Guten abend, Thomas.
John Devoldere in his books states that 160 meter band is a different band
than all others. 80 meters can be predicted/modeled fairly accurately. But
160 is still full of wonder and new learnings.
11 years on top band, I have not observed any difference in propagation
between 1820 kHz and 1980 kHz. That is a great question. Maybe it is only
by tradition/history that the DX is mostly close to 1.8 MHz? This could be
a fun experiment for data collection...using WSPR or QRSS.
