I repeated Rick's 5-band, 0.4 sec integration, on-source-off-source test
yesterday. After that I had queued up tests of frequency switches to see
if L302 returns in phase to previous settings. The EVLA antennas produced
basically nothing. The only sign of life was in the first scan, at
L-band. Ants 14 and 16 had about 2 minutes of fringes with amplitudes
that started out OK but then dwindled, as if the antennas stopped
tracking. Ant 16 showed phase winds within this period. Winds were
moderate to high throughout. AIPS shows the elevation/azimuth increasing
-- not sure if this is commanded or actual though.
