This is not all bat though - you can swap the RX and TX radios and get a station back on the air on no time with no real radio modification. The Micor's require surgery and don't reert easily back to mobiles if needed. One good thing - the cables and control head for up to a 12 channel micor also work directlywith an SRA series syntor.

RE: [Repeater-Builder] Re: 6M cans made from other metals
Skipp025 -Something you did in your project was not as well done as it probably could have been. I am running a heliax duplexer, and it has seen 100° to 15°... no issues so far. Skipp knows all the details... and there is no majic. Perhaps you need to take another look at construction technique besides, if it is all copper, then the expansion coeffeicient is constant throughout... no? If that is the case, then the relationships do not vary... so where is the issue? IMO the biggest issue with a heliax duplexer is mechanical stability... due to bumping, banging, etc... not thermal expansion or growth. I can build them all day long... but if I could find a way to ship them, and have them arrive in-tune I could make a fortune... God knows I am trying.. LOL! Working on that one... just not willing to release the info 'til I KNOW it will be rock solid in shipping.. Yes, I have built and shipped several to another individual I trust, and the curret design just isn't stable. I took a shot at building my own cans, but without the proper goodies to machine the descreet parts, it was a waste of time. And without silverplating everything, you will not acheive commercial specs. The Q of the circuit is everything. While I don't have a lathe, others have contributed time and resources to forward the heliax design. It is a very valid concept, I just need to iron-out implementation. I will say it again to reinforce the thought... it is a very valid concept, don't write it off.

So far we have only been able to put about 1100 to the track, yes there is a ton of computer mgmt going on here and it still leaves a lot of room for improvement but he is running 6.70's in the quarter with a door-slammer. The same can be said for the heliax duplexer. Works good, but it could be so much better! If you don't get serious, you won't realize the benefits. Decimal points count... what more can I say? If I can do all that, surely any of you can build a series resonant notch filter it really isn't that tough guys... there is no majic. You can do this...

RE: [Repeater-Builder] 6m heliax duplexer experiment
I would guess that the resulting impedance mismatch would mess with the current nodes somewhat... In order to acheive peak effeciency, you really want to stay on the odd numbered 1/4 wave current nodes. Not really sure what the effect on velocity of propagation would be.. you will definately need that bit of information to cut the length properly. I strongly suggest sticking with 50 ohm high quality cable. I have found that the little details are what will kill an effort regarding this project.. The series resonant notch is very sensitive, so it doesn't take much of a change to wander from resonance... and you need every dB you can wring out of this design. If I get a chance, I will look into it.. I think I have some RG6 around here... the foil may become an issue as well over time.

Connecting a repeater to a PBXThe repeater is a
commercial repeater, not ham, of course. Sorry I didn't spell it out. Didn't
think it was necessary given the described situation of the proposed access.
This group caters to all repeater types and is not limited to just ham
repeaters. Many (most?) PBXs can restrict access to certain extensions
so that we can control who can access the repeater. This is an internal only
extension that is limited so that only a few internal extensions can call it.
Rather than set up a number of tone remotes, I'd prefer to use our
existing PBX because it affords us greater flexibility.I guess this
group quickly assumes the lowest common denominator when responding to
technical inquiries. :(

positive tactic..

there is a wealth of knowledge in this group. Normally I don't post

"I guess

:("
sigh (not primarily responding to the comment
above)Geez, the lowest common denominator I was referring to was
intelligence, not radio service. Many of the responses I got off list were
bashing me for allowing a ham repeater to be allowed "public access" via the
PBX. Something that I never stated. I got some lovely hate comments to my
initial post were "hey stupid, how are you going to stop Joe Unlicensed from
bootlegging on your repeater. The FCC is going to love you, jerk" types of
replies. I didn't know ham radio suffered from a low level of self
esteem to automatically assume the worst possible connotation in someone's
comments. I was told that this was a better list to ask my question than the
LMR list because there was a better level of expertise here. Instead, I get
abused by list members who assume ham radio is the center of the universe.
Enough about this. Thread closed, I'm done. I did appreciate the very
few civil and informative responses to my
inquiries.

