Hi Yas, Maybe UW8SM? It is likely because the signal is pink on DF6NMs grabber. 73, Stefan Am 06.10.2014 23:49, schrieb Knight Ao: Hi LFers, Who is "SM" currently on DFCW around 136171? I can see him
Hi ELF friends, Now the circuit is in a box: https://dl.dropboxusercontent.com/u/19882028/VLF/Living%20in%20a%20box.jpg I measured the resistance against ground (which should be infinity!) with an ol
Hi Manolis, Nice photos. Will you build a 1000W PA soon? Spiros knows how it is done :-) Impressing results for that station. I bet it is also due to the low distance to the sea water... 73, GL, Stef
Hi ELF, This afternoon i'm attempting to transmit on my INV-L on 136.172 Hz (not kHz!). Just preparing my H bridge VLF PA and i intend to use an old 10 kV transformer which i got from an old furnance
Hi Markus, Thanks for the calculations. We will see the results. I do take care. In my promotion project at TU Darmstadt i daily worked with a capacitor battery having 15 kV / 12000 uF, see an image

Hi ELF, Unfortunetely my HV transformer got (obviously) an internal short cut during transmitting on 136 Hz. With a scope and HV probe i measured nearly 10 kV rms on half the output. So there must be
Hi Mike, Congrats! I will try to leave a decode on your side too :-) 73, Stefan Am 12.10.2014 06:57, schrieb Michael Sapp: Hi All: Nice to see G8HUH show up on my wspr2 screen ~:))) http://i129

Hi LF, I continued with my garden remote VLF/LF/MF RX site. It is amazing what the Raspberry PI can do! :-) I'm not an expert at all (!) but i managed, of course with help from the web, to start and

Hi ELF friends, Just for those who are interested... I have now finished my modifications to the ELF RX / preamp design for a long wire (E field) antenna. This is the final schematic https://dl.dropb
Hi Markus, ELF, Oh, maybe you're right. The spectrogram is in 45 mHz and 5 s/pix scroll rate. Attached is the recording in 11 mHz and 30 s/pix, see the long-term average graph, red. No noise blanking
