| 1510 | Disconnect Stripline 41, remove SQUET ZC-26 with accessory diverter board still attached from East tower face NOTE: found one pin on diverter board bent out of place… This appears to be Pin47 on the Stripline side of the SQUET. That would be a redundant pin: it's one of four QETB returns. DIB4. (question: is it one of the diverted wires?) That's Side1 pB, we didn't have any problems with that channel. And looks like this pin was not used for an accessory. |
