Thank you for
the phase info Markus
Can recall
that the first tests last spring with same power and U3 were phase
coherent
But my U3
suffered a hard reset and turned back to factory default parameters, so probably
the park function
makes the
difference. Will set it and test tonight
The other
difference with previous test is that I'm not transmitting continously. Only one
frame every hour
starting at
minute 45
Thank you
Stefan. The variometer in L1 is at minimum. So it is easy to add a bit more
inductance
Will be better
to add a bit more power soon and see if we can go for QSO
;-)
Thanks
a lot for the transmission, and the report on the report ;-) Nice setup indeed
on top of your roof!
I believe that the U3 by default does not
preserve phase between dashes (possibly depending on a "park mode" setting
but I'm not sure). If you could make the transmission
coherent the opds correlator might gain another 3 to 4 dB
sensitivity.
All the best,
Markus

Hi LF
Last night the LF coils were connected
and started to transmit Op32 with just the 100mW from U3
So far, an Op32 correlation decode from
Markus. Nice Rx Markus ! :-)
Who's next ?? ;-)

I have tested the effect of the Ultrabeam dynamic antenna I use as a support pole while
working as variable capacitor. I can get the resonance 15KHz down by extending fully the internal
metallic element of the vertical antenna. A great aid for remote tunning from shack
