Love the Pro-106
I've had the 106 for awhile now and really love it. The downside is that there are so many bells and whistles, sometimes its easy to get lost. My top recommendation is to get the programming cable, software (I use Win500) and subscribe to Radio Reference to load frequencies in the scanner -this makes setting up and maintaining this great radio much simpler. Once you get your feet wet filling it with your local frequencies, you can start to fiddle with the finer settings in the software, like setting up the led lights (I use red for fire, blue for police, etc), backlight and other features.
Overall, one of my favorite scanners (I have over 20!). Good sensitivity (although my old Pro-96 seems slightly better at picking up digital signals) and well constructed.
Hope that helps - enjoy! You get alot more out of this (and other radios) when you read the various postings on RR - there are alot of nice tips I have picked up that have enhanced my enjoyment of the radio.
Regards,
Bob
