Waris

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.

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).

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.

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, 2.0.2.5.

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.

HT1250LS+ 220 700MHz Service Manual

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 is the same, but it's got a 12KHz and then a 9 KHz filter at the second IF.

I've changed out some filters and found it works much better on the ham bands. You need to adjust the squelch for 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 $program to access the greyed out menus in tuner.

HT1250 Filters: 

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


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!).

Software mod

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.

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.

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.

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.

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.
