Re: [Repeater-Builder] Re: Re-Tune a Vocom Amplifier
I have one of these amps and the paperwork from cresend/vocom on how to tune/align. I will try to locate and scan for the group. It isn't that hard to tune. The instructions are clear. I seem to recall that you will need 2 bird watt meters, a 50 ohm load capable of handling the power and 13.8vdc power supply with amp meter. 73 Norm - Original Message - From: Repeater-Builder@yahoogroups.com Repeater-Builder@yahoogroups.com To: Repeater-Builder@yahoogroups.com Repeater-Builder@yahoogroups.com Sent: Thu Jul 22 23:18:55 2010 Subject: [Repeater-Builder] Re: Re-Tune a Vocom Amplifier Excellent...

[Repeater-Builder] adding a 3/4meter repeater to my site?
I am sure this is a stupid question, or it seems so to me, but I can't find the answer anywhere. I am thinking about putting a 440 Mhz repeater (or link) for Packet at my 2M repeater site. Can I use the same coax and antenna (multi band) or do I need a complete seperate run? Hoping to save a chunk of change ;-) Of course I'll need seperate cavities and /or duplexer. Thanks, John K2QY
Re: [Repeater-Builder] adding a 3/4meter repeater to my site?
John, You will get as many positive answers as you will negative. That said, the proper way would be 2 antennas and 2 runs of coax. If you already have the dual band antenna and want to go that route there are several things to watch out for. What is the power rating of your antenna? If you have 2 repeaters putting out 100 watts into an antenna rated at 100 watts, you will damage the antenna. At the ground end, you will need a diplexer to split the single run of coax into one for each repeater. The diplexer will have the same power restrictions as the antenna. Without keeping these two restrictions in mind, you may spend more $$ the second time around.

RE: [Repeater-Builder] Strange VHF PA with power resistor setup problem
Ross, Looks like a standard PA on the GE MSTRII. The other board looks like a audio filter or audio generator. These are used when the receiver is attached to a voter. It produces the 1950 Hz tone when the receiver is not receiving a valid signal and goes away when a valid signal is received. I hope this helps.

Came out of a VHF repeater with a IDA control shelf. The problem with the PA is intermittent power output. Runs 10watts or 100watts depending on if you just smacked it or not. I saw it arc above the second driver after a smack when it came up to 100 watts where it looks like there is a lack of solder.

[Repeater-Builder] Repeater transmit levels at the receiver?
Hi folks, Still working on the hardline duplexer for 6 meters, and have some data I'd like to run by you guys. Running 80 watts out of a Micor tx into the TX bank of cavities. With test equipment, get about 100dB notch. (shows 50 watts into dummy load as well).. have about 1.5 - 2dB loss through them. Ok, now I hook the spectrum analyzer up to the receiver port, and I see about -55dBm. 50 watts = +47dBm, minus the 100dB notch = -53dBm that is pretty close to what I'm seeing at the rx antenna port. Question is: Should this good enough for a low band micor receiver? Thanks, Tim W5FN

RE: [Repeater-Builder] Repeater transmit levels at the receiver?
Ok, now I hook the spectrum analyzer up to the receiver port, and I see about -55dBm. 50 watts = +47dBm, minus the 100dB notch = -53dBm that is pretty close to what I'm seeing at the rx antenna port. Question is: Should this good enough for a low band micor receiver? Thanks, Tim W5FN Yes, should be good enough for even 500 kHz split. However, at close tx-rx offsets, transmitter noise is often more of an issue than carrier supression, so test your duplexer backwards to make sure you have the same isolation in the other direction. And don't forget the noise foor on 6m is usually pretty high, so even if you have a trace of desense on the bench using a dummy load and lossy tee, you may not even notice it in the field. --- Jeff WN3A

[Repeater-Builder] Repeater help needed in Western VA
Fellows, I haven't had any volunteers yet, so I thought I would plead again: I am writing on behalf of a customer of mine. He bought a 2M repeater from me and is having trouble getting it going. I think he needs help getting his duplexer tuned and cabled correctly. He seems like a nice enough fellow. He had a fall some time ago that fractured most of his limbs. Needless to say, getting around is difficult. At any rate, he has a decibel products 6-8 cans that he is only getting about 60dB of isolation out of. (A local radio shop tuned them. HIHI) The local guys around him seem incredibly inept when it comes to repeaters. One of them even told him that his repeater was upside down because: that's not how my radio is programmed!! (upside down between a mobile and repeater setup) Is there any list member, or does anyone know someone, that is close to Big Stone Gap, VA 24219 that might be able to give this fellow a hand? He looks to be about 2 hours NE of Knoxville. I'm sure reasonable compensation would be offered. I'd help him out myself, but it's a 7 hour drive for me.

Re: [Repeater-Builder] OT: Licensing Exam Info
How much do you know about electronics and radio in general ? If to some extent , the exam is no problem. Even less if you have a good memory. There are 3 classes now. The Technician, General. and Extra. For each one there is a pool of about 300 questions and answers . That is the exect questions and answers for the test. To take the test you have to go to where there are 3 or more qulaified examiners. Some ham clubs give the test every so often and many times at hamfests (flea markets for hams). Each class requires about 30 to 50 questions to be answered. they are all multichoice. I think it is 70% for a passing grade. When applying for the test , apply for all 3 classes.. It is usually all the same price. If you pass the first one, you can take the next higher test. There is no code (CW) test now. Somewhere around $ 15 for the test now. After you are licened , it is good for 10 years and does not cost anything to renew it. That $ 80 is way too much. You can buy books with the questions and answers or download them from places on the internet. Go to www.qrz.com and look for the prictce test. Give it a try and see how well you do. I have been a ham for over 35 years and can usually hit about 90% on the practice test on QRZ.com in about 10 minuits for each of the 3 tests. I do that from time to time when I hear how hard some say the test is. If you want to learn something about ham radio, go to arrl.org and get one of the handbooks. Think they are around $ 50 now. You can go to e-bay and get some that are a few years old for only a few dollars. Also at arrl.org look at the amateur rules. Part 95 of the FCC rules. Ham radio rules usually differ from comercial rules in that mostly the ham rules state what you can not do instead of what you can do for many parts. If you have your comercial license, the test is similar and should be no problem.

