Stefan,

a philosophical approach to define DX : distances that are a
challenge.
What would mean that what is considered DX can differ from band to band
and on the same band even  from one station to another: running 1W
ERP on 137kHz DX could be 5000km or more , running 1mW ERP it could be
500km or more.
I have always had a bit of a problem with the "outside the own
continent" definition. For a ZB2 station it would mean that CN (can
be as close as 10km) would be DX while UA (at up to 4000km) would not be
DX.

PS: as it returned from a family visit last Sunday I saw your
announcement and just hooked up the 500kHz antenna (11m high and 25m long
lazy L) to the sound card. I could see something going on at 8970, but
too weak (and too much QRM/QRN) to decode. It time permits I will try to
bring the antenna to resonance at 9kHz for you next test.
