Hi, again!
When we run CW-beacon and see reports from automatical skimmers, we can see reports from -1 dB to 30 dB and more. I never seen reports under -1 dB. But We know, that minimal SNR for CW decoding is -15 dB in 2500 Hz bandwidth KF6HI, http://kf6hi.net/radio/SNR.html.

We know about WSPR / CW advantage. It’s near 15 dB! When we run WSPR-beacon and see reports from automatical skimmers (WSPRNET), we can see reports typically from -1 dB to -30 dB. It’s agree KF6HI, http://kf6hi.net/radio/SNR.html.

Question Is where is -15 dB spots for CW in Reverse Beacon Network ?!
