I have an older Radius radio,16 channel......I want to be able to use it with the telephone mic......are these radios all setup,do ya just plug in the phone mic and away ya go........or is there a special program needed....I wamt to be able to use it in the bush for work as we have no cell service out there......thanks for any help,I know nothing about these radios at all..are they any good...was also looking at a used MCX600 on Ebay,not sure what is good or bad

You can't just plug in a DTMF mic and get phone service.

But most radius mobiles will accept the proper touch-tone mic and be able to send DTMF tones with no modifications.

Is that what you were asking?

Yep,that's what i wanted to know.....I know of a few guys that have the telephone mic on their radios...they say the reception and service is great if you are in a bind.......
I was looking at a GM300 on ebay,the seller told me ya just plug in the telephone mic and away ya go....I thought that it had to be set up or programmed for it.....

Well it has to be programmed to work on the system you are on, but that has nothing to do with the dtmf mic.
