Allthe high frequency feeds were alignedand braced this morning.
Ka and Q band still look fine.  K band, however is still dead
in the sense of no fringes.

I pointed the array at the Sun while at K band and ea13 showed
no change inTP while other antennas increased by 20 dB or so.
Is it possible that the feed cover was never removed?


Another, independent, problem is that the power into the T304
for IF B, and only IF B, is much to low when setup at K, Ka
and Q bands, but not at Ku band.  In these tests the direct
path was used for both IF pairs at K band and higher.  Looks
like a problem in the T303.
