It seems that Spec Lab is doing its thing well and I am grateful to Markus and Stefan for their help in getting it going.

The phase stability seems to be very good. It seems that Spec Lab is doing its thing well and I am grateful to Markus and Stefan for their help in getting it going. Lobbing the VLF photons across the pond and to the west will continue pending the wrath of Mother Nature -- a big storm is just about to start. There has been no EbNaut reception report from Canada yet. To change this, on hand are a raspi3 and vt tools working per Paul's instructions, neo7m, dk7fc vlf probe and battery pack. Is it possible plug the probe into the rasberry via a usb sound card to get a .vt file to decode? 73's Joe VO1NA On Sat, 30 Dec 2017, Paul Nicholson wrote: > > VO1NA wrote: > >> 28 Dec. 2100 utc, 16K21A, CRC-8, one character, >> 544 symbols, 1 minute each, >> 8270.0075 Hz. > > Measurements after two repeats of the new letter: > > Todmorden (3575 km) > ------------------- > > 28/29 Eb/N0 +11.4 dB, S/N -26.2 dB/1Hz, phase -175.0 *Decoded* > 29/30 Eb/N0 +13.7 dB, S/N -23.9 dB/1Hz, phase -168.4 *Decoded* > > Bielefeld (4301.5 km DL4YHF) > ---------------------------- > > 28/29 Eb/N0 -3.8 dB, S/N -41.4 dB/1Hz, phase 24.0; > 29/30 Eb/N0 +2.1 dB, S/N -35.4 dB/1Hz, phase 16.8 *Decoded* > > Warsaw (5096.6 km SQ5BPF) > ------------------------- > > 28/29 Eb/N0 -2.2 dB, S/N -39.7 dB/1Hz, phase -163.5; > 29/30 Eb/N0 -1.2 dB, S/N -38.8 dB/1Hz, phase 175.9; > > Stacked Eb/N0 +1.2dB *Decoded* > > Cumiana (4533.4 km IK1QFK) > -------------------------- > > 28/29 Eb/N0 -5.6 dB, S/N -43.2 dB/1Hz, phase 5.7; > 28/29 Eb/N0 -10.4 dB, S/N -48.0 dB/1Hz; > > Forest, VA (2415.3 km KE4RJQ) > ----------------------------- > > 28/29 Eb/N0 +3.7 dB, S/N -33.9 dB/1Hz, phase -33.0 *Decoded* > 29/30 Eb/N0 -5.0 dB, S/N -42.6 dB/1Hz, phase -35.3; > > On this occasion, the phase repeats very well. > > Hawley, TX (4240.3 km) > ---------------------- > > 28/29 Eb/N0 -7.5 dB, S/N -45.1 dB/1Hz, phase -160.5; > 29/30 Eb/N0 -6.2 dB, S/N -43.8 dB/1Hz, phase -105.8; > > -- > Paul Nicholson > -- > >
