But my ERP must have been higher during the 1 hour transmission. There must be some propagation effects here!! Furthermore i saw that your QRN (not QRM i suppose) is already coming up during the "GM" message on my grabber it started to rise at about 17 UTC, so about 6 hours later. My final transmission on 8970 Hz, arround 15 UTC, is the strongest signal on my grabber although i know that the kite was lower and TX power about 3 dB lower, additionally. So, maybe we should watch these transmissions more carefully. Is it possible, that not just the signal but the SNR(!) comes up just before the QRN is rising again? OE3GHB's 5170 Hz capture also shows that my transmission was done during the QRN started to rise at his location! We might take a look on this effect within the next tests!
