I guess we have to decide whether to go for the top or bottom of the band, I know some areas have problems with strong adjacent channel stuff. Would 135.85 be a good start? (I guess that's well out o
As someone who has just got interested in WSPR, I am surprised that this mode of personal beaconing has not become extremely popular on 137 and 500kHz. The bandwidth is only around 6Hz and the WSPR s
Dear Dave, LF Group, The problem with this part of the band is that it gets very severe QRM from SXV and the sidebands of HGA22, making it fairly useless for weak-signal reception in Europe. Last win
Alright, alright, let go of my arm. :-) Actually I though of looking when you said earlier but I have been doing other things. Using my 40m Doublet for 136KHz not too much plasma QRM yet. Reports via
You never know Stefan I might get a weak trace from you overnight! I'm too stupid to use Spec lab! I will try the Twente receiver but my internet is so very slow it might not work well enough. 73 de
hello Markus,all same kind of problem here with the wspr software.I switched my rx to cw with a narrow filter and 750HZ BFO offset.Decodes perfectly but no uploads to the database,allthough I could s
Hi Stefan, As you say we need DCF39 back again! I have only seen a couple of short transmissions from JA7NI. No other ham signals seen from JA or UA0 so far. I think the LF season here is still early
Oh yes, let us all make a MEGA activity on LF tonite, just like the last weekend on MF. That was really fine and impressing for all involved, i assume. Markus, Albert, Roland, Roger, Eddie, where are
Hello George, Thank you. Please tell me, did you get more experience about the best transmit times from EU to your location? Is JA7NI still transmitting for you or was it just a short test? I tried s
There is a very high LF/MF and digimode appliance operator density in the UK ;-) Also in Germany and the Netherlands and France. It looks like we (these countries) make the highest density of active
LF, I'm back from MF to LF and will run a WSPR (33%, normal, not slow) transmission on 137.45 kHz. Maybe some of the new receive stations that i saw on MF can be moved to LF by that :-) PWR is reduce
LF, Does someone join in on LF WSPR? There are many active RX stations! Eddie/G3ZJO, what about you? Your results have been good on MF. On LF the ERP will be 10 dB lower (ish) if the TX pwr is the sa
you? :-) ... 20 Hz above you ;-) Yesterday I finally got WSPR 2.11 working in IQ-mode with the FiFi-SDR on MF. Today I changed back to LF (which is 0.1355 MHz dial and 2000 Hz BFO here) and got fine
Hi George, There is no chance for you to display normal WSPR from me over that distance in a spectrogram. Maybe you could display WSPR-32 but this is still to optimistic i think. We really have to st
