thanks for suggestions.
Tonight I'll suspend the grabber session to implement the 1pps GPS.
This was just a testing to see if I've problem with web upload, pc, etc... At the moment I'm using an old notebook that gives me the possibility to run a couple of SL sessions without wasting much energy.
Ok for filtering the reception, this will improve for sure the signal quality.
Unfortunately, also living in a small rural suburb, I've a lot of noise for some years now "thanks" to new neighbor (LED lights), so I'm looking to install all system in a quieter place that can be easily approachable by a 5 ghz LAN, may be I could get ideas from your remote station, HI.
I know that IW4DXW Riccardo and IK7SLZ Domenico are warming up for VLF transmission. Rick transmitted for a while yesterday night but some capacitors problem impede a good system performance, so We are looking for new C's. I'm in the center between the two OM so could be a good place for RX test.
Not so many Italian HAM in VLF and LF now.
Thanks for now!

That's nice, very interesting and the configuration looks quite optimal.
Are you already using the noise blanker and band pass filter centered at 8.27 kHz?
We are in 940 km distance. That could be possible. But you would need a 47 uHz window to see something i think.
You wrote you're using ICV as the reference. In the past i have heared that ICV is not so stable (relative to other msk transmitters in the band). Do you have a stereo soundcard and could use the 1 pps option when using a cheap GPS module?
Any discussions on Italian forums regarding stations preparing for transmissions?
