• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

How to functionally test a Motorola Trunking radio?

Hello, all.
I'm on the RF bench again and it's been 10 years since I've had to functionally test radios. I'm hoping to get some feedback on the steps needed to functionally test a radio that comes across my bench that is trunked.

We have many MTX8250 handhelds that come in for PM checks. I have no problems getting these into test mode and testing the Tx/Rx side (anaolg).

What if I want to test the trunking side? I just had the Senior Tech blast through the process at the speed of light and he lost me.

I'm using a R-2670 FDMA Digital Communications Analyzer. My goal is to document what information I need to get and what settings I need to get into on my analyzer.

Can we get some people to chime in on where to start?

Get the operator manual for the Communications Service monitor. It will tell you how to setup the monitor to act like a trunked system fixed end. It will also give you the setups to test the power out, receiver sensitivity, frequency tolerance, and modulation level along with a few other tests. I would guess that your shop has a standard PM service form that identifies most of these measurements. Our form also includes the SN of the Monitor and the latest calibration date.

Thank you. I'll start with that. and no, the shop has little to no documentation.
