[Repeater-Builder] Re: PC-to-Radio-to-Repeater site: DTMF Dialer program
If you are running Echolink in sysop mode you can use the local Keyline to do the keying. Another way is to do a VBScript..this is a visual Basic Script that will allow you to change the state of a handshake line on the 232 port. I use a freeware program called DTMF DIAL it's small but it works well.

[Repeater-Builder] Re: need slug for GE Delta
Hi Gang First, Thanks Jeff for the slugs!! Just a note about this post re GC 9440 for tuning the DELTA 0.05 coils. I ordered three of these diddle sticks from Newark Electronics, it was 10 cents more for the tool but cost 8 bucks less to ship. After doing a little research I found that the square end is 1/16 which is 0.0625 not 0.050 when you use this end to turn the slug you are really using the little blade that protrudes from the square end. With a little carefull doctoring with a jewlers file you can get it so that it fits nicely. I have found in the past that any thing that doesn't fit the hole nearly perfectly will crack the slug so be careful and if they fit tight try taking out the slug and run the proper sized screw into the full length of the form to re-round it.

[Repeater-Builder] Re: GE MASTRII UHF PA PL19d424895g32 repair
You can disconnect the driver board and connect a jumper from it to a dummy load and check the power each stage is 50 ohms impedance. I have seen the power regulator transistor open up before, but it kills the power to the collector of the transistors in the driver. Pray that this is the problem it's the same one used for the audio PA. If you have up to about 40 watts then It is the main deck. It's usually cheaper to just replace it if it's bad. What you remember reading is likely the problem with the bonding strap that feeds power from the PA to the Output filter opening up or comming unsoldered.

A common mode choke, if it has sufficient reactance at the noise frequency, can eliminate the noise. A common mode choke is an inductor with a single core (toroidal is good) and two identical windings connected such that each winding is in series with one of the long lines. The choke goes at the input end with the phasing dots on the same side, i.e., either toward the line or toward the equipment input. The desired signal current flows in opposite directions on the two lines and creates opposing magnetic fields in the choke, which cancel. The desired signal never sees the choke and its waveform is maintained. The undesired signal (common mode) current flows in the same direction in both lines and sees a lot of reactance in the choke because the two magnetic fields add. Much of the noise is eliminated. 73, Bob Bob Schmid, WA9FBO, Member S-COM, LLC www.scomcontrollers.com Hi Jim, The cable I used was armored with a spiral copper shield over 5 twisted pair lines.

I used 600:600 isolation transformers in the audio input and output lines at the repeater. It all became a mute point when the cable got mowed in two during a grass cutting this last summer, and then we lost the public IP address and EchoLink was no longer usable.

I think you may be on the right track with a ¼ wave open stub between the duplexer and the receiver. try and use a good low loss piece of coax for the stub...like ¼ or half inch superflex the lower loss the higher Q the notch will be. start a bit long and shorten it a bit at a time to tune. The reason that I Know this kind of thing will work for some types of problems is that I had the exact reverse happen to me. I had a 900 Mhz Paging transmitter getting into my 2 meter repeater a few years ago. I cured it with a BNC TEE and a very short piece of RG58 I got close to 27 or so db of notch at the Paging transmitter frequency and it cured the problem...This thing was getting into the front end of a GE MASTRII Receiver...It was one of thoes crappy third party 900 transmitters built FOR MOTOROLA by someone else.

