Jag fick ett rekord rapporterat:

50 MHz ES OZ1DJJ JO65HP - PY5CC GG54.

Detta gav mothugg, se nedan. Skall det vara något annat än ES ?

Dear Tommy,

I have seen your new update in which you have added two 50-MHz new sporadic-E records between stations in north Europe and south America. However I have some doubts that those QSOs actually took place in the sporadic-E mode.

To my understaning of sporadic-E propagation, QSOs between the northern emisphere and the southern emisphere cannot take place via sporadic-E because, if the station in the northerm emisphere is in summer, the other one would be in winter. And multi-hop sporadic-E requires both stations being in sporadic-E conditions.

Even in winter we rarely have some short sporadic-E conditions, but these are very localized and unsuitable for multi-hop QSOs.

I have put a question just on this very issue on the UKSMG reflector, to know the other's opinion.

Best regards. Tony, I0JX

Hej Tommy

Mina liknade kontakter klassar jag som F2.
Men vad det var är nog svårt att veta med säkerhet.

Visst kan man köra Multihopp E på vintern. Men det är mest likely att det var när dansken hade sommar o Brassen hade vinter. Kan vara mix av ES och F1, kan även vara F hopp som sagts eller TEP (Trans Equatorial Pvad P nu står för.
