[Repeater-Builder] Tuning Microwave Solutions duplexer
I have an uhf Microwave Solutions duplexer, at the moment it is a spare unit but sooner or later I hope to use it. It is not built like the more common duplexers with have several cavities in series and each one has one plunger, this one has only two cavities, one for the high and one for the low side with I think each 7 resonators inside, the fed one, the antenna one and 5 in between, and they don't seem to be connected with cables or the like. Each one can be tuned and there's always an additional tuning screw in between the resonators. I wonder how to go about to tune this one? Regards Martin

Tis a finger burn to remember for a long time can be helped immediately by
putting the boo boo finger (no, not there) but along the area of the nose, ear,
the places that excrete your own human oils placed on the burn.. Ever grab
a soldering iron on the wrong end? Whew does that hurt. The personal oils
of your skin are a natural and rapid reliever and healer of the pain.
Learned that from an old Ma Bell stepper switch guy.

[Repeater-Builder] Microfiche scanning?
I have what I believe to be a complete set of GE two-way manuals on microfiche. The main library is dated 1980/1981, and there are update packages that go up through the mid 1980's. Most likely the base library includes radios dating back much older. I don't have a microfiche reader (nor do I really want one). I thought I'd check here to see if anyone has access to a microfiche scanner who might want to take on a project for good of the repeater-builder community. Or, if there are no takers, I'll consider donating the library to someone who does have a microfiche reader that could make good use of them and share the information with others. The GE LBI CD's probably have many of these manuals, but not all of them, nor all of the revisions that occurred over the years. --- Jeff WN3A

RE: [Repeater-Builder] Microfiche scanning?
Jeff, I, too, have the complete GE microfiche file, along with a microfiche/microfilm reader. I already had the reader, because I do a lot of genealogy research, and the census records are published on microfilm rolls. The GE microfiche file is on indefinite loan from a former GE land-mobile radio dealer who appreciates its value to the Ham community. Up until a year or so ago, I was able to use a reader-printer at a nearby military technical library, but the machine died and was never replaced. Even if a microfiche printer is working perfectly, the quality of images produced is far below that found in an original document, and that is why I always want an original printed paper copy to scan. The resolution on a GE microfiche is adequate for viewing, but is poor for creating a new hard copy. Also, the images are no larger than an 11 by 17 inch scan, which means that many schematics are chopped up into pieces. It is an extremely tedious process to print images from a microfiche, and takes perhaps a half-hour to print a 20-page document. Due to the somewhat random alignment of the images on the fiche card, every page must be manually aligned so that it prints correctly. The GE microfiche file is an important resource, but it is difficult to transfer back into hard copy. I use my file primarily to identify GE module or equipment numbers, and to convert between combination numbers and package numbers. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Jeff DePolo Sent: Saturday, May 24, 2008 9:41 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Microfiche scanning?

RE: [Repeater-Builder] Dayton 2008 Chuckle (Tac-Tec - humor)
A lot of people made me feel bad when I told them I wanted $300.00 for my 75 watt Mastr II repeater station (not a mobile) complete with Wacom duplexer and multi-CTCSS tone panel! Heck, I could not sell a working RCA 700 desktop repeater ready to go on 444.975 for 50 bucks! I don't know what these people wanted. I think most wanted me to give them the equipment and pay them to haul it off. A foreign type guy wanted to buy a test cable for $5.00, I said no, that would be like giving it away. He then offered to buy two for 15, said no again. I did come down a lot on some things but for the most part I held firm like on the repeaters.A guy told me he bought a Micor complete with a duplexer for 100 bucks, I am sure he did. I have been given a lot of equipment like that but it does not mean I am going to give it away when I haul it that far. I would rather bring it back home and I did. The funny thing, I sold the GE Mastr II to a fellow club member here in Texas so I had to bring it back anyway!

I too have 1-2 complete sets as of the last factory updates and 2 that digress backwards with pulls from prior updates. A lot that is in it was never in CDROM.. Much I never even saw in Paper. When the Cleveland GE office closed I ended up in possession of theirs so I have what is probably 2 pretty complete setsI just cannot throw them out either... We still have a lot of the paper datafiles that predated the microfichein storage... Cant bring myself to trash them either:-) Our local County Library organization keeps microfiche printers for re-printing old newspapers etc so for the time being I still have a tool to make them paper...as needed... and we still do have our optical reader too..

