fb.. here too (630 m only, I won't blow the dust off the old 136 kHz rig)... hoping wx / QRN permits. Won't be active on sunday, only on saturday night. 73, Wolf DL4YHF / DF0WD in JO42FD . Am 08.08.2
Strange indeed, no mails from the black sheep here for two days, and then suddenly over ten on friday (when i was not qrv, been visiting the DNAT in Bad Bentheim). Chris : I have already put down the

Hi all, If it helps, I could add all necessary settings in the "Quick Settings" menu, including the decimators, SR calibration, etc etc. But for the timestamps in the I/Q recordings, it's very handy
Sounds like an application for one of those Cortex-M development boards with built-in fast multi-channel ADCs, like the one Alberto recently mentioned here. I have a stm32f429-"discovery" board here.
Hi Stefan, If you don't find a ready solution, I could modify my 'ridiculously simple NTP client' for that purpose... 73, Wolf . Am 01.10.2015 um 23:01 schrieb DK7FC: Hi all, Does someone of you know
Oh yes Markus, a time-warp machine which spits out the signal before it has even entered the receiver... contesters and rare-bird-hunters on shortwave would pay a fortune for such a program. Call the

Hi Andy, yes of course. Feel free to use it, modify, distribute if (unfortunately Borland C is a bit out of fashion but I still love it). Beware of a pitfall with 'modern' windows: The good old 'SetS

Hello Chris, About RCDs tripped by RF : That's an interesting subject, even though I never experienced such a problem myself (no surprise since I mostly run QRP on any band). After discovering that t
Hello Andy, The wave files written by Spectrum Lab are indeed decimate I/Q pairs (camouflaged as a stereo wave file). Since the sampling rate (etc) in the header don't allow the required precision (n
Greetings all, There's a big range of signal levels during this QSO, is that normal for MF? The phase looks pretty steady on these short messages so I guess the amplitude should be too. Unfortunately
Greetings all, A configuration file and a detailed 'step-by-step' guide to configure SL is 'under construction', since I just finished another project. The main complexity is the need to compensate /
