Digital TV is superior to analogue but cost and complexity has always been a problem, until now! Just by using cost effective off the shelf components you can upconvert to any frequency in the 23cm amateur band or even higher!

ATSC 3 should work as well when equipment becomes available. Here in North America, it is 6 MHz.

Is there really more local DVB-T than DVB-S on 23cm? Most 23cm DATV I have read about was DVB-S, due to the ease of modulating QPSK and satellite TV receivers working directly for receiving it.

What you say is true but for those that want to go DVB-T this is a "home brew" way of doing it. Our local ATV repeater has both DVB-S and DVB-T inputs. DVB-T does have an advantage in hilly terrain in reducing ghosting problems. The hardware way of producing DVB-T means just a power button is pushed to transmit. When software is used to produce DVB-S a series of tasks have to be undertaken with re-starts sometimes required.

The Terrestrial modulation just happens to be superior for Terrestrial applications :) Very nice to hear that your local repeater has both DVB-T and DVB-S inputs and that 23cm is getting used.
