4W     - The Lagunaria DX Group's DXpedition  to  Timor Leste  (11 October-8 November) [425DXN 1505] has been postponed  until sometime in 2021. "The current  situation  based  on  the  Corona pandemic  makes  it impossible to plan  anything  later  in this year",  the team says. "The uncertainty of  travel safety,  the not predictable impact  on the companies we have to rely on and the current restrictions  that prevent a solid preparation, forced us  to take this step.  We hope that we  can see clearer  by the end of  this year  what will be in 2021". Updates will be posted to http://timor-leste-dx.de/.
