Hello Joe, You've been transmitting QRSS-60 the last night. I've seen you in my new splitted QRSS-10 window, see http://dl.dropbox.com/u/19882028/10_168527.jpg The signal is readable but could be a b

Hello Lubos, Sorry, i haven't seen anything it seems. But 600 km by using 25 W at 8970 Hz would almost be a wonder :-) Go on and good luck 73, Stefan Am 11.03.2011 13:47, schrieb Lubos OK2BVG: Hello

Hello Lubos, Unfortunately i cannot see something but today QRN is high here in Heidelberg. There seemed to be some interruptions in your transmission. Do you know why? 73, Stefan/DK7FC Am 30.03.2011
Hi Uwe, the test lead of the oscilloscope in use has a resistor of 10Mohm. The oscilloscope advise text says that I have to multiply the result by 10. OK. I added two other 10Mohm in series multiply
Hi Roger, Chris, Very nice, congrats! A new UK record, isn't it? The frequency looks very stable over time. Maybe Paul Nicholson could try as well? I'm sure he would catch him! 73, Stefan/DK7FC Am 03

Uwe, VLF, You are visible in Heidelberg in my "DFCW-6000" window now since the QRN decreases. Just about 8 dB SNR but it becomes better... Good luck and fun with your impressing station! :-) 73, Stef
Hello VLF, Uwe/DJ8WX, i saw your signal but significantly lower than before some days. You can see the difference in the 60000 window. There is a stronger trace before and then the recent transmissio
Hello Joe, LF, You've been visible in my QRSS-10 window in the early morning here, although my grabber is pretty in-sensitive in the moment (i shot my first input stage during TXing on 137). See http
Hi Roger, I'll choose a different subkect now, since it gets confusing slowly ;-) With wideband i rather mean a window that shows 0...24 kHz (if your samplerate is 48 kS/s). This allows you to check
Hi Roger, Paul told me once, he is recording 24/7 and the data is stored a few days until it falls out at the end of the stack. So there must be a chance to find Chris's transmission, since the trace
Hello Henny, Uwe, VLF, Ah, you've already seen it ;-) I just wanted to post that i have splitted my 60000 window. Now the range arround 8970.000 +- 4 uHz and 8970.020...8970.025 is visible. Since it
Wow, the next one! Lubos, can you tell us about your station? All parameters and data please :-) How strong have you been visible at OE3GHB? Welcome in the VLF TX group ;-) 73, Stefan/DK7FC Am 09.03.

Hi Eddie, Ossi is well visible in my 6000 window as well. So if you run the same settings, you should achieve about the same results, regarding frequency, time and drift (and except my local tests of
