I didn't initially want to step into this, or encourage this discussion. However, some have posted their more thoughtful and comprehensive comments. Therefore, I will post a few of my own here now. Political correctness is a fact of life, but courtesy should reign above all. Living in one culture or another without direct knowledge of the other's mindset, one should be a little more tolerant and not assume eveyone else, those with another opinion, is an inbred idiot. Southerners can Get 'er done! Today, more than ever, we need to help our repeater owners conform to good engineering and good amateur practice. It only takes a few hours of studying a QA resource, followed by testing, to be authorized to put up a repeater. That doesn't necessarily help the newbie repeater owner be fully up to snuff on good engineering and good amateur practice. Has anyone given any thought as to how much interference will occur once the FCC authorizes auxiliary operation on two-meters? We already have quasi-auxiliary operations, such as on-channel remote-bases and VoIP links. Of those, some have been problems, and others have not. The use of tone access should be strongly encouraged.

Nice mix of GE and Motorola stuff. I sort of have the reverse situation with GE receiver / exciter and Moto PA. I have questions concerning the PA selection relays. I assume you have relays at the PA outputs as well as the inputs? What type of relays are you using and do you have some means of preventing them from hot switching while RF power is applied? And if not, what happens in the event of a power failure while the machine is in use? I mean do the relays handle it OK? The PA has been off my VHF repeater for some time due to a relay problem. I need to get it back up there as we took a major coverage hit when it failed. I want to run the tube PA when AC power is on, but need to default to running just the repeater / exciter (20 watts) when on battery backup. I used coaxial relays to handle the switching but the relay on the output of the PA self destructed (I'm guessing as a result of not being able to handle hot switching, though I have no proof that is what led to failure). I am currently trying to come up with some plan as to how to proceed with this situation... Maybe I just need better relays? PA output is about 200 watts.

With all the feedline loss and the distance from the users, we need the 300W Tx power to provide good coverage where the users are. The repeater is also the primary skywarn repeater with wide area coverage of the state and users need to be able to hear the repeater well in adverse weather conditions.

Re: [Repeater-Builder] Solid State VHF PAs (200+ watts of power)
Good comments! The point is there are circumstances that would make running higher power appropriate and not necessarily excessive. I guess the gent can speak to this, but with that much tower, considering the stated use of remote receivers, the feedline loss, and the high transmitter power, I wouldn't expect he was duplexing the receiver on the main transmit antenna. It would be easier to just throw up a primary receiver and link antenna (possibly a dual-band omni) at several-hundred feet on a second piece of CATV line, and let the remote receivers handle the fringe areas. Steve Kevin Custer wrote: .750 CATV hardline has about .66 dB of loss per 100 feet at 68 degrees F at 150 mHz. If he was talking about a 2 meter repeater, 1300 feet would result in 8.58 dB of loss at 2 meters. If he was talking about a UHF repeater, 1300 feet would result in 14.56 dB of loss. If he's running 2M duplex, one could assume about 1.5 dB of loss in the duplexer, add this to the 8.58 dB of loss in the cable and add 6 dB of gain for the antenna, his ERP would be somewhere around 120 watts.

Once he made new cables, his unit tuned properly. Depending on how your harness is made, perhaps you could simply insert some quality elbows in series with each segment. Otherwise, making a new harness should make it tune up properly. I sent him the following text.

Re: [Repeater-Builder] maggiore's service
Too much read between the lines... I did not
say they were technically incompetent. I did not say that their stuff was
crap. I said, "It is impossible to get any real
service assistance from them unless your name is associated with the serial
number." I also stated that they were not replying to my emails, and that
they are not receiving them now because they started to bounce. I no
longer have agood email address for them. Not being able to
communicate with them, I cannot benefit from their $ervice. Maybe I should
have simply said that I had a badcustomer serviceexperience, and
that it is still unresolved. If the Hi-Pro repeater ever craters, the new
one will be a MASTR II.
I could write
more.. however.. Nuff said..

It is not true!
I have been buying repeaters from Maggiore for many years! I sat on his

They have had good and bad repeaters. But they have come a long way and build
one of the finest repeaters on the market today. Say what you will. I have 18
of them on the air they all work just fine.
Comparing there old stuff it was crap. But there new stuff is great!
There service is wonderful.

Re: [Repeater-Builder] Power monitor question
I wasn't thinking of using the 555 as a tone oscillator, but as a timer... You could use it like an activity timer with an AND gate connecting the COS and the power status sensor to time the beep, or just maybe extend the hang-time by some few hundred ms on a power-fail condition. However, that is an interesting observation you make.

