Subject: OLI/KASACR/M1 - PPI Reverting to Single Pol Mode
Affected Datastreams: olikasacrppivhM1.a1
Description When switching to ppivh mode, one of the boards that controls transmit switching is getting confused and defaulting back to single pol mode (So it is transmitting on H, but not V). This also causes the drop in rhohv as it's correlating the H return with what is mostly a noise field (Plus the cross polar signal).
