Hello Paul,

A new week where we can push the limits! :-)

Well, let's try that:

f = 6470.100000 Hz
Start time: 25.Apr.2017   06:00:03.20
Symbol period: 4.3 s
Characters: 100
CRC bits: 8
Coding 16K21A
Duration: 12h, 0m, 6s
Antenna current: 460 mA



73, Stefan

carrier Eb/N0: 17.7 dB
carrier S/N: 28.32 dB in 24.4 uHz
carrier phase: 67.2 degrees

carrier Eb/N0: 17.6 dB
carrier S/N: 28.17 dB in 24.4 uHz
carrier phase: 63.4 degrees

Excellent repeatability of the two transmissions.
Stacking the two days gives:

carrier Eb/N0: 20.7 dB
carrier S/N: 31.25 dB in 24.4 uHz
carrier phase: 65.3 degrees
