Constant reference phase. Carrier S/N 15.5 dB in 25.4 uHz. -64.4 dB in 2500 Hz after sferic blanking. I was expecting to decode at about +1.2dB based on yesterday's S/N ratio. Today must have been a little noisier and I had to use a more aggressive blanker setting to maximise the Eb/N0. Uwe wrote: > EbNaut RX V0,4d tells me âError: Not enough memory (trellis)â. You'll need a spare 22 GByte of RAM to decode this one. -- Paul Nicholson --
