How to select PicoTuner rather than Knucker?

I'm in the process of commissioning my Portsdown etc. I have assembled a PicoTuner rev3 board. I am powering it over USB, it looks healthy, there is 4.98V reaching the board and the two 3.3V and one 1.1V TP are OK.
If I look at the Portsdown M2-> File Menu -> List USB Devices
I get a list including "5. BATC PicoTuner" so the Portsdown seems to recoginse the PicoTuner
But Rx -> Recieve
Gives me "Waiting for a Knucker tuner to respond"
Can anyone tell me how to get the Portsdown to look for a PicoTuner rather than a Knucker please ?
Thanks & 73, Phil

Hi Phil

Select DVB-S/S2, not DVB-T

Thanks Dave,

As you can see, I'm a complete greenhorn with anything DATV.
Is there a glossary of DATV acronyms, modulation and encoding schemes etc somewhere?
After finding the correct RF input port on the tuner, I was able to receive some pics for the first time :)

If you watch the gb3jv stream there is a comprehensive explanation of how DATV works as part of the carousel. Leave it running as I'm not sure when it's sent...think it's afternoons.
