RE: [Repeater-Builder] Re: TPN1132A Wireup help and questions
They come out red because your flesh acts like a filter, the camera microprocessor compensates and dials up the lower light frequencies, which happens to be red. Use a piece of white paper - a paper napkin or even a few layers of toilet paper. Do not cover part of the strobe light reflector with something opaque as that will shade one side of the object of interest and the photo will come out with (for example) the right side illuminated, and the left side dark.. One trick I've successfully used is to back off a few feet and then zoom back in so the framing is the same as when you were close with no zoom. The camera flash has to cover more square footage (since the camera is further back) and the amount of light that lands on the object of interest is reduced. After the Canon digital camera I had was stolen I replaced it with another and specifically looked for one with at least 3X mechanical zoom. The one I now have has a 4x mechanical zoom and I've been very happy with it. Last night I took some photos of a Teletek mobile repeater (anyone have any info on them?) and the light source in some was a the camera flash, in others a street light, in others was a LED flashlight, and in the last set was a fluorescent light under a restaurant canopy. I'm amazed at how well they turned out considering the circumstances.

RE: [Repeater-Builder] Re: TPN1132A Wireup help and questions
1500 volts at 1 amp is the same as 1500 amps at 1 volt = 1500 watts only difference is 1 amp requires a small wire and 1500 amps a BIG wire. Power is power no matter how you get there. There should be a plug coming from the low voltage supply to the upper left (from back) of the control chassis. On the upper right there should be another plug with quite a few wires on it. Pictures did not come out as the flash washed them out. I am going there again today hopefully in daylight and will try again.

I lloked at TB1 where some of the wires goes, says they should come from the PA, but then they don't exactly correspond to the points listed on the PA. Now just a more curious point, something I guess I just don't grasp, but all the wires going up to the PA are 18 guage or less wires, it would seem to me that with such high power output that it would have at least a few larger wires at least of the 12 guage or better. How do they accomplish this with such a small set of wires?

How >do they accomplish this with such a small set of wires? This is the kind of comment that worries the old farts. 20ga wire can carry an amp. 18 ga can carry at least three amps. The UHF Micor amp book (the only high power book I have handy) says that the final amp runs at 1,500 volts at up to 400 mils. That's 4/10 of an amp. 1/10 can kill you if it's applied right. 1500v can ruin your survivors entire day. Do I have to say it? WATCH OUT FOR THE HIGH VOLTAGE. If you don't have experience with it DON'T WORK ALONE. There's a reason they used to tell the old techs to keep one hand in their pocket - it prevented getting a lethal level of current from hot (one hand) to ground (the other hand) and incidentally through the chest. The heart muscle does it's thing with millivolts and milliamps. Matt, I don't mean to be insulting, or demeaning your skills, but this is YOUR LIFE we are talking about. If I were in your shoes when ever I was going to have my hands inside that beast with the power on I'd have a second person in the room, even if they were sitting in a chair across the room and studying a textbook. Or watching TV. Show them what switch to flip off (or better yet what power cord to unplug) before they drag your ass out of the cabinet and begin practicing their CPR skills. Mike WA6ILQ

RE: [Repeater-Builder] Re: TPN1132A Wireup help and questions
No it just buffers the COR no audio delay. The amp will work at 145 it will just not be as efficient. That should not be a big problem. Just stay within the limits of the tube. There are 2 different amps for the VHF micor the 250 watt used in the PURC and Micor and the 350 Watt used in early PURCs and all Micors. The only difference is a resistor on the screen I think. It's a big wire wound mother. The PA and most importantly the tubes will last forever if you remove the rear shield and relocate the low pass filter to the right side (from front) You will see the holes there already. Then mount 2 4" muffin fans on the 2 heat sinks. It takes them from to hot to touch to cool. We did this on about 50 paging transmitters back in the day after we added the fans we never replaced another tube and I was there for 3 more years. These transmitters were on P6 (158.7000) and were keyed for an average of 18 to 20 hours a day.

Mathew, Correct on the solid yellows and blues each one is an end and the one with a tracer is the CT. I think that the blue/yellow and the brown/green go to what would have been the rear door interlock. Did not make it to warehouse today (car troubles) I will take pictures and notes on a complete station I have at the shop. What cards do you have in card cage ?

