Currently phase 1 but I have heard rumors that they will be switching to phase 2. Not sure how quick that will be as those rumors started a few years ago.
did you have a suggestion for just phase one?
The older Uniden 396XT & 996XT would handle Phase I only, and can be controlled with ProScan.
There is some PC control capability in the software packages that cover the Whistler WS1040 and WS1065. (That includes the previous models of the same scanner: PSR-500, PSR-600, Pro-106 and Pro-197. All of these were manufactured by GRE, which is no longer around). Whistler bought the rights to these scanners, and sells them as the WS1040 & WS1065. The Pro-651 & Pro-652 are the same scanners, manufactured by Whistler, but sold by RadioShack with the Shack's name on them.
I could be mistaken, but I don't believe you have the remote (PC) control features available with the Whistler database scanners (these all cover P25 Phase II as well as Phase I): WS1080, WS1088, WS1095, WS1098, TRX-1 & TRX-2.
Looking at your statewide system:
Oregon State Radio Project Trunking System Profile

That system is P25 Phase II. While it does not yet include your county, notes on it's database page indicate it is still being expanded to additional areas. Frankly, as the P25 Phase II systems become more & more prevalent, either for newly built systems, or as an upgrade to an existing system, I would suggest focusing on a Phase II capable scanner. Phase I might work for now, but at some point, it's likely to be upgraded to Phase II, or replaced with a newer Phase II system.
