Mal! Most probably I will be active again on VLF on Saturday, starting from about 8:00z. I will announce details later and it would be a pleasure to be if you could receive my signal. 73 OE3GHB Gerha
Lobos, Roger! Thank you both for listening. I think there is very little to no chance to be detected by you Roger but maybe it's worth the try. 20db over noise at 40km distance is very good and proba
Dear group! A few weeks ago, when I did my first test on VLF with my LF-station antenna, there was a thread dealing with acoustical noise generated when transmitting on VLF with about 100W. Meanwhile
Hello Markus and group! We...and I think I can speak for Ossi too in this way, are very satisfied to have reached this goal today. We both put a lot of work into this project and of course will conti
Hi Markus! Thank you for your answer the explaination. I switched down for 3mHz intentionally to be more apart from Ossi's signal at 8970.03 and to compensate a little upward drifting....it's getting
Dear Lubos, Jacek and Henny! Thank you all for your reports and the pictures enclosed. Today was very windy as usual, it was even a storm and so maybe not the best weather to do some tests. At least
Dear Markus and group! I'm not sure but probably on your grabber there's a nice propagation effect on VLF visible. I radiated all the time today with nearly constant power, except some 5 minutes brea
Dear group! I will have my TX running on 8969.97 (+/- 0.03) today. Locator is JN88hl, power to the antenna is abt. 150W I will start at about 8:30z. It is planned to keep the transmission up until th
Hello again! At about 12:30UT I disconnected the lightning protector again. At 500mA Antenna current the wires from the roof are at about 200V and the current to earth was measured at 60mA. I did thi
Hello Markus, group! Since about two weeks, there are transmissions from OE on VLF at a nearly daily schedule, either by Ossi or me, sometimes even both of us. We are both trying to improve the effic
Hello Lubos and group! Yes, I started at about 11UT. Yesterday at 12:45UT I reconnected the lightning protector of the house to ground but I couldn't see any difference on the plot you sent. So I gue
Hello Minto! Thank you for the reply. That confirms my thoughts. I will try to put another transistor in parallel soon. 73 es tnx OE3GHB Gerhard Am Donnerstag, den 13.01.2011, 21:15 +0100 schrieb Min
Hello group! I seem to be on 8969.98 drifting downwards. I have deactivated my VLF grabber because of the strong signal radiated. Conditions look better than yesterday and also locally the weather is
Hello group, Stefan! Yes, indeed I'm transmitting on about 8969,98 (8969,95 reading on my DDS) but I also can't believe that the signal displayed on your grabber is mine. To prove, I just changed QRG
Markus and group! The GPS module is already ordered to overcome the problems with stability. Beside the drift, my generator is producing some kind of jitter as well and so my signals are looking so f
Mal, group! Unfortunately I just had to stop my TX because it started snowing and the coil gets wet. Propagation seem to be better now than most of the day (at least to Stefan in 590km). My signal pe
Dear Markus and group! Conditions are definitely better compared to yesterday. I hope to get the GPS-receiver soon in order to draw a straight line on grabbers, that would make the signal even better
Hello Lubos and group! It wasn't planned but in the afternoon I had the chance to transmit for a while. The purpose was to test an normalize a new ampere-meter. My loading coil is located outside (on
Hello Andy, group! I had the VLF-TX running about 2 weeks ago, while I removed the lights for X-Mas decoration from a tree in the garden. One of the toploads is passing this tree straight above in a
Hello group! I started to transmit about an hour ago. See: http://members.aon.at/grabber/VLF Unfortunately my QRG will not be very stable and so some drifting can be expected. 73 OE3GHB Gerhard
