I'm sorry, i forgot to mention that i'm getting my EbNaut decodes from
the exportet FFT data (text files) from OPDS. That means the
transmission must be somewhere arround 137.5 kHz +- 50 Hz.
Maybe i can search for a PC with 64 bit here in the institute to decode
your 155 char message. I still have the text file :-)

OK Stefan, lets try a shorter message (54 chars) tonight starting 2300
utc and every 15 mins. 150 watts 2 amps RF. 137.777 kHz 1432 0.2 s
I like my 32 bit machine too!
Thanks for the helpful advice Markus. I noticed the different colours
on your grabber. Will go for a shorter message this time.

Unfortunately it looks like the EbNaut decoder can't decode 155
characters on this PC (4 GB RAM). The number of characters seems to
be limited to 66 :-(
I don't have any 64 bit systems available here.

Reports of the OP32 sigs from R7NT, F5WK, Graham, Markus, Hugh, Stefan
Dominico and others who I inadvertently left out are gratefully
Tonight by popular demand starting 2330 and every 15 mins, EbNaut 155
chars 0.2 seconds 771.2 s message duration, 4K19A polynomial. 500w
3.5A to the 100m RL. Reports most welcomed. Good luck to all.
(Let's hope I've set it up correctly!)

Thanks, very nice. 131 characters in 0.2 s symbols, that's great!
Joe, could you run a similar transmission again? Maybe with a
longer text :-)

Is it right that you sent some EbNaut with many symbols on LF in the
past (last season) ?
I didn't give it a try that time. Now i would be interested in a TA
detection of an EbNaut signal.
Which symbol length did you choose that time?
