General Info
Figure out what programming cable you need. Take a look at the mic connector.
If you need a programming cable for the P1820AX portable repeater, just use a regular mobile programming cable and program each radio individually.
The pinout of the 15 pin accessory connector on the Spectra 900 is as follows:
If you want the pinouts of the connectors on other Spectra models, refer to the installation diagrams at the bottom of the page.

If you have an Astro Spectra, you will want to look at the Astro Mobile page too.
Certain Spectra's like the Smartnet or Securenet radios don't have scan. You can't enable it in anyway. The board inside the radio that controls the scan feature is not present in the radio.
The scanning features on older radios is part of the programming in the MLM module. If its not in the MLM, and you want to get it, you have to 'pay' for a MLM with scan in it from Motorola. The RSS won't unlock it, even though the RSS knows about scanning.
If you are hoping to find a way to get a Spectra to scan more than 16 channels, I think you will want to give up for now. We have yet to hear any method of doing this. However, should someone find a way, please let us know and we will post the results. BTW, if your radio is capable of zones, you can have a scanlist for each zone...
You can convert a Maxtrac DTMF mic for use on a Spectra by changing the cord, color for color, clipping R18 and adding jumper JU1. Note that you can get an almost identical schematic of the boards in a Maxtrac DTMF mic from the MCX1000 VHF Service Manual.
The Spectra VRM 600 which has a modem capable of RD-LAP data built in the front of the Spectra dash radio and no functioning control head uses PIN 4 (SW B+) for ignition sense. The standard dash mount programming cable power lead needs to be changed from pin 5 to pin 4 for this radio. I believe this is because of lack of a front panel power switch.
If you want to connect a MDC1200 unit to a Spectra, you need this diagram.
If you are looking for the pinout of the HLN1196A Auxilliary Switch Panel, then you will want to look here.
Spectra's come in many frequency bandsplits, called Ranges. Below is a list of the available ranges for VHF and UHF.
- VHF
- Range-1 136-162 MHz
- Range-2 146-174 MHz
- UHF
- Range-1 403-433 MHz
- Range-2 438-470 MHz
- Range-3 450-482 MHz
- Range-4 482-512 MHz
You cannot tell the range of the radio just by looking at the model number, you will have to read the radio with RSS in order to figure out what frequency range it covers.
If you connect a 9000 head to a A5 Spectra, the display shows gibberish but most functions still work.
When connecting an A7 head to an A5 radio, all A5 functions work but the A7 only functions do not (direct mode access etc.).
If you need to make a cable to connect an A9 Control Head to a DEK, you will need this pinout:
This is for the 3080248L01 interface cable.
The pinout of the KVL to Spectra Cable is as follows (refer to the mic connector pinout above for proper pin orientation):
This should be the 01-82997T04 cable, which used to be the TKN8531.

Spectra Interconnect Boards
I am sure most of you are aware of the HLN6285 interconnect board for the Spectra radio. This is the newest board which will allow you to run an A4 head or the newer advanced heads on a Spectra with out the radio going into a hissy fit and keying up as soon as you turn on the radio.If you are discarding your HLN6058's and HLN6066's and buying the HLN6285, YOU WAISTING YOUR $38.00 PLUS SHIPPING!!!!
Take your your 6058's and 6066's and isolate pins 4,5,22,and 29. To find these pins, look at your interconnect board while it is still in the radio after taking off the control head. They will be the pins at the top of the board, not to be confused with the lower black plug which the control head mates with.
Starting from the top row of pins at the very left which will be pin 1. As you get to pin 6 you will see that pin 7 is missing and then continues to pin 8 all the way to the far right which will be pin 19. Pin 20 starts at the bottom left bellow pin 1 and proceeds to the far right which will be pin 38.
You can cut the traces to each pin or just unsolder it and remove it like a bad tooth.
You now have an HLN6285.
Converting a UHF Spectra for Amateur use
The older versions of Spectra software wouldn't allow a 450-512 MHz radio to go below 449MHz. The latest Spectra RSS allows programming to 440. You may have to retune the VCO to get the radio to 'lock' on freqs below 440.5 MHz in receive mode. This version of RSS also lets you program down to 140 MHz on the 146-174 MHz bandsplit radios.
