Re: [Repeater-Builder] Wacom WP-639 Duplexer question
Rich, The short answer is: You need to find a bigger duplexer. Four 8 cans would work well such as a Wacom WP-641. You could simply call and order one if Wacom was still in business. (RIP) Unfortunately Tx/Rx bought them years ago for the name and to quash competition. They can be found occasionally for around $600 or so on the used market. Other alternatives are as follows: 1) You can use two antennas and split the 639 duplexer so that 2 cans are in series between the TX and the TX antenna, and the other two are in series between the RX and the RX antenna. Terry WX3M a list member is doing this with VERY good results on one of his VHF machines. Of course this involves the expense of additional feedline and a second antenna. I think you said you had this machine on an 80' mast. 50' or so of vertical isolation coupled with the additional isolation of splitting the duplexer *may* be enough isolation to get rid of all the desense. TX goes on bottom, RX on top. 2) Buy additional Band Pass / Band Reject (BPBR) cans. You can add these additional cans between the Tx and/or Rx and the duplexer. These cans will give additional isolation. Even if you can find just Pass or Notch cavities, tune them and put them in the correct place. With both of the above options, you are looking to add to the isolation between your transmitter and receiver. You'll find you'll do best by adding cans to your transmitter that notch side-band noise at your receiver's frequency. In other words, do what you can to insure your receiver is not hearing your own transmitter's sideband noise on it's input. Pass cans tuned to the TX frequency or NOTCH cavities tuned to your *RX* frequency placed in the transmit line are your best hope.

[Repeater-Builder] GE MII high power metering

Re: [Repeater-Builder] Crossband Repeater - Desense? High Pass Filter Needed?
A few questions to which the answers would be extremely helpful: * What are the frequencies in question? * Are they harmonically related? * How much vertical separation is there between the two antennas on the tower? * Are they directly one above the other? * What is the gain of the two antennas? * Which band is on the top? * Did the system *ever* work without desense, or has something changed? If something has changed: * Are the antennas and feedlines visibly OK? * What sort of feedline is being used? 9913? * Any new neighbors on the hill? * Any recent lightning? A low-pass filter on the LB Tx may help. It could be the harmonics of the LB Tx clobbering the VHF Rx. Have you looked at the output of the LB Tx on a spectrum analyzer in the VHF area? Some (Motorola Micor) LB Tx's have a low-pass filter *after* the PA and before the antenna output. Does your Midland have something similar? This would definitely help suppress the harmonics. If your Midland doesn't seem to have a LPF after the PA and the spectrum analyzer shows lots of noise in the VHF area, I would get a hold of a Micor LB LPF and put it in series and see if that helps. They are designed to be 50 ohms in /out and are rated for 100W or so. Scott Scott Zimmerman Amateur Radio Call N3XCC 474 Barnett Road Boswell, PA 15531 tritium242 wrote: Hello all. We have a cross band repeater (Midland 100W VHF low w/ 1W VHF high band repeater built in). What we noticed is that in the High Band -- Low Band direction, the high band side will receive the signal, then the low band Tx will key up to repeat the signal. Normally, all works just fine. But at extended distances, the low band TX keying up will deafen the high band side trying to copy the faint signal (from an HT), resulting in a choppy, unintelligible signal at the max distance. This is only with a faint/distant enough signal, like a HT at a distance. In the other direction (low band -- high band), there is a HUGE increase in maximum distance, even with just 1W from the high band Tx going out, since it seems to be not enough power to desense the low band Rx. Long story short, will adding a high pass filter to the high band side to shield the high band Rx from the powerful low band Tx do the trick? Where can one find such a thing? It just has to pass from say, 100-120 Mhz, and block everything below it, and tolerate 1W of Tx power is all. We'd like to avoid using a big, bulky cavity filter if possible, since we don't need monster isolation figures, or high power handling capabilities. Thanks in advance for any ideas! Yahoo!

