If you are powering the picotuner from USB then you may have problems running both the Pluto and the picotuner at the same time.. Both take a lot of current and the Pi USB ports can shut down due to overload. You may need to power one or both devices from separate power supplies.

Thanks for that suggestion. It did occur to me that power starvation to one or both devices could be the problem.
I tried connecting the Pico from a powered USB hub (which is then connected to a USB3 port on the Pi)
From Menu2, File Menu, List USB Devices, entry 4 is PicoTuner
From Main Menu, RX, Recieve, I get 'waiting for Knocker Tuner'
I will check wiki etc. and (hopefully) work out how to power the Pico from 12v instead of USB

Sounds like you are set for DVB-T which uses the knucker tuner. Try setting DVB-S.

After having it on DVB-T (The Knucker) you may need a re-boot to get it to see a Mini/Picotuner, despite it 'looking' as if its working....
