- 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!

good video, thanks
Thanks for the kind comment👍
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.
