Hello Markus and all, I'm trying to reply to Alex's call around 137.540 kHz as suggested by him to ship the qrm. But seems that my very weak signal is not received. Thanks Alex for your efforts! Btw
Good evening LF, Tonight i'm running some local test with WSQ mode on 137.600 kHz (lowest freq). Maybe some station in the range can catch my signal? Test will end at 22.00Z 73 all Domenico (iz7slz).
that's exactly what I did too, with same results: wspr-2 running and uploading fine, no chance to test -15 due to lack of signals. But if signals had been present on both bands, wouldn't both instan
Good day group, Andy here's my receptions of your WSPR-15 signals in JN80NU. Sorry pc was not on-line so the spots were not uploaded in the net. I have uploaded them just few minutes ago. 2045 -2
Good day all, i did a similar test on may 27 night by transmitting, in close time interval, some WSPR-2 and WSPR-15 sequences. For Markus statistics, these are results: Timestamp Call MHz SNR Drift G

Hello Group, good reception of SAQ in JN80 (QRB abt 2100 km) notwithstanding the sferics. This was the QTC: VVV VVV VVV DE SAQ SAQ SAQ CQ CQ DE SAQ SAQ SAQ <BT> THIS IS GRIMETON RADIO/SAQ IN A TRANSM
Hello LF, Roman thanks for your report. Tx conditions for my yesterday test: Antenna inverted-L (h=8 meter) with cage arrangement. Power out =100 W. Tx keyed by SpectrumLab. All the best. 73, Domenic
Hello Andy, all thanks for the info and for the activity. I'm at your S-E direction so maybe i have some possibility to catch your signal. So i will listen in WSPR2 and OP8. 73 and GL Domenico, iz7sl
Hello LF, I am pleased to report a successful "Coherent BPSK" QSO between DF6NM and IZ7SLZ on LF using EbNaut program of Paul Nicholson. QSO took place in the night between Friday 2015-09-18 and Satu
Hello Andy, all thanks for interesting at this test. Yes, Spectrum Lab is the right program to manage the audio from receiver also in this case. The SL configuration used in LF_EbNaut experiment bas
Hello LF and all, here's my "2 cents" about coherent-bpsk transmit point of view. I will briefly describe the setup used by me during the tests and QSO with DF6NM. I have employed an old analog SSB E

Hi Paul, Markus and all, in this weekend i have made a simple modification at my LF TX to improve frequency stability. I have phase-locked the 10 MHz OCXO of the exciter with the 10 kHz signal coming
Good evening Paul, Markus and all, thank you for your updates. I will start some EbNaut transmission at 22.00 each hour and hope that Paul can make some measurement on my signal . Qrg is 137502.24 Hz
Hi all, Markus, thank you for the report. The small difference in QRG is due probably to the fact that i'm not using resample now. Transmission of 6 char./3s with 10 W will start in few seconds. GL D
No Markus, i'm not sure now ! The power reduction that i'm now using is the built-in circuit of the PA (ex-marine reserve transmitter): one relais takes the output of the driver stage and brings it d
In fact, impedance transformer was by-passed also. Now it is fixed. I have driver stage to the variometer through the transformer. Neon lamp lights up more ! Please check next transmission Thank you.
