Content preview: Hello Paul, Thanks for the overview, good to have. The phase is always very interesting to compare, we can now say it varies less than +- 10 deg, not bad. I am in contact with RN3AUS. So far he got no decode. He provided the txt files containing the daily data to me. We already thought about asking you for help. But i like to transmit (at least) for 10 nights before i give up. Yesterday we got a set of 6 days. I stacked them in Markus' stacking tool for windows. The individual days are normalised by the square of the rms voltage. I tried to get a decode with and without normalisation and with all six days and also with just the 5 best days. No decode. Unfortunately the QRN gets higher each day in the moment. 4 days could have been enough but that was based on days like 7th/8th. We will see. It is a good tutorial to train patience :-) Meanwhile the day time transmissions will give faster results and are a chance for more stations.

Is the 10...12th with or without E field?
