Re: VMWare and programming

Interesting note, but you can actually program legacy radios like the Jedi and Astro series all the way up to Windows 10. It just has to be a 32-bit version of whatever OS you want to use. The CPS serial implementation breaks in 64-bit windows for whatever reason.

Re: MTS2000 programming

You need to be using 32 bit windows and preferably a hardware serial port. The serial implementation Moto uses for older CPS versions is not compatible with 64 bit OS's and while the application will run serial comms won't.

Re: APX7000 out of band question

No APX radio can go out of band. The software can be hex edited to accept frequencies outside the rated bandsplits like other CPS versions, but the radio firmware will reject any OOB frequency that is programmed in to it.

LMR240 ultraflex wouldn't be a bad idea. If you wanted lower loss you could bump up to LMR400 UF. 240 is the size of RG8x and 400 is the size of RG8.

If I wanted portability and low loss I'd put my money with LMR240 UF. At 50' you'd have 3dB of loss on 440. LMR400UF would be ~1.5dB loss at 440.
