(S2100737) - Debugging showed that the opamp, AD822ARZ, for PD2 circuit was not working as expected so we replaced with a spare and this fixed the problem. Somehow, the PD1 circuit no longer presents any issues, so everything is now fine with the unit.
(S2100741) - All good.
Trying to finish 2 more Sat Amp units so that we have the 7 units needed for the X-arm install.
S2100736 - All good
