This was originally put together when I got into the HT1250 200 MHz radios. They modified ok, but the way of doing it as suggested left much to be desired, and the DTMF pad didn't work and the radios were narrow band only.

Over time, I've gotten more into these with the CDM1250/1550 and other waris series radios. I've not seen any of the European ones, but I've been working with the US versions for FM service in ham radio.

What I've found is the radios features are determined by the "codeplug" settings. This is simply a packed (hex) data written into the eeprom chip of the radio containing tuning, feature and programing data. This is the same area the programing data from CPS is written in, but CPS is unable to change it. The majority of modification of these radios to amateur service is done with modifications to the codeplug. The codeplug layout appears to be the same for most US versions of the radios, but there are some which are different.

The cool things about these radios is any of the limited ones can be "changed" into the highend, or even more.

Every Waris radio can do the following:

  • 255 personalities only limited by the 16kb of eeprom space. If you load up a bunch of MDC and other crap, CPS will limit adding new channels.
  • MDC/QCII/DTMF signaling
  • LTR trunking
  • Passport (with the right board)
  • 4line portables can be flashed to do FPP/edit mode without special battery
  • Flexibility of band edges when re-aligned properly
  • it is impossible to "brick" a radio. You can fuck it up so it won't boot, but it can be recovered.
  • ability to flash the firmware between EU Select 5 calling and US MDC models (not done too much on this) Even MPT should be possible.
  • mobiles will support any control head, even the 4 line display from the GM380/1280.

Types of Radios


HT750 - No Display, 4 or 16 channels

HT1250 - One line display, multiple channels up to 128

HT1250ls - limited version of the HT1250, normally missing MDC on conventional

HT1550xls - 4 line display radio, 160 channels, VHF/UHF only

EX500 - No display, smaller submersible radio, 16 channels

EX560xls - one line, smaller submersible radio,

EX600 - one line

EX600xls - one line, 160 channels

CP200 - no display, 4/16 channels

CP200xls -

PR400 - VHF 1/VHF 2, UHF 1/UHF 2/UHF 3 - comes in 16, 32 or, 64 channels

GP series from EMEA

These have EMEA (Latin America/export) versions known as GP

GP340 - HT750

Note I got a GP340 in LB2 when I was in Germany. As they use the euro CPS for 5 tone I wanted to get it going as a US version with MDC and newer firmware. The 5 tone HT's all use 512k flash memory, not the 128k of the HT750/1250 (1550 is 512k), and I was able to flash it using the unofficial kit, then put a default codeplug in it. It took me trying a couple default codeplugs to find one that works. After this I flashed it to R05.18.01 using the normal tools.

What might be interesting would being able to convert the LB GP340 to HT1550 as the GP's all have the 512k Flash ram. A default code plug would need to be edited from an HT1550 for low-band. Theoretically this should work, the parts line up.

GP344 - EX500

GP360 - HT1250

GP366 - EX560xls

GP380 - HT1250

GP580 - HT1250 ls?

GP680 - MPT 1250

GP1280 - MPT 1550



These are the series most people see here in the USA. They will do analog voice and come in many different models determined by the control head.

There is no N head for these.

GM EMEA 5-Tone/MPT1327

These are 5 Tone or MPT radios and come in different models, determined by the control head.

GM140/GM340/GM640 - C control head GM160/GM360/GM660 - F control head GM380/GM1280 - N control head (4 line)


This is not really a waris radio, but the build is similar. These are tetra models for the EU market.

The 4 line control head on this will work on the Waris radios, but the fixed icons for the LCD are different. It may be possiable to replace the LCD module in this control head with the GM380 control head module (P/N 5164313B02) and get it back. I've found this doesn't really effect function, but the talkaround/scan/etc indicators are way different in the TETRA radio.

Control Heads

It's possible to put a 4 line control head on a Waris mobile. This can be the control head from the MTM700 as well, but the LCD ICONS will be different.

GM380 LCD Icons
MTM700 LCD Icons

4 Line Display Use

First ensure your display works before going further. If it's the MTM700 LCD or Display module, the Icons will be different, scan will show up as a period on it for example. The keys will be different and the Menu key can be especially confusing.

