So you get pulled over by the H.T.P in Saskatchewan. You want to here everything they are saying about you? The officer has a wireless mike on him so he can record everything. I found The audio TX is on channel #7 184.3500 MHz analogue. If there is an RSI set up I will park as close as possible and listen in on it. Just scan the VHF/UHF T.V. bands to hear the action in your area.
