This is why it is always best to order a complete element, rather than to order just the crystal and install it in an element yourself.

Re: [Repeater-Builder] Motorola R100 question
I have done several of these without too much trouble. On the batlabs site there is a hack for the R-100 RSS to allow out of band freq's to be entered. The units I have done have not required any tuning to operate in the ham band, but others report that they have had to. The TX and RX chassis inside the repeater each use a DB-15 connector to connect to the outside world. All the signals you will need to interface an external controller are available on these connectors. Just disconnect the existing connectors and supply and wire your own. Also make returning to the stock configuration possible at some time in the future. However, the RX audio out of the receiver module is not muted by the squelch circuit on this connector. You will need to count on your controller to provide this function. Keep the PA on this machine cool. Probably a good idea to keep a muffin fan blowing across it.

Re: [Repeater-Builder] maxtrac help
A M-120 or GM-300 would be a better choice for your TX radio. Maxtrac radios do not have any PA thermal feedback to the contol board, where the newer radios do. The Maxtrac will have to be fooled into thinking it is a 136-162 MHz radio before the power control circuit will work below 146 MHz. This requires blanking the logic board and re-initializing it as a low-split radio. Another other option is to use a LM-317 and build an adjustable regulator to drive the power control line going to the PA. One other nasty habit the Maxtrac radios have is that when continously keyed for more than about 9 minutes, the controller will run the TX power down, eventually cutting the PA completely off. This feature is built into the radio firmware to protect the PA because there is no monitoring of the PA deck temprature. Using the external regulator gets around this problem also. Hope this info helps. 73, Kevin, K9HX At 08:55 AM 2/4/2006, you wrote: I just bought 2 maxtracs with the intent of making a repeater. Model#D33MJA77A3CK. The radios work ok but they are 146-174Split.

Hi Nate, You have what was called the 2 Watt LPI (low power-industrial) version of the UHF Maxar 80. The model number would indicate that it is a 2- freq radio with tone PL.

Then you will need to pull down slightly on the bottom of the plastic case at the rear of the radio to disengage the two retainer tabs, and slide the chassis out of the case.

Re: [Repeater-Builder] Re: Tuning a MSF5000 UHF repeater
Here is something else to try. This assumes that the PA pre-filter has been tuned to your frequency. With the TX filter bypassed, but everything else hooked up, try turning the power set control down a little. It may be that you are simply driving the PA too hard and it is shutting down. There are two different versions of the high power PA, One with a single circulator, and one with a triple circulator. I don't recall the exact figures, but the ouput of the PA has to be de-rated depending on which circulator arrangement you have. With the triple circulator, the power out of the PA into the TX filter should be in the vicinity of 70-80 watts or so. The manual will have this info in it. As stated by others the TX filter is a real pain to tune, but once set up they work well. The pre-filter is a little easier. Hope this helps, and good luck! 73, Kevin, K9HX At 05:50 PM 11/12/2005, you wrote: Bob M. [EMAIL PROTECTED] wrote: I get the impression that if you HAD a manual, you wouldn't be asking all these questions. Yes I have the manual, however some of it appears to greek to me, but as I ask questions, it makes more sense. Anyway, tuning the internal filter/duplexer is a royal P.I.T.A. The first thing I do is remove the outer skin from the cabinet. This gets you easy access to the connectors on the F/D. The procedure requires a sig gen, an RF voltmeter, and the tuning cable you used with the receiver, however it can be done with a spectrum analyzer that has a tracking generator. You'll also need an accurate, low power, 50 ohm dummy load. I do have a service monitor here to help in the aide of this project. Rather than go through the entire procedure and bore everyone, I'll send you, or post, the couple of pages from my manual. The procedure must be followed exactly. You can't go back and re-adjust the coils. They get done in a particular sequence and if you fool with them again, you won't get the performance that's needed. The VCO drives the intermediate power amp (IPA). This sends 3-9 watts out to the three-coil section of the F/D, and this feeds the input of the power amp (PA). The output of the PA goes into the four-coil section of the F/D, and this feeds the TEE cable that joins the receiver to the antenna connector. These cables are cut for a specific Tx/Rx relationship, and your new freqs must match that. For example, the normal commercial repeater transmits on, say, 460 MHz, and receives on 465 MHz. The fact that it receives higher than it transmits can't be changed when you use the station in the amateur band. Your receiver must still be 5 MHz higher than the transmitter's output. They do make cables for the other direction, but they're extremely rare. There are color bands on the TEE cable that identify the freq range and direction. Hopefully you have the proper cable. If not, either you'll have to try to make one, buy one (they're probably NLA from Motorola), choose another repeater frequency where the offset direction is appropriate, or not use the station at all. I am receiving higher at 447.000 and transmitting at 442.000 The controller samples the IPA and PA output levels and if they aren't within the range they think is normal, you'll get a PA failure error. If the F/D isn't tuned correctly, you'll get too much loss in the system and the sensing circuits will tell you something's wrong. The digital stations will extinguish an LED. If I disconnect the pa, and the F/D, would this not eliminate the problem between the IPA and the F/D?

