Sorry, the transmission failed right at the beginning. The sun heats up
the coil and detunes it even more it seems... I also found that the
series impedance of my ferrite transformer between PA and coil seems to
be to high, limiting the antenna current at resonance. I use the
transformer down to 970 Hz but at 17 kHz it seems to have just to much
primary and secondary turns, along with the stray reactances...