As others have mentioned the maxtrac has a lot of plastic. A shielded box with no unbypassed wires going in and out may help. Ferrites on the feedline or a coil in the feedline may help as well as some more grounds on the feedline. There are also isolation transformers that could be used at 900 mhz. but they are rare. Mini Circuits may have them. I once had to mount a UHF Micor receiver in a shielded box as it picked up cell phones otherwise. I have operated amateur repeaters in broadcast facilities since the 1970's. It's not unusual to measure +30 or even +40 dbm coming down a feedline from an antenna mounted not far from an FM broadcasting antenna. I have been bitten with RF burns from such feedlines more than one. I have enjoyed much success getting rid of these problems with just a 1/4 wave shorted stub at the repeater frequencies. However, this apparently is not your situation. With all the things you've tried to no avail, any 104.9 mhz. energy on the inside of the feedline doesn't sound like the culprit. That's why I think it is RF on the shield. I have been in a great many broadcasting facilities. Many are very well done with much attention to details. You could eat off the floor and feel good about it. But many are a real pit with little attention to detail - just get it on the air. The grounding in these installations is next to non-existant. Having not seen your neigbor's setup on 104.9, I can't evaluate it. I also don't know the amount of grounding and bypassing on your 900 mhz. setup. But, based on my experience, I would suspect a feedline hot with RFon its outside. It might be interesting to visit your neighbor and see how he is receiving his 940 mhz. studio-transmitter link, which is apparently unaffected by his 104.9 mhz. transmitter.

D-Star repeaters and the analog repeater systems you are accustomed to are all FM and all conventional. D-Star is a digital audio format, that's all. It still operates on an FM carrier. What I think you mean to say is that the D-Star repeaters do not pass an analog audio FM signal as well as a D-Star digital audio FM signal. I also wish they did this. In the U.S. land/mobile industry that uses the P25 digital audio format this is known as mixed mode (a term Motorola coined). I agree that Icom missed the boat when they did not build this feature into the new D-Star repeater systems. Perhaps they were unable to overcome some technical barrier, I don't know and they won't say (neither Icom or Icom America). Also, as you pointed out, D-Star digital voice is a narrowband signal occupying only about 6Khz vs. the 25Khz or so that amateur repeaters have often required to date. It is difficult to do a comparison between a digital audio system like D-Star and a conventional analog system so what my friends and I have done instead is we programmed several channels in our D-Star radios with the same simplex frequency only one channel is set for DV (D-Star digital voice) and another is set for narrowband analog while a third is set for wideband analog. We have performed numerous point-to-point (simplex) comparisons under varying conditions (day, night, clear, rain, dry, humid, etc.) so that we could each hear the differences for ourselves. Under some conditions analog works just fine and certainly sounds more natural but under other conditions, especially long distance, the digital voice can make communication more readily possible by audio compression and virtually eliminating the path noise that we usually hear on a distant analog signal. I frequently use P25 conventional, D-Star, and analog equipment and while the D-Star format and its error correction abilities may not be the best it does a very good job and I hope more amateurs explore this digital voice format and, I hope more amateur equipment manufacturers offer D-Star capable gear. Soon I hope to try out the European TETRA digital format for more comparison and education. These are the voice modes of tomorrow so I think it's in my best interests to learn them today. 73, Gary Coy Hilton wrote: This brings some questions to mind. none of the D-STAR repeaters that I know of (ICOM) have the ability to do FM repeat, If the repeaters, antennas and the rest of the equipment weren't the same or nearly the same and coo-located how can the test be fair?

[Repeater-Builder] Re: Master II UHF repeater station stays keyed...
Have you swapped the 10 volt regulator board with a known good one? It has happened that something can short a line on the back plain...this could be a key line to the 10 volt board. My point to having you check the locations were to find out if something off the board was pulling one of the key inputs low or if the board has a shorted keying transistor. If one of the lines are low, then follow it completely to where ever it goes, and check it for a short to ground. Something is pulled to ground to get the RED LED to turn on, or Q5 or Q6...more likely, Q6 may be shorted. If none of the inputs are pulled low then the problem is on the regulator board. Otherwise it is an input to the board. Now, there's nothing difficult about this, it's simple DC troubleshooting. You should be able to track it down in a little while when all other possabilities have been exausted then what ever is left must be the truth. Fred shouldn't have to come to help with this you should be able to track it down...You'll remember it better next time, and you will learn some trouble shooting tricks from it.

Coordination needs some oversite, some seperate organization that watches what the coordination entities are doing. Since coordination is volentary, it is not a requirement, the FCC will not do anything. Coordinatation entities know this and can bend things around, make things up, then say, you didn't do this or that and you lost your coordination all relying on 'ther word' no proof, no one watching them. Its starting to seem like coordination entities are taking it way too extreme, playing favortism, playing games with repeater owners trying to free up frequencies for their friends... etc etc. By the way, 444.275 is on the air, and will remain that way. Let them coordinate another repeater on that frequency pair, I'll just turn up the wattage and wait for the citations... then haul WAR into the court/fcc procedings to answer for their game playing... and make them use up the money they have stashed aside by making them use it up on attorney fees.

