Hi LF Last night the LF coils were connected and started to transmit Op32 with just the 100mW from U3 https://dl.dropboxusercontent.com/u/7162072/fotos%20varias/MF/MF%20and%20LF%20coils.jpg So far, a
Hi Luis, Great! And very nice pictures again. I've been on air on MF last night so there must have been a signal reduction on LF here. Oh, another reason for a LF RX stn on the tree!! ;-) Keep the pa

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
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 parameter
Hi Luis, All right. I will add a bit more power too :-) The often notice that the signal becomes stronger when rising the power level. I found there is a clear dependency, and BTW it corellates with
Olá Luis, one more detection yesterday and three this morning - we seem to have a private LF duct between us ;-) 73, Markus (DF6NM) --Ursprüngliche Mitteilung-- Von: VIGILANT Luis Fernández <luis@vig
Hi LF Yes Markus. Signal must be following some Ryanair path bouncing from plane to plane :-) Since last night U3 transmits continously frame after frame. No stop to GPS calibration So may be the inc

Hi LF Thank you all for the reports But the audio PA is a hell. The good point is that looking at the results with this I can expect a very decent signal when using 50w and a clear output sinewave (c
