Ditto. We went from having five channels, one snowy on a bad day, plus a bonus 6th channel when the stars aligned, to two channels at best.

The broadcasters and regulators took a basic fact about digital signals "We can get a better quality signal with less transmission power" and saw it as a challenge to set up their digital transmitters with the most conservative estimate of minimum power required. I haven't studied well enough for my amateur radio exam to know if I'm comparing apples to oranges, but I'm still shocked to see descriptions of transmitter power go from 100kW in one case to below 20kW.
