My main antenna is under repairs. Too hot outside here (around 35 degrees) even in the evening time. At moment receiver is working with a 5 meter whip that does not perform like the main antenna. Also big noise comes from nearby thunderstorms (mostly yesterday) I think that this is the reason of the missing decodes.

Please inform the time of your missed transmissions. I will try a deep investigations using also SL /opds recordings. 73 all Domenico, IZ7SLZ On 27 July 2017 at 17:52, DK7FC wrote: > Hello Domenico, LF, > > Yesterday and today i sent a few messages to your grabber but got no > decode.

Hello Stefan,
= thanks for the report.

My main antenna is under repairs. Too h= ot outside here (around 35 degrees)=C2=A0 even in the evening time.

=
At moment receiver is working with a 5 meter whip that does not perfo= rm like the main antenna. Also big noise comes from nearby thunderstorms (m= ostly yesterday)

I think that this is the reason of the missin= g decodes. BTW i also checked status of all linux programs and they are run= ning ok :

- vtcard and vttime
- gpds + ntpd
=
- vtresample + vtwrite

btw i will perform a pc resta= rt now.

Please inform the time of your missed = transmissions. I will try a deep investigations using also SL
/opds reco= rdings.

Hello Domenico, LF= ,

Yesterday and today i sent a few messages to your grabber but got no decode= . The SNR should have been fine. I checked if everything is ok on my side, = it should be.
Is it maybe on your side?
Maybe Riccardo can check if he can decode the message from today 10 UTC? On my own RX i can decode the message with some frequency offset (-0.01) be= cause the 10 kHz ref signal (still the old method here on LF RX) is overloa= ded, so there is no sample rate correction when i'm on air on LF. But t= he timing seemed to be ok at least!

Hello Stefan and LF,

Here is the report of recent EbNaut DK7FC's transmission on LF.

It is amazing how to get a decode using this mode over 1100 km in daytime o= n summer=C2=A0 and in my urban receiving location plagued with electrical n= oise at this hour.

Mni compliment Stefan for your very coherent signal and regarding your VLF = encouraging words, i confirm that soon i will try to use this linux setup o= n "dreamer's" band. I need to built another location for rece= iving outside the city. High QRN here in my urban shack for 8 kHz and below= .
Aunt Melina is happy to host me and my radios in her farm=C2=A0 so i'm = building a duplicate of the setup in use here for the installation at AMF.<= br>

Gost32 helped me to clone the ubuntu pc. The 2nd GPS cabling is in progress= .

Most probably i will complete the VLF rx=C2=A0 in mid of August during my v= acation.

Thanks again for your signal Stefan.
