GE LBIs available at www.repeater-builder.com The 'MASTR' Index of GE LBIs Hosted at www.repeater-builder.com Compiled by Mike Morris WA6ILQ Maintained by (No, LBI does not stand for 'little bits of information'). An LBI is a GE radio technical manual section. The term comes from the phrase 'Lynchburg Book (of) Instructions.' Lynchburg, Virginia has been the home of GE's land mobile radio division since 1958. The original prefix (up to about 1947) was GEI, for General Electric Instructions. At that time they became EBI for Electronics (Park) Book of Instructions until 1958, which is when the plant moved to Lynchburg.

DO NOT use the information provided herein to promote your eBay Auction (click, then email the site owner, see the bottom of this page.) Please read this introductory section (at least once.) Among other things, it tells you how to search the index. This web page is an index of the available LBI files here at www.repeater-builder.com. There are over 1,700 files listed here, occupying almost 2 GB of server space just by themselves.

This collection was assembled by merging the personal collections of a number of fine folks plus individual donations from others, none of whom cared about public recognition. Despite that, here's a public 'Thank You' - you know who you are. This is one of the very few pages on this web site where individual donors are not listed - this is because over 70% of the LBIs were donated by folks that wanted to stay anonymous. Do you have a file cabinet full of LBIs? If so, please check out. Everything listed on the wish-list page is something that someone has asked for, or we have noticed is missing from the LBI master list.

If you have one of those, please loan it to us. I will put you in touch with a volunteer with a top quality scanner (look at any page noted as 'Full Page' for the quality of work that he does) who will scan your LBI and return it, and the resulting PDF file will be added to this page. And if you would like us to have us add something to the wish list page just drop a note to with a subject line referencing the 'LBI Wish List'. Note that all I can do is add your request to the wish list.

This web page, by itself, if printed, would be over 100 pages - and it's just the index. You can download a local copy of any LBI file onto your machine by just right clicking on the file link and select 'Save As'.

To view and/or print these files you will need. Depending on who scanned the files, some are not as good or clear as others. Sorry, but that's the way it is - all we can post is what we are given. The best results come from folks that loans us an actual paper LBI in good condition. In that situation we can use the top quality full-page scanner that has been made available to us, and produce the best image, as well as scan each schematic pull-out sheet as a single ultra-wide page. In contrast, folks that have a standard narrow single page scanner have to scan the wide pages in multiple scans that you will have to individully print and tape together (or use 'stitching' software to merge the individual scans into one wide scan).

If you have problems printing one of the ultra-wide pages please see the comments in the paragraph below (the one titled 'You can create.' ) Note that there is no one single manual for any GE radio. The complete 'manual' for any specific station (base or repeater), be it a MASTR II, a MASTR Exec, a MASTR Pro, etc. Is a stack of LBIs and will have a 'title page' or 'cover page' or 'a table of contents' LBI as the first page (for example, look at LBI-30055). Torrent Html5 Builder. That cover page LBI will list a half-dozen (or more) additional different LBIs, depending on functionality and features - which is why many 'manuals' took the form of three-ring binders - complete with a configuration page in the front (listing the positions of the various option jumpers) and a maintenance log in the back.

There will be one LBI for the transmitter exciter, another one for the transmitter power amplifier, another one for the control board (or control shelf if it's a station), another one (or two) for the RF and IF sections of the receiver, another one for the audio squelch board, another one for the Channel Guard™ board, another one for the mobile control head, plus one for each option like dual front end, etc. Even the mobile manuals started with a title page LBI covering a collection of LBIs (again, sometimes in a 3-ring binder). There were separate LBIs for the exciter, the power amplifier, maybe three or more LBIs for the receiver, another one for the control head, speaker and mobile microphone, plus LBIs for any option(s) such as Channel Guard, channel scan, siren/PA, etc. You can create your own custom manual for your radio - just start with your product line name (i.e. MASTR II) and your Combination Number (from your radio nameplate). Then go to the appropriate, (for example PC67) and look up the Combination number. That will give you the master LBI number for your radio (the top-level table of contents).

Look that LBI up and print it. That gives you a 'shopping list' of component LBIs. Go print each one of those. In most cases they will not reference any more LBIs, but if they do, add those LBIs to your shopping list. If any of the LBIs are noted as 'Full Page' you will want to copy them to a floppy or on a USB flash drive (also known as a thumb drive or pen drive), and take them to a printing place that has a roll feed printer (any big copy shop or any graphics shop). Just call around and ask if they can print PDFs from a USB flash drive to a roll feed printer.

