Antenna 27 is jumping on every scan at X-band also, on the BD side
only.
But it's not the only one ... from my 'Herc A' demo run last
Thursday night, I find:
Antenna 26 if jumping on AC IFs at both C and X bands.
Antennas 18 and 27 are jumping on BD IFs at both C and X bands.
In addition, antenna 3 has very poor phase stability --- not
jumping, but 'wandering around' on all four IFs at C-band.
