 Have noticed in this and other runs that 5cx autos on casa in particular change amplitude significantly; network issue (soft start/stop, but ought be calibrated out with memtimers) or antenna issue?
+Phase calibration was difficult. During phase cal gave BF2 to Janusz to do hunt for 8 MHz comb. Eventually tried 5 minute calibration on 3c48 while setting; useful, but not totally enough to completely beat down the solar interference. Final cal used +0.2 caloffset, but probably mistake at this tuning (1660).
+Daytime calibration moving up to 6 GHz did show W3OH and g188.95m, but very weakly and didn't appear to be a good cal.