  • Check your codeplug
    • is the existing codeplug a Major version 3? Does it have an FDB2 size of 0x09? If not, you'll have to get a binary codeplug and push it into the radio that is
    • This is done by selecting a default codeplug that matches your needs closely. I find a code plug that has analog only, no LTR and the options I need. Then I edit this codeplug in a hex editor and past it from 0x280 to the end into the existing codeplug. Using the tools to convert this to an srec file makes it easy to open in CPS with out needing to write it to a radio.
    • once this is working how you like it, program it into the radio using Codeplug tool.
  • connect up your control head and enjoy!

Remote mount works with the 4 line head too. I've taken to calling this a CDM1850 :)

Option boards

Option boards are the keypad in the HT1250, and can be installed in the CDM mobile radios as well.

Known boards are below:

AAHLN9725C - Voice Storage Option board

AAHLN9729C - DTMF decode board

AAENLN4150A - Mandown board

The Mandown Option Board is compatible with all 5-Tone, MPT and MDC/Conv portable radios of the Professional Radio Series in all bands (except P040/P080 and GP320).

It is also operational with all connected original Motorola accessories for the GP Professional Radios Series portables.

Installation in any Intrinsically Safe (IS) radios will invalidate the radio’s IS approval (i.e. FM-radios).

WARIS Mandown OSS R01.01.01 2001-01-11 Programing Software - Mandown Option Board Service Software

Passport board - PTCB

The Passport Board was used in both HTs and Mobiles. Most (all?) 200 MHz radios will have them. It can be removed from the mobile and disabled if desired.

Removal is simple, just open it and remove it. I save the flex cables as they make great replacements in the HTs


Passport uses it own firmware and CPS to program the PTCB. There is a complex interaction of programing of the option board and the radio it self.

Unknown Boards

There was an API/developers guide a company could license from Motorola. Several companies made add ons for these, but I have very little information on them. I belive this is known as "Professional Radio Option Interface Specifications" or PROIS. Rotronix Ltd. was a company known to make a controller for this.

There is a manual "Motorola PROIS v2.03 Manual" which is mentioned in the LC828 manual. A copy of this would be awesome to have. This may have a part number 1202899J28

Here is a picture of one with a DB-9 connector on it. Any information on these would be appreciated.

Rotronix Ltd. made the LC828 which was a special radio based on a PROIS board and a waris radio.

LC828 interface manual - This has a complete document on the "Motorola Professional Portable Radio Interface Option Board(IOB) Manual". It includes a schematic of the board and parts list as well. This is the same board used in all the interfaces.

Computer controlled Radio Interface - CCRI - This is the Manual to the CCRI interface spoken by the Rotronix PROIS board. The mnaul says this is based on the CCRI protocol by T.L. Parker Ltd.

Here is a comment posted by the developer of this board on batlabs forum

Programming and Flash Cables

The CDM and HT series are programmed using windows based CPS. A rs-232 level converter is needed to talk to the radio, and in the OEM Motorola soultion consists of a Programming Test cable (AARKN4083/AARKN4074), a RIB (level converter) and a test box (RLN4460A/B).

<#gallery of shti>

The HT series program and flash via the 13 pin accessory port. The CDM mobiles program and flash via the back 20 pin accessory port or via the front RJ-50 (10 pin) connector. The font connector presents some issues when programming and flashing a unit with a remote head, and the rear connector should be used for that.

The CDM accessory cable connector is a TE AMP connector, Digi-key part number 104422-2-ND, and uses Digi-Key Part number A25989-ND for the pins.

Notes on the RIB based Cables

You should not use a RIB to Flash the radio at anything other than 9600 bps. Even then I've run into issues with this setup. Programing works well though.

A very strange issue popped up using the built in serial port on the Dell Latitude D830 with docking station. When using the docking station serial port the radio will "lock-up" and require the cable to be disconnected to be programed.

I've found the Prolific and FTDI serial adapters to work fine with the RIB for flashing/cptool. However the Prolific adapters have an issue in CPS unless they run the right version of the driver,

File:Prolific USB-to-Serial Comm Port 2303 VER del 17-04-2006 OK.zip

Notes on RIB-less Cables

RIB-less cables are the preferred way to work with the radio. These can be either serial or USB based. In the USB case it's simply a FTDI or Prolific serial port with a level converter.

