Portland Metro areea: 155.43 and 155.19 still in use by?

I believe these used to be Clackamas County Sheriff's frequencies. And I also know that years prior, 155.19 used to be the main Portland Police west side frequency. I noticed that both of these freqs are still in use - apparently by the same agency - and that they're referred to as "Net 1" and "Net 2" respectively. Net 2 (155.19) seems to be used for records checks and similar business, whereas Net 1 seems to be dispatch related.

Are these freqs still used by Clackamas County SO? And if so, why are the units heard on them still using these VHF channels instead of the newer WashCo/ClackCo/Newberg 800 MHz Motorola trunk system?

I'm sure there's an easy answer for my questions but I've been out of public service radio monitoring for a while so I've not followed many dynamical developments in the area.

TIA

The longish short answer is that the design and engineering of the 800MHz system does not penetrate well into the more rural parts of Clackamas County, and also because other counties and cities that could provide mutual aid assistance (for example) (Wasco, Hood River, Marion, Jefferson counties and associated cities) are still on VHF. Those two frequencies are tied into the 800MHz system, however, providing a bidirectional communications link between both bands.

155.760 is also tied to CCSO Law 3 in late afternoon 3pm to 3am its used as records, but though out day before 3pm you hear Unit to Unit traffic.

That explains it. Thanks
