Update: The B150 headset has been replaced by the B250.
I'll show you how to build a bluetooth audio interface to your radio. This gives you hands free operation and allows you to move around the hamshack. The range is typically line of sight, about 20-30 feet depending on how many walls you are having to transmit through. This interface gives you a lot of freedom in the shack to move around, surf, solder, work on projects while on the radio.
This uses a Jabra A-210 interface. This interface is made to plug into a cellphone's headset connector to allow a bluetooth headset to work with the cellphone. It is an easy project to interface to your radio's microphone and headphone connector.
We have also found the VXI BlueParrott B150 bluetooth headset to provide very good transmit audio.
Frank, K7SFN, has documented this interface on his webpage.