I've used the following cables for programming

Be sure you use the proper drivers if using the prolific cable.

Flashing and Flash adapters

If you want to flash the radio you need to put it in bootstrap mode. This is done using a flash adapter that puts the CPU (68HC11) into a special mode. The flash program loads a boot loader/flash application via the serial port and then writes the new image to flash chip.

The US Waris unofficial upgrade kit is something that was built by possibly a internal Motorola programmer, or a hack based off the official upgrade kit. Using this tool you can load any of the images on any radio, but you must ensure the image selected is the same size as the flash chip. Note this tool requires all images and default codeplugs as srecord format.

The official upgrade kit includes default codeplugs, firmware images and boot images. These are in an encrypted format, and it appears the unofficial kit has decoded these as the included codeplugs/firmware.

Flash adapter for CDM1250 radio

220 HT1250ls and CDM 1550ls

This is the same as any other to modify to the amateur service from a software perspective. The issue is these radios are narrow band only on the receive path, as the 200 MHz band was never used for 25 KHz channels. Transmit will support wide band (and must be aligned for wide band first!) The IF filters simply need to be swapped with their wide band parts and wide band receive alignment performed.

Hardware Mod

Their are 3 filters in the radio, 1 at 44.85 MHz 1st IF and 2 at 455khz, 2nd IF.

In a VHF/UHF Waris there is a 15KHz filter at the 1st IF followed by a 15KHz filter at the second IF and then followed by another filter. It's this last filter that is switched between narrow and wide in the VHF/UHF radios. TX deviation is a setting in programming/alignment.

In the 220 version, there 1st IF Filter is the same, but it has a 12KHz and then a 9 KHz filter at the second IF.

I've changed out the second filters and found it works much better on the ham bands. You need to adjust the squelch for 20/25khz channels after doing this. The tuner software (2.00.02) will do this for the HT1250 only, it will not work with the mobiles. Use winabler to access the greyed out menus in tuner 2.16.

HT1250 Filters:

Function                         Part      Manu P/N      Moto P/N     Desc
220 front end     44.85MHz       FL3201    MXF45         9180022M10   4-pole +-7.5khz bandwidth
IF2 First filter  455KHz         FL3204    CFUCJ455F     9180468V04   4-pole 12khz                
IF2 filter narrow band filter    FL3206    CFWC455G      9180469V03   6-pole 9khz

The UHF handhelds use the same arrangement, but with a wider middle filter (1st @455). In wide band they switch only the 2nd 2nd IF filter to a narrow band filter.

uhf front end     44.85MHz       FL301    MXF45          9180022M11  
IF2 First filter  455KHz         FL302    CFUCJ455E      9180468V05   4-pole  *                
IF2 filter wide band filter      FL303    CFWC455E       9180469V05   6-pole  *
IF2 filter narrow band filter    FL304    CFWC455G       9180469V03   6-pole

You'll need to order the parts with the * from motorola parts for the 220 radios. The mobile and HT use the same filters.

In the HT the 1st IF is under the shield, and very hard to remove. I've not messed with it, as it appears to be the same part in the UHF, and doesn't look like it's limiting.

Based on the following codes for muratta filters

Muratta filters 
E is +- 7.5 (15)
F is +-6 (12)
G is +- 4.5 (9)

The 220 Filters are 12 and 9 Khz wide at the 2nd IF. Switching them to the E filters of the UHF HT1250 is rather easy, as they are just on the underside of the board, not under a shield. An under board heater with a hot air station makes this rather easy.

Ive found an under-board board pre-heater is mandatory to work with this and 630f at 7 l/m of airflow will prevent hurting the board/parts/

I've found the sensitivity to be a bit better and no squelch clipping on 3.2kc tone at 7khz of deviation (Most ham rigs on 220 have WIDE deviation!).

Pictures of CDM1550

These show the filter change out on a CDM 1550. Kapton tape is used to protect the adjacent parts as they will reflow and move. An underboard heater is used to bring the board up to 500f (260c) while a hot air wand is used to supply the last bit of heat needed.

