Hi Stefan
 
The idea is to keep it running 24= /7
 
Rx is a Perseus SDR using SDR-Rad= io software which can provide multiple VFOs into the Perseus bandwith and M= iniWhip antenna
Each VFO sends audio to different= applications using virtual audio cable. At this moment the bottleneck is t= he CPU
Running in a tiny Atom with 2GB r= am just let me use 3 VFOs and 3 SpectrumLab instances, plus a WSPRX decodie= ng MF WSPR-2
Adding an Opera decoder to the &q= uot;castle" fully collapses it ! :(
 
According to SDR-Radio the AGC is= off in all channels. But may be I don't have the right trimming in Spectru= mLab yet
The Rx is in a different QTH and = have problems to access it now remotely. Hope to get it fixed soon
 
I'm puzzled with the LF signal. I= t is a 38 minutes Tx which drifts initially and then stabilizes at 137.500<= /font>
During the day I can see partial = traces of the signal. Very clear during night. May be it is a local birdie = but very strange :-O

Hello Luis,

Your grabber is very nice! Will you let it run all the time or just sporadi= cally?
Which type of receiver are you using? Could it be that there is a AGC activ= e? What is the FFT resolution for the WSPR window? Maybe you can gain some = more sensitivity when going to 366 mHz or so.
