Yes, digital TV replaced analogue transmissions. For regional viewers, that did not go well. In the Hunter Valley, channels which had used VHF switched to UHF. Premises that could view the old channels suddenly had nothing. For distances, UHF is worse than VHF and digital is worse than analogue. Our government auctioned-off the VHF spectrum that had been “freed” by the transition. They called it the “digital dividend”. It proved a nice little earner.
In Australia, DAB+ is transmitted at around 200MHz. FM broadcasts centre around 100MHz. AM radio is generally below 2MHz.
In the future, look out for Digital Radio Mondiale. If adopted, that will take over existing AM frequencies. There’s an extension known as DRM+ which targets the FM band (and VHF TV).
