[digitalradio] frequencies for ROS

[Edward]

i will not elaborate on the on going debate of ss. just do a google seach on 
the theory of spread spectrum. that should anwser all ur questions. i've been a 
two way radio repair tech and system installer for 49 yrs so i know what ss is. 
my question is this: what frequencies are being used, in the us or over the 
pond, for ROS. i would like to monitor some ROS sigs.
thanks all