Some places will let you email them the file. Once they have the file you can tell them to print specific page numbers. 'Kinko's' is one well known copy shop chain that has roll feed printers at about 1/3 of their stores (i.e. One in every major area). They started on the west coast and are now nation wide.

(Update: Kinko's was purchased by FedEx in 2004 and as regular maintenance replaces building signage they are slowly dropping the Kinko's name and the newest signs I've seen have the name 'FedEx Office'.) Unfortunately, not all the LBIs you need may be here (that's where folks that are willing to loan their paper LBIs to us for scanning can now step up to the plate). Sometimes you can work around a gap - if the carrier squelch audio board isn't in our library, and the CG one is, then you will have to make do with the CG one until you can locate the one you need. Any missing LBIs that we know of are on, if you stumble across another one please drop a note to and let us know.

When you do, please let us know the LBI number and what it is for - something like 'LBI-30766 for the Porta-Mobil II audio-squelch board'. This is a work in progress that started in early 2004. We know that this collection has some gaping holes. If you have any LBI files that we don't, or if you have an LBI file that is better that the one we have (clearer scan, newer version, or perhaps more complete, etc.) or have any other comments or additional info please send an email to with a subject line referencing this page. Something like 'LBI page info', 'new LBI file donation', 'replacement LBI file donation' or something like that.

DO NOT just blindly send the LBI files - please drop a note first. Or you can drop a CD in the snail mail. If you are looking for an Ericsson-numbered document then this writeup may help.

Their numbering scheme is very different:. Before you pick up a soldering iron, I suggest that you read. Searching the index: This web page can also be used to look up LBIs, individual board numbers (such as 19A, 19B, 19C, 19D, 19E or 19J items) or the GE Datafile Folders. Just use the text search feature built into your browser by hitting Ctrl-F and typing in the text you are looking for - 'MASTR II', 'MVS', etc. As I built this page I had to open up and look at each LBI and I tried to grab the relevant numbers. Comments and corrections are welcome if you stumble across something that should be in the descriptive text, or if I missed something.

When you search I suggest that you search this entire page, don't just stop with the first hit - go all the way to the end. There maybe more than one mention of a board and you may want to look at each one - the same receiver IF board, for example, could have been used in a number of different radios, and the first one you find may not be the exact version of the board you have in your hand. Or another hit further down in the list may be a later LBI version, and have an update notice embedded in it. Or there may be a later LBI that replaces the one you are looking for, or a newer revision (example: scroll down to LBI-30027 - it replaced LBI-4561, and later on LBI-30027 itself was replaced by LBI-38504).

Or maybe it needs to be added to. If it does, send an email to. If the term or phrase you are searching for could have been abbreviated, or spelled in several different ways, you will need to try all the forms or combinations - I think I caught all of those as I created (and updated) this page but I may have missed some.

For example, if you are looking for a MASTR II PLL exciter, try looking for 'PLL' and then do a second search for 'phase locked'. Then a third for 'phase-locked'. To find a specific LBI just scroll down to it, or search for it: leave off the 'LBI' and the dash and search for the number itself, without the trailing letter revision identifier. If you are looking for LBI-30102M you should search for '30102'. To find a DataFile Folder just type in the number, i.e.

For DF-1107 just type in 1107. Again, please search all the way to the end of the list in case of the same data file appearing with different LBI files - the older versus newer revisions situation. Yes, you will also catch any LBIs that have a 1107 in the number, but until this web page is converted into one that is data-base driven that's all we can do. The above technique works on everything but circuit board numbers and assembly or strip numbers.

When you do a board search or a strip number I suggest that you leave off any alpha-numeric prefix and suffix but include the hyphens; you will have a much better chance of finding what you are looking for. In other words, if you are looking for a 19D123456G3 or PL-19D123456G-3 just type in 123456.

If you are looking for 19B987654P21 just type in 987654. This is because of the multiple different board variations and how GE listed them. Some LBI entries list the suffixes individually like '19D123456G1, G2, G3, G4, G9', others use an ampersand like 'G1 & G2', others use 'and' (like in '19D123456G1 and G2'), others use a dash like 'G1-G4', and others mix it up like 'G1 & G3, G5, G6, G9-G17 and G21', So if you are searching for 19D417075G12 you will never find it if the LBI has 19D417075G9-G16 in it. You have to search for 417075 to find it. On strip numbers like a 4ET88A10, 4-ET88A10 or 4ET-88-A10 you should first try searching for 'ET-88' then try it with the leading number (the 4) then with the trailing letter-numeric suffix (the A10). If the radio nameplate says 'KT77C' you will want to search for 'KT-77-C', in other words, WITH hyphens.

