Bonjour DK7FC, Le mercredi 30 juillet 2014 ŕ 16:57:47, DK7FC écrivait : Good gardening Stefan, hope that antenna plants will grow up rapidly Listening for your first signals right now ... 73 de Miche
This indicates , only 1 station decoded the signal so could be false Deep Search ?? more than 1 station , then spot is OK .. simple quality check using the decode time 23:17 136 LA3EQ de F5WK Op32 De
Hello Stefan, Now running the 40 µHz test under Linux/wine ... Antenna is a 10 meter vertical (no loop yet, too noisy at home) Hope to be ready for EbNaut in a few days. 73, Michel - f5wk Le vendredi
Thanks Stefan, VLF is a step toward LF, I'm planning to be "EbNaut ready" RX and TX for summer on 137 kHz It's too early to conclude about SpectrumLab on Linux/wine. It looks like higher resolutions
Hello Domenico, When recording EbNaut samples, do you have to compensate for the lag due to the huge decimation factor ? In other words is it ok or not, to start recording your H:00 transmission at H
Thanks a lot Domenico, now time to try to decode the files ... Michel - f5wk Hello Michel, The SL recorder function (thanks Wolf !) takes input from FFT and performs (i think) the inverse-FFT and all
Hi Domenico, LF, First decode, ever Frequency accuracy needs improvement, which requires the change of the two DDS of the RX/TX and an updated PIC firmware to support 48 bit FTW ... Michel - f5wk Le
Hi Domenico, LF, Nothing decoded so far ... I recall that last time only 2 transmissions were successfully decoded at 20:30 and 21:00 may be conditions have to improve. Anyway thanks for transmitting
Hallo Stefan, Looks promising, what sound card are you using and if you can read it, what is the audio codec chip ? I recently tried to replace the 12 MHz crystal of a CUA-202, but the onchip PLL of
Thanks Stefan for the info about your portable sound-card It uses the 24 bit Envy VT1620A, which looks nice for VLF and lower frequencies. I'll consider it for a portable natural VLF equipment (yes a
Hello Rik, Since a few years, CW is not different as the other modes, SSB, MGM and so on, no matter if the operator is holdinq a CW certicate or not. The only requirement is a CEPT license. HTH ! Mic
Hi, Big thanks to Domenico, Markus and Stefan for their successful decoding of my EbNaut transmissions. Ebnaut decoding is not an easy task especially with weak signal. I fear my GPSDO frequency was
Hi Markus, Yes I'm still transmitting with the same ERP as the other days. The antenna is brought to resonance by a series loading coil and impedance matching is performed by a tapped transformer. It
Hi Markus, Does this 3second time offset come from my side ? No intentional change to blame ! Could be a glitch with the VK16E GPS receiver - used only for NMEA, not for the GPSDO. 73, Michel - f5wk
Hi Markus, I agree that the 3 second time offset comes from my side. Now I have to understand the reason and make the appropriate correction. I returned home, and will concentrate on that problem. 73
Hi Clemens, It's been working here for several months on a Dell XPS W7Ultimate coreI7 Problem might come from an unwritable folder. You can specify the saved directory in the Audio Settings tabsheet.
