Thread-topic: LF: Re: FR5ZX on MF WSPR

Being on holiday in I seemed to have missed some nice propagation on 472kHz.

Just a thought (or 2):

- With dropping solar activity it is likely that propagation will improve the coming years.

- The distance Europe-FR is almost the same as Europe-ZS, where we could get a much larger audience.

Somewhat belated, here's a simple SNR plot of Michel's exceptional receptions last Saturday night. We can see that there was significant QSB but also some shorter steady periods, but it remains questionable whether using WSPR-15 would provide the expected 9 dB gain.
All the best,
Markus (DF6NM)

Hi Fausto,

Normal CW would have been possible last night! There were 90 decodes by FR5ZX last night. The best reports from last night are:

You know, a few weeks back i've tested the readability of a signal at -6 dB and -16 dB. -6 dB was fine for a normal speed (100 Bpm) CW QSO. -16 dB was barely audible, not fine for a QSO, maybe a call can be copied when repeated a few times. So i think that -12 dB should be fine for a QSO at 60 Bpm and some concentration... But it was just a short moment within 4 hours. Not sure if someone want to call CQ for such a long time to make a "599tu" QSO then :-)

73, Stefan

PS: Could someone provide more statistical overview of last nights results?

Hi Stefan,
-14 dB !!!
Virtually with 10 dB extra power you would get an audible CW 9000 Km WOW.
