Hi Eddie, Markus,

Thanks for the decodes, your results are very good.
Hopefully the message can be decoded by Alex too. Rain caused the aborting of the early transmission.
Tonite i want to try 10 ch again.

f = 8270.100000 Hz
Start time: Sunday 05.Mar.2017   18:00:00
Symbol period: 27 s
Characters: 10
CRC bits: 15
Coding 16K21A
Duration: 11h, 24m, 0s
Antenna current: 700 mA

Then, during the week, i would like to try to send my full callsign to Eddie in DFCW-6000. It could work, he can see me day and night it seems :-)

A beacon with 5ch, 3sec and hourly repetition would be interesting too....

73, Stefan

Good copy in Northampton UK IO92ng16, last two figures give me an extra Km. Full decode sent to TX HQ for confirmation.