Re: [Repeater-Builder] Lost 10 volts in a Master II UHF Repeater
I would look for a shorted tantalum capacitor hanging somewhere on the 10V rail. If you hook 10V from an outside source to the 10V buss, you'll probably find it's drawing all kinds of current. The 10V regulator circuit will go into fold back before burning up. This is by design. I usually hook a source of 10V at about 1.5A and look for smoke. It's usually one of the tantalum capacitors that starts to smoke. Once it's done smoking, problem solved!! I have lost track of how many shorted tantalums I have had over the years. When they occur in the B+ of the high current PA supply, they simply burn up and th problem fixes itself. The 10V regulator doesn't have enough guts to burn them up, so they stay shorted and wait for someone to find them. Often times it is a cap on the mixer board. Those are fed though a resistor of a few ohms.

Re: [Repeater-Builder] Re: MSF5k - No Tx
That would have helped greatly!!! I found the issue earlier though. I used Bob's article on the RB site about using the MSF-5k without the PA: http://www.repeater-builder.com/motorola/msf/msf5000-without-pa.html This gave me power out of the LLA. (About 16W) It was pretty easy to figure it out from there - if there's power going to the PA and nothing coming out... Problem is in the PA!! Opened the PA and found a burned trace. Flowed it with solder, plugged the station in and the same trace vaporized again. It turns out the coupling capacitor between the final driver stage and the load balancer shorted out!! Replaced it with one scavenged from a Micor and all works well. Thanks for all those that helped me in my quest. I'll print this new procedure and put it in my manual for future reference.

Re: [Repeater-Builder] D-Star Was: Molotora Gontor
My biggest problem with the D-Star repeaters is that they didn't make them analog compatible. Knowing as little as I do about the D-star hardware, it would seem easy enough for Icom to have done so. All they would have needed to do would have been to look at the incoming signal, see if it was analog or digital, and process it correctly. While you'll pry my analog repeater pairs from my cold dead hands; if D-Star machines were analog capable, I'd swap every pair I have to that format tomorrow. As RB (the company) I have been asked about D-star more times than I can count. I tell people it's nice to play with, but what happens in an emergency? If Icom would have made the D-star machines analog capable, those that wanted to (and had D-star radios) could play with it all they wanted to. When an emergency arose and you had 10x as many people out there with analog rigs, the machine would *still* be useful. As it is at present, if an emergency arises, only those with D-star rigs can use a D-star machine. That concept is fine, as long as ALL of your volunteers have D-Star radios! (How many places is this the case?) Around here (Western PA) the governments bought Icom D-Star radios for RACES. I had no objection to that since those radios can be used in analog modes with analog repeaters. Now they are wanting to get D-Star repeaters for RACES and emergency use. I *strongly* object to that since they CANNOT be used in analog modes for emergencies. In my view, you'd be alienating much of your volunteer base that doesn't have the correct equipment right at the point where you need all the help you can get! Of course with the government in the mentality that they have been in the past few years, maybe that's their way of thinning the heard. I *think* I remember someone saying that some other company had made an analog capable D-Star controller? Do any of you list members know anything about that?

