Simulcast, it seems, is always a consideration. But for the OKWIN P25
system, the site in the OP's county (Wagoner) is at Coweta, and is not simulcast.
For the
Broken Arrow Phase II system, Site 1 (Broken Arrow) is simulcast, but only one of the transmit sites is in Wagoner County, and is some distance away from the OP's city. The other three sites of the simulcast are in Tulsa County, and even farther away from the OP. I suspect that at that distance, he might not have an issue. There is also a specific site in Wagoner (
21-15), and that is not a simulcast. The OP should have no trouble at all on that one.
I would definitely agree with you that, at some point, the Phase I (Mode
D) talkgroups will transition to Phase II. How long in the future that might be, I have no idea. Someone in the Oklahoma forum might have more info, but in any event, I would lean toward a Phase II capable scanner if at all possible, even though it is not required just yet.
Since simulcast does not appear to be an issue (at least when dealing with OKWIN in his county, and using the site in Wagoner itself for the Broken Arrow system), the OP does have a number of options. Disregarding simulcast, the older, and now discontinued, Whistler database scanners (WS1080, -1088, -1095, & -1098) should work at his location, as would the newer TRX-1 or TRX-2, along with Uniden's HP-2, 325P2, & 996P2. Probably the least expensive would be a good condition, previously owned, Whistler database scanner (the discontinued models).
