Decoded 'QRZ' at Cumiana (IK1QFK) with Eb/N0 = +0.4 dB, BER 41.6%; S/N -31.7 dB in 1Hz, -65.7 dB in 2.5kHz (after sferic blanking); List rank 5689, constant reference phase; Distance is 7173.4 km which is a new world record for VLF message decode and a record distance for EbNaut at all bands. Predicted Eb/N0 was +0.6 dB. Decoded via the live VLF stream from Renato's E-field receiver. These two stations already hold the record distance for carrier detection at VLF. This result extends that to a message decode. Signal data available in vlfrx-tools format: http://78.46.38.217/w4dex-171226-vlf15.vt Decode with vtraw -oa w4dex-171226-vlf15.vt | ebnaut -dp16K21A -r1 -S30 -k20 -N3 -v -PU -L500000 Congratulations to both stations for a great result. -- Paul Nicholson --
