Hi VLF friends,Since 11:35 UTC i'm running about 2.5 A antenna current into my 900m long ground loop antenna. Frequency is 8270.01 Hz. The signal is very strong on my own grabber in 57.6 km distance but also at DF6NM, DL0AO and it looks like there is a peak now on Paul's spectrogram building up slowly. I intend to run the carrier for 2 hours or so, until the accu is almost empty :-) The H bridge PA voltage is 175 V and the power consumption is 450 W.Today, the DC measuremant result is 66V for 1 A antenna current. It is cold and wet! More soon. 73 de DK7FC/P in JN39WI PS: The QRN is exceptional low!!!! |
