But in general -- finding another repeater person there in Florida shouldn't be too hard. Key up a local repeater (preferrably 220 since 220 enthusiasts often are more prone to being willing to help one another), copy the callsign, and look the owner/operator up. If they got theirs going, they probably can tell you who tuned up their duplexer and/or put you in touch with that person, right? It's probably them, in many cases. Buy 'em beer, be nice to 'em... they will probably say Come on over, if you sound like the duplexer tuning is all they're going to need to do. If you sound clueless about repeaters, they're going to be wary. Just be honest up-front with them if you don't know what you're doing, and it'll go better. Enthusiasm may not be something they have much of anymore, or they might be the superhero of local repeater help, you just can't tell.

[Repeater-Builder] Re: New 6M Repeater in Central NH
Nate, I fully agree. Many new HAM's get A scanner to monitor the local going ons (Police, Fire Dept's, etc), or In our area, To monitor SKYWARN during severe weather. Many soon discover there is traffic at times other than bad weather and become interested. Maybe they catch A weekly or daily NET. There are many ways to become interested in this great hobby. There seems to be no end to the learning. New methods, new protocols, mixing radio and computer, voice, digital and CW, etc. As for finding LOCAL HAM's, you sure won't do that on HF! I am A fairly new HAM and there are several people at our club who will just about bend over backward to help or teach you. Give you extra unneeded equipment, teach how to make A simple first wire antenna, etc. No Class Warfare Here!

RE: [Repeater-Builder] Cable length for NOTCH cavity?
So... I tuned a spare can as a notch (~19db) at freq X and intend to place it in-line with the Radius in hopes of removing (lowering) the level of freq X getting into the Radius transmitter. A 20 dB reduction should reduce the intermod by 40 dB IF the mixing is happening in the Radius. I hope. I intend to remove the antenna cable from the Radius, plug it into the T at the can and run a double-shielded cable from the can to the Radius. Does the length of the added cable matter? For the most part, no, it won't matter. If you were putting multiple cavities in series, with the notches all on the same frequency, cable lengths would be more critical. As long as the notch cavity is high-Q enough, and its return loss is high at the Radius' Tx and Rx frequencies, there won't be a problem. A more definitive test would be to just stick an isolator (dual stage preferably) between the Radius and the antenna. Key up the Radius and transmitter X, see if your receiver Y hears it. Sure, the receiver is going to be deaf while you do the test, but it will conclusive, and will only take a minute or so to run the test... --- Jeff WN3A

RE: [Repeater-Builder] UHF MICOR Unified Chassis
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.

[Repeater-Builder] Re: UHF MICOR Unified Chassis
Mark, It sounds like you may be missing the modifications on the interconnect boards for and squelch. 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.

[Repeater-Builder] Duplexer
I have some copper pipe that is 6 inches in diameter and about 60 inches long. This came from the filters on a 25 Kw channel 4 TV transmitter. Would these work for a 6 meter repeater? I am thinking that they are a little short in both length and diameter. The feedline for the TV transmitter was 6 inch rigid line at 75 Ohms. I will either make these into a duplexer (is they are suitable) or scrape them for their value as copper. Thanks 73 Glenn WB4UIV
RE: [Repeater-Builder] UHF MICOR Unified Chassis
I was aware that there might be previous modifications. I have 14 of these chassis I picked up from the same source, so I have been comparing them as I go along to watch for issues like that. The only thing I have found so far is two or three of them were modified for connection to an external controller, like a Zetron panel. But I am not using one of those chassis (or at least I don't think). I had some issues with connections to the cards - some of the cards themselves had bad connector pin receptacles, and in other instances the pins on the backplane were bent - but I think I have all this resolved. I'll double check the card edges to make sure the pin seats are tight. I have an extender card to work with, too, so I think that'll help.

Yes, this station was TOTALLY disassembled and scattered to the four winds - chassis, PA and some cards came from one place, more cards from another, yet more cards from yet another place, power supply and cabinet from yet another... I have the station reassembled to the point where it is operating in that it repeats (keys up on receipt of signal and PL) but it does not pass audio. And yes, I am resurrecting it on the freqs it was originally tuned before I make any changes. Right now it's on 462./467. and has one 4-User Control Module (PL decode) card in the chassis. No PL on TX yet... The station has the following cards in the chassis (listed from right to left): Line Driver Station Control Module Squelch Gate Time Out Timer Master Decoder 4-User Control Module Card Am I missing any other cards? 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? 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. (For example JU1 and JU3 are opposite when the manual is compared to the one I have in the shack.) I've also gone to the Repeater-Builder web site, but those pages seem to refer more to the conversion of the station or cards rather than making it work as designed. Maybe once I get it going, then I can think about conversion of the cards that Kevin referenced... Anyway - as far as the backplane goes, I think all jumpers except for JU5 should be OUT. Am I correct? (I currently do not plan on any remote control of the station, but later down the road maybe tone remote operation...) And what about the Line Driver, Squelch Gate and/or Station Control Module cards jumpers? Any ideas? (Kevin, you're the MICOR guru...) Thanks, Mark - N9WYS No virus found in this incoming message.

