They had to buy all new equipment for the digital transition. You may
remember they ran their existing equipment on their old channels and
then added a complete set of equipment: transmitter, waveguides,
antennas, STL etc to transmit the "digital" signal while still keeping
the existing equipment in service.

For the stations around here, most of that was their existing backup
transmitter.

If their new frequency assignment iss close to the old one, that
probably was possible. But part of the reason for getting rid of analog
broadcasting was to free up the low VHF channels. Our old Ch. 3 still
appears as Ch. 3 because the TV figures out the translation, but it's
actually on Ch. 8. Our old Ch. 13 is now -- IIRC -- on Ch. 39. Major
equipment replacement needed.