If you need to modify your RSS to open it up to the ham band, then you will need to go here first.
The VCO modifications are covered here.
Converting a 900 MHz Spectra for Amateur use
Okay, here's what we've been told should work for converting a 900 MHz Spectra for use in the ham band.
You will want to program all your conventional channels with Hear Clear and the compander options turned OFF.
Then, you need to program some frequencies into your radio. You will no doubt find that normally the RSS will not allow you to enter frequencies that will work in the ham band. You will need to modify your RSS in order to get it to accept these out of band frequencies. For the out of band modifications, you will want to click here.
You may have heard references to a 'SP' version of Spectra RSS, like SP06.00.10 RSS. There is some doubt as to whether this software really exists, or not. No one has been able to produce much concrete evidence. While it may work, modifying the normal RSS is probably a better idea.
For all those who have told you that you can enter the out of band frequencies with Lab RSS, they're lying. There have been many people who have tried, and they all come up with the same result... 'Value outside range for this model. Please consult service manual.'
You are also going to need to do some hardware modifications to the RF section of the radio. You can use the following procedure to modify the VCO, or you can click here for a different and more comprehensive procedure.
In order to get the VCO to lock, you need to play with resistor values (refer to schematic for resistor placement) in order to get the correct value to avoid a FAIL 001.
To get 5khz deviation on TX, solder .003 mfd across C651. You will get over 5 kHz TX deviation, so you must adjust the deviation in RSS to compensate.
For better receive response, you must replace the filters in the front end. Remove FL6301 and FL6302 (they are 7.5 kHz BW) and replace them with Motorola part# 91-80297k05, they are 12 khz BW. The filters are located in the center of the RF board, they are the blue squares. Be careful when de-soldering them, the traces are VERY small.
Corrupt Codeplugs
It appears that some Spectra's, when loaded with a corrupt codeplug, give the error FL01/82. Others lock themself into a repeating SELF CHK loop which is near impossible to do any more programming with.
We've been told that with lab software that you can get it out of this loop. You have to change the serial number of the radio, re-initialize and tune the radio, then read the codeplug and send it back to the radio in order to stop the repeating loop.
After changing the serial number the display reads FL01/82 (which is a corrupted codeplug), just keep going with the above procedure, and everything should be fine.
There is also something else you might try. We have heard that when the radio is stuck in this loop, if you play with the HOME and DIM buttons, you might be able to get the radio to stop looping and stay on a mode. You might have to try this a few times to get the timing right.
Once you have the radio stopped from looping, try dumping a good codeplug into it or cloning your backup codeplug to it (again it may take a few tries). If you're lucky, you may not have to go through the above procedure.
If this fails, you can also try the following. Hook up the Spectra to the RIB in the normal way for programming. Connect the Spectra to a variable voltage power supply, ideally one where you can switch the output voltage. Now power up the Spectra at about 6 or 7 volts. When the self check display first comes up quickly switch the power supply to the regular 12 volt level and the Spectra may stay on.
The MLM Board
Ok, here is a detailed explanation of what the MLM is and does in the Spectra, and what is involved in trying to upgrade them properly.
The MLM (Memory Logic Module) board contains the firmware and programming info as to what the radio can and will do. The MLM is located under this shield on the logic board. With the shield off, you can see the sticker which contains the serial number programmed in the MLM, as well as the firmware version (in this case, v6.15). If you pull the MLM out of the header on the logic board, you get a unit that looks like this. You will notice the two 27C512's which contain the firmware for the radio and the 28C64 which contains the codeplug data.
Motorola Spectra Manual
Most people who try to upgrade a Spectra (ie. try and make a Spectra 800 B5 into a C9) will not be 100% successful when using lab to force feed a C9 archive into a B5. The reason is, if the MLM board version of the C9 is say a 5.06 and the B5 MLM board you are trying to convert is a 3.22, you will not be successful because the lower version board does not have the all the chips and memory to hold all the info.
