Hi Jay,
A funny story. Would like to see a capture of the cat instead but this
is OT. Or is it a special LF-cat, beeing able to decode OP8? :-)
Last night, Martin/YV7MAE and me, we actually successfully saw a first
effect of the E-H antenna combiner, using the circuit i recently
published here. There was a 3 dB S/N rise/fall of the DCF-39 carrier
when switching from front to back. We almost stopped to try to have some
success with this hardware due to various problems. Now we must
carefully learn how to adjust the pot for optimal noise reduction. Also
we have to test if better results can be obtained when changing the loop
resonance frequency. 3 dB is not much but it is a first interesting step
and it allows to see what is NE and SW :-)
So this is why i want to try some DFCW-90 at night but i may switch to
OP8 automatically, somehow, late at night. We will see.
73 and tnx!

Good thing John was watching ... cat apparently spun the tuning dial
and I didn't notice until morning. Cool nights now so the cats like to
sleep on the warm receiver. Will engage dial brake next time ;~)

Hello John ,
OH! Good work, congrats to your receive equpiment! That is amazing. In
the first moment i thought there were no decodes in our test because no
red lines are shown in the pskmap. But later i found them in the text.
Many thanks for the test. It's nice to detect that peak of best
propagation, in 8 minute intervals. In a spectrogram it would work as
well of course...
So i still don't know if Jay got some results too?
A summary of detections showing up here is attached (all T/A and the
highest S/N of the others)

Stephan,
Well, I had four "hits" last night:
02:44 136 DK7FC de WD2XES Op8 3714 mi -30 dB in Holden, MA USA
02:36 136 DK7FC de WD2XES Op8 3714 mi -29 dB in Holden, MA USA
02:28 136 DK7FC de WD2XES Op8 3714 mi -29 dB in Holden, MA USA
02:20 136 DK7FC de WD2XES Op8 3714 mi -30 dB in Holden, MA USA
That was in the time frame of a single OP32 transmission, and must
have represented a nice signal peak.

Hi both,
Many thanks. It's 4:10 AM here now and i will take some sleep i think
:-)

Stephan,
I just got home at 0200Z, and will leave the receiver running in OP8
overnight.

Jay, LF,
After finishing the next sequence in OP32 (hopefully reaching
UA4WPF) i
would like to try OP8 over to W1. Would you like to try?
