Actually you can hear other troops from the troop you live in. I'll explain...
When a Troop A trooper travels to say, Troop C. If that trooper still has his radio on Troop A, then the tower his radio is associated with (the one he is closest to) will broadcast all the audio that he is hearing over the air (ie, your scanner can pick it up.) That goes for any talkgroup on AWIN. ADEM, State Health, Counties, etc. So if you have a Washington County unit on AWIN, and he drives to say Texarkana and leaves his radio on Washington County the entire trip, he can listen to his home area traffic from where ever he is in the state and anyone using a scanner to monitor the tower he is on, will also hear his traffic.
That is why you heard Troop A from where you live. Likely a unit (anyone with an AWIN radio) had Troop A channel tuned in and you were hearing the traffic.
