However, that station moved to VHF channel 12 a few years after taking to the air.

Between them, the two large cities were granted most of the available VHF channels.

VHF channel 12 was added following the new channel 11 to compensate for the change.

However, there were significant cities that had few or no VHF channels allocated to them.

By the early 1960s it became apparent that the 10 VHF channels were insufficient to support the growth of television services.

The station launched its digital signal on VHF channel 10 in 1999.

This required a reassignment of the VHF channels to the plan currently in use.

At the same time, it became clear that the designated VHF channels, 2 through 13, were inadequate for nationwide television service.

The station aired an analog signal on VHF channel 11.

It had previously aired a digital signal on VHF channel 2.
