Hello group! Ossi will most probably transmit again this night. His QRG will be 8969.98 (+/-). He will start between 23z and 0z and leave the TX running until the morning or even longer. I have set u
Hello group! Below, you'll find a copy of the E-mail conversation between Paul and me regarding my TX experiments today. Hello Paul! Nice to hear back from you and thank you very much for observing a
Eddie! Yep, you could be right about yesterdays signal. If you want to know about Ossi's activity you can check out www.langwelle.at . This is Ossi's grabber which is roughly 10km away from his QTH.
Hello group! I started my TX on 08:47 at a QRG of 8969.98. Antenna current is 550mA but maybe radiated power is a bit more today because I managed to lift the coil from the ground about one meter. Th
Hello group! My TX is on from now until tomorrow morning. Power: 9A at 14V = 270-300mA antenna-current. QRG: 8969.99 locked to DHO38. Any reports welcome! 73 OE3GHB Gerhard
Mal! It's a 0.6mm enamel wire. 1mm diameter would work fine and of course reduce the losses significantly. Just keep in mind, that the overall length of the coil will increase with thicker wire. My c
Eddi! Thank you for your feedback. Even a negative report is useful sometimes. At least it gives me a hint on my next goal! 73 es tnx Gerhard Am Sonntag, den 20.03.2011, 07:53 +0000 schrieb qrss@talk
Hello group! I just fired up my VLF-TX with reduced power for a overnight session. The QRG is 8969.98, antenna current roughly 350mA. Input power is 13,8V at 10A. It is very windy here and I hope eve
Hello Stefan! No, it wasn't me transmitting on 8969.98 today, it was Ossi. Because he uses a DDS with the smallest step of 0.1Hz and the temperature is warmer than some weeks ago, his QRG went down.
Mal! I completely understand and respect your statement. A few month ago, QRSS60 or anything slower was out of my imagination but meanwhile I'm happy if a sign of my signal is seen at much lower spee
Hello Uwe and welcome on board! Congratulations to your success. I wondered about the signal on my grabber and asked Stefan if he is aware of any experiments going on down there. But like me he had n
Hello Mal, group! As far as I know, Markus and Ossi both use multi layer coils. They are very compact but with the known problems regarding insulation. I think Markus meanwhile has also a single-laye
Eddie, Markus and group! The long bright line was indeed caused by a local test. Eddie: My grabber is locked to GQD and should display the QRG very accurately! So what you see is what you get! Ossi d
Henny! There's also a nice trace on Pauls grabber: http://abelian.org/vlf/fbins.shtml 73 Gerhard Am Sonntag, den 27.03.2011, 15:32 +0200 schrieb henny van elst:
Hello Uwe! Regarding to my experience, the 40kV are real. Considering the high power (anf thus current) you are running, the voltage would be much higher on my 550mH coil. 550mh = 31kOhm at 9000Hz =

Hello VLF! I just fired up my VLF TX at 8969.96, DHO38 locked. Currently running 500mA antenna current but I have to reduce to 400 later when my neighbor comes home. Any reports welcome. 73 OE3GHB Ge
