The Motorola MSF5000 and PURC5000 Station Index Page Formerly Maintained by Robert Meister WA1MIK (Who knew a hundred times more about the MSF than the current page maintainer) Currently Maintained by Mike Morris WA6ILQ I know very little about this equipment! You can ask, I'll answer if I can... It's probably best to ask on the repeater-builder mailing list. Some of the product like literature includes a space in the product names (MSF 5000, PURC 5000), and some other pieces of literature do not. For consistency we've removed the space on this web page and most of the accompanying articles.

CONTRIBUTIONS TO THIS PAGE ARE WELCOME!
Actually to any page at this web site!

One of the things we are looking for is the schematic of the Motorola CDN6351A cable (possibly CDN6321A) to connect external equipment to a paging or repeating station like the MTR2000, PURC5000 or MSF5000. That cable was originally designed by Zetron as their part number 950-9919 and has an integrated summing amplifier that mixes multiple sources (like a paging encoder and a local microphone) into a single output. At one point it was priced at over US$300. If anyone has one sitting on a shelf we'd like to borrow the included paperwork for scanning for this web page.

Note that the MSF5000 was the USA repeater / base station and the MSF10000 was the export version. The PURC5000 was an MSF-based paging station that replaced the MICOR-based PURC paging station and you should look on the MICOR pages at this web site for information on it.

Background and Introductory Information:

You should read the first few articles below before anything else here in the MSF/PURC section.

	MSF/PURC Introductory Information   by Mike Morris WA6ILQ An introduction to the MSF and PURC stations, with background, some history, some model-specific information, photos, and other miscellaneous information.
	An original MSF5000 Sales Brochure, dated 1983. Donated by Robert W. Meister WA1MIK,   2.5 MB PDF file. We don't know if this was the introductory brochure or a later one. Either way, it's still and interesting and educational reading.
	A Photo Tour of the MSF5000 Stations   By Robert W. Meister WA1MIK This article began with a UHF station but now includes some information about the VHF and 900 MHz stations. It also describes the two MSF metering panels and the TRN7794A tuning tool kit.
	MSF5000 Beginner's Guide   By Robert W. Meister WA1MIK A guide to things you need to know about these stations, especially if you get put in charge of one that your local repeater group has just acquired and don't even know how to spell MSF5000. It should answer a lot of first-timer's questions.
	The VHF Battery-Charging Power Supply Wiring   By Robert W. Meister WA1MIK This article is necessary reading for anyone that has a 28 volt station! It tries to shed some light on the situation, resolve the confusion and correct the omissions in the Motorola manuals. The VHF station power supply generates 14 volts DC as well as 28 volts for the 25 watt and higher PAs. The 28 volt battery-charging supply connects to two 12 volts batteries in series and the necessary wiring is not at all obvious, nor is it clearly documented.
	MSF5000 Power Supplies   By Robert W. Meister WA1MIK A summary of the various power supplies, along with links to all of the available power supply manuals and pieces thereof that have been posted here. Also contains some useful theory and troubleshooting information, although the older manuals have much more to offer.
	MSF5000 Metering   By Robert W. Meister WA1MIK An explanation of what each metering jack position measures, along with typical meter readings.
	Investigating the MSF5000 Squelch circuits   By Robert W. Meister WA1MIK An investigation of the two squelch circuits in the station. This finally answers the questions about how they're different and which one to use.

Interfacing and Control Articles:

