Hello Wolf! Good news: Today the GPS-module arrived. I'm not sure how long it will take me to make it work but soon I will transmit on a very stable QRG. That should make it much easier for Paul and
Gentleman! If really somebody else sent this mail on Mal's behalf, we must not ignore this issue but rather it is serious! To have an opinion and to state it, is basically a good thing, even it is no
Roger! Most probably, I will transmit tomorrow starting between 8:00 and 9:00z. I will be slightly below 8970 at 8969.95 (+/- 0.03Hz) and announce more details tomorrow. 73 OE3GHB Gerhard Am Donnerst
Hello Daniele, group! I will fire up later slightly below 8970. Ossi is already transmitting. 73 OE3GHB Gerhard Am Sonntag, den 23.01.2011, 00:54 -0800 schrieb Daniele Tincani:
Hello Lubos! Yes, it's me. I'm trying to optimise my setup. In average I'm running abt. 150W antenna input at roughly 500mA antenna current. I think I will transmit for one more hour today but I plan
Hello Lubos! Thank you very much for the capture, nice to know that some are watching. Both, Ossi and I put lot of effort and work into this project and the more we appreciate any report. 73 es tnx O
Hi Markus! I think the carrier at 8969.995 was also sent by Ossi. In the moment he's calibrating his DDS, trying to reach 8970 as exactly as possible. For sure it wasn't me!!!! 73 Gerhard Am Dienstag
Mal! I and all others who actually are TXing on VLF, put a lot of work and effort in this project. We are constantly improving our setup. In addition we even have the chance now to observe propagatio
Daniele! Ossi is transmitting on 8970.02 and I'm transmitting on 8969.98....so either you have a frequency offset in your RX and receive one of us...or it is a locally generated signal. 73 OE3GHB Ger
Hi! Since about 11:00z, I'm using DHO38 as a reference for my carrier on 8969.98. As it can be seen on your grabber, frequency is stable. I'm using a 3,5mH surplus DCF77-Ferrite rod (20cm by 1cm) res
Andrey, LF! Thank you very much for this hint. I would be glad to have a trace from JA7NI on my grabber because it shows that all the work I put into this project makes sense in the end. Meanwhile JA
Hi Stefan and group! In the moment I'm running on GPS-Sync and will switch to DHO38-Lock in a few minutes. I'm curious about the stability. Antenna-current is as usual about 550-580mA. Beside my plan
Hi Lubos! I was "fighting" with the Digimode-Terminal of Spectrum Lab trying to send DFCW5000. That's why the QRG changed. Currently I switched back to a constant carrier on 8969.97 73 es tnx OE3GHB
Hello Eddie, group! Unfortunately it was not my signal you observed around 8969.99 but it was OE5ODL, Ossi. He managed to increase the antenna current by some changes to the loading coil and so his r
Hello Roger! I wasn't active today. I plan to radiate a signal on my "usual" QRG 8969.98 tomorrow during the day. 73 OE3GHB Gerhard Am Freitag, den 04.03.2011, 17:29 +0000 schrieb Roger Lapthorn:
Mal and group! "A couple of Hz"....is way too much off for seriously transmitting on VLF at low speeds. And low speeds are mostly required to detect the signal. A drift of 100mHz is the minimum requi
