Yes the VHF channels are still there, but there has been a lot of channel swapping so your channel 6 or what ever may be some where else (IE a different channel).
The previous post has a good link, but...fill in all the blanks. I did it just using the zip and ended up with a lot of wrong distances. Channel 19 from Mt Pleasant was over 40 miles instead of less than 20. It listed some channels as being fringe or out of range when they were only 40 miles away. When I put my address in it listed them correctly.