If you continue to try and trick the radio into taking the info, you will probably end up with a FAIL 01/90 when you turn the radio on and it will not stay on.
The correct way to upgrade the Spectra is to find as many Spectras as you can with all the features in the radio in all the band splits and check the MLM boards. If they are version 5.00 or higher, then you will want to extract the firmware out of them and save them.
The way to do this is to take out the MLM board and look at the chip side with the pins on the right side of the board. You will have to take off the first chip on the far left and use a programmer to read the info and then save it as a bin file and label it (ie. 800 C9 LEFT). Put this chip back on the board and remove the second chip and do the same, labeling it too (ie. 800 C9 RIGHT).
These are the firmware IC's which hold all the info such as, SECURNET, ZONE, 9000 CONTROL HEAD OPTIONS, ect. These chips are usually 27C512's and are EPROMS which can only be written once.
Now you need to remove the far right chip which is usually a 28C64. The procedure is the same as the previous (read it, and save the file with a name like 800 C9 MAIN). This chip is an EEPROM which can be erased and re-written. It contains information such as MODEL #, SERIAL#, codeplug data, ect.
If you have ever noticed when you use lab and force feed one codeplug into another with some success, you usually have to program from the archive to make any changes. If you tried reading the radio after upgrading with lab, you will usually loose all the features because all you did was store enough information into the the MAIN chip to make a couple of things work, but not always 100%.
The theory of the MLM board is when you read you're radio via RSS, you have read all three chips, the LEFT and RIGHT tell you what you can do and the MAIN is where you store all you're info such as, FREQUENCY, PL, MDC, HOME MODE, ect.
Now, you'd figure that if you replaced the firmware on your MLM with the newer firmware and replaced the codeplug EEPROM with a blank one, you should have a nice, new, blanked board, right? Wrong. If you put a blank chip on the board, you will get FAIL 01/90. The 28C64 also contains the info to fire up the Selfcheck and make the control head work. We are trying to figure out just what the minimum info the codeplug EEPROM needs in it to make the radio function so that you can get the proper model and serial number in it for your radio.
FAIL 01/90
We must point out that we do not claim this will work every time especially if you are trying to alter an MLM for extra features.
While reprogramming a Spectra, power accidently got killed to the radio. You know what happened next... FAIL 01/90.
The next day, we decided to do some programming on a VHF Syntor X9000. Well everything was on the bench, including the Spectra that got toasted. Not paying attention to what we were doing, everything was hooked up, and when we turned on the 9000 control head, some weird fail codes appeared.
After tracing the cable from the head, we realized it was connected to the Spectra. We had accidently put the Syntor X9000 head on the Spectra. More importantly, we noticed that the radio was no longer the the dreaded FAIL 01/90. Being curious, we put the A7 head back on the Spectra, and sure enough got the FAIL 01/90 cycle.
We put the 9000 head back on and went through the standard procedures like re-entering the serial number and reprogramming the radio. Well it worked. The radio came back to life.
This was tried on a couple different radios (scrambling them and recovering them). Each time when putting the Syntor X9000 head on the radio, it would cause the radio to stay on so that we could refresh the MLM back to its original state.
Again, we do not recommend this practice for modifying an MLM, only to as a last resort to try and restore it.
There are some other things to check if you are getting a FAIL 01/90. These are listed below:
If you are using it as the second head, change it to the primary and see if it still fails. If it works, you need a new dual interconnect port for your remotes.
If that is not the problem, then check all the pins on the head. Make sure all of them are getting continuity on the board and through the cable. I have had some that had bad pins and I ended up flowing some solder on them to get them to make better contact when the cable was hooked up.
You might also check the solder connections on the control head board, and trace them through out the head. You might have a failed SMD somewhere that is keeping a signal from getting through. I recently picked up a 1066 that would not key up. I ended up putting a jumper across the PTT pin at the mic connector to the PTT line on the cable connector. I found that alot of the A9 heads start to go bad at the pin connectors and the layered boards because to much flexing and pressure applied when constantly removing or cheap installation.
