You could, instead, put the channel number inside the [], like:

[CHANNEL 2]

I actually think that this makes the file better readable. Take a look
at this file, for example:
	isdb-t/br-Brazil

(that's basically the basic channeling used on NTSC, except that ISDB-T
 main carrier is not at the center of the channel, so the frequencies
 there have a shift when compared with the analog TV frequencies).

There, I opted to put a notes about the unused frequencies at the
header. This very same file is also used on other Countries in
South and Central America.
