M1225 how to test

[Garfield1111]

Motorola radius, M1225. I don’t have any antennas, but I do have microphones I bought what is supposed to be a functional frequency counter off of eBay and when I key the microphone, nothing happens I stuck a little piece of wire in the antenna port still nothing on frequency counter. Trying to figure out what frequency this is transmitting on and then also find out what kind of antenna I need to put on my truck. Also, it seems to power up like what I would think is normal and no matter what button I push it seems to only go from channel 1 to channel 2. Thanks for any help.

The model number shows it as VHF 150-174 MHz.
It’s possible that the radio is programmed for receive only. In any case, keying the mic without an antenna, or at least a dummy load is a good way to ruin it.
Your best option is to obtain the M1225 CPS and buy a programming cable to read the radio. The 4.0 version is Windows compatible and will run on Windows 7 with a 32 bit machine. Buy an FTDI ribless programming cable from Bluemax49er. The cheap ones on Amazon or EBay are hit or miss sometimes.

It will also run on Windows 10 32 bit such as LTSC 2019.

Can someone tell me what part number the antenna would be? I have more than one of these radios, so I’m tempted to just get the proper antennas and see if they talk to each other..

Proper antenna will depend on what frequency you are using and what sort of installation.

Also, keep in mind that you do need an FCC license to transmit with these radios. You don't know what frequency they are on, and you could possibly interfere with other legit users (even if you can't hear them). There are no "free" frequencies in the VHF band that you can use these radios on.

There is no specific part number for the antenna. You need a VHF antenna with a mini UHF connector.
Also, unless you have a license for the frequency those radios operate on, you shouldn’t use them like CB radios.

Sounds like I need to focus on how to get the software. I’m assuming that a Motorola dealer is not going to do this for a reasonable fee.

No, a dealer (if they still have that software) would charge more to program it than the radio is worth.
The software is widely available for that model. A Google search should take you right to it. Until the rules of this site change, the exchange of CPS through RR is not allowed. However, the M1225 series has long been discontinued. It’s an easy find. Like low hanging fruit.