	Please note that interfacing techniques are pretty-much band independent and while one author may have interfaced a brand X controller to a VHF unit his methods will work on a UHF unit also. Just remember that some MSFs are powered by 24 volts and others are powered by 12 volts...
	Most of the audio circuitry inside the MSF5000 Control Tray is DC-coupled, is powered by +9.6 volts DC, and is biased at 1/2 VCC (i.e. at +4.8 volts DC). If you will be connecting anything directly to the TX or RX Audio stages on the control board, you need to add a 10µF 16 volt electrolytic capacitor in series with your audio signals with the positive side towards the control board. Many of the unused signals are connected to this +4.8 volt bias using push-on jumpers. If you remove a jumper you may have to also bias the signal to another source of bias voltage through a 10 k ohm or higher value resistor.
	You should verify that the 3-pin 2-way jumpers on the SSCB and TTRC are set to their default positions before doing any interfacing. The articles below make no mention of these jumpers unless they have to be changed. The default position is indicated by a white silk-screened bracket over or near the jumper. The TTRC schematic shows jumpers with "A" and "B" positions; "A" is the normal or default position; "B" is the alternate position.
	Interfacing the Masters Communications RA-42 to an MSF5000   By Steve Arntz KM5HT Everything you need to know about connecting the RA-42 USB AllStar radio adapter interface to an MSF.
	MSF5000 Interface Signals   By Robert W. Meister WA1MIK Everything you wanted to know about the available signals an external controller could use, but didn't know whom to ask...
	Interfacing the MSF5000 to a CAT 200 or CAT 250 Repeater Controller   By Robert W. Meister WA1MIK Yet another method of connecting an external controller to a digital station.
	Interfacing an Analog MSF5000 Station to a Repeater Controller   By Jim Reese WD5IYT; 240 kB PDF file. While Jim is interfacing an analog station to a home-brew controller the basic concept is useful - as long as you have the right voltages COR is COR no matter if it's a home-brew controller or an NHRC, a Link / RLC or an S-Com, etc.
	Interfacing an Analog MSF5000 Station to an RLC Repeater Controller   By Author Unknown; 75 kB PDF file. Another user's interfacing information, oriented towards the analog MSF5000 and the RLC repeater controllers.
	MRTI Interface Cable Documentation   By Robert W. Meister WA1MIK This article describes how a real MRTI interface cable connects to the MSF5000 station. Pin numbers, wire colors, and signal names for both ends. Not documented elsewhere.
	ACC RC-850 Interfacing to an MSF5000 station   160 kB PDF from an unknown source. While oriented towards connecting an ACC RC-850 to a CXB series MSF5000, there is good information on connecting to any controller.
	ACC RC-850 Interfacing to an MSF5000 station   Transcribed by WA1MIK. A somewhat updated and corrected HTML version of the above article, although there is still a lot of information missing, like all the RSS settings for the MSF5000 and the configuration for the RC-850. While initially done for a VHF station, the information is suitable for any MSF5000 analog-plus or digital-capable station.
	MSF5000 Analog Repeater Interfacing   By Paul Blum K9ARF Information on many of the available input and output signals, including a rather unique way to access some of the hidden PTT signals from your repeater controller. This same idea can be used to access other MUXBus signals as well.
	MSF5000 Standardized Repeater Interfacing   By Matt Lechliter W6KGB Yet another method of developing a standardized interface, for both analog and digital stations.
	Interfacing external repeater controllers to the analog MSF5000 repeater   By David Rudd AI4JI A simple method of connecting an external controller to an analog station. This article was here, then removed after the web site went away. It's back becasue a copy (dated January 2020) was found at the Wayback Machine.
	Interfacing an S-Com 7330 to an MSF5000 digital-capable station   By Justin Reed NØUJQ; 419 kB PDF file. Yet another method of connecting an external controller to an MSF5000 station. Someone found this article on the web and sent it to us anonymously. Includes an addendum that explains why the Gen Tx Data inputs may not work initially and a couple of ways to fix this situation.
	Adding Simple DTMF On/Off Control to an MSF5000 900 MHz Station   by Robert W. Meister WA1MIK Multi-digit DTMF control was desired for the New Jersey repeaters. Initially designed to work on a digital-capable MSF5000 station with a TTRC, you could adapt the connections to work on an analog or digital station without requiring a TTRC.
	A summary of Interfacing Information for the Analog MSF5000 stations   by Robert W. Meister WA1MIK A collection of the minimal signals needed to interface an external repeater controller to the analog (CLB) stations. Companion to the article below.
	A summary of Interfacing Information for the Digital MSF5000 stations   by Robert W. Meister WA1MIK A collection of the minimal signals needed to interface an external repeater controller to the digital (CXB) stations. Companion to the article above.
	Digital-Capable and Analog-Plus SSCB Signal List   compiled by Robert W. Meister WA1MIK The schematic diagram for the SSCB is nine pages long, and all but one fold out. Signals jump around from sheet to sheet and it's hard to figure out where they all go or come from. One day many years ago I got tired of searching so I marked my schematic and transcribed the information. Recently I added all the signals that come and go via the SSCB connectors. The tables in this article go along with the schematic diagram, a 460 kB PDF file; a link to it can be found in the article or here.
	The above interfacing articles are representative of several different repeater controller models. If your particular model isn't listed above, that doesn't mean it can't be interfaced to an MSF5000 station. Most controllers require the same five or six basic signals plus ground and controller power. There is sufficient information in the articles above to let you mix and match controllers from all major manufacturers.