Dwayne, you are right... The cable length Mst be 1/4 electrical wave length to come out right just like the ones on your exesisting duplexer. This is shorter than the calculated wavelength in free space because the RF propegates slower in coax than free space. You have to determine the velocity factor of the cabel that you are using between the duplexer and the cavity and then use it to determine the correct length. Cut the cable as exactly as possible to that length THEN put the connectors on it.

This is probably where the right angle connector trick would come into play. Thanks for you input, that really helped track it down. Dwayne Kincaid WD8OYG I think the length of coax you use between that BP filter and the rest of the duplexer is critical. I have a 900 MHz duplexer that has a BP filter and a BP/BR filter on each side. The BP filter gives me 25dB attenuation 25 MHz away, and the BP/BR gives me about 45dB. But when connected together with what seems to be a 1/2 wavelength coax, I get 90dB attenuation. The whole is greater than the sum of its parts, somehow. I'd suggest trying a piece of coax that's the same length as what's being used now, which might be 1/4 or 1/2 wavelength, to couple your BP filter to the duplexer.

It provides about 77 db of isolation with 1.4 db of loss. This is just about what the spec says, so that all looks good. I happen to have some extra PD-1173 VHF band pass cans, so I'm thinking of adding a can on each side to get the rejection up to 85 db or so for use on a VHF repeater (Exec II base station at 25 watts). The bandpass can by its self shows about 0.5 db loss and 8 db of rejection at 600 KHz. The curve on the spectrum analyzer looks good and the return loss is very good (-40). Here is where it gets messed up. I added a can on the duplexer on the radio side (let's just say the RX side). The loss goes up to 1.9 db as expected and the return loss is still good. But when I go to measure the rejection, it now shows only 73 db. How can this be? Everything uses double sheilded cable and attenuator pads are used on the input and output to the analyzer. It seems like the rejection should be additive, but for some reason it's not showing up that way. Anyone know why? Dwayne Kincaid WD8OYG __ Do You Yahoo!? Tired of spam? Yahoo!

Perhaps there is something in NFPA that requires the area in which the elevator equipment is located be properly protected from access by anyone else?

OKAY you Delta guys, I picked up a couple really neat GE DELTA S radios at this past weekend for 5 bucks each. They are VHF 150.8 to 174 and 110 watt units. They are neat little guys but have no proms but that doesn't seam to be the problem. I need a binary copy of a prom that is known to work at around 154 MHz. I'm very familiar with this type of memory. I have downloaded some info from Dave Karr, KA9FUR about the format of the data storage, but I need a known good file to test the radios with and compare my data with after generating a file from the data that I downloaded. I will be using a EETOOLS prom burner to read the binary files and burn the test prom with. I have found a source for the proms at a decent price if any needs some.

[Repeater-Builder] Re: controller question
First, If you have an IRLP node and an Echolink node and tie them togeather, so that Echolink can talk into the IRLP node then youre likely to get cut off the IRLP end they strictly say that you will not do that!, Now having said that there is a program called ECHOIRLP That will eather/or to beused from the same machine(computer repeater). IT runs on LINUX RED HAT FEDORA...I cant remember what version , but I think it was the last release. I run Echolink on my machine at Walt Disney World and have for about three years and I like it very much. Most of the people that I meet are great folks! As far as the controller well it depends on your setup. I have brouad band at home and shoot the Echolink to the repeater via RF link IT is simple. I use a simple NHRC2 Controller. They are not expensive ( a partial kit is around 40 bucks and is easy to build in an evening) and they work well and last a long time.

When I worked in the two way shop before I was licensed as a HAM I remember listening to a local repeater and thinking how great it sounded compaired to the equipment that we had and with much less money spent, and older equipment.

