Hmm, i just see that 18*3600/27=2400, so it should have started at
18:00:00 exactly. Odd. But we will see, maybe you have to play a bit
with the time offset +- a few seconds...|

Again, despite the stormy wx:
f = 8270.100000 Hz
Start time: 23.Feb.2017 17:59:58 UTC
Symbol period: 27 s
CRC bits: 15
Duration: 11h, 24m, 0s
Antenna current: 700 mA
Already running. Due to the 27s symbol length it was not possible to
start at 18:00:00 exactly. I checked the actual start on another PC. A
carrier was started 5 minutes before. The first phase switch appeared 2
seconds before the intended time, see attachment...
10 characters at 16K21A is the limit for my PC (Win7 32-bit 4 GB RAM).
I hope that yours is more modern. At least i know it from Paul, Jacek
and Alex :-)
For safety reasons i set the safety limit to 20 mA, i.e. the
transmission will be stopped if the antenna current falls below 680 mA
for 3 seconds.
