Re: LF: Rx wspr 136khz tonight

[Pascal Deveaux <fr5dh@hotmail.com>]

Hello Luis and LF,

I use an icom ic-718. For the spectogram I try to do that. My loop was tuned to 474.2khz last night, I make the change to tune it to 136khz early next week.

Hi Pascal, LF

What is interesting about Teleswitch is to see the S/N of the carrier over noise. Don't know if there is a way

to decode the transmitted data

What kind of receiver are you using ?. You can feed the Audio to SpectrumLab and produce a spectrogram

to see the S/N and background noise in the band

hello Luis, LF,

I hear a teleswitch signal around 135khz (HGA22 ?) tonight. I do not know if I can decode it with fldigi ...

Hi Pascal, Alex, LF

 

May be the first step for Pascal in LF would be to detect the Teleswitch carriers

And then see which is the range of signals he can actually detect with his setup

 

https://www.sigidwiki.com/wiki/EFR_Teleswitch

 

We are very byassed to think in therms of northern hemisphere. But we are aproaching winter solstice

in south hemisphere. So, when will best conditions occur there ? About one month passed solstice ?

Said July/August ? Any chance for a VK detection in FR5 ?  At least in MF

Pascal,

I think you have no chance to RX anyone from Europe on WSPR2.

EA5DOM QRB=8783km   9A3KB QRB=8449km

Maybe DK7FC QRB=9096km in DFCW120 ?

I am ready to give a beacon for you in DFCW120 on 137.172 next night. How?

QRB=7777km

 

EB8ARZ QRB=9456km

Hello LF,
I will try to receive wspr beacon on 136khz tonight with my MF loop antenna.
