A pro-163 will pick up TPD, TFD other Tulsa and surrounding agencies (Catoosa, Sand Springs, etc) that are on the OK DPS Tulsa site just fine - everything but EMSA and the SWAT team. No telling how LONG it will do so, though.
I think it's funny that the store closest to me sells the 197, but doesn't stock the 163. I walked in and told them I wanted to hear Owasso FD, Collinsville FD, Limestone VFD and Skywarn and they told me I HAD to have a $400 digital scanner. I then pulled out my 163 and showed them that I did not (Owasso FD was working a grass fire M/A with Collinsville, so there was plenty of traffic on both the 800MHz MOT system (Owasso) and the VHF Collinsville freq.
They were flabbergasted when I told them I bought the 163 at the 27th & Harvard store for $150 and wanted to know why they didn't stock it.
Then the older guy (1/2 my age, and I'm not old!) tried to tell me I'd need the 197 to hear Broken Arrow.
Clueless! but typical.