Programming Articles:

	RSS Programming of the MSF for Repeater use   By Robert W. Meister WA1MIK This article walks you through all the settings to the MSF internal controller that are necessary to have an external repeater controller talk to it, then tells you what to change to utilize an external controller via the MRTI interface using the cable described in the above article. While the author used a CAT-200B / CAT-250 series controller, most other controllers can be interfaced using this information.
	Programming the TX Idle Frequency for Repeaters   By Robert W. Meister WA1MIK The MSF5000 suffers the same problem as a number of other stations: the default TX Idle Frequency is the same as the TX Frequency, which means your handheld (or any other radio) will unsquelch whenever you are near near the repeater. This article tells you how to deal with this situation.
	Controlling the MSF station transmitter PL encoder   By Lou Harris N1UEC This article takes you through some usually-overlooked RSS programming options that allow you to key the station PL encoder with COR, ANDed COR and PL decode, or an external logic level (perhaps a digital output from an external repeater controller like the Scom 7330). This eliminates any need to hack and slash any PCB traces. This bit of clever programming really simplifies linking methods that depend on keying the PL encoder on the repeater transmitter (as many IRLP systems do). This article also suggests a method to get a separate RX PL Detect signal out of the station for those controllers that seem to need it.
	Making a Programming Cable for a Digital-Capable station   by Robert W. Meister WA1MIK Details on connectors and signals to make your own radio-to-RIB cable for use on RSS-programmed digital-capable stations.
	Programming Information for the Analog MSF5000 stations   by Robert W. Meister WA1MIK These stations use EPROMs and require the R-1800 or R-1801 suitcase programmer. Here's a step-by-step run-through of the various parameters used to create or modify your code plug EPROM.
	Multi-Coded Squelch (MCS) Programming Experience with an Analog MSF5000 repeater   by Robin Feil W7MSE One user's experience programming both the repeater and the MCS option using a suitcase programmer.

900 MHz Station Articles:

	Note that the warmup drift on the 800, or 896 MHz (also known as 900 MHz) stations is more than the channel spacing... You REALLY need a high stability oscillator to make one of these useful.
	MSF5000 900 MHz Repeater Ordeal   by Robert W. Meister WA1MIK One group's ordeal getting a bunch of the New Jersey repeaters functioning. Also includes performance tests on the 5 MHz ovenized oscillators that were required to make each of these a stand-alone repeater. This article is a work-in-progress and will be amended as necessary. (updates are welcome!)
	MSF5000 900 MHz Miscellaneous Adjustments   by Robert W. Meister WA1MIK An addendum to the above article that provides helpful information and procedures for several critical adjustments to the 900 MHz repeater stations.
	MSF5000 900 MHz Repeater Conversion   by Mark A. Tomany N9WYS Another group's ordeal getting a few of the New Jersey repeaters functioning. Mark added a duplexer inside his station; read more about that in his article below.
	Adding an Internal Duplexer to the 900 MHz Repeater Stations   by Mark A. Tomany N9WYS Mark also had one of the New Jersey 900 MHz repeaters, but wanted to make it totally self-contained. He managed to innovatively squeeze a duplexer inside the cabinet. This article describes what he went through.
	Disabling HearClear on the MSF5000 900 MHz Repeaters   by Robert W. Meister WA1MIK Faster than a speeding bullet. More powerful than a locomotive. A few jumper changes on a CLB station and an unexpected result of a programming change to a GLB station totally disables the HearClear circuitry (compressor, expander, flutter-fighter) on these otherwise fine repeaters. Read on, McDuff.