Software mod

All this below is not needed. Check out using the UHF 450-527 Ham Band Mod for using waris.py and chirp.

Using Chirp is the way to do it and you can change everything. I typically set the signaling bits to FF enabling all signaling supported, but some radios may not work with this. Always read the radio and save the data before making changes. The data file format is the same binary on the radio EEPROM and use by cptool.

old way

This is easiest with CP tool and a hex editor.

First upgrade the Firmware using the firmware update. This will load the default codeplug back in the radio.

Read the radio using the CP tool and save the binary codeplug. I typically will read this from 0x0000 to 0x1000 which will capture the entire default codeplug (Tuning, Features, and Programing). Save this file and set is aside for safe keeping. If anything goes wrong, you can blow it back into the radio and restore it to defaults with out needing to retune.

If you want to use the pre-made binary codeplugs, if one exists, rather than edit your own you can go right to Writing the Modified Codeplug below.

Editing the Codeplug

Now open up a copy of this code plug and edit it based on the Codeplug Map for the feature blocks. This is from 0x280 to 0x2ff.

You'll need to change the following parts:

  1. Serial number, ASCII spaces are blank (optional)
  2. Channel step needs to be 0x01
  3. Upper Frequency: 0x5F50 for 225 MHz
  4. Signaling: 0xFF is everything enabled (MDC, QCII, DTMF) for trunking and conventional
  5. Conventional Personalities: 0xFF for 255 channels

Once this is done, be sure the checksum 8 on both FDB blocks are 5A. You will need to adjust the checksum bytes for this.

Writing the Modified Codeplug

Open this file with the CP tool and put 0x280 to 0x2ff into the radio, no need to write the entire file. This makes it easy to do many units at once, just blow the Feature Block in, while leaving the tuning and programing alone.

Codeplug tool with a fdb ready to be written to a HT1250

Tune the radio

You'll need to now tune the 20 and 25 KHz squelch settings in the tuner software. The issue here is the tuner software will not let you select the 20 and 25 KHz from the drop down menu. Using Winabler this can capture the tuner menu and enable these.

I use the auto squelch setup and found a good value is -127.5 dBm for hams. My radio is -124 dBm for 12db SINAD so this is about 6 dB SINAD at -128, very noisy but understandable. Auto tune makes this really easy. You can always program a button to set the squelch to tight in CPS.

I've found I needed to play with the RSSI settings too, as the S meter was setup for commercial strong signal service. I've only seen this with certian 220 radios.

It's also a good idea to check the frequency/modulation/power out alignments too. The CDM1550's from the New Jersey Turnpike all were aligned wrong for the power output, and we 20W out when set for 30W. Align it in tuner properly, and then use CPS to lower the power if you want.

If you've set the serial number to blank, it's a good time to set it to what you want in tuner before you disconnect.

Once you're done with all this, you should have a great radio that covers 216-225 MHz, wide band FM, MDC/QCII/DTMF, 30W power out, and damn sensitive squelch.

UHF 450-527 Ham Band Mod

The basic issue with modifying these radios to cover down to 440 by only adjusting the High & [[#Low Frequency|Low] Frequency settings in the feature region of the codeplug is the tuning for deviation/squelch/signaling/etc. is setup on 7 frequencies. When the radio tunes between two of these frequencies the value is interpolated based on the curve of the tuning values. For example deviation response will vary from 450 to 520 MHz, the same voltage at 450 will be an unacceptable amount of deviation at 520.

As the frequency "piers" only go down to 450 MHz, the radio has nothing to interpolate with if it's programed 440.450 MHz. This causes this interpolate calibration code to fail and deviation and other calibrations are all over the place. Luckily this is a rather easy fix.

Video of how to do the hex editing of the code plug from a HT1250ls 450-527.

There is a new way to do this using chirp and the plugin below:


video explaining the new way using chirp

Preselector Tuning

Using this procedure on a number of EX600xls radios has worked well, but some don't seam to work down at 440 on receive. I've found this to be due to the preselector alignment. Once this is re-aligned on the new frequencies in global tuner, the radios receive properly.

Since you have to load global tuner up anyways, it's worth checking the refference frequency oscillator warp. While not off much, the batch I've seen have been off 600-1000 Hz.