Spectra Systems 9000 Control Heads
There are a number of Spectra Systems 9000 (A9) control heads available. The part numbers we've seen are as follows:
| Part Number | Subs To | Description |
| HCN1045B | H1591A | NPD Clear Replacement |
| HCN1063A | H1591A | |
| HCN1066F | H1593A | Zone/Mode/Vol Replacement |
| HCN1071C | H1596A | Rear NPD Replacement |
| HCN1033D | HCN1073E | X9000 Head |
| HCN1063B | X9000 Head |
Now, you're probably wondering what all this means. Well, the 'Clear NPD Replacement' is a normal replacement head from National Parts Division that has all buttons installed, but they are all clear (no labels).
The HCN1066 head is a Spectra head that has rocker positions for Zone, Mode, and Volume. This is kind of nice if you have a radio that is zone capable, then you can have a properly labeled zone rocker rather than having to use a couple of arrow keys.
The HCN1071 head is listed as a rear head, but it works just fine when programmed as a front head. Even in the Front/Rear Installation Manual, it states that there is no electrical difference between the front and rear heads, only the programming of the EEPROM (through RSS).
A note about the part number suffixes. The last letter on the end of the part number usually denotes the revision or release level of the part. So, while a HCN1066F and HCN1066G are exactly the same head, the G version was released later than the F version. I am making a note of this because when you search the Motorola Parts Database for part numbers, they may not have all the revisions listed, so your search may turn up a blank. The way around this is to use a * in place of the revision letter. The search will be a lot slower, but then you will see all the versions in the database as well as the substitute part numbers for each of them.
If anyone else has any part numbers of Systems 9000 heads that are confirmed to work with the Spectra, please email us with the part number and description so we can add it to the table.
Do you have a Spectra 9000 head that is VERY dead? Pull it apart and check the aluminum electrolytic capacitors on the back of the board. They have been known to leak and cause traces to open up. If you replace them, clean the board, and check/repair the traces, you will probably fix the problem.

| Good Regulated 9.6V, 5V, Constant Reset | Check Paths From Cmd. Bd. to Control Head (BUS +/-, Busy, Etc) |
| Works Without HearClear Board Installed | F0500 Open on Cmd. Board |
And, if you run into the Fail 01/92 error, you may be able to clear it with Lab RSS. There is supposed to be a 'reset micro' option in there somewhere that may help.

Emergency Button Kit
There is also available an emergency button kit, HLN6061D. It contains the following parts:
The first two parts make up a button that has a raised guard around it, with a red plunger in the center to prevent accidental activation.
Radio Installation Diagrams
Here are some various installation diagrams and schematics for the installation of Spectra radios.
*Has plugs for the DEK and Switchbox. From manual 68P81093C18-O.
If you have a burning desire to know what the layout of the A9 remote cable make-up is, see below:
If you are very patient, you CAN re-assemble a cut control cable by re-soldering it back together. Start by trimming and preparing the ends of each side of the cable kind of like this. Then, you cut a whole bunch of shrink tubing and start soldering and insulating as you go. When you are done, you'll have something that looks like this. The only thing left is to nicely shrink tube the entire bundle (make sure you think of that ahead of time :) ) and test it out. As long as you go color for color, it should function just fine.
Connecting a Spectra to a Command Data Encoder
Here are the installation and configuration instructions for connecting a Command Data Encoder to the Spectra
- 1) On the interconnect board in the radio remove jumper (JU621).
- 2) On the same interconnect board install a jumper into the (JU624) position.
- 3) Install a jumper into the (JU650) position.
- 4) Inside the control head install a jumper from Pin 46 on the control cable connector to Pin 24 on the microphone connector.
The Command Data encoder unit should be connected to the J6 connector on the Spectra radio.

Converting a Syntor X9000 VRS for a Spectra
It is possible to convert a VRS from a Syntor X9000 for use with the Spectra. The only thing that may be questionable is that mode steering to a Spectra Securenet mode may not work properly. This may just have been a programming issue.
