Extreme tropo in Australia

Post by zach_m » 08 Dec 2018 12:09

DXers in Australia experienced an extreme tropo ducting over Tasman Sea. New Zealand signals were heard in Australia with distances exceeding 2000 km.

These two videos are no longer available (maybe there was too much music inside?), but the same user added some new videos: https://www.youtube.com/user/dxer22000/ ... _polymer=1

I have just ordered a XHDATA D-808 used in the YT Video for inflight FM entertainment also possible portable FM DX for 2019 Sporadic 'E's season & Vacations. Also possible AM use?

The below link help decide for purchasing the XHDATA under 70 euros

The D-808 is an excellent performer on MW with the built-in ferrite antenna and also on SW with the rather short whip antenna.

Forget about it on LW though unless you have a decent external (loop) antenna for LW.

Anyway, overall the D-808 is a very pleasant radio for mobile DXing at its price tag and so far it's the first portable in the sub €100 price class that brought me overseas catches on MW with just the internal ferrite antenna.

Hello Franco,

At the time when I was posting this link the videos were still available, but the folowing day he (dzer22000) decided to removed it (due to better reception) as he explains in the box below one of his uploads. I don't think such an extreme tropo is possible over the land (in Europe). Tasman sea and tropical climate strenghten the signals/distances immensly. This is actually first proove of such an extreme tropo that has been recorded.

Who told you this?

Hi Peter,

Perhaps I missed something, but I actually never seen a prove of Australian tropo with distances over 2000 km. If you have any links to such an extreme tropo catches/recordings please post here. I would love to see it.
