Hi Eddie, VLF,

Thanks for watching! The = spectrogram=20 looks fine and i haven't expected that S/N from my low ERP i have = here.=20

Since 10 UTC i switched to DFCW-600 which is well visible at = OK2BVG http://www.ok2bvg.cz/vlfgrabber= /=20 but the QRN is higher than in the last days.
Strongs wind comes up = here=20 now, so maybe i have to QRT soon. If not i will try to transmit my = complete=20 call in DFCW-600.

All in all i think the transmissions on the = fixed=20 antenna look promising if i can add another 6 dB but a real kite = experiment=20 with the 300m vertical just gives a 20 dB stronger signal and allows = better=20 detections in a shorter time. I also like the transmissions on 5170 or = 6470=20 Hz.