Modifications, Repairs, and PSBs:

	You should verify that the 3-pin 2-way jumpers on the SSCB and TTRC are set to their default positions before doing any modifications. The articles below make no mention of these jumpers unless they have to be changed. The default position is indicated by a white silk-screened bracket over or near the jumper.
	Extracting Boards from the MSF5000 Plastic Control Tray   by Robert W. Meister WA1MIK It's not obvious how to get the boards out of the tray and the 20+ year old plastic is brittle and easily broken. This article gives you the secrets of how to physically remove the SSCB or TTRC boards from analog or digital MSF5000 or PURC5000 stations.
	Removing a Secure board from an MSF5000 station   by Robert W. Meister WA1MIK A simple step-by-step procedure that tells you how to electronically and physically remove the secure board from a digital-capable station. Also applicable to disconnecting the TTRC board. Read the above article first(!) to physically extract the SSCB or TTRC boards.
	How to get a CXB Secure-capable Station Control Board to work in a CLB station   by Robert W. Meister WA1MIK The CLB station can be upgraded with an SSCB board (the CXB control board) which converts it from an EPROM to RSS programming, but you need to get +5vDC to the rest of the station. This article tells you why this is so, and how to fix it.
	How to use the MSF5000 power amplifier stand-alone   by Robert W. Meister WA1MIK Enough people have asked how to do this. Not much to it, just a few precautions. Put that spare VHF, UHF, or 900 MHz power amp and power supply to good use.
	How to make the MSF5000 work without a power amplifier   by Robert W. Meister WA1MIK This is complementary to the previous article. It explains what I did to get a digital-capable UHF station to transmit without its power amplifier attached.
	MSF5000 PA Molex Connectors   By Robert W. Meister WA1MIK Documentation for the 6-pin Molex connector wiring for the cables that run between the power amplifiers and the RF Tray.
	Accessing the electronic adjustments in the digital-capable MSF5000 station   by Robert W. Meister WA1MIK A quick summary of the EEPots and how to adjust them via RSS or the front panel.
	Making VHF VCOs go down to 144 MHz   by Scott Hilton NØOBA and Paul Thompson WØOD These fellows had several range-2 stations that just refused to operate below 146 MHz. They found a rather easy modification to the VCOs that results in coverage down to 144 MHz.
	Reducing the PL Deviation of MSF5000 Stations   by Robert W. Meister WA1MIK If your station's PL deviation level is too high, there's no pot you can adjust to change it. You can reduce the PL deviation by adding one or two resistors (or the missing pot) on the top of the control board. There's info here for both the analog (CLB) and digital (CXB) stations.
	Connecting Fans to MSF5000 Stations   by Robert W. Meister WA1MIK Often these stations had fans that were removed (cable and all) or you want to add a fan to a station that never had one. Several people asked where to connect the cable. This article shows you the elusive DC fan power connection points, obvious once you know where to look.
	Building an MSF5000 Adapter Cable for the R1033 Test Set   by Anthony Stump KE4KQI Here's a simple to make adapter cable that lets you use an R1033 test set with an MSF5000 station. It's better than lugging multiple test sets around, especially if you've got other stations that already use the R1033 test set.
	Adding a Preamp to an MSF5000 Station   by Robert W. Meister WA1MIK A preamp can often improve a repeater's reception, but too much gain will cause more harm than good. This article shows several configurations and explains why you need to be careful when adding a preamp, and what you can do to reduce the gain.
	Replacing the Electrolytic Capacitors on the MSF5000 Uniboard and Injection Amplifier   by Robert W. Meister WA1MIK All sorts of odd problems can crop up, such as the VCOs not locking, the receiver hearing strange signals, etc. These are often due to failing electrolytic capacitors on the Uniboard. After 20 years, these are starting to go bad. A parts list is provided. You might as well replace the two electrolytic caps on the injection amplifier if your station has some.
	Replacing the Pots on the MSF5000 Uniboard   by Robert W. Meister WA1MIK The pots WILL go bad or break eventually. This article shows you some replacements, which one to choose, and why. A parts list is provided. You might as well replace the electrolytic capacitors while you've got the board out; see the "caps" article above.
	Replacing the Tantalum Capacitors on the MSF5000 IPA/REG Board   by Robert W. Meister WA1MIK These caps often short out, catch fire, and will burn up a foil trace on the Uniboard. They can easily be replaced and you should do this before they go bad and cause major damage.
	Replacing the Electrolytic Capacitor on the MSF5000 Inter-Connect Board   by Robert W. Meister WA1MIK It's just one cap on the 5 volt DC line, but you have to take a lot apart to get to it, as it's under the RF Tray.
	There are a few electrolytic capacitors on the MSF5000 digital-capable Secure Station Control Board (SSCB) and Trunked Tone Remote Control board (TTRC), mainly used for power supply bypass and audio coupling. There are also several on the analog Station Control Module (SCM) in the power supply section. Any of these can leak. There is currently no article covering replacement of these capacitors mainly due to the different models of boards as well as the difficulty of removing and reinstalling the front escutcheons and boards in the plastic control tray.
	Product Support Bulletins   A collection of Product Support Bulletins (PSBs) for the MSF5000 and PURC5000 stations. Many of these PSBs offered board replacement, but since these stations are discontinued and support and parts are no longer available, you're on your own as far as these changes go.