Please don't use a 555 - they output square waves which sounds bad and if the TX audio filtering / deviation control isn't what it should be they will cause adjacent channel interference. A simple sine wave audio oscillator is not that difficult - a transistor, a audio transformer, and a few resistors and capacitors. In my initial response I didn't suggest keying the TX PL encoder simply because that may already be in use, and using it for a power fail alert requires hooking some kind of an alarm to a PL decoder somewhere.

[Repeater-Builder] Motorola mobile model M10
Hi Y'all! I have a Motorola M10 that I want to use on a 440 MHz pair for an IRLP station. In its commercial life, this unit was used in a trunking system, has what appears to be DTMF boards under the front cover, and was very likely used with a DTMF microphone. Is there anyone out there who would be willing to either, help me make this a conventional PL radio and program it (mike jack is possibly custom to accommodate a DTMF microphone), or trade for a similar conventional Motorola rig with the 16-pin accessory jack?

Re: [Repeater-Builder] Re: Diamond X500
Coy, There ya go! I thought it was probably a short transmission line since you said something about throwing the antenna off the roof. (he he!) If you do pressurize it, think about using a UV resistant air line.. and not more than a couple of PSI would seem to be enough.. Funny thing about all that silica gel that you see in new consumer electronics packaging.. it's always white.. That's because it's full of moisture. For the silica gel to do any good, it has to be dried. Sure.. you can bake it in the oven or in a toaster oven to make it nice and dark.. but after a while it would turn pinkish and continue to lighten up. Dehydrators like the one you mention will dry the silica gel in the chambers after they have dehydrated the air. This is why they have two chambers, and alternate between them.

I wish I had about 5 pounds of Silica JELL. Oh, while I was consulting for ANDREW Corp, some years ago I had a chance to take a look at their sweet little HELIAX pressureizer.

Re: [Repeater-Builder] Tower Painting and Lighting
I think the old FCC Form 610 asked if you were within 4 miles of the closest point of a runway. I can't say that I recall whether it was statute or nautical though. I guess I'll go look at a new application form, and see what it says. I'm no pilot, but this would seem to mean there would be a symetrical oval around a single runway airport using a 4-mile radius where aircraft might be flying lower and slower in an approach or other type pattern. Schools, homes, gas stations, restaurants, and grocery stores.. all could easily be within 4-miles of an airport. Around here, some of the higher ground along the ridge is unavailable for tower construction because they built an airport about four miles or less away in the valley below decades ago. There are places I'd love to put up a 190-foot tower for a repeater antenna. Heck! Pine trees grow 70 or 80-feet around here in places where you can't put up a tower.

There are some that are both, but only because the owners decided it was better to light it and forget maintenance on the paint, so the paint is faded below standard. But, as long as it's lit, it doesn't matter. There certainly are cases where even below 200' the regulations apply.

Yep. They probably went by the slide slope (or whatever the other side of that is called - the rise slope?) and it came out to 190 feet at that distance. They also required that it have red lights at night as well as being painted! Being painted has nothing to do with the night lighting. It only pertains to daytime - paint or lit. There are some that are both, but only because the owners decided it was better to light it and forget maintenance on the paint, so the paint is faded below standard. But, as long as it's lit, it doesn't matter. There certainly are cases where even below 200' the regulations apply. It's funny to see a power tower painted and lit while others on the same line, even higher in elevation, do not have to be. Same with water towers - the orange and white checkerboards are a hoot.

Re: [Repeater-Builder] BIG battery Astron current limit
Mine is a 450 AH battery bank. I have been using a system, for about ten years, where I have substituted a power supply for a PV panel (solar panel) to feed a solar charge controller, which isolates the power supply from the battery. There are also fuses in the line between every stage, and for load distribution. The problem I ran into is that I just didn't take time to check the site after our recent hurricane related power outage, and the battery discharged to 10.5 Volts. (The job pays the bills, but is sometimes inconvenient during times like these. hi hi!) Anyway, I am now slowly charging the battery using a substitute method. For the long term, I'll probably be okay with a power supply capable of supplying a continuous 25 or 30 Amps. I just need to be sure to get the current limiting thing worked out. Thanks! Steve AA5SG - Original Message - From: Joe Montierth [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Monday, September 27, 2004 2:18 PM Subject: Re: [Repeater-Builder] BIG battery Astron current limit The size of supply you will need are dependent on several factors, such as peak current draw, average current draw, size of battery (in AH), and length of time to reach full charge, after an outage. Usually a single 35 or 50 amp supply will suffice, unless you are running high power or multiple repeaters, or some other type of load. The Astrons really need to be modified (as pointed out below) to change the current limit point to a value that is at, or less than, the continuous duty rating. This can be readily accomplished by adding a single resistor, or a pot, to change the current limit to a lower point. If you don't do this, you could burn out the supply after a long outage, because the supply is running at full tilt for longer that it is designed for. We have used Astron supplies for many years supplying current to an 840 AH battery bank. Before we did the mod for the current limit (about 10 years ago), we did burn up a supply transformer, rectifiers, and transistors. Another thing to do is place a fuse between the Astron and the battery about 20-40% more than the continuous duty rating. This will protect the supply and the batteries from catastophic failure of each other. Joe Yahoo!

