I have just done a scan in non freesat for FTA channels. (HDR-1000S).
Found 129 TV and 28 radio.
Channel numbering starts at the first channel found as 5000 (channel 4) on 28.2E. You can delete and renumber using lcn 5000. 19.2E will be different.
First channel found will be Mainfranken HD

While in non freesat choose editable channels.
Unlike a Foxsat-HDR you cannot record non freesat nor use time shifting.