To take the test you have to go to where there are 3 or more qulaified examiners. Some ham clubs give the test every so often and many times at hamfests (flea markets for hams). Each class requires about 30 to 50 questions to be answered. they are all multichoice. I think it is 70% for a passing grade. When applying for the test , apply for all 3 classes.. It is usually all the same price. If you pass the first one, you can take the next higher test. There is no code (CW) test now. Somewhere around $ 15 for the test now. After you are licened , it is good for 10 years and does not cost anything to renew it. That $ 80 is way too much. You can buy books with the questions and answers or download them from places on the internet. Go to www.qrz.com and look for the prictce test. Give it a try and see how well you do. I have been a ham for over 35 years and can usually hit about 90% on the practice test on QRZ.com in about 10 minuits for each of the 3 tests. I do that from time to time when I hear how hard some say the test is. If you want to learn something about ham radio, go to arrl.org and get one of the handbooks. Think they are around $ 50 now. You can go to e-bay and get some that are a few years old for only a few dollars. Also at arrl.org look at the amateur rules. Part 95 of the FCC rules. Ham radio rules usually differ from comercial rules in that mostly the ham rules state what you can not do instead of what you can do for many parts. If you have your comercial license, the test is similar and should be no problem. -- From: La Rue Communications laruec...@gmail.com To: Repeater-Builder@yahoogroups.com Sent: Fri, July 23, 2010 12:43:34 PM Subject: [Repeater-Builder] OT: Licensing Exam Info Good Morning All - I am looking to take my Licensing exam and get my HAM / Radio Operator's license.

Re: [Repeater-Builder] OT: Licensing Exam Info
Just want to clarify one thing. As I read the orignal post, I understood it to mean that he was inquiring about taking the test on line which is not possible. All tests are administered through Volunteer Examineers... You can find a local group of VEs and testing schedules on the ARRL web site... The only fee is for the examination itself and is less than $10. Once you receive the license it is good for 10 years and renewable after that. Just a small clarification in case that is what the was being asked.

A wrong setting wouldn't interfere with PTT. I think there was a drawing in the manual linked below, illustrating the locations. Are you grounding the PTT line and have reprogrammed the radio to allow external PTT? Regarding the speaker, are you getting the audio you need from the connector, but you want to disable the internal speaker? Maybe inserting a 3.5mm plug in the speaker connector on the back will mute the internal speaker. You could put a resistor inside the plug to provide a load.

At 01:19 PM 07/23/10, you wrote: Hey Guys. I was looking at the schematic for the above mentioned speaker (thank you repeater builder site) and I had a few questions. If anybody's interested it's here: http://www.repeater-builder.com/motorola/genesis/pdfs/nsn6054a-68p81108c39-o.pdf First, does anyone know where to find a replacement for the 5184320A99 dual op-amp labeled U1? I'd look in the National Semiconductor products manual that covers automotive audio products. That schematic resembles what I saw in an early 1980s app note for a car stereo receiver. LM187something. Secondly, Is this op-amp basically being used as a buffer, preamp, and inverter? Both halves are being used strictly as an inverting buffer for out-of-phase audio. Look carefully at the schematic and remember that nothing in the input circuit is ground referenced - the audio input (from the radio) is balanced audio (both are sides hot, 180 degrees out of phase with each other, and there's an implied / virtual audio ground) in the middle. Each side of the circuitry driving the speaker is a mirror image of the other, just like the incoming audio is a mirror image compared to the virtual ground. Thirdly, what on earth are pins 3, 4, 5 and pins 10, 11, 12 doing? I have never seen so many pins on an op-amp tied together. If that chip is the one I'm thinking of its capable of about 2 watts per channel on it's own. That takes some heat sinking. Probably a heat sink for the final transistors inside the opamp. And if you look closely, pin 1 is audio ground, and pins 3,4,5, 10, 11 and 12 are power ground - and those are switched to ground by Q3, which is driven by the squelch circuit in the radio. Thanks!

Re: [Repeater-Builder] adding a 3/4meter repeater to my site?
And watch the frequencies - don't have a 147.18 output and try and run it with a 441 input. Or a 146.64 output and try and run it with a 439 link channel. All it takes is one third harmonic to ruin your whole day. Mike At 06:14 AM 07/23/10, you wrote: John, You will get as many positive answers as you will negative. That said, the proper way would be 2 antennas and 2 runs of coax. If you already have the dual band antenna and want to go that route there are several things to watch out for. What is the power rating of your antenna? If you have 2 repeaters putting out 100 watts into an antenna rated at 100 watts, you will damage the antenna. At the ground end, you will need a diplexer to split the single run of coax into one for each repeater. The diplexer will have the same power restrictions as the antenna. Without keeping these two restrictions in mind, you may spend more $$ the second time around.
