Bob Sutton - ZL1RS

6 meters / 50MHz

 

Some interesting 6m DX during the Solar Cycle 23/24 minimum years.

 

 

South America to VK and ZL

 

Han JE1BMJ provides an overview from a northern hemisphere persective:

Graham KE4WBO suggested the propagation mode is "mesophere echoes along auroral electrojet":

Screen shot of OA4TT calling VK4ABW on JT65a

Note the clear JT65A Sync Tone (in between my 100Hz SMPSU "buzz"). This shows there was no "frequency dispersion" on the signal indicating that there were very few reflection points on the signal transmission path.

Japan to ZL - North/South Solstice Propagation (Es linked TEP?)

 

Periodically we get propagation from Japan during the "normal" TEP seasons of November
and March/April, but this summer we saw several openings in December and January:
