Summary | 0000171: Some problem at 6cm VLBI settings | ||||||||
Description |
There are some cross talk between X and Y at 6cm VLBI settings: (see 10904478) The problem can be seen on RT2,9(MFFE-04,06) and there are also bad shapes of bandpass of 3X*X(MFFE-09) at band7. According the experience they could be caused by the condensed molecules of air with 20K which come into 6cm receiver. Could we try to solve these problem before the coming VLBI(22/10)? (just let the MFFE warm up and cool it again) |
