Hi MF, Could someone run WSPR on MF for the next few hours? I'm again checking my MF station in the garden and would like to make some SNR measurements between the main and /p QTH. 73, Stefan/DK7FC P
Wow, thanks for the very high activity. Special thanks to PA0A who sent a signal that was strong enough to make the daytime groudwave distance. Unfortunately i had to go before the band opened becaus
That is crazy, it seems nearly everyone who has a transmitter and antenna is on air now! On the map i just see coloured lines :-) More, more, we need everyone! :-) 73, Stefan, stunning Am 14.08.2014
Hi Warren, Cheap devices for 3 EUR (or $) will do most jobs very well. But it may be worth to spend some more money. 192 kHz sampling rate is available for a low price. But you may first try to insta
Hi Spiros, What kind of RX system is he using there? 73, Stefan Am 16.08.2014 01:13, schrieb SV8CS- Spiros Chimarios: Yes SV3DVO is in Queens, NY, USA address 196 str and 53 Av.(loc 40 45 16 N and 7
Hi all, I've just started my WSPR-15 transmissions for this night but was a few seconds to late. So the first slot will be 22:30 UTC. Will someone join to LF? 73, Stefan (operator DWS) ;-) Am 20.08.2
Thanks Mike. Obviously my TX power is about 6 dB lower because of a temporary metallic construction near the antenna, which brings my variometer to the lower end, i.e. the maximum resonance frequency
Hello Luigi, That is very nice! Good luck with your QRP transmissions. For you it's easier to add another 6 dB of power to your signal than for me :-) My WSPR-15 LF RX is running 24/7, so maybe you w
Hi Markus, Yes, Jay picked it. A good surprise. OP32 is about 100 Hz lower in frequency, maybe this is more promising ;-) About the reactive load: If i just run half of the antenna current, the PA ha
Hello Bill, Jay, Did you copy me? I just found the last image from the morning on your grabber :-) Tnx, 73, Stefan PS: Thanks Jay for watching and the grabber service! Am 22.08.2014 02:47, schrieb Bi
Hi Markus, Same mode, same QRG :-) Let's be traditional this evening ;-) 73, Stefan Am 22.08.2014 21:49, schrieb Markus Vester: Thanks very much to Bill, Jay, John, Mike, and everyone else who might

Hi, My 20W solar module for the remote VLF/LF/MF RX site is now ready to be mounted on the tree, see image: https://dl.dropboxusercontent.com/u/19882028/20140823_150112.jpg Also the RasPI arrived a f
Hi MF, Thanks for the transmissions. There were a few stations detectable in daylight, listed below. From the garden i got 31 spots, from the urban location just 12 spots! The garden seems to be the

A very clean spectrum (no QRM) ! Pity that the preamp has a cut off frequency arround 4 kHz. It would have been interesting to see what happens arround 2 kHz. Did you try to receive ZEVS too? 73, Ste
