  MaxTrac VHF, UHF,
and 800 MHz
Model Information

The following information was obtained from the Motorola MaxTrac Detailed Service Manual, "No Longer Available" (NLA). Some of the data may not agree with capabilities of the programming software. Note that this information pertains ONLY to the VHF, UHF, and 800 MHz MaxTrac models. Information on the 900 MHz radios can be found in this article, 900 MHz radio models by Repeater-Builder staff.

Additional information on MaxTrac logic and RF boards, plus firmware revisions, can be found in this article, An Introduction to the MaxTrac or Radius M100 / M214 / M216 Firmware, Logic Boards and RF boards by Neil WB0EMU.

GENERAL NOTES:

Generic Model Number Scheme:

The 12-character model number for conventional radios follows a reasonably uniform format, shown below in two tables:

First Seven Characters
DPower Watts Band MHzSeries
  0: 2 1: 29.7-50 AHA5: trunking
  3: 10-25 3: 136-174 MGA9: conventional
  4: 30-50 4: 403-470 MJA1: conventional
  5: 60 5: 806-870 MJA7: conventional
      MJA9: conventional
      MQA5: trunking
      MQA7: trunking
      MWA5: trunking
NOTE: I suspect that the MGA9 series is supposed to be MJA9.

As with most Motorola model numbers, you can NOT tell the band split (29.7-35, 35-42, 42-50, 136-164, 146-174, 403-430, 449-470) by information in the model number. You must open the radio and look up the RF board number.

Second Five Characters
ChansControl Head RevisionK
3: 2 04: 2ch A: earliest  
7: 6 A3: 6ch B: earlier  
D: 16 A4: 6ch trunking C: later  
J: 32 A5: 16/32ch D: latest  
  A6: 16/32ch trunking    
  B1: 2ch 1/1/0    
  B3: 2ch 2/1/0    
  B4: 2ch 1/1/1 T/A    
  B5: 2ch 2/2/0    
  B6: 6ch 6/6/2 T/A    
  B7: 10ch 10/10/10 T/A    
  C0: 16ch trunking    
  C3: 8/16ch 8/8/8 T/A    
  C5: 8/16ch 8/8/8 T/A    
  C6: 16ch trunking    
  C7: 10ch 10/10/10    
NOTE: In the Control Head column, the three digits separated by slashes (1/1/0, 8/8/8, etc.) are the number of trunking systems, the number of trunking sub-fleets, and the number of conventional channels that the radio is capable of, in that order. Also, T/A stands for Talk-Around.