Perhaps the best analogy would be a Hewlett-Packard power meter, where the sensor is matched to, and calibrated with, the meter itself. If the sensor should somehow be destroyed by accident, one could not simply purchase a new sensor and expect it to work with the existing meter. One must ship the meter and the sensor back to the factory for alignment and calibration. Like the crystal and the channel element, they are a matched pair. While I understand and respect the opinions of those who maintain that Amateur Radio transmitters can embrace a much more relaxed level of precision than commercial transmitters, I cannot help but wonder why this feeling is so pervasive. My personal feeling is that the public impression of Amateur Radio (notice the capitals!) is greatly enhanced when such installations meet or exceed the workmanship levels found in a typical commercial installation. Many others more vocal than I have lamented that some installations by Amateur Radio licensees have been so amateurish that they demean the name. I submit that an Amateur Radio repeater should always incorporate the State of the Art, with the appropriate bandpass cavities, isolators, filters, and components that will ensure a reliable, trouble-free installation. Moreover, I cringe when I hear that a substandard installation is okay, simply because it's only an Amateur Radio project!

From reading your post, what I'm getting is that the Icom is keying the VXR5000 okay. When the VXR5000 receives the responding radio that it isn'y keying the ICOM. If that is right, you also need a similar circuit from the COS circuit in the VXR5000 to key the ICOM. .NEVER CONNECT ONE TYPE OF RADIO TO ANOTHER WITH OUT SOME KIND OF BUFFERING CIRCUIT like the transistor switch that you have built, with out completely understand both circuits. after you let the smoke out it is too late to say AAA CRAP GOOD LUCK! --- In Repeater-Builder@yahoogroups.com, n2len [EMAIL PROTECTED] wrote: Hello, I am presently hooking ua remote base radio to my vxr5000.

Jeff, how's the driver PA harness built and how are the 2 PAs outputs combined? Do you have any information or specs on the RF and matching harnesses and how they are built? --- In Repeater-Builder@yahoogroups.com, Jeff DePolo WN3A [EMAIL PROTECTED] wrote: I am looking at acquiring a GE Master II UHF Base station. This is a 300 watt solid state transmitter, which how I understand it, has 2 PAs running in parallel. It's actually 200 watts, and yes, there are two final PA's, each capable of 100 watts output, that are combined. However, each final PA requires around 35 watts of drive - the final PA's are really the same as a 100 watt station PA, but without the 40 watt driver board. Drive to the PA's is provided by a standard 100 watt PA. So, what you have is the exciter (200 mW) driving the intermediate PA (100 watt, attached to the main station chassis), which gets power-divided to feed the two final PA's, the output of which then are combined to yield 200 watts. What I am wondering is, can these amps be run separately, or do they always have to run together in parallel? Not really, since each requires about 35 watts drive, so you still need something to drive them with. If you only want 100 watts, then just run the 100 watt IPA to the antenna and leave the two final PA's on the shelf as spare parts. --- Jeff Yahoo!

Well Randy, now that you have had your tongue lashing. Try placing a 2 or 5 Pf cap across the crystal and see if it brings the thing into range. If it brings it down but not enough try a 10Pf or so. This may get you into range but you will have to test the modified module through the entire temp range and adjust your caps temp coeficent to keep the thing on freq. Let us know how it goes.

Does anyone have any technical docs on the Micor channel elements and the require capacitor changes? The channel element is KXN1052A. I would rather replace the required cap with the correct value and get this repeater on the air instead of waiting another 3 weeks for ICM.

Right Ken, You're question of WHY would anyone use a chip when a transistor an one or two resistors would do is a good one. the only answer that I can think of is that the person using it doesn't know how to do it with transistors. Actually with a EXEC II and MVP (and likely the MASTR II) you don't even need the transistor in the base because they have a 10K to +10v that is floating when the radio is unsquelched and pulled to ground with a NPN when it is squelched. 73 AC0Y --- In Repeater-Builder@yahoogroups.com, Ken Arck [EMAIL PROTECTED] wrote: The IC you speak of is a standard, run-of-the-mill CD4049 CMOS hex inverter and the 4050 is a standard CMOS hex NON-inverting buffer.

