John, radiate because of energy vortexes, which only a genuine, authentic, patented Kabbary-tuned CFA can produce properly! < Something for christmas (sorry xmas): Get a bottle of "Antennosol", spray
Hi Larry, Spectrum Lab has been tested with the Audigy 2, the 96kHz sampling rate seems to work but the amplitudes are lower than expected (maybe some fiddling with 24-bit samples required). The "old
Hello group, received this colorful image under adverse conditions: Random wire plugged into a TS850, tuned to 135.92 in "CW" (usb), pitch = 650 Hz, so 650Hz on screenshot is near 135.920 kHz . The d
DC (or B!)F39 or Loran lines via this link - using QRSS 10/30/60...or not. < At the moment, its really DCF39 transmitting there on 138.83 kHz. I wrote a crude FSK demodulator + decoder for it (based
Hi Brian and group, Yes, it's you. At the moment, there is the possiblility to compare the signals.. see for yourself. The drift is on this side. Good night + good luck to all, Wolf DL4YHF. JPEG imag
For heaven's sake, Brian, how many kilowatts are you feeding into the antenna ? I can copy your signal with my "home"-equipment, which is an untuned wire plugged into the TS850, lots of local noise.
Steve, Damnit, now you got me ! Well ... I listened to "Radio Cure" on the "Yankee Hotel Foxtrot" album (found as audio sample at amazon) and it sounded dreadful - must have have been a bad day befor
Dear group, I received a mail today with a *.PIF file attachment which contained the CLEZ virus. Fortunately, due to NOT USING MS Outlook here, no harm was produced, and the anti virus software alert
Hi Gary, Which type of windows are you using (W98, NT, or..) and what is the video mode (256 colors, "high color" (65k colors), or "true color") ? This would help to trace the bug. I am using "true c
Dear Arnie Jim's article about LF RX loops is available from here: http://members.aol.com/articles4lf/index.html or from there (G3YXM's LF site): http://www.picks.force9.co.uk/ Usually Dave's site ha
Hi Jose, Congrats for hearing DJ9IE, quite likely the strongest LF station in Germany. About audio filtering: If you need a simple program, try Alberto's Spectran (from www.weaksignals.com). On my PC
Hello Jim and the group, Just to have a "second source": I have uploaded Jim's loop article to my collection of LF articles at http://members.aol.com/articles4lf/index.html . Compared to G3YXM LF pag
Dear Jim, file of about 340kB. It is too big for the reflector, but if you are interested, let me know, and I will e-mail it to you as an attachment. < Yes please.... and if you agree, I will upload
Dear all, Received this from another group, may be interesting for the lucky holders of a 73kHz NOV. Regards, Wolf DL4YHF (snip) -- From: "Myrton" <[email protected]> Subject: MSF Update I thought some f
Hello Group, Sorry this is not LF but VLF (which is more interesting to me these days): I observed a frequency change of the three russion "Alpha" (RSDN-20) transmitters. At the moment, they are very
Hi Steward, Andy and group, I am not sure about the physics of this. The 90deg phase shifter has to be some sort of dispersion device (propagation time varies with frequency), and this will operate o
Hi Andy and group, forgotten to mention this in my questionable explanation: For "adding" the 90° phase shift in the sin() and cos() arguments, it's most important that the arguments are positive, wh
Think I got it... The output from the upper mixer branch is: sin(a+b) - sin(a-b) The assumption "delayed this by 90 degrees" should give cos(a+b) - cos(a-b) does not look right in my opinion. Instead
