As one who's always trying to figure out IF something can be done, I was thinking today..
What we don't have yet is an app or something that enables use of a CB radio.. Since I do ALOT of motoring, in the past I've always kept a CB in my truck to 'watch' for smokies and problems on the road.
The big downer for me was I couldn't listen to the music AND the CB at the same time..
So, I figure (while I haven't looked) there are probably some radios out there that can be controlled with a serial port.
Add that to the fact that the Empeg has AUX in, and voila! an app:
Application runs in the background on the empeg, and 'listens' to the Aux port. When the CB's squeltch lets a signal thru, the program auto-switches from the player to the Aux-In, until the squeltch goes away, then resumes the player. (Could take that one step further, with some type of serial connection, do scanning, looking for good channels..)

Remember, I'm not asking is it's PRACTICAL, just DOable.

The only I'm-Not-Sure-About points would be the 'listening' to the Aux port while the player is running. Is that even possible? (Accessing a different audio channel not selected.)

Am I insane? Did I pick something that is practically impossible?

Me, conjouring up different ways to just USE my Empeg.
