Hopefully you will get an answer from someone that lives in the area but I travel through that way quite a bit and it has been all digital for past couple of months.
EDIT: I did keep the analog/CTCSS info for Lincoln Co as well but only heard things on the digital end.
Hey there, i live just to the south of Lincoln County in the Wausau area, and AFIK they`re nearly full-time P25, however they do still run some limited analog traffic on the main Sheriff channel, but there is more P25 than analog on there now. Hope that halps . N9NRA