[Repeater-Builder] Re: Multiple receivers one antenna ???
It may sound interesting (and cheap) but the reason that no one else has suggested it is because the impedance miss matches it causes. That is why you need something like a multicoupler whis is first a pre amp to keep the loss to a minimum then sends the pre amp to a splitter that maintains the 50 ohm match required by the receivers on each output port. If this approach was workable then the cable company would NEVER buy a splitter but would buy TEEs --- In Repeater-Builder@yahoogroups.com, Vincent Caruso [EMAIL PROTECTED] wrote: That sounds like an interesting solution, I would be interested in learning more about it.

[Repeater-Builder] Re: UHF Preamplifier
Unless your test banch is inside a Fariday Cage you can'y rule out extraneous signals. If there is a strong transmitter near by it's still questionable. But you're right about off frequency or off channel signals causing quieting in the receiver. This is another reason for pre filtering the input to a preamp. preamps are generally broad banded devices. It's better to control what you are amplifying by 17db (read, just what's on your input frequency) than to amplify everything in the band by 17db. This sort of thing can amplify a strong co-channel signal to the point of desensing or overloading the receiver (hint, on 2 meters (VHF)your transmitter is 600Kc away) even in a quiet area. 73 MERRY CHRISTMAS AC0Y --- In Repeater-Builder@yahoogroups.com, Kevin Custer [EMAIL PROTECTED] wrote: Think about this for a minute, if the noise level increased, the squelch circuit would have seen MORE noise and rammed the squelch closed. What actually happened is, adding a better device in front of the receiver lowered the receivers total noise figure, decreasing the noise in the squelch circuit, requiring the squelch pot to be set tighter. Very common effect. Common? Must be another explanation, as you're talking apples oranges here w.r.t. noise. Remember this is FM, so more noise power at the front end doesn't mean more noise at the discriminator unless the limiter isn't being driven into limiting, which is probably what's happening. But adding a preamp can only add total noise power, never subtract. Bob NO6B If what you are saying is correct, adding the preamplifier should have placed a receiver lacking in overall gain into full (or at least more) limiting. If so, this would have raised the noise level to the discriminator, thus tightening the squelch. He commented that he needed to set the squelch pot tighter, which means there was less noise present after the installation of the preamp. Maybe I didn't explain it well, but I have seen this effect before, even on the bench where extraneous signals quieting the receiver can be ruled out. Kevin Yahoo!

Al, Having to cover that band you should Notch out the paging transmitters. All preamps that I know of are broad band devices and that is likely why you got over loading.

[Repeater-Builder] Re: GE MASTER II BASE STATION CWID-51B
question. you can make a COR low by inverting the CAS or RUS signal which goes high when the receiver is quited or receiving (normally one and the same). You can use a 20k resistor or so and a 2N3904 or a 2N ( any general purpose NPN transistor. I would sugest building it on a small board such as can be had at Radio Shack. Connect the emitter to A-. Connect one side of the resistor to the base of the transistor and the other end of the resistor to the CAS/RUS. The collector goes to the COR low input of the CWID-51B. difference between the CAS and RUS is the CAS goes active (high) anytime the receiver receives anything. the RUS goes active (high) only when the receiver is receiving AND the CG is detecting the proper tone. If you are not using a GE Channel Guard tone decoder then the RUS will track the CAS. I hope this helps.

Even a 12 bit sampel at 40 KS/s would likely give most people fits to detect except for the Great quality.

