[BC] Call Letters

[Dana Puopolo]

ABC wound up on channel 7 because their Director of Engineering at the time
believed that high band VHF was superior to low band because of the power you
could run (316 kW vs 50 kW) and the fact that it's less affected by skip.
History apparently proved him right.

same. CBS O&Os are on 2, ABC on 7 and NBC on 4.
