I was talking to a friend that is looking for an SWR meter that you can use to get the swr's on the antenna set.  He has one that he is using now with the radio and he doesn't want to jeep getting in and out of cars to do this.  I told him that I didn't know of any meter that would do that but I would ask around.  We are putting cb radios in the police cars as a backup to our 800 MHZ system.  Right after the storm  (katrina) last year we lost the ability to communicate for a few days.  Not totally reliable but better than nothing.