Re: [Repeater-Builder] Re: Tuning a MSF5000 UHF repeater
The built in duplex filtering option is simply a very high Q pass filter system. Everything on the TX side should be tuned to your TX frequency. The RX side of the filter is actually the receiver front end. which should be tuned to your RX frequency. Since you have a single frequency application, the tune freq will be the same as your operating frequency. The tune up freq applies only to stations that use multi freq TX/RX. A RF millivolter is vastly different from your RS VOM. You could possibly sub a spectrum analyzer for the RF millivoltmeter if you have access to one. 73, Kevin, K9HX At 08:13 AM 11/13/2005, you wrote: Sitting here looking at the tune up procedure for the filter, it tells me to insert a rf millivoltmeter probe into J18 and insert a 225 mV signal into the the output of the post filter.

If you could help me to understand, is the post filter tuning the pass frequency of 447.000 which is the receive of the system, and the prefilter for the 442.000 transmit. Or is the unit simply filtering all of 447.000 to handle the isolation of the transmit frequency. It also says to refer to the Station Parameter Booklet to for the appropriate tuneup frequency, I'm assuming that would be the input of the repeater at 447.000? Kevin Berlen, K9HX [EMAIL PROTECTED] wrote: Here is something else to try. This assumes that the PA pre-filter has been tuned to your frequency. With the TX filter bypassed, but everything else hooked up, try turning the power set control down a little. It may be that you are simply driving the PA too hard and it is shutting down. There are two different versions of the high power PA, One with a single circulator, and one with a triple circulator. I don't recall the exact figures, but the ouput of the PA has to be de-rated depending on which circulator arrangement you have. With the triple circulator, the power out of the PA into the TX filter should be in the vicinity of 70-80 watts or so. The manual will have this info in it. As stated by others the TX filter is a real pain to tune, but once set up they work well. The pre-filter is a little easier. Hope this helps, and good luck! 73, Kevin, K9HX At 05:50 PM 11/12/2005, you wrote: Bob M.

Yes I have the manual, however some of it appears to greek to me, but as I ask questions, it makes more sense. Anyway, tuning the internal filter/duplexer is a royal P.I.T.A. The first thing I do is remove the outer skin from the cabinet. This gets you easy access to the connectors on the F/D. The procedure requires a sig gen, an RF voltmeter, and the tuning cable you used with the receiver, however it can be done with a spectrum analyzer that has a tracking generator. You'll also need an accurate, low power, 50 ohm dummy load. I do have a service monitor here to help in the aide of this project. Rather than go through the entire procedure and bore everyone, I'll send you, or post, the couple of pages from my manual. The procedure must be followed exactly. You can't go back and re-adjust the coils. They get done in a particular sequence and if you fool with them again, you won't get the performance that's needed. The VCO drives the intermediate power amp (IPA). This sends 3-9 watts out to the three-coil section of the F/D, and this feeds the input of the power amp (PA). The output of the PA goes into the four-coil section of the F/D, and this feeds the TEE cable that joins the receiver to the antenna connector. These cables are cut for a specific Tx/Rx relationship, and your new freqs must match that. For example, the normal commercial repeater transmits on, say, 460 MHz, and receives on 465 MHz. The fact that it receives higher than it transmits can't be changed when you use the station in the amateur band. Your receiver must still be 5 MHz higher than the transmitter's output. They do make cables for the other direction, but they're extremely rare. There are color bands on the TEE cable that identify the freq range and direction. Hopefully you have the proper cable. If not, either you'll have to try to make one, buy one (they're probably NLA from Motorola), choose another repeater frequency where the offset direction is appropriate, or not use the station at all. I am receiving higher at 447.000 and transmitting at 442.000 The controller samples the IPA and PA output levels and if they aren't within the range they think is normal, you'll get a PA failure error. If the F/D isn't tuned correctly, you'll get too much loss in the system and the sensing circuits will tell you something's wrong. The digital stations will extinguish an LED. If I disconnect the pa, and the F/D, would this not eliminate the problem

