-40 dB.    Minus ten thousand times the noise level  -  ain't technology great?

I'm more amazed that you were copying XKO.  The signal was from a SBL-3
mixer, filtered then amplified by 10 db.  I measured +6.8 dBm  going to
the antenna with a HP-436A power meter.  Anyone care to estimate the ERP
in micro-watts?  One decode you got shows a SNR of -40, best was -25.
Last decode was a 0600 so I thought maybe you had shut down but this
morning I saw the problem.  Antenna coil is iced over and it way out of
tune.
