Only managed to positively identify you at 2300z - my double-decimation software for the EVM generates a spurious line right where you were at the lowest rate so wasted about 6 hours recording yesterday. But at 3.125Hz sampling rate it just isn't there so found you eventually and left the S/W recording. During the night not a not was visible on the real time display, but at 0700z as the noise level was falling dramatically (very likely to be street lights going off) there was a particularly good set of long and short dashes. I'll leave recording for another couple of hours then post process the raw data and send you a plot. Must investigate the spurious line at the lowest sampling rate - wonder if the digital filtering process is throwing a wobbler at that rate and is alliassing in a strong signal somewhere else in the band. The spurious line moves in tune with the software Local Oscillator so alliasing looks a strong possibility. Andy G4JNT
