A channels.conf file is built from an initial tuning data file

The following method is fairly simple and always works. You should never have to go through this with current versions of the drivers and utilities.
channels.conf, and replace the long number after the first colon with the ``Mhz-number'' gleaned from the information menu multiplied by a million.
FEC_, so becomes
