Software is free and easily found on the net. Version 4.0 runs fine on a WinXP computer. Cables are cheap; serial is more reliable if the pc has a serial port.

You are looking for 1225LS_RSS_V3.0.zip. I have a copy of it which is about 5 meg in size. It's designed to run on WinXP or Win95. For best results, it should be run on an older machine which has a true serial port (COM1). If you open the radio and it has an LTR Passport accessory board made by Scholar-Johnson, you can simply remove the board and the radio will revert to a standard M1225 which can be programmed with the version 4.0 1225 HVN9054 software. The Scholar-Johnson board is desirable by some hobby folks. I sold one on Ebay in less than a week.

Better to get a 3”x3” square of helicopter tape and put that down on the roof first. It won’t let the mag mount scratch the paint and is easily removed when desired.

There’s a hidden compartment under the driver’s seat which should be completely empty. The battery is in an identical compartment under the passenger’s seat.

IIRC, this site downloads an extract from the FCC database once a week so it may be a few days before the site recognizes your license.

There’s several listed on ebay right now.

My Motorola Commercial and Professional Series radios all cover 438 to 470 Mhz covering 70 cm ham, most UHF LMR, and GMRS bands, no mods or hacks required. Some of the higher capability Commercial Series units can be programmed for FPP selectable PL or DCS.

I found a refurbished Panasonic Toughbook with a new install of XP for $125 on Ebay a couple of years ago. It has a true COM 1 serial port and works perfectly for Waris, Commercial, M1225, and many Radius models plus older Vertex, Icom and more.

One that’s not currently in use if you want to find a quiet channel to communicate with friends and/or family. You have to do some monitoring to determine this if you’re looking to reach out to chat with others, you’ll have listen to determine which channel they are using for chat. The answer is specific to your immediate area so any info from those of us not in your backyard is not relevant or reliable.

So back to your original question… Yes, it appears possible to add more channels. Are you asking how to do it or do you already know how and have the necessary cable and software?

UHF-1 403-470 Mhz 1-25 watts 1 line display, standard keypad Conventional & PassPort capable 128 conventional channels

???? The model number is much longer than that. You’ll find it on a sticker on the bottom of the radio.

Depends on the exact model. Some are limited to 16 conventional channels while others can do up to 160 conventional channels. Post your exact model number and will look it up for you.

Rich posted elsewhere that the FCC site is having issues. Until that is resolved, MyGMRS.com can not update the member files. Rich made it clear the he can not manually override so you’ll just have to sit tight until the FCC fixes the problem.
