Now i have added a wav (audio) file of the SAQ message of last sunday. Very fine CW reception. Even the carrier during key-up was audible... I used a 300 Hz CW filter and a noiseblanker (15 dB trigge
I just saw that Mike/G3XDV appears very much stronger on my grabber after 19 UTC while he is much stronger before 19 UTC on the DF6NM grabber and almost invisible after 19 UTC. The difference of dist
Dear VLF, i have created a google earth picture where my current VLF receptions in DFCW-600 (sri, just above 200 km) are displayed, so one can get an impression of the different locations, distances
Dear Chris, This is a very pleasing message. I am happy and proud about this. :-) Well, 2872 km is a real heavy challenge! But surely i will try to send you a suitable signal (seems, i need a new gen
Hello Con, Thank you! The Alphas are currently off. You can check it on my VLF grabber if you want, it is running 24/7: http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber.html There is a
Hi Laurence, You know, it depends on the WX. Most people are interested in the weekend. So i try to do it on the weekend. Maybe i will do the 8th experiment in 2 weeks or so. I hope so. The wind is s
Wow, Thanks Peter! How have you found that? By guessing? :-) 73, Stefan Am 10.10.2010 16:13, schrieb pws: Hi Stefan, You wrote: ... There is sometimes a trace arround 10,6 kHz which looks as a MSK si
Oh yes, indeed. I just saw that GBZ is much weaker in the moment on my wideband window, also DHO38 but not so JXN and all the 3 Alphas (which are stronger than in the last 13 hours)! The MSKs traces
Hi Daniele, No problem about the callsign ;-) On VLF you don't even need one for transmitting, hi. Oh, you are in JN53EM, i haven't known that. The distance is 707 km! This is the 3rd best distance a
Hi Jacek, Could you create a picture like plot_80km for distances up to 5000km? I think i do not want to start simulating, my job is in the field ;-) But you have done it and may generate it easily?
Hi Daniele, Am 05.10.2010 17:00, schrieb Daniele Tincani: My reasoning is: I'm pretty sure :-) that I have hum at home affecting reception below 10KHz. Attached you find an usr file. Just let it run
VLF, Here are Paul Nicholsons results of his work on my 7th experiment: http://abelian.org/vlf/ss101002/ Another link: To check distances at given locators check this website, very useful: http://no.
Dear VLF, Its not an easy decision but i will start tomorrow, saturday 23. october. I want to start at 6 UTC but maybe it will be later due to the low wind. The wind might be to low in the early mor
Dear VLF, I have set up a list of the successful receptions of my transmissions on the Dreames Band (33 km) and 46 km. If someone is forgotten or if something is wrong, please report me. I want to pu
Hi Daniele, VLF, Congrats to your successful VLF reception! :-) If you compare your received signal to that of Renato Romero, it is not much weaker. Since Renatos Antenna is excellent, i assume the l
Hi Jim, This capture is taken from your home QTH, rigt? Or have you been out in your car for 24 hours, just to minitor? ;-) It looks nice and very clear with very low QRM, at least above 5 kHz. The s
Dear VLF, The wind forecast for saturday is promising. Tomorrow i have to decide if i will make a VLF kite experiment this saturday, 23. October. 73, Stefan/DK7FC
Hello Piotr, Again thanks for your work. The comparison of the 3 bands is very interesting. If i include the reduced antenna efficiency it is anyway an advantage to transmit on lower frequencies, at
Hi Daniele, Yes, adjust the B slider. But the QRM/QRN must be totally visible on all frequencies. You can increase the input level but it's better to leave it as you usually have it. It is better to
