That would be WOLF Mal that is a PSK system Its the audio to RF frequency conversion that is the big problem , unless you have a transverter , or a PIC-DDS vfo set up, the modes cannot be transmitted
Hi Terry, Jay, Joe, LF, Thank you Terry, you didn't miss any WSPR-32 transmission! :-) Also thanks to Jay for providing the useful data from the transatlantic path! Here the results are looking most
I doubt if WSPR is as good as OPERA taking all things into consideration. WSPR needs Linear PA at 35% efficiency. Opera works with an amplifier in class D or E at 90% efficiency. CW es QRS likewise w
Mal, You have the strongest signal in the UK. Yesterday, Martin/YV7MAE told me that he has managed to get a 6 dB improvement (i.e. noise reduction) with his E/H combiner. So there is a real chance to
It will be interesting to see the results in VK and LU compared to QRSS and CW I can see all these transmission traces on screen and could read if in QRSS mode without waiting for a Decode G3KEV -- O
Stefan I will TX the odd time when condx are optimum but not Beacon all night. I would like him to reply to me on 7 Mhz CW if he detects me. Most nights after dark I have good propagation to S.Americ
Stefan Screen grab showing decodes of FC and NM in WSPR32. I have now the correct Dial offset to report the correct QRG. But spots not showing on WSPRNet which is running again. Is there a filter in
Hi Terry, excellent! Your SpecLab screenshot caused some head scratching... Stefans transmission from 15 to 15:30 was decoded and is visible in the WSPR waterfall. But then, this same one is also vis

Terry, Chris, LF, Excellent! Thanks for the nice presentation of your results. It took some time until Markus and i understood what was happening (we have been on the phone and studied your screen gr
Hi Steinar, So what is wrong? Is the timing accurate? What is your LO frequency? 73, Stefan Am 23.09.2012 16:09, schrieb Steinar Aanesland: Hi Stefan I would very much give you a report, but even tho
Hi Stefan If you haven’t seen my messages yet then I’ll resend. For some reason, I never see any messages I post through BS unless someone responds. 73 Terry GW0EZY From: owner- rsgb_lf_g
Stefan My SDR was set with a “Dial” QRG = 135.164 and an audio B/W = 2kHz so your sig at 136.164 should be in the centre. Here is the wave file recorded with SL using the file menu-“