CDM Low Band Range 3 to 46-54 MHz

N9IAA has reported much success moving the CDM's to cover 46-54 MHz (from 42-50 MHz) after modifying the programing using chip and changing the following parts in yellow on this spreadsheet. A complete retuning is necessary of course.

HT 1550

The HT1550 was the high end portable at the time, they can do 160 channels (of course modifiable to 255), but were VHF/UHF only.

Dot Matrix LCD Repair

HT1550XLS LCD Missing Lines

Have missing lines on your HT1550 Dot Matrix LCD? Try this to bring your pixels back to life.

It's a risky repair but can salvage an otherwise junk LCD.

Edit mode (FPP)

The Front Pad Programming (Edit Mode/FPP) was an option on the 1550, but required a special government only battery. Recently I was able to work on the firmware and jump over this check. The crux of this is you cannot upgrade firmware without losing this, but as R05.18.01 is the last firmware made for the 4 line models, this shouldn't be an issue. You will need to use the US Waris Firmware Flashtool from the unofficial lab kit and the firmware image below.

Ensure you have edit mode enabled on the personality and enjoy editing without using the special battery.

Code Plug Map

This is based on the Srecord file loaded as binary

0x000 - 0x27f group, 5A checksum. 0x27f is the checksum byte
This group contains the tuning information for the radios.  
The frequencies it's aligned on are in the same format as the band limits.  
There are 3 groups of frequencies in here, not sure what they all do, but can confirm 
changing them all moved the tuning frequencies on a 6 meter CDM.
0x282 - 0x2D7 - group, needs to be 5A checksum, adjust 0x2D7 to make it.
0x285-0x28E - Serial number
0x291-0x2A0 - Model number, Blank should be spaces 0x20

0x2AC      Channel steps 
*0x01   - 12.5, 20 and 25 KHz
*0x05   - 12.5 only
0x2AF       Lower Frequency Limit 
0x2B1       Upper frequency limit 
Desired limit - Base freq (200mhz models the base freq is 103mhz) times 1000 then 
divided by 5. this gives you the new value in dec, you have to change it to hex 
216 MHz is 5848
225 MHZ is 5F50
58485F50 across both bytes

Below is only valid for the 3.08 codeplug tool codeplugs
0x2D8 to 0x2E9 - group, needs to be 5A checksum, adjust 0x2E9 to make it.

0x2E2 - Number of personalities is at in hex.    
*128 - 0x80
*160 - 0xA0
*255 - 0xFF
Below is only valid for the 2.08 codeplug tool codeplugs
0x2D8 to 0x2E4 - group, needs to be 5A checksum, adjust 0x2E4 to make it.

0x2E2 - Number of personalities is at in hex.    
*128 - 0x80
*160 - 0xA0
*255 - 0xFF

The 8 bit checksum must be 0x5A for this bit of code. Byte 0x2E9 is the checksum fix bit. Find the difference after editing between the checksum and 0x5A, then add or subtract this from the value in offset 0x2E9.


The CPS password is stored in plain text in the codeplug, while the radio lock password is a bit more involved.

My notes are based on a ht1250, so it might be a bit different.

Use the code plug tool to dump the radio to at least 0x400.

Open the resulting binary file in a hex editor and look at or around 0x33e to 0x345 (7 bytes). This is the CPS password. Read the radio with CPS and use this password to recover it.

The radio lock password is a bit trickier, it's at 0x3a4 and is 2 bytes. It's the 0000-9999 numeric password added with 0x4000.

Tuning length

These two bytes are the length of the tuning block. Typically 0x0280

Tuning Checksum

This is a byte which is modified to make the Checksum(8) of the tuning block 0x5A

Feature Length

These two bytes are the length of the feature block. Typically 0x0080

Block Header

This is the block header for the FDB. This is a recurring format for storing data throughout the codeplug

In this case it's typically 0x805201

This is a magic number of 0x80 a length of 52 and a repeat of the length of 01.

In this case it would start at 0x285 and go to 0x2D7 (the checksum correction byte). Note the 3 bytes of the Block Header are not counted, but are included in the checksum calculation.

