The biggest expense was not the switch to digital, but the move
to a new frequency. TV transmitters are built to operate on a single
frequency. To switch channels, you have to replace it.

That doesn't sound right, especially if the change in frequency as
small. Shouldn't it be something like the crystals used in old CB
radios?
