Joe VO1NA on 8270.0075Hz , Stefan DK7FC on 8270.0Hz, Uwe DJ8WX on 8269.996Hz. And maybe Riccardo IW4DXW on 8270.003Hz
VO1NA on 8270Hz received in Warsaw
Since a few days one can see a faint line on 8270.0075Hz. This is transmitted by Joe VO1NA from Canada. The distance to Warsaw is 5100km!

A faster grabber for 17470.1Hz
Stefan DK7FC’s signal on 17470.1Hz is so strong, that i could make a faster grabber:
Temporary SQ5BPF 17.4701Hz 556uHz grabber for Stefan DK7FC’s tests
Radiostacja Babicka wpisana do rejestru zabytków
The remains of the Transatlantic Radiostation in Babice/Poland were added to the Register of objects of cultural heritage in Poland. This was the sister station of SAQ.
This was accomplished by Stowarzyszenie Park Kulturowy Transatlantycka Radiotelegraficzna Centrala Nadawcza Association.
