This is exeactly what I've done.

There is a subtle entry in the log

2020-06-03 10:27:29.993036 W [27922/27922] CoreContext dtvmultiplex.cpp:340 (ParseDVB_T2) - DTVMux: Undefined modulation system, using DVB-T2.

What is. even more frustrating I put my lucky-packet cards in (Leadteck that pixcelate on HD) and everything works perfectly with no further setup.

I'm now trying John's setup with 'buntu 20.04 (and people hate 'me too' type posts, but sheesh they help lots)

I'll post what happens

Thanks