Serial Number

These are 10 bytes of the serial number. You can make it whatever you want or keep it blank with spaces (0x20) to allow you to set it in tuner.

Model Number

These 16 bytes are the model number. This must match exactly if you want to use the CPS to program the same CP into multiple radios (along with the other FDB blocks).

Codeplug Version

The version of the Code plug 2 bytes, Major.Minor in BCD format

Note that this determines the length of block for FDB2 as follows. If this is not set correctly, it will not work. This also has effected the N control head,

This also has effected the N control head on a 220 radio. I was unable to get the N head to work at all with a FDB 2 length of 14 and a version of 11. the version needed to be changed to 3.2 and FDB2 to a 9 long one. It would then work.

Programing Source

1 Byte that shows the source of original programing

  • 0x0 - Factory
  • 0x1 - Depot
  • 0x2 - CPS

Programing Date

6 bytes showing the original programing date BCD format

Example = 0x1984 06 25 2344

  • 2 bytes year - 1984
  • 1 byte month - 06
  • 1 byte day - 25
  • 1 byte hours - 23
  • 1 byte minutes - 44

Channel Step

1 byte giving the channel step

  • 0x0 - UNKNOWN - only used on VHF Low Band
  • 0x1 - 12.5/20/25 KHz - Used on VHF only
  • 0x2 - UNKNOWN - used on UHF R1, R2 only
  • 0x3 - UNKNOWN - used on 800 MHz Only
  • 0x5 - 12.5 KHz only - used on 200 MHz only
  • 0x6 - UNKNOWN - Used on 700 MHz Only

Base Frequency

2 Bytes

Base frequency in hex expressed as the following formula:

Value * 25000 = Base Frequency in MHz

  • 0x320 - 800d - 20 MHz - VHF Low Band
  • 0x1080 - 4120d - 103 MHZ - VHF and 200 MHz
  • 0x32C8 - 13000d - 325 MHz - 330 MHz
  • 0x3A98 - 15000d - 375 MHz - UHF R1/R2
  • 0x6D88 - 28040d - 701 MHz - 700 MHz
  • 0x7D28 - 32040d - 801 MHz - 800 MHz

Low Frequency

2 bytes - Low Frequency of tuning

Value = (Low Frequency in MHz - Base Frequency in MHz) * 1000 / 5

Example Low at 200 MHz - 0x5848 = 22,600d

22,600/200 = 116 MHz + 103 base = 216 MHz

High Frequency

2 bytes - High Frequency of tuning

Calculated same as Low Frequency

Code Plug Part Number

16 Bytes of the code plug part number No idea what it's used for


16 bytes The TANAPA is a configuration code of the hardware in the radio. Model numbers can vary but the TANAPA can be close or the same. Not sure what TANAPA stands for.


Mobile Power Settings 0x2CF and 0x2D0 are low and high power settings. These are the fixed settings in the radio, not what you can adjust them to in CPS.

All HT's have this set to 0 in both. HT's don't have an info screen in CPS showing the power, that tab is not there for HT's

The setting is not linear. Below is what I've found in the default code plugs. Note the series here is the CDM (25) or the CM (50). Tested means it's not a number that appears in the default codeplugs, but what I got. Power is in watts displayed in the CPS info screen. I don't have this for all the values here.

Looks to be a bit mask. Changing from 0xA1 to 0x81 (toggle bit 5) changed an HT to a mobile. On the mobile, squelch adjustment went away, along with radio password. The buttons changed to be Mobile config.

Bit 5 on makes a mobile

changes in radio configuration

  • Auto power mode and radio-radio cloning, and hook defeats pl was lost.
  • Auto backlight and Tx Low battery LED were removed. Mobile backlight intensity was added.
  • TX low battery alert an wrap-around were lost.
  • Gained revert scan and hook
  • monitor sticky permanent alert was removed
  • control head mic was gained
  • default display stayed the same (this was a 4 line radio)
  • Lost radio lock password
  • TX Power, aux control, accessory pins and accessory config tabs gained.

controls and menus

  • conventional buttons changed to mobile
  • Utilities menu lost squelch, light disable, when available and radio lock.

conventional personality

  • advanced tab gained tx only personality
  • new tab "data revert"


  • mdc system config gained remote monitor tab


Not sure what this does, but I encountered a UHF R1 HT model H25RDH9DP5, that was 0xCC78 and it would not load the codeplug from a H25RDH9DP9 HT with everything in the FDB being the same other than the source CP was 0xCE79.

