There was a question yesterday about the blends we are running on the the BSC-ISIs. I'm attaching plots of the Quite90/250 and Windy90/250 blends. Pages 1-3 are the 90mhz X/Y blends, 3-6 are the 250 RX/RY blends. The Quite blends are what we are running currently on St1 in XYZ (90) and RX/RY (250), and there is some evidence that we can run them during windy times as well. The Windy blends are kind of untested, and don't currently run on the end station ISIs, I don't know why and I haven't had much of a chance to look into it. The end ISIs will switch to the Windy blends, but trip after a few seconds. Pages 3 and 6 at least show that the filters as installed on ETMY are properly complementary, ETMX is the same.
For comparison, here are the Quite blends compared to the LLO blends we used previously. Pages 1-3 are the 90 mhz X and page 4-6 are the RY blends. Pages 2&5 are probably the clearest to look at.
For fun, here are the HAM 0128 blends. Page 2 shows the complementary form of the X and RY blends, page 1 is the as installed version.