[Repeater-Builder] BIG battery Astron current limit
How long would the RS-35M run in current limit at 34 Amps? (This is about 97%.) I have noticed that the internal ammeter sometimes lacks good calibration. As measured on a quality manufactured shunt, 34 Ampspegs out the panel ammeter on the RS-35M, which indicates 40 Amps Max. Anyone have experience with this? Steve AA5SG The below quoted from: http://www.repeater-builder.com/astron/astron-rsbattmod.html A couple of additional comments presented by Joe Montierth One, the 10K resistor can be 1/4 watt or even 1/8 watt, the 1/2 watt is overkill. There is not much voltage across it to generate any heat. Two, depending on the size battery it is attached to, you might want to reduce the current limit point on the Astron. The 35 amp Astron will current limit somewhat above the 35 amp point, maybe around 37-39 amps. If you have it attached to a BIG battery, it can run several hours at the current limit, and burn itself out. If you parallel R4 with a 1K pot, you can adjust the current limit to a point less than 38 amps, usually about 70-80% of the power supply rating is good. Three, always turn the PS "on" before attaching it to the battery. This will keep the internal caps charged up, so they don't have to suddenly charge through the pass transistors on the Astron.

Re: [Repeater-Builder] BIG battery Astron current limit
Well... I have noticed that there are some RS-35M's out there that are heavier-duty than others. I have one with a heavier heatsink, larger xfmr, stud-type SCR, and an extra filter cap. I guess they must have started making them cheaper since... I am running a 40 Amp charge controller. Therefore, I believe I need a PS that will run cool and current limit at 35 or 40 Amps so I can get out of current limiting faster when recovering from a state of discharge after an AC power failure.

Re: [Repeater-Builder] FAA Paint Removal
In recent years, many wireless towers have converted to daytime lighting, which has eliminated the necessity for transmission line painting. The instances I made reference to concerned lease towers, which had transmission lines added when wireless tenants occupied space after the tower had previously been constructed and painted by the landlord. If you will observe the skyline as you drive the highways, you will often see wireless towers that look like they are all black, this being due to the large size and number of lines installed. At this point, everyone hopes that such as these are lit with daytime strobes. If they are not, then they are just waiting for their luck to run out as they are not in compliance. This is where the trouble is found, and not necessarily where a lone piece of half-inch or seven-eighths line is running up the structure. The FCC and FAA are very sticky about the painting of towers that are not approved for daytime lighting, and the interpretation of paint chip vs. weathered structure paint hues is extremely subjective. Also, if you are going to occupy a tower site, be dang sure it's a registered tower if it is supposed to be. If it doesn't require marking and lightning, then it won't require registration. Otherwise, be sure to look for that sign displaying the ASR number to be conspicuously posted. Check Title 47 CFR Part 17 for more details. Search the FCC and FAA web sites for more information.

This is a twist. It is usually the FAA that's giving the grief because of faded paint, which would require repainting in aviation colors.

Yes. I would be glad to see it. The repeater in question is VHF

Something similar to a ComSpec application note would certainly be
welcome

pull the thing down and open it up.
I own a R1, and glanced thru the manuals - there's not much mention of
where the CTCSS output from the TS64 would go to on the board.
I know it's not a standard pinout on my UHF transmitter. As I recall
(from
memory) the output of the TS64 goes thru a resistor, a cap, then is
soldered
to the leg of a resistor on the board. It's definately not a intended tap
point, it's something Paul did in the process of building the repeater for
me with the TS64 when I first got it.
If the transmitter in question is a UHF model, i'll be opening up my
chassis
here in the very near future to upgrade the firmware in my controller, I
can
snap you a macro-sized picture of the tap point.
Let me know...

