Hi Edgar, no I don't think so. It's not a very high peak (12 dB), too low in freq (-18 mHz), and probably too late for propagation (13:45 UT). Best 73, Markus --Ursprüngliche Mitteilung-- Von: edgar
Hi Andy, presumably the digital 1 kHz-to-baseband conversion is done in an FPGA or DSP in realtime. The associated periodic processing activity or register content could lead to a 1 kHz component rad
Attached is the continuation of the carrier plot until 16:24 UT today. The continuous phase plot has been centered 0.12 mHz below nominal, but it may have suffered from a couple of cycle slips. Yes t
Hi Joe, Paul, here's my three day's worth... Going from 2 to 5 minute averaging seemed to produce fewer cycle slips, and the best-fit average frequency was now around -0.144 mHz. As my calibration is
Yes Mike, VK2ALF was apparently listening on 30m (10.14 MHz). All the best, Markus (DF6NM) --Ursprüngliche Mitteilung-- Von: Mike Dennison <[email protected]> An: rsgb_lf_group <rsgb_lf_grou
Laurence, this may be a long shot but I've started WSPR-15 receive 137.6 to .625 kHz. 73, Markus (DF6NM) From: [email protected] Laurence KL7 L Sent: Sunday, December 13, 2015 10:04 PM T
Yes Paul, that sounds like a very reasonable proposal. Joe's OCXO is obviously stable enough for the task, all that's needed there is a different frequency word for the DDS. And considering the anten
Hi Laurence, I've shifted the zoomed section of the 438 uHz spectrogram 1 Hz down to 137776 but nil so far. Well I think you mentioned that your LF transmit loop is not pointing towards Europe, but I
Luis, thanks a lot for sharing this information. We can all wish Michel good luck in the process of getting on air. Reunion in VLF ! :-) ... well that's a natural match - for many years, La Reunion h
Hi Laurence, might be from Israel (same as 26.0 kHz): https://groups.yahoo.com/neo/groups/VLF_Group/conversations/topics/23717 73 and happy 2016! Markus (DF6NM) --Ursprüngliche Mitteilung-- Von: Laur
"HNY" from UW8SM, using slow sequential-multitone Hell for a QRSS-30 spectrogram. Try scaling the screenshot 20% horizontal x 200% vertical. Best 73, Markus --Ursprüngliche Mitteilung-- Von: DK7FC <s
Hartmut, many thanks for the fine report! The signal was on air from 20:00 to 21:40 with about 10 mW ERP, warming up the frequency for John ;-) All the best, Markus --Ursprüngliche Mitteilung-- Von:
Hi Riccardo, the strong carrier (12 UT yesterday to 1 UT today) sure looks like an intentionally generated amateur signal. But it seems much too strong to have come from DJ8WX in North Germany. Do yo
Hi Riccardo, thanks for the info. Sorry, I'm not registered on Facebook so couldn't see that picture. At the bottom of your grabber page there is another interesting trace with a blue ellipse around
Those gaps occur at +-30 Hz from each 200 Hz multiple, i.e. 137.77, 137.63, 137.57, 137.43, 137.37 kHz etc. They are only a few Hz wide and apparently caused by symmetries in the 200 baud, 2x170 Hz s