As said above, this collection was generated by merging the collections of several different folks. Due to this fact the descriptions are inconsistent - some are detailed with board numbers and cross-referenced LBI and Data File numbers, some are very sparse, some were in ALL CAPS (which have finally been fixed), and a good chunk of each collection was blank (the total blank started out at over 70%), requiring opening each and every PDF and hand typing the description into this index page. Some of the LBIs presented here were produced within GE / Ericsson / Tyco, others were scanned piecemeal by individuals with limited personally owned equipment - on these the foldouts ended up as multiple individual scanned pages. Yet others were scanned with a wide-format scanner which produced the foldout sheets as one wiiiddddeee scan. These last ones are noted as 'Full Page', for example see LBI-3502. We've had a few coments about the full width scans, but we where we had access to the wide scanner we chose to scan the long foldout pages directly into PDF as one file, so that the end user does not have to tape together pieces of a large schematic that were scanned in many narrow segments. The free Adobe Reader program has a neat feature known as the 'Snapshot Tool' in the Tools menu.

The user can select a small portion of a large schematic with this tool, and then print it on standard 8.5 by 11 inch paper. Useful Definitions: • AKA: Also Known As. • CCT: Carrier Control Timer, i.e. PTT time-out timer. When the driver sits on his microphone this timer saves the mobile transmitter from meltdown and also frees up the channel.

• CG: Channel Guard - GE's version of CTCSS / PL / QT / etc. • CB: Channel Busy - GE's name for a signal that is true when the channel is in use. This is different than RUS as that signal takes into account the position of the CG On / Off switch and the presence of any CG tone. • DOD: Drop Out Delay (the time that the repeater transmitter carrier stays up after the RUS drops out).

Some people call it a carrier delay timer, or a hang in timer. • DODT: Drop Out Delay Timer (the actual timer circuitry that implements the DOD).

• EDACS: Enhanced Digital Access Communications System. • EDACS-L: Every Day Another Customer Screams Louder. • NLA: No Longer Available. • PLL: Phase Locked Loop. • PM: Percussive Maintenance (i.e. Forcible application of a blunt object).

• PSLM: Priority Search Lock Monitor. • RUS: Receiver Un-Squelched - A signal that is true when the receiver is unmuted.

If the receiver is in CG mode then the incoming signal has the correct CG tone. • SAS board: System Audio and Squelch board. • SOR: Squelch Operated Relay.

• TOR: Tone Operated Relay. • UHS: Ultra High Sensitivity - an optional receiver preamp. (More to come.

Suggestions welcome!) Three final notes: 1) The GE authors had a very bad habit of not stating what product line a module was made for: LBI-38673 is a good example; I had to figure out it was a MASTR III. On the ones where I was able to crack the code you will find the product line mentioned in the description text (for easy searches). Comments and updates from folks more familiar with the equipment are welcome. 2) You will notice that this list contains multiple versions of the same LBI. No, we're not padding the list with more files to make the list look bigger. The reason is that we have found that sometimes the older versions are more complete, and need to be kept available. We just don't have the time to check line by line, page by page, file by file, as to which version is more useful (which in most cases requires some detailed familiarity with the particular equipment), and as cheap as disk space is today, we just decided to make everything we have available.

3) Speaking of disk space, as said above this one web page alone indexes over 1,700 files that occupy almost 2 GB of server file space. This web site is hosted at a commercial hosting company, and Kevin Custer W3KKC pays for that out of his personal funds for its commercial grade hosting, with commercial grade bandwidth (and as of mid-2010 we're using over 45 GB of bandwidth a month, getting over 650,000 hits and serving up over 175,000 pages).

Them's the rules, and if we are to have access to this resource we have to play by them.

Mike Morris WA6ILQ alone has over 750 hours of personally donated time over the last several years on this GE data compilation so far, and it's not done yet. He hasn't dared to ask how many hours other folks have put into collecting, scanning and making PDF files for this collection - a lot of it came from paper files and was scanned page by individual page. And at least one of the folks donating paid out of his own pocket to have over 150 LBIs scanned professionally by a graphics shop that had a wide-format scanner (if you see a 'Full width' noted LBI, that's one of them). All in all, it would be a shame to have to take this LBI collection off-line permanently because one or two idiots screwed the deal.