Re: [Repeater-Builder] rebuilding R100 carcass - what is typically wrong?
I have one of these on the air in amateur service. Generally speaking they are dependable units. The most common problem seems to be the PA. The collector tab of the final transistor will unsolder itself from the circuit board. Usually all that is required is to clean everything up, re-solder the connection using silver solder and replace the two chip caps. The unit I currently have in service was retired from commercial service after a lightning strike about 15 years ago. We repaired it, installed it in a weather-proof box, and it spent the next 14 years installed 900 feet in the air on a tower. We have since moved it to another site. The Mototorla programming software can be problematic, but that is the only route to go if you are thinking of putting this collection of parts back together. The software is out there, and the programming interface is not difficult to build. You will need to go to the batlabs website and look up the info on hacking the software to allow you to progam the unit to the ham band. Contrary to popular belief, I successfully run the software on a 650MHz Celeron laptop without any issues.

Re: [Repeater-Builder] Requiring CTCSS
On one of the systems that I take care of, we fought interference from a paging transmitter for about 12 months before making the choice to go to PL access full time. In our case, the signal was weak enough that a mobile on the fringe of our coverage area could cover it, but strong enough to hit the receiver and bring the repeater up. We tried different receivers, additional cavities, etc. until the only alternative was to take the system down or go PL. In some (perhaps most) situations, despite expending a great deal of time, energy, and expense, the only workable solution to solve an interference issue is to go to tone access. Incidentally,a properly implemented PL tone decoder will detect subaudible tone before the squelch circuit in your receiver will unsquelch. This should have the effect of slightly increasing your talk-in range compared to a non-pl repeater. 73, Kevin, K9HX At 08:10 AM 12/3/2004 -0500, you wrote: I think that CTCSS is used too often on input as a crutch for solving (covering up) interference problems. I'll bet a properly-operating carrier-squelch repeater will work better than one with a tone, simply because it is open to interference that must be FIXED, not just covered up with tone. I learned this the hard way. I have a 6 meter machine at 51.7 right next to a TV channel 2 and a 70 MHz pager link transmitter, and many other high-power devices. It was toned input at first, (to shut it up) and operated very poorly until I spent time and money on filtering and a good receiver. I am proud to say now that it is open carrier squelch with no problems. I do have a tone on the output, where the user can implement it or not for receiving trouble.

[Repeater-Builder] MSF-5000 analog station programming
We have had a MSF-5000 station donated to replace of of our UHF repeaters. This sation is one of the older analog units that require a PROM to be programmed to change the frequency.

I have the opprutunity to help a group with a UHF MSF-5000 project.

