and you have to remove several screws and the case to change them. You have to be really careful how you transport the 259, because the power button sticks out where any bump will turn it on, and run your batteries down. After having the power bumped on during storage and a resulting leak of the alkalines after they ran down, I cleaned it up (no permanent damage) and just don't put batteries in mine any more. I use it on the AC adapter, a cigarette lighter cord, or an external battery pack, all plugged into the 15V input.

Thorodin, Colorado. A full D-STAR stack of repeaters consisting of VHF, UHF, 1.2 DV and 1.2 DD are now operating from approximately 10,482 feet above sea level. http://maps.google.com/maps?f=qhl=engeocode=q=Mt.+Thorodinsll=37.0625,-95.677068sspn=49.176833,83.320312ie=UTF8ll=39.888665,-105.424805spn=3.000878,5.20752t=pz=8iwloc=addr As of about 10:00 Mountain Time today, our Gateway is back online, and the stack is operating very well. VHF is still slightly deaf due to some site noise, but a new antenna installed today is helping significantly. Most activity is on Port B (UHF 446.9625-) and you can say hello via our Gateway callsign W0CDS. Whiskey Zero Colorado D-Star! The repeater system covers the entire Front-Range area of Colorado, including the Denver Metro area, Boulder, Greeley, Ft. Collins, Castle Rock, Aurora, etc. A quickly calculated estimate was that the stack will have a coverage area of something close to the size of the entire state of Connecticut. Reports already indicate that coverage extends into downtown Cheyenne, Wyoming for mobile users with good antennas, and the surrounding plains out I-76 toward Nebraska, and I-70 to approximately Limon, CO, almost to Western Kansas. We also have reports that HT users are using the system well as into the southeastern and southern suburbs and further south. Coverage generally ends due to the natural RF barrier at the Palmer Divide between Denver, CO and Colorado Springs, CO. Mountain-West coverage has not yet been determined. We will know more as we get signal reports from far-flung hams using D-STAR. We welcome signal reports, see our contact page: http://www.coloradodstar.org/contact.htm A coverage map from another group's VHF repeater is here: http://www.colcon.org/fig/thorodin_coverage.gif A 3D map of the mountain is here from the same group: http://www.colcon.org/fig/mt_thorodin_3d.jpg Here's a photo of the mountain from northwest of Boulder, CO: http://www.colcon.org/fig/mt_thorodin_big.jpg (Thank you to the Colorado Connection for use of their graphics.)

According to the schematic, the anodes (the ends with the arrows) are connected to the case and ground. Push-in diodes came both ways, mainly because many alternators use three of each inside, and they can only ground the case of three of them.

The number on the backplane does NOT match - but don't ask me what it is, because I'm at work and can't get to the station right now. I should be home by 3PM CDT, so I can post it then if necessary. I do know these were repeater station originally, not paging stations. So how do I go about getting the proper documentation? I'm pretty sure the manuals are all out of print by now... (I do have the orange book - Applications Manual, I think - as well as the manuals for both the low and high power stations.) However, the orange book does not show all the modules I have - I know it doesn't cover the 4-User Control Module, and maybe not the Master Decoder either... I have several versions of the Station Control, Squelch Gate and Time Out Timer modules - some schematics for the newer revisions are not shown in the manual either. Mark - N9WYS -Original Message- From: Repeater-Builder@yahoogroups.com On Behalf Of Jeff DePolo I know these stations have jumpers all over the place - backplane, cards, etc. - that all needed to be configured properly for the thing to work the way it should. I have the manuals, but I am stumped. I know I'm missing something, SOMEWHERE - my problem is: WHAT and WHERE? Could be quite a few reasons why you don't have repeat audio. Start at the receiver and work your way forward, using the chart for the unified chassis and the module schematics in the orange book to help you follow the repeat audio path through the station. Besides, the manual's diagram for the backplane shows jumpers numbered in a certain sequence and the backplane I have has them numbered differently - they're in the same locations, but numbered differently. You sure you have a standard backplane? There were a number of varients, one of the more common being the backplanes that were used for Micor PURC (paging) stations. Check the part number stamped on the backplane board for the unified chassis and make sure it matches what you have documentation for. --- Jeff WN3A Yahoo!

