I just got a pro-107 and would like to say that I love this scanner. A previous thread on hear said that it is so easy to use a child could program it and I would have to agree that this is the easiest scanner I have ever had to program. I was wondering if anyone out there owns this scanner and uses an amplifier or preamp that works well. I am using it both with an indoor and outdoor antenna (antennacraft). Either kind of amp I would be interested in. Much thanks for any response.
