Last week Phil gave me the old POP X IN-AIR WFS PD as our JAC WFS A PD had a wobbly pin on the Q3 LO output.
Masayuki had tried connecting to this with both cables we had.
When I tried plugging in the Q3/Q2 cable on the POP X WFS I realised that one of these cables itself will not seat on this connector properly. I tried with the other cable and this one connects to the Q3/Q2 output on POP X ok.
I will get together with Phil in the new year and investigate more.
