Scanner-radios picking the right scanner - There was a time that scanning was easy. There were no trunked radio links and no digital radios. There was no encryption with frequency hopping to drivge us scanner radio-operators nuts. And there were no laws at one time telling us what we can scan and what we can not scan. Fortunately even with the above scanning is still a fun hobby.
