I don't wheather it's my scanner or my antenna or both.
I live in Santa Rosa, CA. and I thought the CHP was on the Emerald channel...42.88 for base. Now, for some reason I can't pick them up at all. Have they changed or is it my whimpy telescopic antenna?

Don't forget that CHP reuses frequencies around the state, so you have to listen to make sure it's the right area, or have the PL tones in place, to make sure it's the right area.

From Sac, I have the 42.88 PL 131.8, and not getting any activity. Could just be the distance, though.

Most likely your reception is due to an inadequate antenna or your geographic location.
Sometimes radio channels fall under maintenance and they use an alternate channel such as CHP Blue.

Check surrounding CHP freqs and try moving to other geographic locations.
