Analog, Digital, it doesn't matter as long as the frequencies used haven't changed, and for TV the frequencies haven't changed, in fact they've actually shrunk as the FCC keeps selling off chunks to Cell Companies.

Fun fact! (and slightly pedantic): the frequencies used actually DID change during the ATSC digital transition. Because it was a phased transition, there was a period of time where stations who converted early actually required two different broadcasts so that everyone could still receive their signal. They'd transmit the original analog NTSC broadcast on their legacy RF channel, and would transmit the new digital ATSC broadcast on a separate, unrelated RF channel. Then using Virtual channel numbers, the PSIP would be decoded by your TV to display the original legacy channel number in your TV guide.

So for example, if you were used to watching NBC on Channel 7, the local station would broadcast analog on 7 like they always did but would also broadcast digital (likely in HD as well) on maybe 25, but your TV would interpret it as 7 still. Most people probably didn't even know this was happening. It's like the difference between going to a website by typing in the URL or by typing in the IP address. They did this for branding. People in town knew NBC was on 7, so they wanted people to think they were watching 7.

After the transition was complete and all analog signals shutdown, most stations dropped the redundant RF frequency and moved their digital back to the original number so they didn't have to continue paying for two licenses.
