During that time, I changed the Turbo Rogue reference frequency input from the internal crystal oscillator to the VLBI hydrogen maser. The receiver had been operating on its internal oscillator for several months and the GODE Turbo Rogue lacks the clock steering option. So you should see the clock offset drift for GODE drop significantly. At the same time, I changed the radome covering the Dorn-Margolin antenna from a fibreglass "dunce cap" to a hemispheric plexiglas unit. Thanks to Steve Dinardo at JPL for sending the new radome!
