Since it's just not calibrated for whatever that impedance might be, how can it be accurate? The Bird is set up so that the ratio of voltage and current that are detected work out to the power at 50 ohms. When the line is not 50 ohms that voltage/current ratio change that the meter detects.

Hi Kevin: Regarding temperature, our club has a site, no A/C or heat, where temperatures inside the shelter can get below +20 deg F in winter, and well over 130 deg F in the summer heat.

Invar is a nickel-steel alloy that exhibits about 1/10 the thermal expansion as a common carbon steel counterpart. Invar is used to make the tuning rod - many times it's threaded.

Re: [Repeater-Builder] Coax length, etc.
Some related comments, if you don't mind. Temperature changes seem to be the biggest "detuner" of largely mechanical devices like cavity duplexers. We often send our repeaters off to live in less-than-ideal environments, then expect cavity input/output impedances to remain as we measured them in the shop? Don't think so. IMHO, we're making the same mistake I made in a post the other day, saying "VSWR" when what we really mean is "reflected power" as indicated on a meter. Jeff is correct, VSWR along a transmission line doesn't change if source, load and line impedances are stable, the ratio remains the same. What does change, and what is affected by line length, are actual impedances along the line under not-so-perfect-or-stable conditions; the actual impedances along the line change but the ratio does not. For example, 100+j0, 25+j0, 40+j30, and 40-j30, are different impedances yet all exhibit a VSWR of 2:1 in a 50-ohm impedance system. Voltage is proportional to impedance. We can't really have a voltage standing wave ratio greater than 1:1 without a voltage differential, and that really can't happen if impedances along the line remain the same. Our friends at Agilent have put together a Java applet demonstrating what happens along a transmission line. Maybe you're aware of it, it's really kind of cool. The applet allows you to change the load impedance of the model and see the changes, so have fun with it. http://education.tm.agilent.com/index.cgi?CONTENT_ID=6 Our in-line power meters, like our trusted Bird 43, do not directly measure power. They're really voltage meters calibrated in watts at a specific impedance. That's why they can be fooled into displaying an erroneous reflected power reading, perhaps lulling us into a sense of security that the VSWR on the line is acceptable when it may not be. With most transmitters I'm familiar with, a "high VSWR" condition is detected from a reflected RF sample from a directional coupler at the transmitter's output, so it's not a "real" VSWR measurement per se, it's a voltage measurement. Worse, these couplers tend not to be very selective, so out-of-channel and even out-of-band energy can cause "high VSWR trips" even when our measurements indicate all is well on our frequency of interest. Great discussion, keep it going. If I repeated what was already mentioned, my apologies. 73, Russ WB8ZCC On 8/14/2010 12:53 PM, Kevin Custer wrote: Jeff DePolo wrote: Because the impedance is not matched between the transmitter and duplexer, the 'apparent' loss of the duplexer is greater than the manufacturers stated loss of the duplexer. Changing the cable length is not changing the loss of the duplexer, it's changing the power that is accepted at the transmitter port of the duplexer by matching the output impedance of the transmitter to the input impedance of the transmitter port of the duplexer. But if the duplexer is tuned to 50 ohms, and the cable is 50 ohms, varying the cable length isn't going to change the Z seen by the transmitter. Or are you suggesting the duplexer is purposely de-tuned from 50 ohms? Purposely, accidentally, by lack of good design - people not having the right equipment to tune it correctly - whatever. And also that by varying the cable length between the transmitter and the duplexer that you can vary the reflected power on that same line? Yes. With all due respect, that's not possible, regardless of what the Z is of the duplexer. The only time it could have an effect on the reflected power would be if the transmitter/PA were spurious, and the amplitude/frequency of the spurs changed with varying load Z, and I think we can both agree that if that's the case, we have bigger fish to fry. And this is where I believe the duplexer manufacturers are covering their butt. They don't want the problem with complex reactance presented by the duplexer to be their problem. Not that I don't agree, because it's usually the transmitter that is really at fault. Joe Ham buys a new duplexer and hooks it up to his 110 Watt MASTR II repeater and gets 50 watts out the antenna port. He does his homework and realizes that he should only be loosing 29% with the 1.5 dB of insertion loss stated in the paperwork - but he's loosing over 50%. The duplexer manufacturer supposedly engineered and tuned it for a 50 Ohm system. He knows that the cable he connected to the transmitter is good, because when he disconnects the end going to the transmitter port of the duplexer and connects it to his Bird 43 terminated with a good load - it reads 110 watts. Now, is the transmitter becoming spurious and the cable length being changed in length satisfies the match between the dup

