Regarding the transmitter phase steps: As opposed to SpecLab's 1pps lock, the phase of a signal generator or DDS synthesizer will only be maintained if it is running continuously without any interruptions. I'm wondering if the discontinuities might be caused by temporary GPS outages during the day (jamming from North Korea? ;-), or perhaps intentional manipulations of generator frequency e.g. while checking antenna tuning.

Best 73,

Well I do love to multiplate the generator Markus :) I have been changing the frequency daily to check the tuning. I had no idea that would cause phase changes even as logical as that may seem. Computer timing is Dimension4 connected to tick.usno.navy.mil set at 49 min intervals.

No repeat transmission tonight but maybe tomorrow night. Wed night is out but maybe the same message again Thursday night I you wish.
