• Instructions for modifying a CDM1250 to 222MHz - From W5TXR.net Thanks Mark!!

This lays out the basic steps for changing band edge information in a WARIS radio. Useful information for other haX0ring inside these WARIS units.

LCD Display Repair

One of my HT1550 XLS radios had missing horizontal and vertical lines on the LCD dot matrix display. I successfully repaired the display and documented it at the page below:

Flashing one of these units

I have the flash mod done to my cable (switch from Gnd to BootCtl) but the Waris Flashtool still says Radio not in Bootstrap or some crap like that. The radio definitely acts different with the switch in the flash position and boots up with no beep and a blank display so I know it is doing something. Anybody got any ideas email me at jonathan (a) n4vx . net

Converting HT750 Lowband 35-50MHZ to 6M

Huge thanks to Bryan W9CR for publishing all his amazing work in diving into these radios. Most of this information is a mimeograph of his work.

• Project Beginnings

I was given (thanks AF4AY) a HT750 Lowband R2 (35-50MHz/PMUB1026A/AAH25CEC9AA3AN) that had a corrupt codeplug and would not read or write with CPS. I also had a HT1250 Lowband R2 (from eBay) that was purchased as a parts unit and probably has a bad AT49LV001 flash IC and wasn't worth the trouble repairing. I used the functional HT750 board and the HT1250 limited keypad and display housing to make a good unit that only had a EEPROM CS ERROR problem. Easy fix!!
I played around with several TANAPAs and found PMUB1023A (xxH25CEH9AA6xx) to be what I wanted and used US Waris CodeplugTool to blast from 0x000h-0x2FFh into the target Franken-Radio. I now had a functional HT1250 Limited Keypad Lowband R2 Radio!! The problem is, NCSHP is no longer on 42MHz and I have no other use for radios in this frequency range. Time to make this radio useful again!!

• Moving up the street 5MHz

Following W9CR's fantastic wiki site and YouTube videos on the Waris Radios, I was able to dig into the new Franken-Radio to fiddle with the band limits, tuning piers and features to make this radio identify as a ham radio.

Waris Codeplug Band Limit Maths

• Frequencies are determined by a Base hex value a Frequency hex value and some math.
  • The base value lies in the codeplug at 0x02AD-0x02AE. In this lowband radio the value is 20MHz and the maths to determine the hex value is 03 20 for a value of 20MHz
  • Lower Band Limit @ Ox2AF-0x2B0 Change the old 35MHz 0B B8 to 40MHz 0F A0
    
  • Upper Band Limit @ 0x2B1-0x2b2 Change the old 50MHz 17 70 to 55MHz 1B 58
  • Tuning Piers:

Freq. Before	Value Before	Freq. After	Value After
34.975	0B B3	39.975	0F 9B
37.525	0D B1	42.525	11 99
40.025	0F A5	45.025	13 8D
42.525	11 99	47.525	15 81
45.025	13 8D	50.025	17 75
47.525	15 81	52.525	19 69
50.025	17 75	55.025	1B 5D

• • Change your checksum bits to make your FDB1(0x282-0x2D7), FDB2(0x2D8-0x2E4???) and Overall (0x280-0x2FF) Checksum-8 to be 5A
  • This moved the radio up 5000kc to now believe it was born as a 40-55MHz radio and be able to hold tuning values within that range. It reads and writes from stock CPS as if Mother M made it this way. You now have a 6M Motorola HT!!!

• Settle Down Nelly

The alignment was horrendous at this new range and I probably should have read the alignment block before starting this venture but I have access to a service monitor and can get this thing back in the ballpark so I'm not too worried. It has about 8kc of deviation at normal speech levels so that is my first order of business. Also this is a ham radio and not going to be used by the USSS so I really don't care if it is a little wack. Hey at least it isn't a Baowank.