Re: [Repeater-Builder] 2m repeater IMD issue
This may not exactly fit the circumstances of the current thread. However... I was getting 800 MHz trunking interference on my 447.200 repeater receiver some years ago. I was using a WP 678- R2 duplexer and a Hamtronics LNG-450 preamp on an Exec II. The thing was, there were no 800 MHz station transmitters within five miles of the repeater site. Anyway, it seems that enough of the 800 MHz signals made it through the duplexer pass cavities to cause mixing in the preamp. In the end, the Exec II was really sensitive enough standing alone. I also once knew a fellow who used an LNG-450 on one of his MASTR Pro 460 MHz community repeaters. He had interference from a co-located two-meter repeater. In the end, the ham repeater had to go away. For him, that was more economical from both a time and expense standpoint than solving the problem otherwise. The bottom line is.. Where preamps are concerned.. Caveat Emptor!

This doesn't sound like IM to me, as that would occur regardless of whether the tx was active or not (IM is produced when external RF comes down the TX line and mixes in the PA stages. This does NOT require that the PA actually be making power). Good point. Yes, it only occurs when the 2m repeaters tx is on. Basically, what I see on the spectrum analyzer (connected to the rx port of the duplexer) is several signals coming and going within the passband of the rx cavity (+/- 300kHz approx). I can tune the analyzer to a specific carrier and hear either voice traffic or control channel. All of these signals are around -90dBm at the rx port. As soon as the 2m transmitter is turned off the carriers on the rx port disappear. It sounds more like a classic case of mixing. Have you run all the freqs involved to see where the possibles might be? At this point no. However, I'm in the process of obtaining all of the 800 freqs to do a calc. Yahoo! Groups Links Yahoo!

[Repeater-Builder] Possible Unlicensed Operation in the Deep South...
In recent days (nights), the band conditions being a bit longer for two-meters than usual, we have been hearing some Chinese language stations (..definitely sounds like an oriental language..) transmitting on 146.010 MHz. Such stations are being heard around midnight CDT, plus or minus a couple of hours, coming through the local club repeater here in Laurel MS. I suspect that this may be foreign shipping traffic, either off shore in the Gulf of Mexico, or navigating on the Mississippi River. It sounds like the two operators are communicating inter-ship, and possibly using marine-VHF or other 2-meter station antennae mounted somewhere high up on ship. (Could be ship to shore intercom too..) I have an idea that this may be coming from the Convent Louisiana area, where a Chinese rice shipping terminal is located. If there are any stations down south with rotatable Yagi antennae, please listen and let me know the bearing from your location to the source of any such signals. Please keep a log of times, etc. Also, if you are able to monitor and record these signals, that would be helpful too.. Particularly if you are able to receive them on the repeater input frequency (146.010 MHz.) I appreciate your assistance in this matter. If you are unable to help, then please excuse the bandwidth.

Hi Steve,
Does anyone think it would be

modulator? Just how easy or how difficult might that
be?
You coulduse a varicap, a
tunable inductor, and a capacitor to build acircuit that'sresonant
at the crystal frequency, and that's fairly easy. But such a circuit also
generates an AM component that must be removed, so another transistor stage
isneeded for isolation. That probably meansyou're up to a little
perf-board ('blob') addition to the exciter.
BTW, we think that the GE PM
exciter suffers from a little of the sameinsufficient isolation problem,
but that's another rainy-day investigation.
Incidentally,the
RCversion of a phase modulatoris sometimes
calledareactance modulator,andthe LC version is called
atuned circuit modulator.

I used the modification as above for voice frequencies as well as PL, the difference from the stock modulator was amazing. While the linearity of the modulator 'as designed' is of no concern when only one frequency is applied (like a PL tone) I was surprised to measure quite acceptable response across the entire range from about 10 cycles to about 5500 cycles. Even though the PM modulator in the UHF exciter shows better response because it's multiplied several more times then on low-band or high-band, FM'ing it made it sound so much better. Obviously, a clipper and low pass filter should be implemented when using any modulator capable of deviating beyond the acceptable bandwidth of the particular service/frequency spectrum.Kevin CusterSteve Grantham wrote: Well...

