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