The part number for the special low profile shield used by the Siren/PA and VRS combination in a single housing is 26-06360T01.
The VRS is located inside an External Options Housing or inside a Siren/PA housing.
To do the converstion, you will need a Spectra 'SP02' microprocessor. The part number is 01-06711T02. The Spectra 'SP02' microprocessor is used to convert Syntor X 9000 VRS 'SP01' into a Spectra 'SP02' VRS.
The VRS circuit board can be placed inside a Siren/PA housing. When this is done the large metal shield in the original Siren/PA must be replaced with the low profile shield above. This part was a special factory build part and Motorola only recently made it available as an individual part. R36 and C102 are removed from the Siren/PA board to attach the VRS circuit board power wires (they attach to the same place they were in the original External Options Housing).
System Watch II and Spectra RF Modem
Anytime a Spectra that is in the RF Modem mode and is accessed with RSS will drop out of the RF Modem mode. This includes just reading the codeplug with RSS.
In order to place it back into the RF Modem mode, the following steps must be done in RSS (Using RSS ver. R06.00.05 (RVN4001N)):
- [F2] Service & Alignment..
- [F8] Service Aids
- [F3] Enable RF Modem
- [F8] (Enable RF Modem)
- Turn OFF Spectra
- Disconnect Radio
- Hook Radio up to the SystemWatch RIM*
- Power radio, RIM and SystemWatch back up
- Done !
Caution: After enabling RF Modem mode (steps 1-4 above), DON'T DO ANYTHING ELSE WITH RSS to this radio or you will have to re-enable it again!!
Spectra DTMF Decode
The Spectra DTMF decoder option manual is titled 'Model W946ALSP' and is part number 6807992D56.
It documents the HLN6151A DTMF decoder circuit (schematic and parts list), operation, RSS defaults, theory and troubleshooting. In spite of its price, it only has 12 pages (6 pieces of paper total). The circuit board only has 2 ICs on it (DTMF decoder and shift register).
The 900 MHz radio HLN6150A Hear Clear circuit board also has a DTMF decoder circuit built into it (the Hear Clear circuit board hardware is documented in the Detailed Service manuals).
One of the above circuit boards can plug into the Spectra Command Board J501 connector.
The DTMF manual trouble shooting flow chart says the MLM software version needs to be 5.10 or higher to support DTMF decoding.
So it looks like you need a HLN6150A or HLN6151A circuit board and MLM version 5.10 software or higher to get a Spectra to decode DTMF.
Spectra Data Option
Option W308CASP is a flat audio option where TX audio and RX audio and PTT are put on the 15 pin connector... with NO pre-emphasis or de-emphasis on the audio.
You get near DC response on the audio and very flat response up to the upper 3 dB limit to 5+ kHz on a 25 kHz channelized radio. This is good enough for 9600 GMSK data.
This info may be useful to those that want to do packet radio or other forms of data using a Spectra. Some of the service manuals identify this option so you can do it for yourself. It consists of moving some 0ohm smt jumpers in the radio.
The mic and speaker functions still work with this option.
There was another variant of this option with a different part number but it only differed in terms of audio levels.
Spectra Accessory Connector Interconnect Cable
There is a cable inside the radio that connects from the Command Board P0503 to the accessory connector and P0853 on the PA. The part number for this cable is 30-80239N02.
It is not referenced to in the Detailed Service Manual, at not least anywhere we can find. When it comes to trying to figure out what pins on the accessory connector connect to the Command Board, and where, that makes things difficult.
Presented below is the pinout of this cable.
| P0503 Command Board | P0853 PA | Description | P0503 Command Board | DB15 Accessory | Description |

| 23 | 10 | BUS - | |||
| 24 | 2 | Emergency | |||
| 25 | 9 | BUSY | |||
| 26 | 1 | TX Audio/Reset |
The descriptions given are those from the pins on the Command Board. As you can see, some of the accessory connector pins have multiple functions. The function depends on jumper configuration on the Command Board. The standard configuration for these pins is shown on the installation diagrams.
