ea08 was tried yesterday and it mostly works. C, X, K and Ka band
receivers have been installed. Fringes were seen at C, X and K bands;
Ka band was not examined.
Delays were set at C and X band during startup and a short pointing
run has allowed a determination of preliminary pointing terms for
X band. I suspect something is wrong with IF A DTS because the
delay needed for it is about 350 ns smaller than for the other IFs.
K band seems to have a problem with RCP. Power levels are about
15 sdB lower than RCP and the SD signal is weak or non-existant.
It may be the receiver and not the T303 because Ka band looks normal.
