Statics doesn't seem to affect wspr too much at this level of signal. I was using a 2x2m one turn loop tuned to 500 kHz and a dedicated 500 kHz SDR receiver. I/Q conversion to base band is performed by SpectrumLab. You may notice a change in your reported frequency. I modified the OL frequency (SpectrumLab) by only one hertz to correct a wrong value, but infortunately the FFT size still needs to be increased to get a better resolution (the fft resolution reported by SL is 1,4648 Hz !) The code of the 137 kHz transceiver is now successfully modified to send a WSPR beacon, and I plan to do real operation on saterday 17 at the local radioclub (depends on the good or bad weather though) 2154 38 5 1.8 0.503512 M0BMU IO91 30 2202 37 5 1.7 0.503512 M0BMU IO91 30 2206 38 6 1.8 0.503512 M0BMU IO91 30 2210 35 4 1.8 0.503512 M0BMU IO91 30 2214 33 1 1.8 0.503512 M0BMU IO91 30 2222 33 1 1.8 0.503512 M0BMU IO91 30 2226 35 4 1.9 0.503512 M0BMU IO91 30 2232 31 -1 1.8 0.503512 M0BMU IO91 30 2238 29 -2 1.9 0.503512 M0BMU IO91 30 2246 31 -1 1.8 0.503512 M0BMU IO91 30 2252 32 1 1.9 0.503512 M0BMU IO91 30 2258 31 0 1.8 0.503512 M0BMU IO91 30 2302 35 4 1.9 0.503512 M0BMU IO91 30 2310 30 -1 1.8 0.503512 M0BMU IO91 30 2318 27 -3 1.9 0.503512 M0BMU IO91 30 2324 39 8 1.9 0.503512 M0BMU IO91 30 2328 34 2 1.8 0.503512 M0BMU IO91 30 2332 30 0 1.9 0.503512 M0BMU IO91 30 2336 31 0 1.9 0.503512 M0BMU IO91 30 2342 34 4 1.9 0.503512 M0BMU IO91 30 2348 30 0 1.9 0.503512 M0BMU IO91 30 2352 32 1 1.9 0.503512 M0BMU IO91 30 2358 33 3 2.0 0.503509 M0BMU IO91 30 0004 25 -5 1.9 0.503509 M0BMU IO91 30 0012 37 5 2.0 0.503509 M0BMU IO91 30 0020 32 1 2.0 0.503509 M0BMU IO91 30 0028 39 7 2.1 0.503509 M0BMU IO91 30 0036 38 7 1.5 0.503509 M0BMU IO91 30 0040 33 2 1.5 0.503509 M0BMU IO91 30 73, Michel, f5wk