That's because there are as many "rules" as there are thumbs. ;-) I don't know about anyone else, but I can tell you about the highly scientific method I use. I start with a multiple of 1/2 electrical wavelength and trim as necessary. I'd stay away from an odd-multiple of 1/4 wavelength in this application... no good reason, just because (black magic and all that). Try cutting the transmitter-to-duplexer line using the receive frequency length, and vice versa. If that doesn't work out, you can swap them. I know, on a 2m amateur system, the length difference is about 1/4". In that case, make a cable 1-2" shorter and see what happens. An alternative is to use multiple short lengths of coax connected together to find a "happy" length, then replace with a single coax cut to that length. As I said, highly scientific. :-P 73, Russ WB8ZCC On 8/14/2010 2:59 PM, Ross Johnson wrote: So will someone post a simple rule of thumb...

Re: [Repeater-Builder] Coax length, etc.
Jeff was correct to question. I was vague. What I should have said was indicated reflected power, not VSWR. But good luck trying to determine an accurate VSWR based on erroneous reflected readings. Let the boo birds squawk. Keep questioning, Jeff. 73, Russ WB8ZCC On 8/6/2010 1:07 PM, Steven M Hodell wrote: Grab your Smith chart!

I don't know what that's supposed to mean. The VSWR on the line is the same no matter where along the line you measure it. If you're using a meter that reads a different VSWR depending where on the line you put it, you need a new meter... --- Jeff WN3A

Hi guys.. This is a good thread.. I've been wondering about the decibel UHF harness for a long time. SO.. If I'm reading Chuck right, the DB UHF elements are 100 ohms.. Correct me if I'm wrong, but doesn't this mean I could pull 2 of the elements off a DB408 and make a DB404 by simply connecting the elements by equal lengths of some good 50 ohm coax to a T, and attach a 50 ohm feedline to the T??

RE: [Repeater-Builder] COR on GM300 8 channel reciever
Hello Henry. I believe the COS on the GM300 is active LO. Open collector.. Try using something like a 10K pull up resistor tied back to 12v. Then, when the receiver hears a signal, the voltage at the junction of the 10K and pin 8 should go from 12v to near 0. Set the ICS controller to use active LO COR.

RE: [Repeater-Builder] Help with Motorola Radius M120 - Intermittent Recieve
Hey Scott. Thanks for writing back. You did some work for me not too long ago. I sent up a spectra-tac receiver that you retuned for me while Kevin was busy somewhere. We swapped the vibrasponder tone element too. I needed 131.8, and you took what was in it and put that one back in.. Remember? Anyhoo... I got this unit about a year ago, and it looked brand new.. Not a scratch on it. Still had that new smell too. I employed it as a IRLP link radio. It's a 10w unit. I'd often try to operate the IRLP node and it would not respond. Turned out to be this unit's receiver. I opened it up last nite. Looked totally virgin inside. I cleaned the connectors where the boards(top and bottom) attach to the chassis. I had to take the lid off what I'm assuming is the VCO compartment to get at a couple of screws to lift the board. It's the shiny lid that presses down over a couple of sections inside the radio, correct? I'll open it up again this evening and take a measurement at the test point you indicated. I'll assume I don't need a signal present to make this measurement. Might be good if you could give me a pointer to location of the RX VCO coil too, so I can tweak if it's out of spec.. Is it labeled? What voltage would be considered acceptable? 7 +- 2v or so??? It really doesn't seem temperature related. The unit operates in a climate controlled room. I may send it up to you for a look if I can't make any headway, if you work on these... 73s, and thanks again for writing back.

An LO that was off would rear its head as sounding off frequency or poor sensitivity. I have had some problems with the LO crystals drifting as of late, but I don't think that is your problem from the description you provided. At any rate, the second LO crystal frequency is 44.645 NOT 45.645. The IF frequency is 45.10, so 45.100 - 44.645 = 455KHz. It sounds to me like you might have a broken/cracked solder joint somewhere inside the radio or that the Rx VCO is going out of lock. Does it seem to be temperature related? If so, that would lead more toward the VCO. You can open the radio and VCO compartment and see what the voltage is on the test point marked "SL." It should be around 7v or so. If not, you can adjust the Rx VCO coil to get it more in-line where it needs to be.

