Spar is that the short of thing ie scannor you could use would I have to bye a reciver to fit on the tail is that 173 ,Iam loseing it here ,
all you would need is a transmitter the frequency coverage from 100 kHz through 1299.99995 MHz so you most probably could pick up anything 173, 216, 433, and find out when your neighbors are going to get raided by the police