Thanks Joe! Like I wrote earlier, it appears I'm going to have problems finding the Community Repeater supplement... If you can help me with that, I'd be much obliged!

To be honest, I have not kept up with this thread enough to know what's going on. I have been busy with other projects that are far more important to me than pissing matches about who's repeater is the biggest, or who is better than whom due to his class of license. The intent of this list is to discuss topics relevant to repeaters, their maintenance and general discussion along those lines. I feel that myself and the other moderators are merely here to keep the lists from running amuck. We are not here to stifle any conversation that may contain helpful or insightful information. With the above in mind, PLEASE TRY TO POLICE YOURSELVES!!! We all do this every day on the amateur bands that we are benevolently given reign over by the FCC. We also do this on the commercial frequencies licensed by the FCC. They entrust us with the air, so we as list moderators entrust the list members with this e-mail reflector. This list *has* been SHUT DOWN in the past. This was in a bad era where the whole list went bad and Kevin and I turned the list off for a period of about 4 days or so. I kind of see the same thing stating to happen again. I can see the writing on the wall. Please help keep this list open by trying to keep the topics on subject (or at least close).

[Repeater-Builder] Hard times, hard place (or: Building a small repeater in Brazil)
Hi you all, here PU1BZZ Alexandre, from Brazil Ok, The repeater builder is a great site (and a BIG thanks for all involved, I donated and encourage all to donate at least a dollar. If all of us donate 10 dollars/month to the sites who help us, what a great net this would be, what is 10 dollars in your monthly income?). But I have some special needs I haven't seen in repeater builder, so I came to ask you: How to build a small group repeater in a very tight budget? I'll try to explain Brazil to the ones who doesn't know it: We cannot afford to import duplexers. The raw material to build it is expensive and hard to come by. Also, hardlines are a no-no-buy here. Forget connectors to be used in hardlines. So, how does we build a repeater? We have a small repeater of our local amateur group. This is a radio (yes, ONE radio) with TX and RX stages separated, two antenna outputs, one mast, one antenna on top (RX) and one antenna on the middle of the mast (TX). No grounding, no duplexer, no special measures. Of course, this is way beyond what I can do, but I need to know better what to do. So I have some questions, and these questions could become a tutorial on repeater builder: How to build a thigh-budget-repeater - What is the vertical (or / and horizontal) separations of the antennas? How can I determine the separations, with the sensibility of my reciver and the power output of my transmitter? - In a tower (we got a 6-meters tower to be installed on repeater site soon), how is the RIGHT way to ground it? I have a franklin lightining arrestor. Should I put it on top or on the side of the tower? If it goes on top, where do I put my antenna(s)? - Having a tx and a rx one near another, I'll have enough RF leakage to have desense on RX? - How can I determine the coverage of the repeater? Is there a SAFE computacional way to do that, or will I need to take my car and taking measurements around the 'peater perimeter? - Any homebrew methods to make a repeater SAFE from lightning? A pair of gilettes, one connected to the coaxial hot wire and another to the ground is said to work, but what are the collateral effects? Will it cause arcing from the TX to ground? - Any tips I should follow? Of course, you don't need to say a duplexer would be better, use poly*, have a better budget, buy better radios and like. I do know all of that, but we DON'T have a way to buy a duplexer, poly* and better radios :o) Thanks a lot, Alexandre PU1BZZ (and yes, I take lemonnade from a rock, that is the way things works in Brazil :o))

A 20 dB reduction should reduce the intermod by 40 dB IF the mixing is happening in the Radius. I hope. I intend to remove the antenna cable from the Radius, plug it into the T at the can and run a double-shielded cable from the can to the Radius.

RE: [Repeater-Builder] Re: UHF MICOR Unified Chassis

Listening to all your restrictions, Alexandre, I would try to get access to two towers at least a couple of kilometers (5-10km would be even better) apart and put in a 1.2m or 70cm link between them. Put the receiver on one tower and the transmitter at the other (best if sited on hilltops or tall buildings). If you have a preferred direction of coverage (ideally at a right angle to the line between the towers) you can use yagis for tx and rx pointed parallel and that plus the distance may well cover you. If you cannot get duplexers and don't want to do cross-band (all new radios), then the BIG separation is the cheap way to go.