[Repeater-Builder] Re: Solar Power
Hey Tim, The Santa Fe Amateur Radio Club has opperated a solar powered repeater site for over 2 decades. Here is the link to their repeater site: http://www.w5sf.com/repeaters.html Its the Elk Mountain site. The site was initially a FS repeater site and using automotive batteries and 2 solar collectors. In the picture, is the new building and tower, the old building was a Montgomery Wards type metal shed and a rohn 35 tower. The tower came down during one winter and was replaced with a self supporting tower, and a pre-fab building. Ofcourse its over 11k ASL. At times we have had snow covering the panels and the repeater was dead until the sun recharged the batteries. Thankfully we have a wind gen up there now so the batteries have a constant supply of energy. The current site holds; APRS node, FS repeaterX2, FD repeater, VHF Ham RepeaterX2, and a UHF linking repeater. The power side of it; 1500W Wind turbine, ~6 Solar collectors(cant remember the total, i think six), charging system, and the battery bank consists of 12-2V 1480AH, running two pairs of six batteries(12V). Each battery weights: 250lbs. Recommendation for any solar site is: armor plate your power system. 1/2" plate is what we use around our batteries.

Re: [Repeater-Builder] Best Controllers
Hi,all Pac Res is still there and makes several, some ham-bound. We have 3 of the RI-300 series on CARA and they work acceptable. However, programming is very difficult and there is no real-time clock so whenever there is a power bump, the controller sends a "time not set" message with every id. In the programming, the code doesn't wrap around but merely steps onto the next line replacing whatever was there. A trap which is not difficult to avoid if you know it. Either put several calls to another address or plan ahead and leave some blank lines between each command set. Learned the hard way.

Here is how my DB-224 was done. You mount it one wave length off the tower at the transmit frequency. Point all four dipoles at the tower.

He said they still have the two meter DB but when they sell the rest of the ones in stock that is it for any Ham bands. They will not order them 50 at a time as we Hams do not buy many of them to make it worth it for them.

Re: [Repeater-Builder] UHF ham band offset dipole array availability
DB and the Ham cut. There new policy is you have to buy 50 of each antenna to get it in the Ham band. you can still get the DB-404,408 and 420 in the Ham band as long as the dealer you are dealing with is welling to buy 50 of each and sit on them till the next Ham buys one.. It is the same way on the two meter cut antennas from DB a well. Thank goodness there are still dealers out there that will still stock Ham cut antennas.

Re: [Repeater-Builder] D B Products 224 Vhf antenna Question
I had a DB-224 cut for 151.955 from a local school district on 147.315 for many years. It worked just fine. I replaced it about a year ago with a new DB-224 cut by the factory and it does not work any better then the one cut for 151.955. I could have saved a few bucks and left well enough a lone. The bottom line is it should work just fine if you do not go to far down the band. At 147.315 the SWR was flat and looked good on the site master.

[Repeater-Builder] TKR-850
Hello All, If you plan to use a Kenwood TKR-850 below 450 MHZ it must be ordered or tuned to work there. My Kenwood dealer set mine up and it works just fine. Ver twos will do 40 watts all day and night. Very best of 73, Russ, W3CH. Yahoo!

Re: [Repeater-Builder] Coax run
A few things. RG-213 is single shield RG-8 coax so that would not be good. Keep in mind that Times is selling coax. It is not as much the shielding but the fact that the shield and the foil move and cause noise in your system. It has been talked about time and time again here on RP. Good luck, Russ, W3CH. Yahoo!

Re: [Repeater-Builder] 220 Mhz. repeater
Do your really build repeaters? Converting a GE or Motorola is not building. Is it? I have done my share of Master twos and Micores but I did not build them. Just moved them into the Ham bands and maybe duplexed them but I did not build them. Motorola or GE built them. I did move a Johnson or two as well. So before you get up on that soap box that you are building a repeater think about it. You are not building a repeater you are buying an old GE or Motorola that some one else built and adding to it. Or moving it into the Ham bands. Just my two cents. Converting is not building! Very best and a good Easter week end to all. I will be away so I will not even get to see the flames from folks saying they build Motorola or GE radio's you are only kidding each outer. 73 Russ, W3CH, - Original Message - From: "Dexter McIntyre W4DEX" <[EMAIL PROTECTED]> To: Sent: Thursday, March 24, 2005 9:04 PM Subject: Re: [Repeater-Builder] 220 Mhz. repeater > > Perhaps the repeater buyers would like to start a "Repeater-Buyers" > group and leave the technical challenges to real repeater builders. > > Dex > > > > > > Yahoo!

Re: [Repeater-Builder] Re: portable/mobile GMRS repeater antenna
Hello All, I can say that I feed my antenna on my Port-a-peater from the duplexers to the antenna with Beldon mil spec. RG-214/U it is silver and I use type "N" connectors on it, the duplexer is TX/RX and of Crosse the repeater is a Kenwood TKR 850 (non ver. two) it can be installed in about 10 minutes and will run all day. I forgot to add one thing I have a solar battery charger that just lays on the hood of my SUV to keep the battery up. The fold over mount is from Tar Heal antennas in NC and the 20' piece of pipe came from a scrap yard. The whole key is the fold over mount. The DB-404 I had from a early GMRS repeater site before I up graded to a DB-420. The above is my whole system and it works very well.