Link Receiver Modification Articles:

	Interfacing the PURC5000 Link Receiver   by Robert W. Meister WA1MIK I found this 72 MHz link receiver on a popular auction site. I had a manual for it so I took it all apart and documented the available signals.
	Adding a Speaker and Audio Amplifier to the PURC5000 Link Receiver   by Robert W. Meister WA1MIK A follow-up / companion article to the one above. It's now a very useful stand-alone bench tune-up chassis.
	Link Receiver Flat Audio/Squelch board TRN5363A   2.4 MB PDF file I had a problem with mine so I scanned the schematic, parts list, and X-ray view. Other than a few de-emphasis parts, this board is the same as the TRN6006A or TRN6007A and either of them can be made to be converted to "flat".

Error Codes, Alarm Codes, MUXBus Signals:

	Analog and digital error and alarm codes   Compiled by Robert W. Meister WA1MIK; 81 kB PDF file. This info was obtained from the RSS HELP file plus several instruction manuals. It also includes the blinking display and LED codes as well as the audible beeping alarm codes.
	Digital error codes, probable causes, and corrective actions   Compiled by Robert W. Meister WA1MIK; 180 kB PDF file. This article was derived from a PDF file sent to Repeater-Builder. It was converted to RTF, then turned into a DOC file, where the tables were converted to text, straightened out, turned back to tables, then heavily edited and standardized.
	MSF5000 MUXbus Signals   Compiled by Robert W. Meister WA1MIK; 90 kB PDF file. This began life as a 12-page PDF file sent to Repeater-Builder. The text was put into a new document, reformatted, corrected, and turned back into a PDF file.
	Digital-Capable and Analog-Plus SSCB controls and indicators   Compiled by Robert W. Meister WA1MIK; 110 kB PDF file. Most of the info came from chapter 2 of the Instruction Manual. It was re-typed and formatted to make more sense. More information may be added as the need arises or time is available.
	Digital-Capable and Analog-Plus SSCB Test Points   Compiled by Robert W. Meister WA1MIK; 3.1 MB PDF file. A compilation of the info that's present in the various SSCB schematic files for those people who are not willing to read or do any research on their own.

	MSF5000 900 MHz Model Chart (PDF)   Submitted by Eric Lemmon WB6FLY; 1.2 MB PDF file.

Internal Filter/Duplexer Documentation:

	Combining Tee UHF Duplexer cable (PDF)   Submitted by Eric Lemmon WB6FLY; 54 kB PDF file. This write-up describes the six UHF duplexing cables: coded red, pink, gray, orange, green, and yellow. The first four are for the 403-435 MHz range, the last two are for are for 435-475 MHz. The actual measurements for the green and yellow (the two most common) cables can be found in the detailed drawings below. Note that the UHF duplexing cables all exhibit a not-insignificant and measurable amount of desense. If you want a top-performing UHF repeater you will want to replace the Tee cable with the TKN8314 Kit (or make up a kit yourself) and use an external 6-cavity duplexer (or acquire a taller/larger cabinet and put the duplexer inside the cabinet).
	TLE5732A Green Tee cable (PDF)   Submitted by Eric Lemmon WB6FLY; 69 kB PDF file. This cable handles UHF stations with the transmitter frequency below the receiver frequency (i.e. an "in-high, out-low" station).
	TLE5772A Yellow Tee cable (PDF)   Submitted by Eric Lemmon WB6FLY; 51 kB PDF file. This cable handles UHF stations with the transmitter frequency above the receiver frequency (i.e. an "in-low, out-high" station).
	TKN8314A Conversion Kit - 435 to 475 MHz This kit was used to replace the TLE5732A or TLE5772A when converting from a "Tee" cable to a real duplexer. Click here for a photo. The kit consists of two cables that you can make yourself - a seven inch (about 17 cm) N-Male to chassis mount N-female (for the transmitter), and a 22 inch (about 55 cm) right-angle SMA-male to chassis mount N-female (for the receiver). The N-female connectors get mounted to the side panel of the cabinet.
	You can eliminate the internal filter/duplexer by connecting the IPA output (N-male) connector to the PA input (N-male) connector with an N-female barrel adapter. That's how the factory connects the two in repeaters without the internal filter/duplexer. The PA output then goes directly to the TX output jack on the side panel of the cabinet. On base stations, the PA output goes to a low-pass filter then to the antenna relay. The above conversion kit provides the PA output cable; you just need the barrel adapter to make the job complete. You will also need to readjust the PA output power after reconfiguring the station, because the internal filter/duplexer adds a few dB of loss to the signal path.

