Hello Joe and Paul, Congrats to that successful TA decode! It would be interesting to see what happens if you transmit the same message to the same time again the next night. Will the SNR rise by abo

Thanks for the report and assistance, Paul. When Stefan tries negative frequencies after having reached DC, Dirac will be delighted with positrons on the e-probe. Will do a repeat transmission tonigh

Neither component decoded by itself: H-field: Eb/N0 -1.5dB phase 40.3 (no decode) E-field: Eb/N0 -0.9dB phase 35.3 (no decode) The noise was just a little higher than average for the time of year. On

cat msg7 | ebnaut -et -N8 -k20 -p16K21A | sudo ebkey -S21 -m rp,gpio=23 -T '20171106 2200' This uses a -k20 option to give a 20 bit CRC. Should still decode, easily if it's an averagely noisy night.

Nothing decoded. It was an average to low noise night and I expected an easy decode but after trying a range of beam headings and blanker settings, I've had no result, even with -f9 and excess list

It seems there was something wrong at this end and perhaps the message terminated early. My regrets for any inconvenience. Will try again tonight. 73 Joe VO1NA cat msg7 | ebnaut -et -N8 -k20 -p16K21A

On a quiet night (or maybe two) it should be possible to transfer 1 character from Joe to me i think. Joe, do we want to try that? I would not transmit during that night then. Paul, did you copy my m

Thank-you again, Paul. Tonight an unmodulated carrier with better phase stability (hopefully). 73 Joe VO1NA cat msg7 | ebnaut -et -N8 -k20 -p16K21A | sudo ebkey -S21 -m rp,gpio=23 -T '20171106 2200'

Thanks Stefan, Yes, we must try this. I will use the SL ini file you sent me. Tonight a pickup wire is feeding SL to improve phase stability. 73 Joe VO1NA On a quiet night (or maybe two) it should be
