Content preview: Congrats on your grabber, Markus. The output was less than 5 watts, 0.4 amps RF so this is a true QRP TA reception. It almost appears as if the QRP path is a bit to the south by the greenish colour. Hartmut's grabber showed fairly consistent copy until about 0745 and TF3HZ was good until the QRM at 1000.