If the audio/squelch board has been modified for and squelch and the interconnct board changes have not been made, you will have repeat audio in PL Disable or carrier squelch mode and no repeat audio in PL Mode. Not sure if that is your problem, but it is one of the many things that will cause no repeat audio in the PL Enable Mode with a Micor station. I do not have my manuals in front of me, but this information is in the supplement for the station chassis that covers the backplane and the accessory cards. As was also suggested the Community Repeater manual will be your best friend, if you are going to be running the station in that configuration, as there are several differences between a standard repeater configuration and the community repeater configuration. If everything is properly configured the 4 user PL card should do both PL tone decode and encode. If you have trouble finding the information let em know and I can dig out my manual when I am in the shop tomorrow. Good luck with your project. Joe - WA7JAW No virus found in this incoming message.

The program, Tower Dogs, will air on Monday, July 21 at 10:00 PM/ET. The hour-long broadcast is expected to give an up close and personal no-holds-barred look at tower dogs' lives - up in the air and on the ground. We experience their on-the-job tension and watch them work hard, play hard, and mourn when they lose one of their own, NBC said in a press release. In a twist on all the dangerous-job programs that solely feature males, typically narrated with muscular prose, Tower Dogs follows an unusual tower crew boss: a woman named Nikki Collins, a single mom, former cheerleader, and the person keeping her tough-guy charges in one piece. Although there has been a noted increase in tower construction company owners and climbers that are women they are in a small minority in a predominately male profession. (http://www.wirelessestimator.com/t_content.cfm?pagename=Women Climbers), The Dateline team worked for four months documenting this group of tower climbers as they worked their way through 40 towns and cities in 24 states. During this time there were seven fatalities nationwide, including five deaths in a 12-day period in April. National exposure long overdue, say many.

I would think one could get 15 amps due to the breaker able to handle it or are 15 amp breakers designed to trip at just above 12 amps??? 73, ron, n9ee/r From: Eric Lemmon [EMAIL PROTECTED] Date: 2008/07/17 Thu PM 11:00:53 EDT To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Re: RadioShack Recalls Power Supplies Wayne, That is not exactly true. An outlet rated at 15 amperes cannot have any load greater than 12 amperes plugged into it. An outlet rated at 20 amperes cannot have any load greater than 16 amperes plugged into it. This is clearly stated in Article 210.21(B)(2) of the National Electrical Code. A device that actually draws 20 amperes at 120 VAC must be plugged into an outlet and branch circuit rated at 30 amperes. When load currents exceed 16 amperes at 120 VAC, it's time to consider a branch circuit rated at 208 or 240 VAC. Most repeaters and high-power PAs have optional connections to enable operation on 208 or 240 VAC. Keep in mind that there is no such voltage as 220 although that obsolete figure is still in common usage. The nominal single-phase voltage supplied to residences is 120/240 VAC, while the electrical supply to light commercial, apartment complexes, and condos is usually 120/208 VAC derived from two phases of a three-phase distribution system. I mention this because a fellow Ham who now lives in a large apartment complex mentioned to me that his 500 watt rig that worked fine in his former home was not putting out full power at his new location. The cause was revealed when he measured his line-to-line voltage as close to 208 VAC. His power amplifier was rated for 240 VAC, but was starving when fed 87% of its design voltage. A commercially-available boost transformer was installed to give him a true 240 VAC supply. Problem solved. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Wayne Sent: Thursday, July 17, 2008 11:01 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: RadioShack Recalls Power Supplies To properly plug in an item that is a 20 amp draw. etc., one should install a 20 amp outlet. This can be single or duplex, and is readily spotted (if dual purpose) by the fact that one side will be flat instead of vertical, or have both horizontal and vertical on that side. the flat/horizontal is on the neutral side. Not to be confused with a similar looking outlet for 250 volts, which has two flats , and one has vertical as well on the left side, looking at the front with the ground hole down. Anyway, there are oulets made for 20 or more amps, which are different than the 15 amp common outlets. local ordinances can often be more stringent than even the NEC codes. of course, if you are running a high power repeater, you would probably wish to put it on a circuit breaker by itself. But ordinary house wiring normally has several outlets wired in series from one breaker, and is NEC approved that way. Shop and Industrial become another matter, ha ha ha...

