Hi All, I've been making some effort to combine the E-field receiver signal with the orthogonal loops to give 3-axis reception. It is sort-of working. The...
For the first time ever I'm hearing the Russian Alpha signal on 12.09 kHz this evening. Just a single blip from it. Have only ever heard just the 3 standard...
HAARP on 2750, 4500 and 9100 KHz so far this evening. Excellent reception with a junk pocket SW receiver and 12" telescopic antenna, no matter how hard they...
NSY, NRK, JXN to 52N8E: www.electricterra.com/Ernst/20101106_VLFXX.jpg peaks around 6:30 and 12:20 are local stuff. SID starts about 15:30 UT. 73 Ernst...

Note for the ASWLC, PSK31 and VLF Yahoo eGroups, as well as the PSK31 QTH e-list, this is a one time post to let members of the eGroups/e-lists know of the...
Greetings list, in my registrations of the 19,6 kc signal level I found a weak "dip" on 3. November at ~12:2o UT. Caused by the C4-flare comunicated via...
I am planning to reconstruct my loop, on a cube frame made of PVC pipe. To gain stiffness and stability, I need cross bracing. Each face of the cube will look...
In recent conversations, having a very low amplifier input impedance was was preferred, to match the loop impedance. I have attempted to build several low...
I am reading the paper by Marco Bruno, http://www.vlf.it/looptheo7/looptheo7.htm I am looking at the AD797 Op Amp. The device is spec'd for a 50ma output...
I used a signal generator, a 10k resistor and a scope to characterize my loop. I connected the signal generator to the loop, through the 10k resistor and...
Hi group, JFET OpAmp, fast: 50 V/us GBP 20 MHz but delisted and no longer available. May I ask for a recommendation which is available in Germany (in small...
I am making a prototype VLF-Preamp PCB, using a current to voltage converter to get a very low input impedance, followed by an AD620, which I will use for 40db...
Hello Renato and VLF group Any idea of the origin of the 8 kHz signal on the Cumiana livedata ? Appeared on the spectrogram at app 1650 utc today (16/OCT/2010)...
I have been playing with the spice model for a loop antenna. http://sidstation.lionelloudet.homedns.org/antenna-theory-en.xhtml I don't think that link exists...
For Sale: HP3586B Frequency selective level meter VLF receiver 50Hz to 32.5MHz , This unit has the high stability oscillator and is excellent condition. No...
Main reason why I don't do much listening cause of living in a apartment. I May I have to get support on building a b-field receiver circuit like I did in...

October 05, 2010 : 0606:09 UTC Here is another sprite cluster capture. Again at VHF. Synchronous "click-click" noted. No forward scatter VHF "ping" noted...
Dear VLF enthusiasts, A short documentary that I made about Steve McGreevy, founder of spaceweathersounds.com <http://spaceweathersounds.com/> , called ...
Although I was not recording at VLF this night here is a sprite capture with precise UTC timing so that anyone recording VLF/ELF/ULF can check their data if...