There is two wires with c-clips on them, others call them another name, regardless the colors are: Blue/Yellow (about a 22g wire) Brown/Green These connectors are slip on type, I would think they attached inside the cabinet as I don't see anywhere on the system to plug them in, I'm thinking possibly safety switches. White White/Black Brown/White Black and Dark Grey together Solid grey Brown/Yellow These wires have ring terminals on them Red/Green Red/Yellow Red/White Two Grey Together White/Green Solid Grey There is a wire that has a small round push on type just behind the Remote Control, I'm thinking this must goto J5 on the metering panel, only an assumption. Going all the way down to the HV PS there is a group of wires from the harness. Red and Black 12 Guage wires, that follows up to the exciter, I am sure this is the 12v source for the transmitter. The other wires are: Brown/White Brown/Yellow Tan/Black Red/Yellow And last but not least, wires from the HV going to the LV, which I do believe will connect to TB1 on the LV and if correct should be as follows: TB1-3 = Blue TB1-1 = Blue/Yellow TB1-2 = Blue TB1-7 = Yellow TB1-5 = Yellow/Green TB1-6 = Yellow Thanks for the help Mathew Going to make another assumption here, there should be no difference in both solid blues or solid yellows, and that they should be reversable between either TP1 points? And the AC input power goes to TB1 on the HV power supply --- In Repeater-Builder@yahoogroups.com, "KD4PBC" <[EMAIL PROTECTED]> wrote: > > No problem Mathew just don't want to lose what few Hams we got left. > > I will look at a station today and let you know where the wires go. > How are you on the harness ? > > Robert > Yahoo!

RE: [Repeater-Builder] Re: TPN1132A Wireup help and questions
No problem Mathew just don't want to lose what few Hams we got left. I will look at a station today and let you know where the wires go. How are you on the harness ? Robert
RE: [Repeater-Builder] Re: TPN1132A Wireup help and questions
Mathew, Just looked you up on QRZ.com. Nice Shack looks like you may have some HV experience. Still be careful !

I'm sorry but I feel that I must chime in on this project. First you wanted to find out how to hook up and power supply on a repeater that you know nothing about Except that that it has a 330 watt amp. Now you think that you know how to hook up the power on a still unidentified repeater that has now a "KW" amp. That said. Sounds like you have a Motorola Micor. Look at anything that has a frequency exciter, PA receiver... If the part number is like TLB-3130 then the "B" leans low band 27 -50MHz if the "B" was a "C" then that would be Mid band 72-75 MHz (never seen High power but there is always SP) if it was "D" then VHF High band 150-170 MHz If it was "E" UHF somewhere from 406-512 MHz and finally if it was "F" then 806-960 MHz . Now that you may have a better understanding of what you are dealing with but should have been able to figure out with the manual. Let me say that you have no business working on this monster yourself. This may be all new to you and Ham radio is all about learning . But you have to live through it to learn. There are several points in the Micors that can kill you starting with the line voltage. Micors are old I know this because I worked on one of the 1st ones that was made in 68 I think. Because of that there are a lot of us old guys out there that are willing to help. Find one of us. We will help, we will make sure that you don't kill yourself, we will teach you. If you can't find one of us to come over and help have a friend come over and just keep an eye on you. Tell him what to unplug and who to call if something does happen. Then have fun. The low voltage power supply goes under the hi voltage supply in the rack. There are some yellow and blue wires that connect the low voltage side of the transformer on the hi voltage supply To the rectifiers, filters and, regulators for the IPA 12Volt, the Audio 12 Volt and the 9.6 Volt for the channel element. The harness should be in one piece and just plug into various places. If the harness has been cut then I may be able to get you one depending on the band. There are some mods to the PA that will make the tubes last forever we will get to those. You most likely will not need to do anything to the PA depending on where you are in the Ham band 145 MHz I'm unsure I have been down to 146.940. Again pending final outcome of what it is you have. Mathew SAFETY FIRST. There is a lot of knowledge on this board but not even the smartest person can save you life via email.

This is the VHF Motorola Micor Upright RT system with the KW amplifier. Although I am told that the amp will have to be converted to make it down to 145.410. The rest of the repeater has already been converted. I will give a list of all the TLN parts tomorrow. I do have the service manual on the system. I know there are several switches that must be closed in order for the system to function, and that there is a wire harness that has several connectors on it that I am not sure where they go. I want to get the repeater up and functional, then I will go about tuning it to our frequency. I'm working diligently to get this up and running hence our repeater was struck by lightning last month and destroyed.