Re: [Repeater-Builder] UHF MICOR Unified Chassis
You have what were referred to as Community Repeater stations. Before LTR trunking and 800 MHz there were community or shared repeater stations everywhere used heavily by businesses small and large. There is a seperate manual addition which deals with this station. I'll check my files tomorrow. Basically (going from memory) the discriminator signal leaves the RX and goes to the SQ gate and the Master Decoder. Based on which PL or DPL codes are activated on the Four User Modules the signal is either repeated or ignored. Usually the code that is received is transmitted, however it is possible via the Diode Logic and Multi PL or DPL encoder cards to translate the incoming code to another outgoing code.

This is as good a time as any to mention that the Micor Community Repeater Supplement 6881025E55 has been revealed as a prime candidate for full-page scanning into PDF for posting on the RBTIP site.

I bought that manual earlier today from an eBay seller for $14 -- MANUAL #68P81025E55-B. (Eric, I see the reference you sent wants $20 and it's an older manual to boot.)

[Repeater-Builder] Power Supply Question
In the building and testing phase of a system, two power supplies are being used. One for the power amp and one for the repeater/exciter, fan, controller, etc. It appears that a ground loop may be emerging as the culprit in why some sort of oscillation or cycling of the repeater goes on, after the machine is keyed up but before the repeater drops off the air. Is this typical and a sign that only ONE power supply be used for the whole system? Thanks in advance for your input. - Mike

hello i have a icom ic-rp4020 repeater bought it off ebay about 3 or 4 years ago and have just got round to using it only to find i have very bad rx, i get a range of about 40foot with or without an antenna and i even had a big jbeam base station 8 foot long job on it. checked the rx board for dry joints and metered connectors to make sure antenna connector is linked to the board, but before i start working on it i thought maybe someone would know if its a common fault and had a solution, thanks in advance phill hardacre uk
RE: [Repeater-Builder] TEST
Nate ( and all ), Thanks for the welcome. I guess to say that my frustration is/was apparent. It has nothing to do with this reflector but on some outside / other issues. Sorry if that crept into view. I opted to join the reflector and get some help on 'one' of these issues.I have noted a fair amount of info being passed in just the first couple of days of being on. Nothing specifically pertinent to me but it is great to see so much info and suggestions. That's what you want to see.

You might provide more detail, like whether the project is ham or commercial (I guess we can assume ham from the 220 MHz thing) and whether or not you already have a coordinated repeater pair and working repeater, etc... But in general -- finding another repeater person there in Florida shouldn't be too hard. Key up a local repeater (preferrably 220 since 220 enthusiasts often are more prone to being willing to help one another), copy the callsign, and look the owner/operator up. If they got theirs going, they probably can tell you who tuned up their duplexer and/or put you in touch with that person, right? It's probably them, in many cases. Buy 'em beer, be nice to 'em... they will probably say Come on over, if you sound like the duplexer tuning is all they're going to need to do. If you sound clueless about repeaters, they're going to be wary. Just be honest up-front with them if you don't know what you're doing, and it'll go better. Enthusiasm may not be something they have much of anymore, or they might be the superhero of local repeater help, you just can't tell. But with a callsign, at least it's not a cold call to someone... you know they have a working (220) repeater. There's also always the commercial option... a local 2-way shop or similar...

[Repeater-Builder] 6 meter duplexer info wanted
Greetings to everyone here on the list! I am looking to build a 6 meter repeater. I do not have the option for a split-site setup, so I will have to acquire a duplexer somehow. I was looking at buying a new duplexer, but they are just too expensive for the wallet (and the wife!). I thought about building the coax duplexers, but I dont have the test equipment to properly tune them with. I was wondering if someone here builds them for amateur use? Even better, does anyone have a spare duplexer they want to sell? any info would be appreciated. Thanks 73... Larry

[Repeater-Builder] Looking for Aerotron repeater manuals
Hello all. I recently snagged a UHF Aerotron repeater, complete with community PL cards. Being that I have to shift the frequency 21 Mhz, I need to realign the reciever and transmitter. However, I cannot find a manual for either the reciever or transmitter anywhere. I understand that these repeaters are scarce, but hopefully someone out there has a copy of them! Xmit model: 80BT90R (90 Watts) Recieve model: 80BR1 Thanks and 73's Steve WD0EZS
[Repeater-Builder] Receiver for 6 meters
I need a good receiver for our 6 meter repeater. It is on 53.090/52.090. What would be a good radio to look for. Preferably crystal controlled and easy to tune. I am not completely ruling out programmable radios, it's just that they are not my preference. If you have something you would part with I might be a buyer. Thanks, Mick, KB4UPI
