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. |

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 1,600 files listed here, occupying over 1.8 gigabytes 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 which 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.
If so, please check out our "Wish List" page... Everything listed there 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 WA6ILQ at (callsign) /at/ repeater-builder /dot/ com with a subject line referencing the "LBI Wish List". Note that all I can do is add your request to the wish list... I can't answer very many GE technical questions - as my personal library and radio experience is 99% Motorola... |
This web page, by itself, if printed, would be over 96 pages long - and it's just the index. You can download a local copy of any 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 a copy of Adobe's Acrobat file reader, available here.
Depending on who scanned the files, some are not as good a scan / as clear a scan as others. Sorry, but that's the way it is - we post what we are sent. The best results come from folks that loans us an actual paper LBI in good condition. There 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 then you can have a local graphics shop print the wide pages - put the file on a a floppy or a USB thumb drive (or you can email them the file) and tell them to print specific page numbers.
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. will have a "title page" or "cover page" or "a table of contents" LBI (for example, look at LBI-30055). 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 any option like dual front end, etc. And so on.
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 reciver, another one for the control head, speaker and mobile microphone, plus LBIs for any option(s) such as channel guard, channel scan, siren/PA option, etc.
To create a manual, start with the appropriate Product Code Index, (for example PC67) and your Combination Number. That will give you the master LBI number. From that you can extract the component LBIs. Any of those may be a cover page listing other LBIs. To have a complete manual you will need to collect all of those LBIs as well. Hence a 3-ring binder. And if any of hte LBIs are noted as "Full Page" you will want to copy them to a thumb drive and take them to a print place that has a roll feed printer (any big copy shop or any graphics shop).
Unfortunately, not all the LBIs you need may be here (thats where folks that are willing to loan their paper LBIs to us to scan can now step up to the plate).
Any missing LBIs that we know of are on our "Wish List" page, if you stumble across another one please drop a note to Mike WA6ILQ at (callsign) at repeater-builder dot com.
This is a work in progress. 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 Mike WA6ILQ at (callsign) at repeater-builder dot com 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. For one thing, there is a different email address to send the donated files to. Or if you would prefer to use anonymous FTP there is a drop box that was set up for this on a FTP server with a free space quota of over a gigabyte.
If you are looking for an Ericsson-numbered document then this writeup may help... their numbering scheme is very different: T1905R1B - Ericsson Document Numbering System.
Before you pick up a soldering iron, I suggest that you read LBI38737 - the GE writeup on Electrostatic Discharge Protection (ESD).
Searching the index:
This web page can also be used to look up LBI's, 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 / 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. 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 LBI30027 - it replaced LBI4561, and later on LBI30027 itself was replaced by LBI38504). Or maybe it needs to be added to our "Wish List" page. If it does, send WA6ILQ an email.
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 one... 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... i.e. if you are looking for LBI-30102M you will want to 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 / strip numbers. When you do a board search or a strip number I suggest that you leave off any alpha-numeric prefix and suffix and any dashes... this way 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 would want to drop any and all dashes, the leading numberic (the 4) and the trailing letter-numeric suffix (the A10) and type in just the ET88. If you don't find it try "ET-88" but I think I caught all of those as I created (and updated) this page. Yes, even if the radio nameplate says "KT-77-C" you will want to search for "KT77C".
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 are in ALL CAPS, 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 web page.
Some of the LBIs presented here were produced within GE / Ericsson / Tyco, others were scanned piecemeal where the foldouts ended up as multiple individual scanned pages, and 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 LBI3502.
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 and frees up the channel.
CG: Channel Guard - GEs version of CTCSS / PL
CB: Channel Busy - GEs name for a signal that is true when the channel is in use - think "COR". 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.
DODT: Drop out delay timer
EDACS: Enhanced Digital Access Communications System
NLA: No Longer Available
PLL: Phase Locked Loop
PSLM: Priority Search Lock Monitor
RUS: Receiver Unsquelched - A signal that is true when the receiver is unmuted. If the receiver is in CG mode then the incoming signal has the right CG tone.
SAS Board: System-Audio & 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 1.8 gigs 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 it's commercial grade hosting, with commercial grade bandwidth (and we're using over 40gb of bandwidth a month, getting over 600,000 hits and serving up over 150,000 pages). If you find this web page and web site useful please consider a donation towards the continuation of it:

The fine print:
Note that all of these PDFs are © Copyright General Electric and it's
successors (such as Ericsson and currently Tyco). The copyrights are
still current, and get renewed as needed. These files have been made
available for non-profit individual use. Specifically,
and in words of three syllables or less, you may not download this
collection, burn CDs or DVDs of all or part of over 1700 files (and counting)
totalling over 1.8 gig (and still growing) of info, and sell it on eBay or
anywhere else. And the non-profit individual-use limitation of
these LBIs means that they may NOT be used to enhance anybodys eBay
auction! 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 500 hours of donated time over the last two years this GE data compilation so far, and it's not done yet (we at repeater-builder really want to make it data base driven rather than just a plain hand-edited static html page... any web gurus out there?). 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 100 LBIs scanned professionally by a graphics shop that had a wide-format scanner. 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.

This bulletin describes the construction of a filter, useful for supressing spurious radiation at one specific frequency...." |
| Datafile Bulletin 10002-2 | 1,859,919 | Radio Frequency Interference (RFI) in Two-Way FM Radio Systems "The major types of radio frequency interference (RFI) which are apt to be encountered in two-way FM radio systems are described in this bulletin. Special emphasis is placed on the role of receiver selectivity in preventing interference. Since technicians normally notice and identify RFI by its degrading effects on receiver performance the effect of each type of interference on the receiver is discussed in detail. A practical procedure for (1) analyzing and solving RFI problems in existing radio systems or (2) predicting problems in proposed systems is presented, based on the use of the Interference Analysis Work Sheet (Bulleting 10002-3)." |
| Datafile Bulletin 10002-3 | 199,688 | This is the Interference Analysis Worksheet that must be used with Datafile Bulletin 10002-2.

This Bulletin describes how duplex operation curves are prepared and how they can be used to calculate the amoutn of attenuation required between the transmitter and receiver (using Datafile Form 10007-5). It also describes how to find the amount of antenna spacing and/or the type of filters required to obtain this attenuation."

(see LBI-4323 for the 4EP38A12). Other search hits: 4EP-38, 4EP38, EP-38 Safety/Equipment Note: The EP38 series has a semi-fatal design flaw: The transmitter high voltage bleeders are carbon resistors, are undersized and poorly ventillated. The trapped heat chars and burns a hole in the circuit board over time (many years). Also the resistors sooner or later age, crack and the exposed carbon can catch fire from the heat. The flames then completely destroy the circuit board (no longer available as a spare part). If you have one of these supplies in service I suggest that you immediately (like this coming weekend) replace the resistors with a higher wattage ceramic (i.e. flameproof) replacement and stand them off the board an inch or so for convection cooling. Note that the resistor leads carry high voltage and you will want to use teflon sleeving over them. A second, less critical flaw is that the two PTT relays wear out and they are NLA. I've replaced them with a pair of octal plug in KRP series relays. Simply remove the old relays and mount a piece of sheet metal over the holes and punch two octal socket size holes in the new metal then mount and wire the sockets of the new relays to match. Plug in two new relays and the supply is good for another 10-15 years, and at that time (if it's still in service) new relays can be plugged in. |
