CONGRATULATIONS!!!!!
Seems DinoMode not totally dead yet!!
Sehr gut!

> Hello All,
> 
> Triggered by Peter SM2CEW's tries to complete a QSO by using the ISS as a
> reflector Frank DH7FB and I decided to try that as well. From Peter's
> experience (and also Frank's when SWLing Peter's tries) we believed it would
> be worthwile considering BPSK63 as this would enable us to exchange all
> information within few seconds only (using the EME report and QSO rules).
> 
> However with the first tries on 8 December we quickly had to realise the
> amazingly quickly changing large doppler makes use of this mode impossible
> and we returned back to good old CW since this is also copyable at such a
> situation when you are not 100% tuned on the signal. The second try today
> Sunday 9 December at ISS orbit 51845 starting with a common window at 1626Z
> we copied signals at elevations of > 20 degrees and within a minute
> exchanged all data. Signal reports were about S3...S5 (DF2ZC running only
> 300 watts out). It was a tough task to follow the quick doppler changes and
> also adjust elevation and azimuth rotators. Two hands is at least one too
> few...
> 
> That was a thrill! And now we are celebrating...
> 
> And we will try more QSOs the coming days.
> 
> btw http://www.n2yo.com/ gives a nice live google earth graphics display of
> ISS and other satellites.
