Actually it gets quite rediculous when you consider DVB-T transmissions.
In Melbourne, channel 7 ("Channel Seven Melbourne Pty Ltd") transmits on
what is actually VHF channel 6. Channel 9 ("General Television
Corporation Pty Ltd") is on VHF channel 8, and "Network Ten (Melbourne)
Pty Ltd" is on channel 11. etc.

These stations do actually have callsigns, but they never use them.
Here's a list of all the stations using a single transmit site in Mt


You can see analog(video plus two audio licenses) and digital for each
at the site, for 7, 9 and 10. If you follow the license links you can
see that Ten's digital transmitter has the callsign ATV11, while their
analog is ATV10. Nine's digital is "GTV8".

I don't see any need to put that information into Myth though. Anything
unique should do as the callsign.
