ARLA/CLUSTER: SSSP - Short-path Summer Solstice Propagation em 50 MHz

[João Costa > CT1FBF]

SSSP on 50 MHz around our Summer Solstice

This week's SARL News reports: The Short-path Summer Solstice
Propagation (SSSP) was discovered by Han Higaso, JE1BMJ, when he
contacted European stations on 50 MHz from Japan in the month of June
around the summer solstice in the northern hemisphere.

The VK and ZL amateurs have also exploited this new mode of
propagation when they worked South American stations during their
southern hemisphere summer solstice in December.

Last Year Bob ZL1LS ran skeds with South African VHF amateurs, and
traces of his signal were heard by Paul ZS6NK.

The best time to listen for SSSP signals from the East is from our
sunrise (in SA) until their sunset.
