Maxtrac 800

Rayjk110 · Post by **Rayjk110** » Thu Feb 09, 2006 2:55 pm

Hello all. I have 6 MaxTrac 800. Model Number: D35MQA5GB5BK. All have s/n's close together in the 438ARG1XXX Range. ANYways...I can read the radios just fine in Maxtrac Conventional RSS V5, but cannot read the frequencies at all in the codeplug. (Guessing I need a different RSS? Which RSS do I need for 800 MaxTracs?) Also, what I am trying to do with these is Monitor an 800 MHz Frequency (860.2625) and that's it, nothing elese. (Hoping this is possible. They are the 2-button head with Sys1 Sys2 Sub1 Sub2)

Thanks for any help.

Yes, the trunked Maxtrac radios have their own RSS...reading them with conventional RSS gives exactly what you've found. The part# your looking for is RVN4043N...latest version is 5.07.01

Not that it'll help you though...the 2 sub/sys models were trunking only...no conventional channels.

If I were to blank the board (already did that one 1, ive got 6 to mess with) and re-initalize it with a conventional pers., (assuming I could find one) would that work?

The nice thing about the Maxtrac is that after you blank the logic board, the conventional RSS will let you initialize the radio to your needs without requiring a matching codeplug file.

You will need to change the trunking firmware to conventional.

There is a lot of great Maxtrac conversion information on the repeater builder site.

What logic board do they have?

Well, I see a sticker on the inside of one of the units that says HLF4095B

Or, if that isn't it, on the other side under the sheild I see HLN5172A. There is a removable chip with (c) MOTOROLA 1990 HLN9260C Ver 52.08 on it as well.

OK, the 5172 is the expanded 5 pin board.
I have some with that setup that are 2ch. ( I think with the same eprom)
Ch 1 is trunking and ch2 is conventional.
So you may be able to do what you want with just trunking RSS.
(maxtracs.exe is the main file).
Or you can blank it, but you will need a conventional chip.

Ok. I tried reading with Trunking RSS and all I get is:

Error 5:
Serial Bus Error: Timeout
Comsult manual for list of error codes
and Possible Solutions

Go into setup F9, F3 and make sure your com port is set correctly.

Well, If I try to do that, then it wont let me move in the Configure screen because it says path does not exist.

ok. Well, I was able to read the radio. Great. Now, when I hit "f2" when viewing the codeplug for Trunking and Conv. Pers, I get:

OVERLAY EORROR DETECTED
PREMATURE END OF FILE
Function Will Not Be Executed
Error # 3 OverLay # 8

??

Sounds like you have some corrupt or missing files for the program.
You could send me the codeplug (and maxtracs.dbf file) and I can try it....

OH, and if you type in a correct path, or hit shift-tab you can step back to the com port, but I guess you have that working.

Ok, I'm able to see it now. For some reason the computer needed to idle for a while for me to access it. Now, how would I go about changing the actual frequencies? For some reason I can veiw them, but not change (Pressing TAB or ENTER will not highlight them....just skip them)

Changing the trunking freqs will not help you.
You will not be able to monitor a conventional freq unless you can delete a system, and set up a conventional mode.
I may be that it is set up for trunking only also, but I have seen the 5172 board do a conventional and a trunking.

Yea it says under the radio config: Max Trunking Pers: 2

and then Max Conventional Pers: 0

So when I go ahead and try to add a conventional pers, it says something like the max conv. pers are already in. (there are none already in, because the max is already 0, which is the max). SO...unless I can change the Max Conventional Pers #, then I'm not sure what to do.

try deleting all but one trunking personality

I don't think you're going to be able to add a conventional channel to those radios without re-initializing them to a different model or hacking the MDF file.

Model D35MQA5GB5BK is listed as a Privacy Plus 2 system, 2 subfleet, trunking only radio. Certainly the hardware supports other configurations. The firmware may as well. But the unmodified RSS won't let you add features that are not defined for that model.