RE: [Repeater-Builder] Sinclair Q-201G duplexer
Eric, I agree.. on the money usually equates to the maximum performace for your intended application. Unfortunately the result is not always within the designed parameters of the cavity and performance from design specs suffers slightly. But if it suits your needs and performance is acceptable, why not? 73 Mike K5JMP www.k5jmp.us -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] Behalf Of Eric Lemmon Sent: Sunday, April 09, 2006 9:32 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Sinclair Q-201G duplexer Ken, I think the stock answer is the one to follow. Actually, since the bandpass tuning on a typical BpBr duplexer is rather broad, while the notch tuning is very sharp, better results might be achieved by tuning the center (bandpass) rod so that the notch is where you want it, rather than looking for minimum attenuation of the pass frequency. Moreover, the pass-to-notch spacing does not always remain constant as the cavity rod is tuned. I'm so used to using a network analyzer to tune a duplexer, that it wouldn't occur to me to tune only half of the functions. There's real satisfaction in getting a duplexer exactly on the money. I guess I don't understand why the question was asked. With the right equipment, a complete duplexer tuning only takes a few minutes, so there's no great amount of time to be saved by skipping part of the procedure. I've tuned quite a few Sinclair Q-201 and Q-202 duplexers, and I find it useful to tune each cavity separately before hooking them together. Very seldom is any tweaking needed.

But I was wondering (and checking my rationale here). in many Bp/Br cavities, the notch tuning actually tunes to a certain freq above or below the pass-tuned frequency. Therefore, if moving the duplexer a meg or two but you maintain the same offset spacing, can you simply get away with retuning the pass freq and, all other things being equal (port impedance, etc), is that all that is needed?

RE: [Repeater-Builder] LMR coax
Tim, The only issue I have had is that if you get any moisture between the braid and foil shield.. you will soon have the million diode marching band serenading your receiver in a duplex environment. It happened to a guy just South of here when a hunk was used in a duplexer harness a while back. Replaced the jumper and all was well again... Also the braid is aluminum, so it is pretty fragile to any twisting etc where it attaches to a connector. Also makes it somewhat difficult to solder to. Use the crimp-on style connectors from www.Fab-Corp.com and provide some kind of stress relief to the connector. Try not to nick the center conductor when you strip it back as it is copper-clad aluminum. I a simplex environment... I love it!

It will do 300 dpi and can also do 600 x 300 (I think). It is slow (maybe 25 seconds or more, I have not timed it), but does a good job. It will interface with Paperport and other programs. It comes with a scan monitor that comes up when you select scan. It is simple to install. I have used it to copy manuals. Some of the Motorola manuals with pages larger than tabloid are not always all one diagram, but instead are pieces and I scan those into tabloid size pieces. Sometimes the schematics just have to be scanned in two pieces and I don't put them back together. I can print tabloid black and white because I have an HP5000 laser printer. It is a 1200 dpi tabloid printer with full duplexer and can print on both sides of the page. I even used the Mustek to scan some x-rays and I opened the top and put a small diffuse light about 2 feet above it. The X-Rays came through pretty good.

What happened in my case was the loop in the PD-1173 can was about 8.5 inches long (8.5 down and 8.5 back up). It seemed that was way longer as compared to what was seen in other bandpass cans. After reading the theory page on Repeater-Builder from John Portune W6NBC, he says it really doesn't matter the size or shape of the loop (as far as the response goes). But as you mentioned, the loop length DOES effect the jumper length required. So after taking a few other bandpass cans apart and measuring their loops, I decided to cut the PD loops down to 3.5 inches. This allowed the jumpers that were the same length as on the duplexer to give a good match. In the end, it was a lot of reading, followed by some good suggestions from this group (and recognizing the need for a network anlyzer). Dwayne Kincaid WD8OYG Not exactly right. The length of the cable between the pass cavity and a notch or pass reject cavity has to be 1/4 wave length including the length of the loop in the bandpass cavity and that is why the cable lengths are different for different cavity brands that have different loop sizes. If the length of that cable is too short for the mounting arrangement, then add 1/2 wavelength (in cable) to that short cable. With a Network analyser, one can see that the length is optimised by viewing the effects of different cable lengths with respect to the effect of the total return loss, insertion loss, the bandpass response (whether it adds properly as opposed to having 2 pass bumps with a dip in the middle like a camel) and the effect of the individual tuning of the cavities. With the proper length cable, one can tune the cavities individually and when placed together, the tuning is not effected. With the wrong lengths, the tuning of the cavities is affected. I am not familiar with those products mentioned but in Sinclair top mounted loops between a Q can and a Pass can, the length is 3 to 4 similar to the feedthrough harness end connection length. Life is easier with a Network Analyser. Harold Yahoo! Groups Links Yahoo!

