Hi Steinar, Maybe I can help with that ... first of all, can you see the DHO38 signal as a 'hump' in the spectrum, center 23.4 kHz, with a few sidebands (caused by the MSK modulation) ? The MSK signa
Thank you Jim for recording and reporting! Much apprechiated. Do you remember your first detection of my signal and what the SNR and FFT bin width was? Would be interesting to compare the levels and
VLF, I'm now running 350W into the system and get about 0.8 A antenna current. Strong audible partial discharges occurr on a parallel fixed plate capacitor, spaced by 3 cola bottles (0.33l ;-) ). At

Thanks Steinar, But it will be a first pre-test, i may not get the maximum strength that i want but we'll see. How do you receive 8970 Hz on the software side? Do you have a "DFCW-6000.usr" for the S

The frequency is still a bit unstable since i took the DDS VFO which is more comfortable to find the resonance. I will now try to slightly QRO and then apply a fiber optic cable carrying the GPS loc
Stefan No, I'm afraid not but I've made some changes on my antenna system here. If you are able to run another hour, then I will try to copy you. la5vna S Den 27.11.2011 14:51, skrev Stefan Schä
Dear Stefan, LF Group, I wasn't at home during most of your transmission of Saturday/Sunday, but while I was out the RX detected your signal between about 0200 and 1000utc on Sunday at 8970.05Hz. The
Hello Roger, If i can set up the system without any problem then i will send a long carrier first and then i wait for some reports. Depending on what people can receive i will then go on to DFCW-600
FB Stefan We still have a big lack of sunshine so the Grabber is going on now with battery on float charger which I will remove in the morning. Good luck. hope the WX holds out. Eddie On 25/11/2011 1

Steinar When starting my grabber Stefan and Chris thought me some tricks: “and use the sample rate detector to lock your sound card to a stable signal” That helps if you are using the 600
Hello Stefan, VLF! I am looking forward to see your signal on my VLF Apollo grabber! You are right, that a noise is low. This effect has been very good visible on the last day picture, for example. W
