I recently bought a 125AT and so far it has worked fairly well. The issue I am having is when I hear the fire department (behind my house) get dispatched, I hear the dispatch tone and sometimes I can hear what the dispatcher is saying in the station (ie, what the nature of the call is) and sometimes I only hear the dispatch tone then a minute later I can hear the dispatcher say the ambulance is responding to the address and I can't hear what the nature of the call is. Is this blocked? Is it my scanner? Is it the signal? Some insight would be appreciated. Thanks.
