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:

• 800 MHz radios can receive 851-870 MHz and transmit 806-825 MHz. Those with talk-around can also transmit 851-870 MHz.
• All radios support PL, DPL, and CSQ operation for receive and transmit.
• The 11th character of the model numbers, the revision, is shown here as an underscore (_). This is how the model number appears in RSS.

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
D	Power Watts	Band MHz	Series
	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

Second Five Characters
Chans	Control Head	Revision	K
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.

Discrete Model Numbers:

General notes for the tables below:

• Init: what model series the radio is initialized with.
• Chn: number of conventional channels the stock radio is capable of. Follows the same format as found in the Control Head column in the table above.
• T/A: Talk-Around - Yes or No.
• LB: logic board number. All boards have an HLN prefix and an A or B suffix.
• In the LB column, * indicates HLN5173 or HLN9313 EPROM logic board.
• Logic board HLN9313 has a 16-pin accessory jack. All others have 5-pin jacks.
• Logic board HLN9123 has firmware permanently burned into the CPU. All other boards have replaceable firmware contained in a PROM or an EPROM.

NOTE: The D51MGA93A5_K model number should probably be D51MJA9JA5_K to agree with all the other MaxTrac models.
