You need to be more clear in your verbiage.
What do you mean by "radio"?
You cannot use a scanner as a transciever.
You can use a scanner as a receiver (that's it's designed purpose).
What are you trying to receive? I have a Uniden BC-250D. Good scanner, but my main gripe is that I can't set the modulation modes on it. E.G., 28 MHz will always be FM, despite the fact that most amateurs on that frequency are using AM or SSB.
My handheld scanner has a headphone jack that I can use to drive a powered speaker.
