Attached are measurements of your carrier from midnight until 16:24 today. The carrier phase plot (centered on the nominal frequency) seems to show a general downward curvature presumably due to oscillator offset and a slight drift, superimposed by the diurnal propagation phase advance between 8 and 11 UT.
I'm wondering if Edgar managed to pick up your transmission in Tassie...
The indicated Eb/N0 is the one based on the symbol error rate, and a high value just indicates that no errors had occurred for that decode.
Best 73,
Markus

A lovely bit of annimation, but no sidebands for me to see. Paul mentioned a carrier so 4 amps at 137.777 kHz (-0.255 mHz) to the rotated L aerial starting now until 1130 tomorrow morning. Incidently Markus, Tangles was a bit sceptical about the 75 dB Eb/N0 at 0200. Did the noise become infinitesimal? Switching on the PSP now for a long carrier. Good Luck all! Joe VO1NA
