In this year, at the times selected to communicate with Cruising yachts in the waters of South East Asia on the 20 metre band on frequencies 14000 >> 14350 MHz . propagation has been very poor.

To understand the reason for this, an excellent free programme is available by contacting :-

Christian RAMADE (F6G QK) http://dxfile.free.fr

The Programme is PropHF ver. 1.3a

It demonstrates clearly that if you try the 20 metre band 0000Z and 0230Z you might get long path contacts but that's all.
