1. 18:25 to 18:45 - L band, many sources over a patch of sky about
    20x20 deg. Phases are flat (on each scan) and very clean, no hint
    of dropouts. (0.4s integration)

    There is still a large dependence of phase with sky position,
    with W/E signature, only on VLA baselines. I have not tried to
    fit anything, but it seems clear that the ~1m baseline offset
    between E/VLA persists.

2. At 18:46 at the start of a scan the phases went loopy on VLA
    antennas: high rates for one scan, then fringes gone for the
    rest of the time. EVLA-EVLA baselines still good.

3. The sysstart scan on 3C84 at X-band was also fringeless on
    VLA antennas; EVLA-EVLA stayed good.
