HI Dave,
Glad it's all working for you, perhaps see you on qo-100 sometime.

Re: Pico tuner help
The Picotuner (actually the NIM in the Picotuner) does take quite a lot of current if powered from USB. Technically it is more than is recommended for a USB device and may be pulling down the power supply you are using for the Portsdown.
If this proves to be a problem then the Picotuner can always be powered externally from 12V.

Re: Pico tuner help
D8 is just a diode and D6 is a TVS diode on the PCB, in the Schematic and in the BOM - are you reading the right files for V3?
