I didnt realize David did both of the Norcal feeds on this site. I know the creator of this site took the feed off the board for the one feed but the other Norcal feeds still listed on here but showing it as being down!
The remaining Norcal feed is run by somebody else. It hasn't been up for a while but I will check in with the maintainer. He goes into periods of inactivity and needs his scanner for other things.
Remember, not all of the feeds can be up 24/7, or even often. It all depends on the person sending the feed.
