Antenna current is now 0.28 A with a bit of s; /rsgb_lf_group-archives/html/rsgb_lf_group/2016-01/msg00324.html (10,729 bytes)

Using EbNaut, 15 dB SNR in 0.63 mHz noise bandwidth should support about 12 characters per hour. But this will probably have to wait until you have finished your loca; /rsgb_lf_group-archives/html/rsgb_lf_group/2016-01/msg00327.html (13,557 bytes)

S/N 16.3 dB in 1/10800 Hz using E and H, 11.0 dB using H only. Amazing how well a few uW does at a range of 1028 km. -- Paul Nicholson --; /rsgb_lf_group-archives/html/rsgb_lf_group/2016-01/msg00328.html (9,594 bytes)

Good timing, good oscillator, wise choice of symbol length, and that widget you use to maintain the phase of the antenna current probably helps a; /rsgb_lf_group-archives/html/rsgb_lf_group/2016-01/msg00351.html (11,020 bytes)
