Your 706 should simply tune the CB in receive mode without ANY
modifications.

I have 27185 KHz [Channel 19] programmed into mine [706 MKIIg] and
monitor the interstate traffic as I drive along.

NO MODS NEEDED!!

I'm looking for a way to open up my 706 to 11 meters (a.k.a. Citizens Band)
because the local snow plowers in the area use that band and I work for
them. I've got my 706's mounted in my trucks and I'd rather not mount a CB
radio and another antenna in the trucks.
