radio uses
Good morning jwko, I send this advice with the best of intentions, and in no way do I mean any criticism. The radio you purchased has an incredible ability, you really should spend some time working with it. An entire world exists to listen to beyond repetitive traffic stops. You have the ability to initiate a 'Limit Search' from 25.000 Mhz up to 1300.0000 Mhz, and anywhere in between.
There are bands that hold strange sounds, and people hijacking bands from the government, speaking foreign languages... I have spent forty years scanning bands and still learn something new every day when I pick up something I have never heard before. The radio you purchased is manufactured to receive systems that that no "scanner" ever has. There is another brand that will allow you to choose modes of transmission, or KHz. steps to monitor.
My point is, experiment, and experiment some more. You might just get hooked on finding something unknown and letting everyone else know that you found something pretty cool. Give it a chance, and search. Good luck to you, and take care.