However, theoretically, each outlet could have A 20 amp load plugged into it.That is probably why some pencil pusher decided each outlet needs its own wire. (Never mind the fact the breaker would trip regardless of what is plugged into each outlet or the number of wires leading to said outlets, but that's another crazy thread) As for the Breaker Box, I would assume each also has its own breaker.

At a glance, it almost looked like GE Prog line strips, but thinking, they are a bit wider strips. All tube of course, and most likely still has the crystals set up on the fire frequency (154.3XX). Unknown whether it is working or not. Vintage maybe from the Twin V days? The person who showed it to me seemed to think it was worth some money, but to me it would only be good for the cabinet. Someone would have to make an offer, and maybe pick it up. I'd bet it weighs over 400 pounds? There are also what looked to me like GE prog line units, possibly AC powered, some had the control unit on the front. plus a number of other radios sitting there. the only one that looked interesting to me is a mastr II mobile, 110 watt 66 split, unknown operating condition. May or may not have cable and head with it. I'll try to find out more later. I dare say the base and prog line units are wide band compared to what we use now These are in Imperial texas, which is a 60 mile drive from Odessa, 30 from Monahans or Fort Stockton I'm not as familiar with the older Motorola equipment, but being as it is all tube, as are the Prog lines, it might or might not be of interest to someone on the group.

well, as has been commented, if it was not ordered with down-tilt, there will be none at any freqency you put into it, as all elements are exactly in-phase since the method of acheiving down-tilt was to make the feeds to the lower elements shorter, if it originall had down-tilt I'd venture that the down-tilt would decrease with decreasing frequency (less phase difference) I think.

Ron and all; I wouldn't call it 'don't want the responsibility' so much as 'stretched so thin with limited personnel running multiple stations that it's not possible'. When we end up with 2-3 people running a 'cluster 'of anywhere from 4-7 stations, there simply is not enough time between recording commercials, entering new music into the systems, cutting 'voice tracks', answering the phone, and so on; to deal with what can become a very time-consuming problem. Most broadcasters that I know, especially those of us that started out back in the late 60's-early 70's, remember how important it was to our listeners to get emergency information on the air as quickly as possible back in 'the old days'. Most stations had a 'Weather Plan', stationing personnel in spots to look for approaching storms, and reporting back by land-line phone or Remote Pick-up frequencies. These days, Big Corporate Radio has consolidated studios and cut personnel to where that kind of committment is no longer possible.

John - Original Message - From: n9wys To: Repeater-Builder@yahoogroups.com Sent: Saturday, May 31, 2008 11:13 AM Subject: [Repeater-Builder] Micor Unified Chassis I acquired a number of UHF Micor unified chassis stations, with the intention of converting at least one to GMRS duty. They are in numerous states of disassembly - some are complete chassis less the cards, other have had modules removed, etc. I did get a box of various station cards and at least two known-good PAs to go with the stations, but no power supplies. What I am looking for is a source for the manuals so I can start to reassemble and get at least one going again. I did check at Motorola Parts Online and found what I expected - no longer available. Anyone out there that can help? I see a set available on eBay right now (Item number: 160245704578) - do they cover the unified chassis stations? If so, maybe I'll bid! Thanks!

Re: [Repeater-Builder] Micor Unified Chassis
yes the 'Control and Application' is the one you really need but the others will be useful in the long run examine the rear of the back-plane of the control shelf carefully for factory mods before you start; if there is anything 'SP' about it, that's usually where you will find it, in the form of cut traces and jumpers good luck Gary in IL - Original Message - From: n9wys To: Repeater-Builder@yahoogroups.com Sent: Saturday, May 31, 2008 10:13 AM Subject: [Repeater-Builder] Micor Unified Chassis I acquired a number of UHF Micor unified chassis stations, with the intention of converting at least one to GMRS duty.