Re: [Repeater-Builder] RE: follow up on lightening strike last spring
Since your chief complaint is noise, you need to define the noise. Noise in repeaters can be from MANY other sources besides duplexers. Sure your cans *might* be at fault, but if you're not having desense issues, I would not suspect them right off. Is there anything loose on the tower? What kind of antenna are you using? Is it broke inside? Is anyone else at the site having noise issues, or just you? Is there anything loose on the tower as a result of the lightning? (burnt off grounds, etc.) Is there a PolyPhaser or similar device in the line that might be causing trouble? Will the repeater duplex into a dummy load with no noise? If so, your problem is not in the repeater, interconnect cables, or duplexer. It's in your feedline or antenna. Lightning can do funny things to antennas and feedline that are not readily visible to the eye without disassembly. Busted antennas can cause noise VERY easily. (for obvious reasons) If it *will* duplex into a dummy load without noise, take a dummy load to the top of the tower and see if it duplexes OK in that configuration. If it works with the load in place, your looking at a busted antenna or loose, broken, cracked tower hardware or grounds. Good luck, Scott Scott Zimmerman Amateur Radio Call N3XCC 474 Barnett Road Boswell, PA 15531 Richard wrote: I know its been a long time since I first posed the question on what might be causing the noise we were experiencing after being hit by lightening. After many trips to the Technical shop for testing, we replaced the repeater ( was a vertex 5000, now a Icom ur2000) and are in process of checking out controllers. The duplexers were my big worry. And yes, it would seem that concern wasn't unfounded. We started experiencing a degradation on the receive side of the repeater and then, a leakage from the cans. We had the duplexers checked out with two different service monitors and found nothing! The technician who works on duplexers took ours apart and found only a little bit of carbon, but that was it. they checked out ok. We put them back into service and the noise was there making communications impossible. We are now going to replace them with a 6 configuration instead of the four we have been using. My question to the list is, besides the noise factor and crackling noise, is there any other methode of discovering if the can's are bad or not? Yes, I did and have been losing sleep over this one.

Re: [Repeater-Builder] Repeater Audio samples
While I don't have any recordings for you, I can assure you that ALL machines I build have audio responses that sound as close to simplex as possible. When I am finished with a machine, I have a helper in another room talk into the repeater's input while I toggle my receiver between the receiver's input and output frequencies. If they don't sound REALLY close, the machine doesn't leave my shop. There are many things that can lead to distortion in a repeater's audio path. Among these are discriminator response, PL filtering, (if used) controller bandwidth and distortion, and exciter frequency response. The most likely causes of audio response issues are the controller and exciter modulator. Since you describe the audio response as either 'tinny' or 'muffled' that tells me that the audio input response of the controller is not configured properly. *Most* controllers can be used with both discriminator audio or de-emphasized audio. This is often jumper selectable, but sometimes component changes are necessary. I will leave it to the reader to do further research on what these two type of audio are, but suffice to say that most controllers expect to see discriminator audio and have on-board de-emphasis circuitry to make the audio response flat again. If the repeater in question has a 'boomy' sound to it, this is likely a sign of too much low-end audio response. The audio is more than likely being de-emphasized twice inside the system. The best and easiest way to fix this is to remove the extra de-emphasis circuitry. This can sometimes be done on the input circuitry of the controller. If it can't be done there, you may have to look at your Rx audio source. It is common practice to those who don't know any better to use audio from the speaker. It's convenient and it squelches when the repeater is not active. This is a BAD idea. Not only is the audio WAYYY to loud from a speaker's output, it's bound to the volume control. If someone is at the repeater site and decides he wants to listen in on a conversation, there goes the audio setting for the repeater!! Speaker audio is a good example of de-emphasized audio. If the repeater audio sounds 'tinny' it has too many high frequency components. In this case, an additional stage of de-emphasis is required. Again, the easiest way to add this is in the controller's audio circuitry. If the audio is 'muffled', it is probably being processed (compressed) too hard. Inside a transmitter there is circuitry that keeps the audio tamed down and in check to avoid overmodulaton and other band things from happening. This circuitry can only do so much. If it is getting hit with an audio source that is WAYYY to loud, it simply slams it to the ground, hence making it sound bad. This is an over-simplification, but more information on audio processing and how to *properly* set it up can be found in the repeater-builder.com site.: http://www.repeater-builder.com/tech-info/audioprocessing.html (This may be a bit over your head)[sorry Jeff] http://www.repeater-builder.com/tech-info/fmtheorydiscussion.html Sounded like a simple enough question didn't it!!

