Anyway [gad this is abysmally distant from SWLing and QRM - Dirk, you
can't possibly still be with us can you?],

Sure Richard, I'm still listening in on this thread; I'm now thinking
about a 518KHz Gaussian antenna... :0)

BTW, it has been raining over here for 2 days, and the QRM levels are
still fine!

I have also done the following experiment: Instead of the commercial
"magnetic balun" I was using, I have now rolled my own 1:9 unun. The
main difference with the MLB is that the unun has isolated windings.
The primary is grounded to the earth rods, the secondary is grounded
via the receiver. I thought this was a better solution with regard to
ground loops.