Re: [Repeater-Builder] MSR2000 PA out - again...
There were two different PA decks on the MSR2000. One that was rated for continous duty and one that was not. The non-continous duty UHF PA is a real problem. It is not at all unusual to have cronic problems with it. The DC distribution is done on a circuit board that runs under the PA modules. The DC is broght up to the modules by way of jumpers made from square wire. The connection between the DC distribution board and these squre wires is very problematic. The only way to fix it is to completely disassemble to PA deck, desolder every connection, clean everything, and then resolder all of the connections using silver solder. This is a very involved job, and will result in a PA deck that will work for a few years before it is necessary to repeat the repair again. Another problem area is the interconnection straps between the various stages in the PA. Each strap should have a small hump in it. In other words, it should not be a flat strap between the substrates. The hump will allow for small amounts of movement between the substrates as the PA deck heats and cools. If you have the flat straps, the solder connections will eventually fail and the connections will be intermittent. The receiver in your machine is basically a Mitrek. One thing to look for that can cause intermittent problems are the ground connections on the coils in the front end casting. The joints can fracture and cause very intermittent RX sensitivity problems. Don't over look the two injection filter resonators that are part of this assembly. Get a friend and a couple LARGE soldering guns and resolder all of these connections. It will take a large amount of heat, but make sure that the solder flows properly and that the entire joint is fluid before you remove the heat. Following this repair, be prepared to touch up the aligmnment on the front end. I hope this is useful information for you. Good luck, and 73, Kevin, K9HX At 09:00 AM 9/7/2004 -0500, you wrote: I have an MSR2000 on 444.550 for the local ham club / county EMA. The PA (a 110W model) is out again. We just had this repaired by the local Motorola shop, with whom we've had very good results from in the past. We're running the PA at about 80W, so I'm thinking we didn't burn it up, but I can't help but wonder if there is anything inherently wrong with the MSR2000 PA for UHF. This is the third time the PA has failed in this particular machine in about a 2-year time frame. (This was a repeater originally tuned for 460 MHZ, and brought down to the ham band.) This particular machine has been a pain in the @$% - RX sensitivity isn't what it should be, PA keeps going out, etc. Seems like we're up at the site every couple of months do make some sort of repair on it. I'm wondering if we should just cut our losses and get another machine, or should I keep plugging away at this repeater? If we do decide to chuck it, how much can I expect to spend to get a comparable replacement - we use this machine during severe weather season for forwarding reports to the NWS, and it's open other times. We want to add remote RX sites (you've probably seen my inquiries about those in the past) but I don't want to start adding remote RX sites until I get the main repeater working reliably.

[Repeater-Builder] 2 UHF receivers, one antenna
Over the weekend, I added a second UHF control receiver at one of the sites I take care of. The control RX antenna is up about 150ft. Previous to adding the new RX, I could easily access the first RX about 25 miles out. Since adding the second RX, I can only access either one about 12-15 miles out. I simply put a tee connector on the polyphaser and connected both lines to it. Not the best engineering practice, but I have gotten away with it before. Does anyone have an idea about how to properly match two receivers to one antenna? The receivers are located in different racks in different parts of the building. I know Motorola and GE had passive devices to do this job. Is there a way to build something homebrew to do this job? TIA, and 73, Kevin, K9HX Yahoo!

Re: [Repeater-Builder] SS-32/5K/Micor
Thanks for your thoughts Bob. I have managed to minimize the problem by doing as you suggested - I put a .1 uF cap and a 27K resistor is series with the tone output of the SS-32. The frequency still drifts when the tone is keyed and unkeyed, but now only about 50-60 Hz. I think that this is acceptable. 73, Kevin, K9HX At 10:16 PM 8/29/2004 -0400, you wrote: Hi Kevin, I am installing a Comm Spec SS-32 encoder in a Micor repeater. I am using a logic output from an S-Com 5K controller to key the ground connection to the encoder whenever the RX COR is active. I need to do this to be able to link into another system. My problem is when ever the encoder is keyed or unkeyed, it causes the TX to drift off frequency about +/- 900Hz. It apears that this is being casued by a cap charging/discharging. I have tried several different tone insertion points, always with the same result. I haven't seen many responses, so I'll toss out some suggestions. There is probably a DC bias on the Micor side of the audio connection. The SS-32 has a 1 uF polarized cap in series with the tone output with its + side toward the SS-32. When the SS-32 has its ground connection floating, the cap probably sees 12V on the SS-32 side and some other (lower) voltage on the Micor side. When the SS-32 is operating, the voltage on the SS-32 side of the cap may be lower than the Micor side. If the cap operates reversed biased, it can leak or short, causing wierd problems. You could try a 1 uF nonpolarized cap in series with the tone lead to see if that's the case. If that wasn't the problem, and if you have plenty of CTCSS level coming from the SS-32 and can afford to lose some, use a smaller nonpolarized cap (say, 0.1 uF) in series. The lower value will attenuate the level, but may also reduce the drift effect you're seeing. 73, Bob, WA9FBO Yahoo!