I wouldn't say they are worthless.. but 1200 bucks was a little on the steep side. I bought 4 complete low-band Micor stations for 30 bucks plus shipping each. And they had the continous duty PA's (which is pretty much what I was paying for, meaning the PA). Speaking of... Mike Morris.. do you want one of the chassis'? Let me know.. direct please. I also have a couple of extra power supplys I would let go of pretty cheap to clear some room in the shack. I haven't even plugged them in, so I have no idea what kind of shape the caps are in... did I mention cheap? A six can duplexer just sold for a pretty hefty sum, but it was brand-spankin' new, and the correct banding. I would try taking offers on the individual pieces... If you don't get any reasonable offers you might even try... lord forgive me... eBay. Shipping the cans will be a nightmare though. Trading up to a real duplexer from heliax notches would have been nice, but I am about hip deep in a 900MHz machine now.

RE: [Repeater-Builder] Re: 6mtr duplexer
Well guys, I have read all the posts so far in this thread... The heliax notches do workquite well, but they are most certainly not plug-n-play. 1) You must pay strict attention to the design criteria, maximum performance is obtained with repeated efforts. Resulting in a refined adaptation of your construction techniques. Forget the silly box on the top. http://65.173.252.47/Six_Meter_Heliax_and_Helical_Duplexer_info/6m_duplexer _page.htm Hollow-out the center and use the outer conductor as your housing. At least it is consistent in dimensions. 2) Tuning is waay critical... a MFJ antenna analyzer just doesn't get it done. Ask the demi-gods who worked their magic on Mount Waco. There is also a little bit of black magic in the works here... you keep at it until you stumble into the right mix. Then you do your darndest to replicate that accident! Make friends with you local comm-shop so they will lend you a network analyzer. Tune the filters in place... more on that in the next bullet point... 3) The heliax notches are inherently unstable in a mechanical sense. Any small shock can eliminate your tweaking efforts. I have dropped them on end just an inch or two, and the notch moved a hundred hertz or so. Now you are on the shoulder of the notch, and make no mistake.. it is a VERY sharp notch. It is something like balancing an ocean liner on the head of a pin.. that is if you truly want peak performance. I have noticed no issues with environmental (varying temps) effects as of yet. Cover the end with a metallic cover... leakage is a killer. I have constructed several sets. Most are in the county landfill! Thinking I would need 4 filters in each leg... I am now down to 3 in each leg and very impressed with the performance. I have not solved the mechanical instability issue as of yet.. still looking for the perfect glass-piston type cap to replace the gimmick cap, and the perfect range for my pair (51.4/51.9). It seems to be a moving target.. or my techniques are just not as disciplined as needed for mass duplication.. yet. And you can forget shipping them. I agree with Skipp... partially.. I think the cost difference is more like 13dB better. The line was free, as was everything except for the roll-off components... maybe 10 bucks there... 40 bucks for good double-shield harness cable and connectors.

That is the great thing about ham radio... so many modes, so many projects to pursue! We have such a diverse hobby that there is something for everyone. I try to practice the old live and let live philosophy... to each his own. I just enjoy building devices, testing them... and refining the design until something else catches my eye. Most of my old projects sit on the shelf gathering dust until field day, or a demonstration event. Then you get to show off your work, and let the new guys (we work hard to interest the young folks) have a peek of just how much this hobby has to offer!! I have ATV gear that hasn't been powered-up in over 3 yrs, but I keep it because I built it from scratch and the kids need to know that you can do anything you want to in life. All you have to do is be willing to work for it. For the most part, ham radio and project building instills these values.. values that seem to be dwindling in our society these days. Build away.. learn all you can. Just don't forget to pass a little along to the new guys. Not ranting, or preaching... Just happy I found the hobby!

I have to side with Joe on this one. Having spent time as an Army communicator in some of the worst $#*!-holes on earth with lives on the line... it is the content of the message that has to be communicated. Not punctuation and grammar. It is not a complex mathematical formulae that you are sending... it is communication. There are many different dialects, but the message is the same. Regardless of how it is conveyed. CW is just one operation mode, there are many others that are just as efficient. Just my 2 cents Tech-class licensee by choice, 26yrs of communications in many formats.

