Here are two spectrograms showing traces of positive and negative decodes in WSPR-15.

Somehow there seems to be a time difference of 5 minutes in the spectrogram's time marker, probably coming from the setup process.

The lowest decodes SNR, here -38 dB, looks quite weak! I would have thought that it looks stronger. So maybe WSPR-15 is a bit more sensitive than i expected. Comments welcome.

LF,

I've added a temporary grabber window to the YV grabber, http= ://dl.dropbox.com/u/74746618/LF/YV7MAE_LF_Grabber.html which displays the WSPR-15 LF range. The spectrogram uses the same scroll rate and FFT settings as the typical QRSS-60 grabber windows.
The idea is to compare the SNR indicated by WSPR-15 to the subjective visual SNR. Of course the RF energy is spread out to a few FFT bins, so the brightness or SNR must be lower compared to a QRSS trace. But anyway it will be interesting and give some idea about the performance of WSPR-15 compared to QRSS-60 or DFCW-90.
