I swapped the FE outputs on the ea13 Ka band this morning
around 10:15 MDT. I have not closed this form pending
verification via Astro tests.
Note:
I traced the output Heliax wiring from the Ka FE down to the
U/X converter bulkhead, and then from there to the LCP & RCP
switch outputs. The wiring was correct (although the LCP
bulkhead coax at the U/X converter was a bit loose--I tightened it).
