[evlatests] maintenance day summary

[Ken Sowinski]

The 'smoke test' was cancelled due to snow.

Correlator boards were rebooted.  Most useful change is
fixing the 'dumptrig problem' which made complex recirculation
or integration choices unreliable.  This has been tested
only to show that nothing that used to work was broken.
Only one complex recirculation configuration has been tried.
A complete summary will appear on widar-wg.

ea11 is working well enough for pointing tonight.  There is
a broken power detector in t304-c, but it does not prevent
pointing tonight.

New (or replaced) receivers:
L band at ea18
S band at ea07
Q band at ea11

All 28 antennas are available for testing.  ea11 is probably
not ready for astronomy yet.