[Repeater-Builder] Re: Update: Looking for a UHF Circulator and load
Well Bob I'd bet the problem is gone for good. There's nothing like having really good feed back from your antenna to the area of your receiver with out going through the receive side of the duplexer. It sounds like a little item called a passive repeater, think about it. I'm interested in the 4 can duplexer, I would like to know the make. Not bad for a 200 watt transmitter. AC0Y --- In Repeater-Builder@yahoogroups.com, Bob M. [EMAIL PROTECTED] wrote: First, I would like to thank everyone who responded to my original post with suggestions, information, and similar problems. Here's an update to the situation. Late Monday afternoon/evening, the coax/antenna was swept (from the bottom) with a site-master unit and no problem was found. There's an unused 800 MHz vertical antenna mounted near the UHF antenna, on the platform, with coax attached. Apparently the dummy load at the bottom of the coax for that antenna was either missing or defective, so another one was put on. The repeater's desense problem is completely gone now, even with the 200w PA and the 17dB gain preamp. I don't know if there was desense immediately before playing with that dummy load, nor if they restored the situation to what it was previously to check if the desense reappeared. For all we know, with the high winds and rain we had Monday, something up at the antenna (the jumper, for example) could have moved enough to _cure_ the problem, even temporarily. Nothing else was done at the site on Monday, but the repeater is working as good as it was when it first went on the air. If the desense condition returns, we'll obviously have to go looking for it again, but maybe a visit to the top of the pole would be in order. Anyway, my search for a circulator is temporarily on hold. Sure, it would be desirable to have one, but not absolutely necessary for proper operation of the repeater. Bob M. __ Yahoo!

[Repeater-Builder] Re: Controller
Paul, If you don't need the second radio port, look at the NHRC 2 it's a great controller you can build it with or without the voice ID'er. Contact Jeff or Pete at NHRC they may make you a deal on 10. they're nice guys and have great product.

Looking for anyone with real-world experience with Flash Technology FH-324 red/white flash tower obstruction lighting. In the 18 month period following new installation all three red 'beacons' have failed. Tower mounted flash heads have a coupling transformer, trigger transformer, RC network and flash tube. In red beacon failures how often has trouble been in components *other* than the flash tube? Is it true red flash tube shelf-life is six months or less? What has the real-world life expectancy (in operation) of the red flash tubes been? FYI, trouble was isolated to the flash heads by swapping cables at the Power Controllers. Trouble stayed with the flash head. Flash heads failed in succession over a period of 4-5 months. Moderator: If this is too far OT don't hesitate to kill. TIA... Doug Zastrow _ YAHOO!

[Repeater-Builder] Re: decibel duplexer
If they are free then takr them you may be able to use them later. I have used cans like these for several projects requiring additional isolation. Besides, if you can get enough of them, you might be able to build a good duplexer. So if anyone has cans or old duplexers that they want to get rid of..just send them my way. There is always places for cans in class or else where. --- In Repeater-Builder@yahoogroups.com, BOB UNICK [EMAIL PROTECTED] wrote: Thanks that what I thought --- Mathew Quaife [EMAIL PROTECTED] wrote: Hi Bob, at 3 meg split, these will not work work, since you are at a 600KC split, less than 1 meg.

[Repeater-Builder] Re: Batteries in Parallel
No Jack, that is not an exaggeration Ive seen lead acid batteries blow off front quarter panels on cars and blow cabinet doors off from slight misuse. Hydrogen gas is nothing to play with. And as for fire hazzards, high currents can cause a fire pretty quick. Just put a piece of #22 bare wire across your car battery and watch it glow for a second before it burns open. --- In Repeater-Builder@yahoogroups.com, Jack Bitzer [EMAIL PROTECTED] wrote: Seems like an exageration to me. Most likely outcome would be that the system would continue to overheat until both batteries went below 11 volts. Possibly the charger would blow a fuse or burn out. IF you call that a fire..ok. I have seen a battery explode when there was not much electrolyte left and a large amount of current was applied to it. I guess a spark between the plates ignited hydrogen generated from the gassing of the remaining electrolyte and as the caps were still on it blew a corner out of the case.

To add to the many other comments I recently drove a ham to a remotish link radio site and helped him a bit with replacing the batteries. They were two auto batteries from totally different manufacturers. One was so hot you could barely touch it. The other was room temperature. The battery charger had gotten very hot as well. So much so it was uncomfortably warm to the touch five minutes later. The ham, who has vastly more experience than I do, stated there could've been a fire within days. The two batteries were replaced with a highway truck sized battery which was the same size as the two previous batteries put together. Tony Yahoo! Groups Links __ Do You Yahoo!? Tired of spam? Yahoo!
