    Already,ham operations  on 630m  are  extending remarkably: Hawaii, Australia, Japan, CaymanIslands, Canary Islands, Reunion Island.  I’m  imagining  areas  of  possible  new 630mactivity  in next 10 years from a  ham/experimenter availability/accessibilityviewpoint  and moderate-to-lower Tstorm standpoint. What do  you think?  http://en.wikipedia.org/wiki/Atmospheric_electricity#/media/File:Global_lightning_strikes.png 
    In-country laws  and administrationsmay not permit 630m  in some of  these places, at least for  a while yet.  Please post corrections  and additions  or sendthem to  me  at mrsocion at aol.com .

AREASOF POSSIBLE NEW 630M ACTIVITY IN NEXT 10 YEARS
    As  new possible 630m areas, consider Chile(Concepcion, Santiago), Argentina (Bahia Blanca), Brazil (Sao Paolo, Rio deJaneiro, Belo Horizonte), Turkey (Ankara), Israel, Egypt, South Africa (Capetown),Dubai, S. India (Hyderabad, Bangalore), SW Australia (Perth), and central Siberia(Novosibirsk, Krasnoyarsk, Ust-Ilimsk, etc).  South Korea  and northern/central China (Beijing,Yulin, Yanan, Xian, etc.)  offer additional possibilities. Locations may be  favorable for 630m  in low-Tstorm  areas where  universities,electrical/electronic industries, and/or scientific outposts  exist.  Advances  in  conveniently-erectable 630mantennas that  are  also radial-free  can facilitate  such stations.
   BestVK/ZL –CE/LU 630m propagation would be  expected  in S. Hemisphere mid-fall andwinter (N. Hemisphere spring-summer).  N/Shemisphere 630m communication between mid-latitude stations between hemisphereswill probably cluster within  a month  or  so  of  one  or  both equinoxes  at times whenrainy seasons do  not  interfere
   Various islands too  numerous to list may  also be activated  in the Caribbean  and  in the Mediterraneanareas.  I mention just a few more areasor islands globally  as well: New Zealand, Oceania, Azores, S. Greenland.  
    Among the  less probable 630m locations, dryseasons may  also permit temporary operations  in very stormy areas  in E. Asia,India, Taiwan, the Philippines, central  and northern South America, the Falklands (Malvinas), andsub-Saharan Africa.  High noise storm levels  and adverse wind/moisture conditions can be  expected during wet seasons ofcourse.  E/W propagation  in  and betweenequatorial zones by 630m hams  and experimenters  is yet to be probed.  As far as I know, equatorial anomalypropagation  on 630m  involving temperate latitude locations has yet to  be  demonstrated  or even found to exist.
    Antarctica, N. Canada and Murmansk  area  inRussia  are also 630m-possible areas. However, auroral absorption, punishing weather, and frozen ground pose challenges to 630m station-building in these places.  Possibly temporary antennas might be  set up  and later secured down or  away, before  the predictably worse weather seasonsbegin.  
   Some of the  ideas here may seem far-fetched,and they are offered in the  ham spirit of possibility and  opportunity.  The future will probably make fools of  us  all!  Thank you  for reading this post.
