Hi Domenico, no, not me. The strong signal in https://dl.dropboxusercontent.com/sh/qx230q4lxerepeo/AAD7lpktx1thN2B5rIggKW52a/argo0034.jpg is probably IQ2MI from Milano sending QRSS-3. To help save th
Hi Stefan, good to see the remote station working nicely now. ...yes you do ;-) There is a slight frequency offset in the remote grabber which had put me out of your QRSS-30 band. I now switched to m
Hi Stefan, it looks like signals are consistently better on your remote receiver, perhaps around 6 dB or something in that ballpark. So it seems that all your work is finally paying off! I'm looking
Hi Stefan, since last night your two receivers have been operating without interruption, allowing to compare results from your two grabbers. - WSPR: Last night, 21 of my low-power WSPR transmissions
Stefan, just tried some more WSPR between 12:44 and 13 UT, but with the current intense QRN there's just no chance. In the morning, there were only sparse flashes (maybe 1 to 5 per WSPR sequence), wh
Revisiting the topic... My ERP calculation was erroneous by a factor of ten (looks like I can no longer do without a calculator). It should be radiated power = 0.0256 * 160 = 4 microwatts or -24 dBm
Hi Wolf, Stefan, In the presence of strong in-band signals, there's probably a fundamental tradeoff regarding the choice of noiseblanker ramp timing: We want fast ramps to achieve effective blanking
The two cheaper sound dongles from "vendor B" finally arrived today. They had been sent from an address in Berlin although there was a link to "softsilkroad.com" stamped on the parcel. As predicted b
Waking up early this morning, I took a look at Stefan's garden grabber http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_remote_Grabber.html and was greeted by a fascinating display on his VLF pane
Hi Stefan, LF, we're not just playing around... I would rather consider this an original scientific experiment, perhaps worth proposing as an research project in environmental physics ;-) Frequency s

Friday night (July 24/25) was stunning. Coming home from a beer after local midnight, I noticed spectacular VLF spherics resonances on the DK7FC remote garden grabber (screenshot http://df6nm.bplaced
Thanks to Steve and Stan for kindly passing on this information. I have reactivated the two slots for Wildwood, and added a new one for Dana to the right side of my Loran-C monitor: http://df6nm.de/L
Hi Dave, after a very pleasant CW QSO with DK1IS, at 9 UT I did see some blue traces on 136.5 which might have been you. But currently not strong here enough for aural copy. Will try some DFCW around
Dear Dave, thanks very much for this nice QSO! Just like in the "old days" ;-) Your signal is well visible, and even faintly audible between the DCF39 splatters. Best 73, Markus (DF6NM) From: daveyxm
Mike, just happened to catch you calling DK1IS - currently "M" here, but summer QRN already increasing. Best 73, Markus (DF6NM) From: DK1IS Sent: Sunday, August 09, 2015 12:19 PM To: rsgb_lf_group@bl

Hi Roman, maybe the wrong idea was to NOT watch the Eu slot during a European activity day? Best 73, Markus (DF6NM) --Ursprüngliche Mitteilung-- Von: Roman <[email protected]> An: rsgb_lf_group <rsgb_
During the night August 6/7, the Loran signal from Wildwood (GRI 8970 M and S) was received again in Nuernberg / Germany. Using five minute averaging, SNR was up to about 28 dB (power added sum of al
A few weeks ago, the IARU EMC coordinator, Thilo Kootz, made me aware of an European directive "Decision 2006/771/EC on harmonisation of the radio spectrum for use by short-range devices...", see htt