I tried changing each byte independently and CPS still would not allow the CP to be written to the HT. Only with both flipped to the proper 0xCE79 of the source radio would CPS write the unit.

Any more information would be helpful


Unknown, but appears to have something to do with features on a bitmask basis changed from 0xFF to 0xCF and lost remote monitor option in the radio call sub menu.

0x2E1 - FPP

This has more features on a bit mask basis.

Lower nibble known options

Bit 3 is FPP, unsure about the other bits.
5 - 0101 - FPP
D - 1101 - FPP
B - 1011 - No FPP
9 - 1001 - no FPP
8 - 1000 - No FPP 
4 - 0100 - No FPP ? - maybe a fluke? - only on 65 and 50 series radios have this bit set.
1 - 0001 - No FPP
0 - 0000 - No FPP

Note that enabling FPP is possible in the mobile and HT1250 (even 750) radios. It will show up in the CPS, allow you to add it to the menu and everything, but it won't work. Edit mode also needs to be enabled on that channel and you need the red battery or hacked firmware. If anyone has Ideas for the CDM, let me know.


Unsure what this is, but when opening an srecord and saving it again, CPS changed this from from 0x30 to 0x10 (and low power from 0x16 to 0x19).

Programing block

This now has it's own page

The programing block is the next block after the tuning and FDB blocks, typically starting at 0x300.


The radio is basically impossible to brick, but the Motorola upgrade tools are notorious for fucking up and leaving you with a dead radio. What's worse, is the official Motorola upgrader has no way to restart a failed upgrade. The Motorola tool must be able to read the code plug first, if it can't, it won't upgrade it. Motorola did this to prevent you from flashing radios to different models (MDC to 5 tone, etc), and the official tool installs a new default codeplug, they wanted to keep you from doing all the fun stuff we can now do in the feature database, by flashing a different default code plug on it.

Why can't I brick the radio?

Easy, the uP they use, a 68hc11, has a boot strap mode. What the CPU looks for at this point in bootstrap mode, is serial data loaded via XMODEM. In this 256 bytes of data, you load a program that can get the cpu going. Motorola loads the initial xmodem helper in bootstrap mode, then it loads a flash helper which is larger. This flash helper will write the flash chip on the radio. This is not a "bootloader" or anything like that, it's built into the CPU, and is well documented in the CPU datasheet.

Also side note, the cpu once programmed doesn't have a checksum on the firmware. The flash is memory mapped, and at boot the radio goes to 0xFFFE, reads 2 bytes as a pointer, then jumps there and starts running code. It's simple, but there's no checksum, so you can edit anything in there and not need to run a checksum.

Well I was fucking in the codeplug and wrote bytes it does not understand

This can get the radio stuck in a boot loop, or look similar to the firmware being corrupted.

No fear, just short out the SPI lines on the serial codeplug chip and boot it, then you should get "EEPROM CS ERROR" and can reprogram the backup codeplug (you did make a backup, right :)

Recovering a flash dead radio

Assuming your radio is truly flash dead, you'll need to reprogram this using the US waris kit. This will allow you to load any firmware on any radio. Simply select the right firmware file and flash it.

Note if using a real Motorola rib, don't go faster than 9600 BPS (20-30 min at this speed is normal)

Once the firmware is loaded, the radio may bitch with CS ERROR or something. This is good, it means you have a working OS on the radio, and you need to load the codeplug now that matches the radio.

Firmware files

These are text files of the binary firmware in S-record format. The only difference is the header must be removed. The file name must be *.0 as well, and it cannot be loaded via a network filesystem path.

Binary Codeplugs

These codeplugs are binary and have been edited for no serial number, 255 channels, 25-20-12.5 KHz deviation and signaling. Note when writing them using the CP tool you need to write 0x280-0x2ff. If you write the entire codeplug, you'll fuck up your radio. If you fuck it up, rewite your backup (you do have a backup, right?).
