Hi Alexei,

we usually switch the cardioid to east-north-east for a few hours during our late afternoon and early evening. But later at night, we like to turn it to the west to optimize for VO1NA and other potential TA stations. But it also depends on noise and lightning conditions as we try to steer arway from the QRN. And sometimes we forget to switch at all... Currently the F/B ratio is anyway not very good, mostly because of the different E-field sensitivity in the winter time.

Hi Sergey, probably SM6BGP in WSPR. He appears regularly also at DL0AO:

 2023-12-16 10:40     SM6BGP     0.137412     -13     0     JO67     1     DL0AO     JN59vk     897     185     W-2
 2023-12-16 10:20     SM6BGP     0.137412     -14     0     JO67     1     DL0AO     JN59vk     897     185     W-2

We are starting to travel today, so there will be no LF transmissions from DF6NM until mid of next week.

73 and good luck,
Markus

Thank you Andrei for mentioning the reception. My radiated power is almost 20 dB weaker than DL7NN. Last week he got good FW5 reports from VK6MJM and VK2AN. So I thought I could have a chance to reach Australia in FW30, and transmitted a few times. Unfortunately my dream did not yet come true.

Best 73,

Here's another small screenshot from my own colour-DF grabber. East is red and west is blue.

Looking at the lowest of the four FW5-tones from UA4AAV in a high-resolution spectrogram, we find a small diurnal drift of the carrier frequency (about 0.03 to 0.04 Hz). Is it caused by daily repeating temperature changes in the shack?
