I left the K3 and Fldigi spotting signals on the 40m band last night. The antenna was the MFJ magnetic loop in the attic. The screengrab below shows the results.
No transatlantic signals were heard, but a couple of signals from Siberia, east of Novosibirsk, in the hour or so after midnight, were nice to see.
I'll repeat the exercise soon using the dipole.
