Normal startup today, except Ant 11 TEC needed rebooting. Ant 14 receiver / is at 33.4 K.
Mark fixed the 27 m at 19:20 UT and the temperatures are coming down, now / around 17 K at 23:00 UT. However, I see that Ant 11 is at it HA limit, / which it should not be, so probably it did not have the right zero pos. Its / data may be bad today. Ant 11 is tracking again at 23:10 UT.