Re: [Repeater-Builder] WTB Mastr II PLL Exciter
The PLL exciters with the missing daughter boards are more and more common. I have a whole stack of radios with PLL exciters, but missing the daughter boards. (the BPF and audio processor) We at Repeater-Builder have brewed up a BPF module that is a direct replacement for the OEM GE version. I have parts to stuff them for either 136-150, 150-174 or 220-225 MHz. These boards are $20 each. We have also in the process of laying out an OEM style audio processor for the PLL exciter. These will be completed as time permits. These will sell for around $30 each. So, for $50 extra, you could turn a PLL exciter with missing boards into a working unit. These prices may come down depending on how many we can sell. (You know, the more you make the cheaper they become.) We *are* taking pre-orders at this time. If you don't want to wait for the audio processors to be complete, we do have a solution using an adapter board and one of our AP-50 modules: http://www.repeater-builder.com/products/ap-50.html The AP-50 runs $50.

As in years past RB will NOT be setup in the tailgating area. (I know, much to everyone's great dismay) My wife Elisha and I WILL be at the show on Friday - all day. I'd love to say what frequency you might find me on, but if things go like last year, I won't even have a radio on me!! For those that REALLY want to get in touch with me, E-mail me privately and I'll give you my cell #. (Did I *REALLY* say that??) We do have plans to stop by Jeff's lounge and hang out for at least a few minuites. (For those that don't know, Jeff's spaces have become the Un-Official RB list hangout whilst at Hamvention) If anyone is willing, we can *TRY* to coordinate some type of dinner on Friday night for list members going to the show. WARNING: It may be a dinner at Bob Evan's in Fairborn or something, but If you're interested, e-mail me. I'll see what kind of response I get and go from there. Most unfortunately, I don't think I can convince Kevin to make the 6hr. drive to join us. :( Be sure and keep an eye open for anyone in a RB hat. (Those that own one should sport them proudly or be summarily shamed into submission) I will also, more than likely, have a RB shirt on, but it probably won't be visible due to the Parka I'll be wearing. (Reminder to get RB logo'd parka for next year!!) Skipp: Sorry, but if I can't remember a simple radio, how am I supposed to remember my helmet tower?? I'm sure a good time will be had by all - at least until the brats kick in!!

I have 1 repeater in my system with 2 RXs: the main RX is at the remote site with the TX, the remote RX is plugged into the link hub at my home.

Re: [Repeater-Builder] Anyone have this happen?
I agree. Here at Repeater-Builder. We use Bomar unless otherwise instructed for all our crystals. I *HAVE* opened the cases of some ICOMs / Elements I have sent for temp. comp. and *YES* they do have capacitors changed. Don't get me wrong I HAVE had some temp. comp. elements from Bomar that would not net after a few years. I attribute this to crystal aging and Bomar has ALWAYS took them back and fixed them at NO CHARGE no matter how old they were. I think all crystal mfg's have had troubles with quality at some time or another. I remember about 5 years or so a few people complaining about ICM's crystals. As with any custom product, things can and will happen with production from time to time. This is especially true with crystals due to their organic nature. From my understanding, just because you grind a piece of quartz to a specific shape, doesn't mean it STAYS that way. Quartz lattices 'age' and change with time. Could you imagine trying to guess how much, and in what direction, a plant would grow in one year; then be able to prune it so it would be the exact shape and size you needed it to be one year from now? Quote from wikipedia: http://en.wikipedia.org/wiki/Crystal_oscillator Due to aging and environmental factors such as temperature and vibration, it is hard to keep even the best quartz oscillators within one part in 10?10 of their nominal frequency without constant adjustment.

Re: [Repeater-Builder] Somewhat OT - an interesting antenna design
Along these same lines Has anyone on this list built / put into practice a Gray-Hoverman panel antenna? How do they perform? Is it worth building one? Double or single? http://www.casano.com/projects/hoverman/index.html I'm about 70 miles from my target DTV market. (Pittsburgh, PA) NOBODY here can seem to get the Pittsburgh ABC affiliate with their current V/U antenna setups. (WTAE4) I have some people that I am helping get their converter boxes hooked up and working. 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.) I'm wondering if a dedicated UHF panel and good UHF only preamp will help the situation. I can get MOST of the other Pittsburgh DTV stations, but WATE's signal just doesn't make it. If you look at their coverage map they are loosing QUITE a bit of territory. http://www.fcc.gov/mb/engineering/maps/images/callsigns/WTAE.gif Sure would be nice to get it.

