Betreff: VLF: A 300 char message?

Hi Paul,

Actually there is some time to try something during the daytime tomorrow. If you like, we could try a long 4K19A message. I prepared something:

f =3D 8270.1000 Hz
Start time: 04.November.2017  06:00:00 UTC (daily)
Symbol period: 5 s
Characters: 300
CRC bits: 16
Coding 4K19A
Duration: 10:11:20h
Antenna current: 600 mA

If you don't have time or would prefer to work on the hardware outside, just give me a short note, i would then stop the transmission.

73, Stefan
