WSPR decoding on a headless Raspberry Pi At last Sunday's ARNSW Home Brew group meeting, Peter, VK2EMU handed me a Raspberry Pi a USB audio dongle and my mission instructions to set up the Pi to decode and report WSPR spots in a headless configuration. The most popular is the WSPR decoder. For each month I download the complete WSPR database CSV file from wsprnet. This link goes to the WSPR spots page. The CSV files are too large to be used directly in Excel though, so I first break them up with the use of a little program called CSV Splitter from Polderij IT which can be downloaded for free. Configuring WSPR transmitter. This also creates “unknown” video blips that actually do correspond to a spot, but the character of the blip usually tells you whether or not an unknown is a mode of interest. WSPR-RX/TX-Station - R0AEK SDR SoftRock Ensemble RXTX + HDSDR + WSJT-X + PC on Intel Core 2 Duo CPU. Receiving stations with internet access automatically upload reception reports to a central database. WSPR-X User’s Guide Joe Taylor, K1JT Revision date: March 19, 2013 Overview WSPR-X is an experimental version of WSPR that offers an optional slow mode with 15-minute T/R sequences and 9 dB better sensitivity than the normal 2-minute mode.

This is consistent with previous results and with some of the better antennas I have tested:. The program can decode signals with S/N as low as -28 dB in a 2500 Hz bandwidth. It must be close enough because I've had WSPR spots at SNR levels down to -32 dB so the analog approach to generating WSPR works fine! I've had the transmitter running for almost 2 months now using this method of generating WSPR and stability has been fine. WSPR’s windows: • Rx Waterfall • Control panel and rx log. GoTo on WSPRnet. The lack of stations at intermediate distances may be because few are active on WSPR, but it “feels” like a single long hop, not unlike F2. You can plug your rig into your PC soundcard and use the WSPR software by K1JT to decode spots. Stations with internet access can automatically. org and upload a position report to aprs. Radio conditions have improved considerably since previous posts. Three techniques are examined: complete decode of WSPR stations by way of the KiwiSDR WSPR extension, use of the KiwiSDR to downconvert to an audio file which is decoded by a remote host, and for contrast a non-KiwiSDR path using an Apache Angelia SDR board. org is down or networking fails for whatever reason, the spots are not cached; essentially it is a one shot deal, either they get posted or the decodes are lost.
