Re: LF: 2200m DX

Hello Paul, LF

here below some wspr-15 spots of your signal in Apulia, South-East Italy (JN80). QRB=6600 km

Hardware setup in use is the same as for LF EbNaut:

miniwhip antenna, JRC NRD-92M receiver, vlfrx-tools software + wspr-x (linux version). Location of the rx station is outside the city and it is a very quite site regarding QRM, unfortunatly there is no possibility, at moment, to get internet working for 'on-line' spotting.

To work WSPR, there is a bash file, based on vlfrx-tools (thanks Paul Nicholson)  that, every 2 and 15 minutes,  reads the raw audio from the Storage Hard drive, creates a wave file with the proper filename, and launches 'wsprd' for wspr-2 and wspr-15 decodes. This is the local log:

https://qsl.net/iz7slz/OPDS/WSPRDECODED_LF.TXT

The nice advantage of this method is that you can easly 'replay' the raw audio and try to obtain a missing decode by adjusting noise blanker settings. So i'm hoping to catch some of your wspr-2 transmissions; i will investigate soon...

Hello Stefan,

Very nice to see the reports from you. Just need a few more dB for
WSPR2. :-)

I will start to TX again at 20z.

73,
Paul