A spectrum analyzer with a tracking generator is the minimum essential tool for tuning duplexers. However, not all spectrum analyzers are accurate enough for such work, and fewer still have enough dynamic range. Most low-end spectrum analyzers have an 80 dB dynamic range, which is insufficient for duplexers that might have greater than 100 dB of isolation. That's where a network analyzer really shines. A return-loss bridge is an important accessory for a spectrum analyzer (it's built-in to a network analyzer), since it allows you to tune for an extremely sharp peak (actually, it's a sharp null) when tuning the bandpass element, thus squeezing the nth degree of performance out of a duplexer. A properly tuned duplexer should NEVER need to be tweaked at the transmitter site. If tweaking a duplexer at the site does improve either the reception or the power output, the chances are good that the spectrum analyzer used to tune it is off frequency. It's also possible that there is a significant impedance mismatch, but I don't want to beat that dead horse! I prefer to use a network analyzer to tune duplexers, because I can easily verify that the jumper cables between cavities are the correct length. In the case of your TX-RX duplexer, you probably should give the factory a call to confirm the cable lengths for the model and operating frequency. Depending upon your location, it may be cost-effective to ship the duplexer to TX-RX, or to another vendor such as EMR, for professional conversion and tuning to your repeater pair. If you do this, do not let anyone touch the tuning controls after its return! The Bottom Line: Yes, you can tune a duplexer without any fancy equipment- but why would you want to, if your objective is to have a first-class repeater? 73, Eric Lemmon WB6FLY timtarhanick wrote: I have a TXRX duplexer I am going to use on two meters. Everything I read, including the manual from TXRX states I need a spectrum analyzer for the tuning the duplexer. Is there any other way besides buying a spectrum analyzer to do the job? Yahoo!

Re: [Repeater-Builder] Need lowband Exec II xciter align instructions
Sometimes component tolerances may all go the wrong way, and will limit a unit's ability to tune up outside the specified band.

Re: [Repeater-Builder] Re: Kenwood TKR850
In the SouthEastern US we have some itinerant repeater pairs on the 440 and 900 ham bands. We don't have those on two-meters, but if your coordination body has not made provisions for portable or temporary repeaters, consider that the flying repeater scenario would fit in well using such planned portable repeater frequency allocations or assignments. Also, repeater hardware on these higher frequency bands would be better suited to flight space and weight needs than equipment on lower frequency bands. A flying repeater operation would be very effective if it were part of a well prepared emergency communications plan. 73, Steve AA5SG - Original Message - From: Dave Fortenberry [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Wednesday, March 10, 2004 4:48 PM Subject: Re: [Repeater-Builder] Re: Kenwood TKR850 You need a portable flying repeater in an aircraft!

By popular convention, most 2 meter Amateur VHF Repeaters use 600KHz offsets. Most 440 to 450MHz Amateur Repeaters in my area use 5MHz offsets, with the transmitter on the lower frequency. I believe much of the country uses the reverse. But we here in Northern California are always the trend setters. :-) Linking 420-425MHz range amateur duplex links in Northern California use a 3MHz offset, as does the 480-490 range T Band repeaters. I believe the UHF tkr-850 would program to a 600KHz offset, but I could see no reason for it when the standard 5MHz offset is the band plan. Many radios and repeaters will operate outside their band edges with retuning and any required programming. The 5MHz split is not set in stone as the offset for many of the vhf 150-165MHz repeaters. I have seen FCC licensed duplex pairs with less than 300KHz spacing to well above 5.5MHz offset. There seems to be no Rhyme or Reason to much of the VHF band offsets, many of the licenses use legacy frequency pairs which are refarmed. Since most of the standard UHF repeater pairs are full in large metro areas, I've been selling and setting up a lot of splinter channel (12.5KHz offset) repeaters. Nothing is normal as the general rule. Your results will probably vary. cheers skipp www.radiowrench.com Larry Simon [EMAIL PROTECTED] wrote: Why would you want the TKR850 to do 600KHz split when it is a UHF radio?

Some preselectors are based upon the physical package used for mobile duplexers, and may work just fine- but they are not flexible. I prefer to use an 8 inch bandpass cavity that I can tune for almost any selectivity and insertion loss that I want. If you have a good preamp with, say, 10 dB of gain, you can set up a bandpass cavity to be extremely narrow but with 5 dB insertion loss, and you will still be far better off (+5 dB) than without the preamp and you will have reduced the vulnerability to overload and desense. At UHF, with a 5 MHz split, the playing field is a lot different from that at 2m, with a 600 kHz split. 73, Eric Lemmon WB6FLY This just does not seem to be a good way to go. If you put a 5 db loss before the preamp the noise figure can not be made up nomater how much gain the preamp has. To top it all off you have to add about 2 db to that for the losses in the duplexer. You let the bp/br duplexer take care of the in band problems and then use a band pass cavity that does not have to have very much loss to take care of the out of band problems if needed. de KU4PT Your use of Yahoo!