Analog Station Programming Services:

A few enterprising people have figured out SOME of the code plug layout and even have a program that will modify some items in the EPROM. This web page has the information.

The following commercial businesses or private individuals claim to provide analog station EPROM programming services. You may have to send some your old EPROM (2732 family chips are starting to become pure unobtanium). If you have your own EPROM burner and chips you can ask them to email you a PROM image file. If anyone has figured out the layout of the bits in the PROM please let us know.

Note that (supposedly) VHF station code plugs can only be made at the Motorola factory or repair depot; the suitcase programmer is incapable of generating a code plug for any models except UHF, 800, or 896 MHz (also known as 900 MHz). Likewise if you've figured out how to burn a VHF PROM please let us know.

EPROM speed doesn't seem to be a big deal with the R1801 programmer. 2732A up through 2732F EPROMs should all work. Most people still have an ample supply of EPROMs they can sell to prospective customers.

27C32 EPROMs may or may not work. It depends on the manufacturer and the programming firmware and hardware. Some will do it, some won't.

If you have an existing EPROM, the programmer can read the info that's already there, saving the person doing the work from keying in all the existing data, thus lowering the programming cost. If the programmer supplies a new EPROM, he has to enter a lot more information and therefore charge more for the time involved. Make sure you provide ALL programming information to minimize the back-and-forth programming trips and expenses.

Contact any of these people via their web sites or e-mail addresses. All of them were alive and well and still programming MSF5000s as of June 7, 2016. Some of these people may give amateur radio operators a discount, if they mention this ahead of time. It never hurts to ask nicely. Repeater-Builder makes no claims as to the reliability or quality of the work performed by any of these operations.

MSF Station and Metering Panel Toggle Switches:

From an email to repeater-builder from Jeff Liebermann AE6KS:

Broken toggle switches are epidemic on the MSF5000 and its TLN2418A and TLN2419A test sets. The problem is that the length of the original toggle arm is too long and is easily broken. The stock length is 10mm, but I've also included the 5mm long toggles for those that want to fix the problem. Click on the links to see a photo of the switch.

Digikey Part Number	C&K Part Number	Toggle Length (mm)	Used In

The MSF Manual Library:

Most of these manuals are No Longer Available from Motorola, or are limited to whatever is remaining in inventory. A good portion of the list below is courtesy Eric Lemmon WB6FLY; he provided us an update in June of 2009.

Some of the manuals sections labeled "...from The MSF5000 Instruction Manual for the analog station only." are incomplete. That's what was sent to us. Remember that the Power Amplifier, the Power Supply, and most of the RF Tray are the same on the analog and digital-capable stations, so check some other manuals before giving up.

6881092E90	Service Manual CXB / RLB 900 MHz, compliments of Brian Boyle WBØYLE. 5.9 MB PDF file. This is the entire manual and is as good a scan as I've ever seen, and all schematics are full-width, full-page. Note that the original manual only had schematics for the Control Tray (SSCB, TTRC, Secure boards), Uniboard, and Interconnect Board. The Power Amplifier(s), Power Supplies, and everything else in the RF Tray is barely documented. SSCB boards: TLN3384 (replaced TLN3182, TLN3183), TLN3385 (replaced TLN3189, TLN3319), TLN3386 (replaced TLN3204, TLN33320?), TLN3387 (replaced TLN3205, TLN3342). TTRC boards: TLN3312 (audio), TLN7754 (logic). Secure boards TLN3045, TLN3267. Uniboard (narrowband 2.5 kHz) models: TRN7197, TRN7881. Interconnect Board model: TRN7142.

