One of the electronics technicians was called out on Sunday and thought the problem was fixed; however, we still continue to experience difficulties and believe this has affected the data for BK121C at the VLA. At 19:07 IAT, we switched the synthesizer setting on the antenna dedicated to BK121C in hopes that this would solve the problem. Everything looks good here. Mike, please let me know what you see in the data. We apologize for the inconvenience and any loss of data. These synthesizers are a bit of a nightmare and will be gone with EVLA. Cheers, Pat ps - It is due to Ken Sowinski's knowledge that we were able to attempt a solution here.
