This morning I worked Kei, JI1BBN, on 15m PSK31 using 50W to the MFJ magnetic loop in the attic.
I heard several other DX stations on both the loop and the dipole, including DU3MEL in the Philippines whom I last worked in 2003, also on 15m. That was also the last time I worked Japan. Then I would only have been using QRP with my Elecraft K3, and the antenna would have been a horizontal loop of wire round the perimeter of the attic, with a 4:1 balun at the centre of one side, tuned using the K2 internal ATU.
What’s that about stealth antennas not working?
