GPS PCB adapter on port 3 inside sw3b DSM was shifted by one pair of pins. Fixed, and it is now reporting and has sat lock.
Bottom pair of pins on port 3 in sw1b DSM were bent over, and not connecting. I think they were the 3.3V pins. Straightened them and reconnected. GPS is now reporting, but doesn't have sat lock ("V"). This is in an ITS box shelter. I moved the GPS so that it is pointing up, but still no lock. This is not critical since it can get time from the chrony server on sw1t.
I believe the only other GPS that does not have sat lock, reporting "V", is also in an ITS box at ne3b, and can get time from ne3t.