Re: [Repeater-Builder] Re: portable/mobile GMRS repeater antenna
The little DB-404 works very well we use it for bike-a-thons and walks and so on. We park my SUV in a good spot at the event. And leave it all day during the event. We also have a repeater we install on a high reach for events we need more range. It uses a DB-408 on that unit. 73, Russ Ham, W3CH.

Re: [Repeater-Builder] portable/mobile GMRS repeater antenna

But the short time they where up they worked very well. The only problem I had was we did replace the PL or sub tone Hamtronics encode decode units with CommSpec units.

Hey Will, You will not want to use 9913 for a repeater. You will want to use Hard-Line type of coax. There are many post in the repeater-builders files on why not to use LMR-400 and Belden 9913 types of coax. You may want to go and review them just a bit.

Re: [Repeater-Builder] Re: which kind of cable coax should I use?
I would not buy used Hard-Line type of coax. I know many do but I will not. If you have a TDR and can sweep it then you mite be OK and know that what you are buying is good. Used if they do not seal up the ends some times gets water in it and you just got took. But you can buy new Andrews, RFS or Comscope at a good price from most suppliers. At 50' 1/2 will work just fine. If the Hard Line was a take down there mite be a reason that it was removed from service. Yes you can get some deals on Hard Line some good and some bad. If you can't sweep it beware. Hard line is a funny Animal and can look brand new and be bad. I would still use 7/8's my self. The same place you buy your hard line will have the connectors and most of the time will install them for you.

Re: [Repeater-Builder] A big THANK YOU!
A few points on my new DB-228.
It replaced a DB-224 that had all
the dipoles pointed inland. The DB-228
has all the dipoles pointed inland as
well so no pattern change. The site
sits right on the ocean so any thing
going out in to the ocean is not good
for me. I can say that the DB-228 that
I just had installed works much better
inland. Now I had it install by the pro's
I did not do it my self. Way to much for me.
They did not use the hardware that came
with it. The made in there shop a set of
four brackets. The antenna runs up the
side of a tower and is supported in four
places. top, bottom and two places in the
middle. Unless the Rohn SSV tower folds over
I do not think it will bent. I like the DB-224
and it has done a fine job for two years. But we needed just a bit more
signal inland. To answer any one's question yes 3 DBd made a difference
for this location. I am very happy. I did ask here on the list if any one
had used the DB-228 and every one was correct. It is a fine antenna.
Would it work every where for every one? I am sure it will not. My two
meter site in Chester PA for one. It is two big and will just not work
there.
I would not advice any one to run out and buy one! Unless you have about 45
feet of tower space to run it up on. I do not belive it would work very
well as DB shows it the pictures. But install it mounted in four
places looks like it will work fine. Then again you have all your pattern in one
direction, In this case this is what I wanted and needed. But now I have 12 DBd
going inland.
I hope to get some pictures soon when the WX
clears and we can take a Sunday drive down to
the shore.

Hello,
I
knew about those antennas and have used them in the past, today I installed
the first DB-228 in a long time for a customer. I hope it does well, got
a lot of money tied up in it. I was not real crazy about the mount, it
was a little bowed which made the top antenna tilt a little and also made the
bottom antennas tilt toward the tower. With the bottom brace it helped a
little, at least it made it look OK. The customer is happy, guess that
is what is important.

Hey Dex and the group, Well 3 DB will double as we all know every 3 DB doubles your signal. Yes it did work and no the DB-224 was not broke. It worked just fine and we will use it at one of our newly planned sites. But just like every one said the DB-228 is a monster and will work real well. It does do that. The WX this morning is fog and rain and the repeater is still useable here in Glassboro NJ and it is all the way down in Ocean City NJ. I am very happy and feel it was money well spent. 73 Russ, W3CH - Original Message - From: "Dexter McIntyre W4DEX" <[EMAIL PROTECTED]> To: Sent: Thursday, February 10, 2005 6:42 AM Subject: Re: [Repeater-Builder] A big THANK YOU! > > russ wrote: > > > > I would like to thank every > > one who told me about the DB-228! > > Wow!

[Repeater-Builder] A big THANK YOU!
I would like to thank every one who told me about the DB-228! Wow! You guys where right! I bought one last week and it got installed this morning in Ocean City NJ. I now can work the 147.285 in Glassboro NJ mobile! On the DB-224 I could work it from the base but not mobile. Not is workable mobile. Thank you all for the info! 73 Russ, W3CH. Yahoo!
