The future of shortwave?
 

Don,

As for the cost of fixed stations.. I think WBCQ is on the cutting
edge, building a wind farm to power it's transmitters..

HCJB in Quito Ecuador built dams and hydroelectric generation facilities
to power there mega watt transmitter site.

I thought it was 500Kw and more recently it has been running 100Kw to
allow other transmitters in the region to also be used!