It is the 70-2959-X (X=1 for VHF and 2 for UHF) option. In their Low Band, you could have either VHF or UHF repeater unit, which is actually an 8 channel 1 - 2 watt handheld radio and a controller. In VHF Models, the repeater unit would be UHF. These are added into the main chassis and are considered a trunk mount or remote mount package with control head. The Deluxe control head can actually be attached to the front of the radio to make an all-in-one configuration. Look for Midland Vehicular Repeater on eBay. The 70-3400B is a 40 watt VHF Highband unit, which will tune down to 2 meters and is computer porgrammable. The 70-520CWB is a 110 Watt lowband unit which will tune to 6 meters. Both rigs use 2 separate antennas; no duplexer required. The programming will allow matching a repeater channel to the input channel. When you go in on a specific frequency, it will go out on the frequency matched to that channel. Power can be set to high or low; values determined by maximum output. They have very flexible programming options. Make sure there is a local shop to do the programming for you.

There is not very good lateral strength in a ladder because there is no diagonal bracing like most towers have. You need to think triangles.

RE: [Repeater-Builder] Induced RF on tower and antennas
Ralph, Yes a tower can soak-up energy and bite you... most often this occurs in medium-wave. And it is a RF-burn rather than a shock. I sometime conduct RFR exposure studys for broadcast facilitys.. and occasionally we find things that are hot enough to burn you... but not often above 30 MHz unless you are in the near-field of multiple kilowatts. There have been some cases in the past where a rigger would climb through the aperature of a live antenna wearing an ANSI suit and report that it was smoking!!! That is why un-controlled exposure limit is 100µW/cm^2 for gen public. There have been some interesting FCC citations at Mt. Wilson in the recent past.. try googling Mt. Wilson RF Exposure and see what you get.. it can be a real eye-opener. At first blush it sounds more like a ground fault in your station. Was the feedline completely un-hooked from the station? How often is the feedline grounded to the tower? Are there any AM broadcast facilitys in the immediate area? A hundred feet up, with a hundred feet back down the line is approaching a 1/4 wave at AM broadcast freqs... makes a nice loop antenna for some of them. Try disconnecting the feedline and check for any potential between station and feedline would be my first suggestion.

[Repeater-Builder] antenna's
First thing... this ain't the place for this type of antenna question... there are yahoo groups specifically for this type of discussion. Begging the listowner's pardon... I will address the question at hand... I guess the first to ask is what exactly are you trying to accomplish? You haven't provided enough information to even begin formulating an accurate answer to the question. Taken literally at face value... yes, you can build a splitting/phasing harness quite easily. For those in the know... Please pardon the enormous bandwidth... ;-) Just delete this message now and move on I first considered responding that you should get an 11m radio to go along with the 11m idea. But that is rude, and un-called for... so I have just sat idly by to see how far this would go. It looks as though it isn't going to die a quiet graceful death, so here goes... Phased Directional Antennas 101 Your question... Someone has told me their is a co-phasing harness available for two meters has anyone heard of this. to unite two antennas. In the same way truckers do on CB's Thanks You can create a 50ohm match to split by using RG-59 is 75ohm (and is lossy as hell at 2m, but for the sake of argument please bear with me.) cable cut to an odd multiple of a 1/4 wave length combined with a T-connector. Feed the T with standard 50ohm line. Assuming a purely resistive load, the two lines in paralell will present a resistance of approx 37.5 ohms. This is close enough. And I am NOT going to get into complex impedances here. The first thing you need is manufacturers data for velocity of propagation for the line you intend to use... an electrical wavelength is not the same as a physical wavelength.. It will be physically shorter than just calculating a wavelength mathematically. Reason being that no cable is 100% effecient. This is where the velocity factor comes in. A better quality RG-59 will have a velocity factor of something near 82% (0.82). To get to where you need to be.. divide 300 by the desired frequency in mHz.. The result is one physical wavelength. (please pardon the round-off error) 300/freq in mHz= 1 wavelength physical length in meters - ie; 300 / 146.52 = 2.047m multiply this number by 0.25 for the 1/4 wave length we spoke of earlier... 2.047 * 0.25 = 0.512m This is where velocity of propagation comes in to the equation... you now multiply the 1/4 wave physical length by be velocity factor of the specific cable you plan to use... we spec'd RG-59... so the velocity factor is approximately 82% 0.512m * .82 = 0.42m - this is the electrical 1/4 wavelength @ 146.52 mHz using RG-59. Using odd multiples of this number will keep you on a current node, but only at 146.52 mHz... if you change freq by very much, the whole thing falls apart. Staying on the current node is important... you will just have to trust me here. As I am not going to delve into the reason's why. Figure out how much distance you need to cover between the 2 antennas... how far from the split to the connector at the bottom of the antenna. For this discussion, we will use 5 meters (physical) for each half of the phasing harness to get to the antenna from the T. We will call this the cable run distance. Next divide the cable run by the 1/4 wave electrical length. 5 / 0.42=11.9 quarter waves we need to stay on the current node by arriving at an odd multiple, so we must add another 1/4 wave electrical... So each cable run will be 13 electrical quarter waves (odd number to stay on the current node) 13 * 0.42 = 5.46m or 17.91 feet. Cut your 2 cables to exactly this length, connector tip to connector tip. Attach one end to your antenna, and the other to the T connector, then use 50 ohm line from your radio to the T connector. This arrangement (method) is only good for the specified frequency used in your calculations. If you change frequency very far.. the match will not be good, and that will piss your radio off ... so to speak. Bad match = power fold-back or even worse smoked finals. Now you have a phasing harness with 0° phase shift that will present a workable load at 146.52 mHz Placement of the antennas presents a whole new world of problems. Assuming you place them exactly 1 wavelength apart (rough guess for mounting on each mirror of a vehicle), fed in phase unity current, the resulting pattern will resemble a squashed four-leaf clover, with most of the signal being radiated to the sides (I tried at first to send this with a EZ-NEC plot of the pattern, but yahoo threw-up. If it is desired, contact me directly.. And I can supply bothe the file and the plot) So I guess my question now is WHY? Is this a coolness thing? You will most likely acheive around 2.7 to maybe 2.8 dB of gain.. and a horrible pattern... Why not be cool by being smart and buy a higher gain omni antenna? You will be more effecient, avoid all the headaches, and the pattern and match