[Repeater-Builder] Re: True FM MVP - A possibility
A few weeks ago, someone had inquired if GE had ever made a True FM MVP. I don't think they ever did, but would there be a market for such? In the past, I built a board that would allow true FM on an Exec II. (VHF or UHF) This was basically an adaptor for a MII PLL ICOM to mount inside the Exec II radio. The adaptor board contained an AP-50 for bandwidth and amplitude limiting and plugged right into where the EXEC II ICOM would normally go. These adaptor boards are still available for the Exec II, but would there be a market for a similar board for use with the MVP? I know there are several people on this list that just love the MVP due to their size. (Hi Bob!!) I wonder if they ever wished for the advantages of true FM for their MVP's. Cost on these would be in the $100 range including donor PLL ICOM and AP-50. Comments? Pre-orders? HIHI Scott Scott Zimmerman Amateur Radio Call N3XCC 474 Barnett Rd Boswell, PA 15531
[Repeater-Builder] Motorola Starpoint - Good on 2.4G??
In the past few weeks, I have literally fell into some 2.x GHz Motorola StarPoint gear; complete with antennas and feedline. This has prompted my feeble mind to ask some questions: 1. Can this stuff be up-banded to 2.4GHz? If so, does anyone have a lead as to who has done it and how. 2. If it can't be up-banded, can the antennas and feedline be used on 2.4GHz with other WiFi equipment or radios? Is the bandwidth of the 2.x antennas normally broad enough to support 2.4GHz? In its former life, this equipment was used in place of wirelines between EMA sites. They are now using 10GHz VoIP Ethernet links instead. I thought it would be neat to use the old StarPoint stuff to link our amateur stuff together as a backup. Comments, discussions, et all are appreciated.

Re: [Repeater-Builder] Re: 900mhz , DTR, 906 to 923.75 MHz FHSS
It seems under Part 97 rules we could do this!!! Correct!! As long as you run your callsign as the SSID and are within 902 to 928, you can run all the power you want. (up to 1.5kW) A few things to keep in mind: 1. Good amateur practice still applies. (don't run 1.5kW, even though you *CAN*) 2. Your bandwidth is 20MHz wide. Realize that this wipes out a significant part of the band. I.E. 928-902 = 26 MHz of usable band - that only leaves 6MHz of the band left for someone else. Most devices can employ bandwidth limiting. This is sometimes referred to as cloaking or some other name. By doing this, your throughput goes down, but you are helping your fellow hams by only using 5 or 10 MHz instead of the whole available band.

Re: [Repeater-Builder] Good Repeaters for UHF Ham Band
Good Repeaters for UHF Ham BandJohn, I would have to agree with the comments made by Jim Brown in this thread. I would put any 20-30yr old converted commercial gear up against a brand new Kenwood, Icom, whatever machine. There is nothing wrong with properly converted commercial gear. The best benefit is it's relatively cheap to obtain, convert, and service. Parts are easily found out of 'donor' machines. I can understand most clubs wanting a brand new repeater. One that is all nice and shiny when you take it out of the box. However, there is a reason why there are more used cars than new cars sold in any given year. The used cars may not be as new bright and shiny, but they perform the EXACT same function. Would you rather have a restored '82 Corvette Sting Ray, or a brand new Toyota Corolla?

Re: [Repeater-Builder] Broken Rock MT. tower collapse
The tower I dismantled earlier this summer had locks built into the nuts. Engaging the locks was automatic for the tightening procedure. You simply tightened the nuts with an impact wrench. The lock was nothing more than a piece of heavy steel wire (#12??) imbedded in the surface of the nut. The thread end of the wire looked like it had been cut with a pair of side cutters. (it was chisel shaped to gouge better) When they tightened the nuts during assembly, the wire gouged into the threads of the bolt. When we were taking the tower apart, we had to go along with a hammer and chisel and unlock the locks so we could loosen the nuts. It was almost impossible to get the nuts loose without disabling the locks.

