If you haven't spent some time going through the batlabs site, I would suggest that you go there. http://www.batlabs.com and go to the radio section on mobiles and select the Maxtrac selection. Read everything there and if you don't already have it, download the Hex Edit file.

Your probably going to have to HEX edite (hack) the RSS to get you to the ham frequencies. You will need to change the band edge locations. Also keep in mind that once you hack the RSS, that will be the only RSS version that will be able to read that radio.

Before you modify your RSS, it would be a good idea to save a copy of the mdf file to a floppy. This way you can go back and restore the RSS if you need to in the future.

It probably would be a good idea to also make a copy of the radio code plug and put it onto a floppy. Again if you need to go back and restore or start over, you have the original code plug from the radio to work with. Don't use the backup location in the RSS for your storage location. It is too easy to mess up and write over it. Use the F2 selection to go to another archive location. Just enter the A: for the archive file location. To get back to normal, close the program and then restart it.

You should be able to program your out-of-band frequencies into the RF units directly with the Maxtrac RSS using the shift key trick explained on the Batlabs site if your RSS is new enough - otherwise you'll have to do as Jim says and hex-edit the necessary changes to the RSS.

Thanks for info, what newer version of Maxtrac RSS would I looking for "shift key trick"?

[xmo]

Versions up through five dot something do not recognize the shift key trick. Version R07.02.00a definitely does.

Ok, I hate MOther M RSS more and more

I picked up a couple of Desktracs......Some V and some U....trying to put them on ham band....RSS version I have for Desktrac is R3......I DONT have Maxtrac RSS so am I screwed??? I tried hacking the HEX code of the RSS I have and manually entered a 444 freq on xmit....it took it in the file...but then running the program causes it to lock up and freqs show 0.000 on both RCV and XMIT!!! SOOOO back to the original files....and everything is back to ......normal....which doesnt help me a bit! I have the GM300 RSS as well...is that the same as the Maxtrac????? What can I do to put these boxes down into the ham band?? The VHF is not a problem (right now) as they will go into 146......but if I want to program a 145 rptr pair, Im sunk......

HELP!!!!

Thanks in advance...(Damn, this made me think in DOS again!! I had to dig out my old PFM program which I got 20+ years ago....nice hex reader in it! BTW I did notice in one file, and I cant recall which one, there was a listing for LOW 1, 2, 3 VHF 1 2 and UHF 1 2...I assume setting the band limits....however only the last TWO HEX Pairs were different....this doesnt make sense as R1 is 449-470 and R2 is 470-512 right?? OR am I reading that wrong??? IF ANYONE can help it would be greatly appreciated....I knew I should have stuck with the Midland STIIs