If the antennas are 50 ohms and you feed them with odd quarter waves of 75 ohm coax, the impedance is transformed to 100 ohms... divided by 2 at the T connector is 50 ohms, not 37.5. In theory I agree with the comment about not moving too far from the design frequency, but in practice I suspect it will be a little more forgiving. I have built phasing harnesses this way for 2 and 4 dipole arrays (base / repeater antenna) and they cover a fairly wide range before the impedance gets out of hand.

I take a day off and the killer antenna deal blows right on by me... Scala Kathrein Antennas are just killer. I use them in Commercial and Amateur Service all the time. I paid over $600 for the last 5 dbi version of this antenna and they take min 4 weeks min to get from Germany (where they are made) through Oregon/WA. Who ever got the antenna better be real happy. By the way, the mentioned band of operation is a special order, most often ordered for the Canadian Public Safety/Commercial Market and semi limited US Amateur purchases. This antenna is one of the few fiberglass models of this type... spec for an honest full 30MHz bandwidth, which actually do what the mfgr promises.

RE: [Repeater-Builder] Repeater, service monitors and other stuff for sale
I just did a quick advanced search on QRZ for the name heiniger... returned 0 results. It doesn't mean that he isn't legit.. but I wouldn't send any money until he answers. mike K5JMP -Original Message- From: Mathew Quaife [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 08, 2005 8:23 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Repeater, service monitors and other stuff for sale Might be that he is busy with his job enhancements, I also emailed him about the TM-7V radio as well, and have not heard anything. But you are right, identity would be a necessity now.

I never really had too much of an interest in the radio or electronics thing like my father did, so I never was licenced and now I really have no use for the items. On top of things, the company that I work for is promoting me but I have to re-locate. Rather than haul this equipment across the country, stuff I dont use anyways, I've decided to sell it to lighten the load. I had a yard sale, sold a pile of the little items like mobile and hand held radios, tuners antennas - even the tower sold. Some of the people that came by told me to post the stuff on E-Bay, others mentioned yahoo groups and others mentioned newsgroups. Since E-Bay charges an arm and a leg, and I need to get this stuff out of here ASAP, I'll try the groups. To make this stuff go quick because I don't have much time to mess around with it, I've priced the stuff cheap to make a quick sale. Also, I'm prefering to use Paypal rather than Money orders, just because of the time issue. As an added bonus, All items SHIP FREE with insurance and a tracking number. You pay just the amount of the item(s) you want.
