In my announcement for the 8 character message i forgot to update the "duration" line. Of course it should be 23h 28min 0 sec. The transmission of the 4th was unintentionally interrupted, as explained in one of my previous mails.

I'll do some minor optimisations on the coil now and will be back again soon. There is more than one request BTW.

So i will run a carrier on 5170.001250 Hz then.

73, Stefan

Hi Stefan, Paul,

so that  makes a fine record of 5.17 kHz successes between the two of you! Wonder what will be possible when Stefan goes to max voltage on 2.97 kHz?

I'm trying to keep track of the 60 s PSK traces on the tree grabber. There was a 12.5 h transmission on Jan 4th, and a similar one lasting 23.5 h on 5th/6th. As the duration of 8 characters 16k25 should be 23h 28min, the latter was probably the right one.

I'd still like to look for a daytime carrier here, 1.25 mHz below or above 5170 Hz.

All the best,
Markus (DF6NM)

Easy decode, +3.3dB with constant reference phase.

Decoder continues to run, I expect a better decode with
some phase pattern that compensates for the day/night
shift.