I did come down a lot on some things but for the most part I held firm like on the repeaters.A guy told me he bought a Micor complete with a duplexer for 100 bucks, I am sure he did. I have been given a lot of equipment like that but it does not mean I am going to give it away when I haul it that far. I would rather bring it back home and I did. The funny thing, I sold the GE Mastr II to a fellow club member here in Texas so I had to bring it back anyway! I still have a lot of GE and Motorola UHF base stations for sale, guess I will try Belton, Texas in the fall if fuel is not 10 bucks a gallon!

Re: [Repeater-Builder] Dayton 2008 Chuckle (Tac-Tec - humor)
I had heard about the TAC200 that the problem was inferior quality control on the incoming parts and the failure rate on some capacitors was terrible. I had experienced that particular problem. They were similiar to the Mastr II but the board layout was reversed left to right and so on. Worked on quite a few of them in their day.

That radio single handed put RCA out of business.

[Repeater-Builder] NOS and old vacuum tubes
Sort of... also depends a lot of the type of tube. The problem is air getting past the base pins where the glass and metal meet is never a long term 100% seal. http://en.wikipedia.org/wiki/Vacuum_tube cheers, s. Don't tubes age just sitting on a shelf? I still have a bunch of brand new tubes for Mastr Pro Stuff.

RE: Old tubes (was Re: [Repeater-Builder] Re: mice and the trusty old GE Master Pro)
They don't age by sitting on the shelf. They work just fine after sitting there. One of my other hobbies is Hammond Organs and I have plenty of vintage tubes that are still going strong. Doesn't matter if you use them and then leave them sit for a while either. Now capacitors that is a whole different ball game.

[Repeater-Builder] Re: Need help IDing Celwave filter
Thanks for all the replies on the Celwave filter, including Jeff's info. I picked up a few of these a couple of years ago at Dayton ( the guy in the middle of the fleamarket every year that has all those nice jumper cable assemblies), and at the time quickly installed one in front of a GM300 link radio at another site. My link receiver was getting hammered all day long from the 20 or so UHF systems at the site mixing with each other, and the filter worked like a champ. The receiver has been interference-free ever since. At the time it was a fast and sloppy tune, but it has been working ever since. Not too critical for a link receiver application, but this time around it is going on an MSR2000 repeater receiver, so every db counts! I was able to tune it quite nicely to pass a window of 440-450MHz (give or take) with two nice notches in the 460 and 470 areas, so it should take care of a minor issue I have at one of my sites. Just under 2db insertion loss including two 24 inch sma to n RG400 jumper cables. About 30-40db down above 460MHz, and two nice 50+db notches. I should have picked up a few more of these as cheap as they were. Although, I did waste a few $$ on some larger filters he had with N connectors. Those would not reach above 430MHz, so I eBayed them and they went to a Eurpoean ham club. I also wish I would have picked up some of the nice sma-bnc or N cables that he was selling this year. The time I spent making them up, not including materials, was worth more that he was selling them for.. 73 Eric KE2D www.w2njr.org --- In Repeater-Builder@yahoogroups.com, [EMAIL PROTECTED] wrote: At 5/22/2008 19:13, you wrote: Eric, The 9182510Y17 filter is a Motorola product, made by Celwave. Call Motorola Parts ID at 800-422-4210, and have the clerk find what the Celwave part number is. Then call Celwave (RFS World) to get servicing data. It may be a long shot, but also ask the Parts ID clerk what Motorola manual covers this filter. You might luck out- if it's not out of print. It may be a good idea to ship the unit back to Celwave for a factory conversion to your desired frequency. Such units seldom can be moved more than 10 or 15 MHz without loop adjustment. I have 3 of these window filters, though not quite the same part # (9182510Y26 9182510Y01 and 'Y02). The Y26 filter tuned into the 440 band with no problems (as received it was tuned to 409-416 MHz), while the Y01 needed modification to bring it up into the ham band. I can't remember the details of what I did other than I lengthened the threaded rods by soldering some heavy-gauge solid wire to the ends, removed a wire coupler that was placed between 2 of the sections. One of the Y01s/Y02s is on the mountain, so I can't pop it open but I may have another one kicking around at work. If I do you need the mod. details let me know. The center passband loss should be around 1 dB. Bob NO6B
