BTW - I work in radio news - I did a story in the fall about the federal government investing A LOT of money in a new TUBE BASED, HI POWER analog transceiver.
Speculation was that it's being built as a backup in case a nuke blast or solar event knocked out the digital systems. I don't have a link to the source now but it was an interesting read for radio folks.

I’d be very interested to read that if you can find the source.