6881094E30	Service Manual MSF5000 Power Supply The one-page Power Supply Model Chart (matrix) has its own section and Motorola thought it was SO important they didn't even include it in the manual's index. That page, with model and kit (board/module) numbers, has been scanned and can be found here as a 57 kB PDF file. Note that this manual only covers the most current equipment so a lot of older (necessary) information is missing. Motorola seems to have wanted owners to "Use The Force" to figure out some things, because there are errors, omissions, and inconsistencies throughout the manual. The relevant pages for the VHF 120VAC 28V/14VDC battery-charging power supply TPN1271B have been scanned to a 3.9 MB PDF file that can be found here. A few other pages for the UHF 120VAC 14VDC battery-charging power supply TPN1185B have also been scanned to a 950 kB PDF file that can be found here. From an email to repeater-builder: This manual, which comes in a nice three-ring ring binder, contains tech data, schematics, and parts lists for all power supplies used in MSF5000 stations. Sixteen different AC-input power supplies are included, as well as two DC-input power supplies. Battery reverting / charging supplies are also included. Curiously, the MSF5000 service manuals that I have do not have power supply information in them, but include a phrase like, "See the power supply manual for further information" without revealing the publication number.

Manuals for Metering Panels and Other Notes:

Manual P/N	Description
6881114E04-A	The TLN2418 Radio Metering Panel (RMP) is the same unit as the one below but without the LED matrix. Click here for a photo of the interior of the unit. As you can see from comparing the internal photos the internal circuit board is the same except that it is missing a lot of parts. Of course the case front panel is different too. This unit is sufficient to tune a CLB or JLB station, but if you EVER expect to work on a CXB or JXB station you will want the one with the LED matrix (the one below). (Photo courtesy of Jeff Liebermann AE6KS.) 5.9 MB PDF file.
6881143E03-D	The TLN2419 Diagnostic Metering Panel (DMP) has a meter, and a speaker (and the associated speaker amplifier) and a matrix of 64 individual LEDs that displays the multiplexed logic data buss (called the MUXbus in the MSF documentation). Click here for a photo of the interior of the unit. The TLN2419 DMP is fully backwards compatible with the TLN2418 RMP. If you are responsible for the operation and/or maintenance of any MSF stations you really want this unit instead of the one above!!! This is especially true if you have the digital station. (Photo courtesy of Jeff Liebermann AE6KS.) 1.5 MB PDF file.
6881127E69-O	The TLN2418A Radio Metering Panel (RMP) and TLN2419A Diagnostic Metering Panel (DMP) as one manual (late 1993) Has everything. Pages iv, 20, 22, 24, and 26 were blank and were not included. Scanned by WA1MIK. 3.8 MB PDF file.
Caution: Both of the metering panels have the same design flaw. Look at the speaker mounting on the interior photo of the TLN2418 referenced above. You will see that the speaker is held in place by four metal clips pushed onto plastic pegs that are molded into the face of the housing. All it takes is dropping the unit in such a way as the speaker shifts and shears one of the pegs off (and it doesn't take much). The loose speaker quickly shears the other pegs off and then you have loose metal clips and/or the speaker itself sliding around and contacting active electronics (which will not be too happy for that experience). The fix is to break the pegs off yourself and trim the stubs off with a single-edge razor blade, then drill the housing front for four 4-40 or 6-32 screws right where the pegs were, then use four large diameter flat washers under the screw heads (so the heads don't get pulled into or through the front plastic) and four more in place of the speaker clips. Some hardware stores stock "fender washers" - if yours does you may find that they work better. Four nylock nuts on top of the inside washers finish the job. Split lock washers are optional.

There may be other manuals out there; contributions of additional numbers, PDFs and descriptions are always welcome.

In May 2009, Motorola no longer had the firmware EPROM for the SSCB, TVN6055A. They did still list the latest firmware EPROM for the TTRC, TVN6056A, for about US$31. There's also no part number listed for the Secure board EPROM.
Does anyone have a good set of PROM image files?
