However looking on Kimmys the Birmingham shopwatch appears to be a semi duplex system so the control is on one frequency and the handhelds on another ie 442.0125 and 427.5125 which is why you are only hearing one side ( 441.025 and 426.525 are the frequencies for the retail crime ops)
in order to make sense of the conversations you will have to monitor both frequencies almost simultaneously and the easiest way to do that is to have two receivers
