I am operating on the vhf 151-159 range and I only use about 40 channels so that is more than enough. This is for fire use
Those views reflected here by me do not reflect those of my department.
I've used both, also.
Either radio would be fine.
I'd be willing to bet that for your use, 100 watts isn't necessary. The difference between 50 watts and 100 watts really doesn't add up to a whole lot. Anyway, before you spend the money on a 100 watt radio, check to see what the departments license says. No use running 100 watts if your agency is only licensed for 50.
We ran MCS2000's at work for a long time, both VHF and 800MHz. I wasn't a big fan.
I've got a bunch of CDM1250's at work. I've got CDM-750's, 1250's and 1550's for my own personal stuff.
If you don't need all the extra buttons, the CDM-1250 will work just fine. The non-trunking models will do 64 channels.
The CDM line was also EOL'd only recently, and the MCS2000's have been gone for a while. Based off that, it's likely you'd have better luck getting a CDM repaired or for finding replacement parts.
And since this is going in your personal truck, I wouldn't get hung up on the "public safety" versus "commercial" thing. The people listening on the other end won't be able to tell, and you are not going to beat up a radio so bad in your personal vehicle to really need one.
Either way, if you do install one of these radios, make sure you do the following:
Power directly off the battery and use the ignition switch lead if you need to.
Install the large Motorola external speaker. They really make the radios sound nice. The CDM's do OK without them, but they really sound better with the external speaker.
Make sure you get something in writing from the licensee. As an employee/volunteer for your department, you are not legally allowed to add radios to the license without the licensee's permission. Make sure you get something in writing, and make sure you get any frequencies for other departments approved in writing from the agency that holds the license.
