Another good article on the subject from IEEE 2 years ago with good sidebar 
articles and video:
"Of all the parts of the power grid, high-voltage transformers are among the 
most likely to fail in a geomagnetic storm and also among the most difficult to 
replace. If a big storm were to knock out several hundred transformers in one 
fell swoop, manufacturers wouldn't be able to supply replacements quickly-there 
is no global stockpile. EHV transformers, which can handle voltages of 345 kV 
or higher, weigh about 200 tons and cost about $10 million each. Building one 
requires exquisite, near-artisanal craftsmanship, including meticulously hand 
winding the paper-tape insulation around the copper winding at the 
transformer's core. One EHV transformer can take several weeks to assemble and 
test, and it takes years to train skilled assemblers. Even the largest 
transformer plants can build only about 30 to 50 per year. With the shortage of 
skilled labor and specialized materials that would likely accompany a prolonged 
blackout, simply maintaining that level of output would be a cha
 llenge, never mind ramping up new production."

The radio outage will be the least of our problems after a big one.

Whether it's major or minor, there is a massive CME on the way.  The 
article is written for the general public, but worth reading:
