Hi ULF,

Since 16:56 UTC  i'm running 180 mA antenna current on (2970 + 7/(24*3600)) Hz, i.e. on 2970.000081 Hz
With integer multiples of 1/(24*3600 sec), phase glitches at 0 UTC should be avoided (hopefully it works) and the small frequency offset is almost an integer multiple of the 5.06482 uHz FFT bin width spectrogram  (http://www.webalice.it/rromero/live_cumiana/last-LFtest_2970.jpg ). That one is running lovely since christmas time by Renato IK1QFK in 5 wavelength distance.

A first suspicious pixel may appear in 2 days, with some luck! :-)

The WX forecast is good for the weekend. I intend to run the transmission even in rain. The safety limit is set to - 30 mA.
This transmission consumes 3.1A * 25V DC input to the PA, not much.

It is planned to run it for one week, if all works well...

So there's a short break of my transmissions on 8270 Hz for that time.

73, Stefan

PS: Maybe someone can detect the carrier somewhere? Eddie, now that's your challenge, and Jecek!!!
