A quick summary what doesn't work.  Most of this is
known already, but I have put it all in one place.
I turned off the T_sys correction to get a measure of
relative G/T for all the antennas, and did not use
referenced pointing.

L band
13BD is dead.  The MIB in the l301-2 is not responding.
13AC seems a bit poor compared to the other antennas.
21 is poor and it can't be pointing as it is at K band.

C band
16, 21, 23 and 26 are all not there, as expected.
17 is rather worse than the rest of the antennas.

X band
13D looked worse than most IFs; it was a delay error.
13CD seems to be worse than anything else at X band.
24D is saturates TP at the T5.  ALC and SD are OK.  Downconverter???

K band
23 is not there
21 has poor G/T; could be pointing
24 has worse G/T; not pointing; T_sys looks too high?

Q band
17, 21 and 26 are not there, as expected.
18 and 23 have poor G/t; proably pointing.