Re: [Repeater-Builder] Duplexers
I often thought about using a Rubbermaid product. Here is a deck box: Rubbermaid item #3743 or a vertical storage cabinet: Rubbermaid item #3749 I'm not saying these would be 100% waterproof, but I think they would work well enough. I think the last price I saw on the storage cabinet at wally-world was around $100 or so.

Leaves at least a little room to breath and work around, heat may be a factor depending on the cans you use and may send them a bit out of tune from the hot/humid summer months to the cooler less humid winter ones. Maybe a hinged lid for ease of access and a padlock. Worked a several sites I have seen but just a small box, that may be too easy to blow around, steal, no room to work, but depends on where you are putting it as it is all relative. --- On Mon, 10/27/08, Mung Bungholio [EMAIL PROTECTED] wrote: From: Mung Bungholio [EMAIL PROTECTED] Subject: [Repeater-Builder] Duplexers To: Repeater-Builder@yahoogroups.com Date: Monday, October 27, 2008, 9:14 AM Is it OK to get some kind of storage container or something like that and put my duplexer outside?

Re: [Repeater-Builder] Re: Shutting Down Battery Back up
If you are concerned about your batteries lasting as long as possible when running on backup, I would NOT use a relay. Even at 100ma of current draw, that's a LOT of current in a backup / solar situation. Since the RF PA only draws current when in transmit, (Class 'C') you can hook it directly to the battery all the time when line voltage is not present. This can be done easily with normally closed contacts on a relay that is fed from the AC line. Have a look at the cutout circuitry of this solar charge controller: http://www.solorb.com/elect/solarcirc/spc3/ They use a voltage comparator to do the switching. I would think a circuit could be designed that simply used a 10V zener diode and a transistor to feed the power FET. Probably until you would go through all of that, you could have the comparator circuit built and ready to go. The moral of the story is that a comparator and power FET switch would draw FAR less current than using a relay coil. You could also set the comparator EXACTLY where you want the circuit to turn off. Be sure that the hysteresis resistor is a small enough value so that when the circuit cuts out with the transmitter active, it won't turn back on when the battery voltage recovers. Of course, this could be tailored to taste.

The battery goes to one side of the N. O. contact and the load (repeater?), power supply, and relay coil to the other N. O. contact. The other side of the coil goes to ground via a resistor. The resistor value is determined empirically and should be selected so that the relay will drop out at about ten volts or whatever you decide is the minimum useful voltage. Use a variable DC supply to determine the proper resistance value. You should be able to find a 12 volt relay that needs less than 100 ma. through the coil. An appropriate resistance might be 22 or 27 ohms for this relay. A 1000 MFD cap should be in parallel with the resistor so that when power is restored from the power supply, full voltage is applied to the relay coil for a time to energize it. The resistor also lowers the power used by the relay to a degree. The ubiquitous chatter diode across the relay coil is a good idea as well. I have used this method for several applications at work and it is virtually fool proof. Good luck, Al, K9SI Now the question and I have not seen this talked about I would assume all I would need is a Normally closed Relay and as the Voltage dropped below a Certain Level it would open and just break the connection to the Battery back up , Is this the way to do it Thanks Don KA9QJG Yahoo!

Re: [Repeater-Builder] Re: Desense with DB4060 Duplexer
If the silver plating seems to be scratched, I have had good luck with the products that are used to silver plate circuit boards. I don't recall the product name that I used, but it was/is available from Digikey and such. I merely used fine steel wool to polish the plunger and then used the silverplating kit to re-plate it. Here is one product I ran across in a google search: http://www.cool-amp.com/cool-amp.html WARNING: The silverplating plating is NOT very thick. It won't take much to scratch it back off, but if you lube the finger stock with a conductive lube it will last longer. I have used no-ox in the past, but Cool-amps's Conducto-Lube might be a better choice. I have had no experience with it.
