C1002 #2851 tar-save will be created 2000 Aug 21-22 Processing factor = ?? DOY 234-235 95% have fourfit Quality Codes of 5-9. Algonquin(G): Missed 4 scans due to antenna problems. Gilcreek(A): OK. HartRAO(J): OK. Hobart(H): Due apparently to an intermittent problem with the sampling clock in formatter clipper/sampler B, the singleband delay in channel X8 and all 6 S-band channels sometimes jumped by up to 100 ns from scan to scan. There should be no effect on the S-band multiband delay, but the jumps would affect the X-band multiband delay. Channel X8 was therefore deleted in fringing. The formatter clock was resynchronized at 235-0759, resulting in a singleband delay jump of ~60 ns. Fringe amplitudes in two X-band scans were reduced by 30-40% by phase instability in an LO, presumably in the receiver. Matera(I): OK. Tsukuba(T): OK.
