still aural copy of your
signal (which would even be=A0stro= ng enough for CW) on 478,7
with S4 and a SNR of 6dB in 100Hz = BW
despite the surrounding photovoltaics arrays which are ubiquitous in
Bavaria.
But I have to resonate the dipole exactly and what is even more
important I have to balance the 43= m long feeder strictly
i.e choke common mode currents
Otherwise I would hear only noise = at this time of the day.

OK,sorry,=A0I see now that 477 is *dial* qrg.
Your sig is S9+=A0on 478,7kHz.
=A0
DF0WD is S9 with qsb on 472,5kHz now.

MF!

I just started my TX in OP4 mode on 477 kHz dial. Will run in until sunday evening. BTW the PA was not damaged, it was just a under-dimensioned fuse which i used for the first tests and forgot to replace it by its actual value. Now the transmission should work without interruptions, i hope.

Would be interesting to have some 24 hour monitoring data of the complete saturday, so if you like to take a part in this "study", pse run the RX during that time :-)


Tnx and 73 to all, Stefan/DK7FC
