Motorola has some new business band hand helds out.

8 channel vhf @ 2watts

8 channel uhf @ 4watts

16 channel uhf @ 4watts

Below are freqs avail for them and also the default channels in them.
They must be programmed with software to change settings from default.

Notes:
• (†) Bandwidth for frequencies 10, 22 and 27 are not selectable and different from XTN. You might
notice the communication quality differences when using these frequencies to interoperate with XTN
radios.


• (*) Due to FCC regulations these frequencies (six in total) are different from the previous Motorola
Legacy Series radios. This means that if you select the RDX radio in one of these frequencies the
radio will not inter-operate with an XTN radio. In order for a RDX radio to inter-operate with an XTN
radio, make sure you choose any of the frequencies (21 in total) that are common for both radios.

I believe you can get the programming software for free if you register. Of course you'll have to take out a second mortgage for the programming cable, but free software is good.

Motorola giving free software?

Ill believe it when pigs fly! :shock:

Go to motorola.com/RDX, click "Skip intro" then "Resouces" then "Customer Programming Software". It's a 7.2 MB zip file that won't download unless you disable your popup blocker. Soooo many poor design choices on that site. And here's the USB cable via Amazon, $50. Looks like a standard USB cable.

Damn it! Flying bastard just took off my chimney!


I guess I should believe it. They have provided free cell phone software so this shouldnt surprise me.

:mrgreen:

And I'm sure that the APX software will be free too......
