WWV time signal stations on the chopping block

This project just used a short wire:

and this project re-purposed a loopstick:

At low powers and short ranges, antenna matching isn't any big deal.

So, it's been done before.  If WWVB goes SK, I'm sure there'll be a small cottage industry selling "clock setters" on eBay.

Carl:
WWVB could be synced and transmitted over power-line on a small budget.

Looks like there has already been a market for such devices driven by people in countries without signal reception (like Australia).  For example: https://unusualelectronics.co.uk/products/chronvertor/.  For some it can be done using just a PC and some wire.  http://www.jrcomputing.com.au/Set_Watch/Set_Watch_Auto.html  Very clever thinking here.

Mr. Bill:
 :facepalm: :pissed: :banghead:

That's just brilliant.  Every household "atomic clock" becomes worthless.

I have a feeling this'll get reversed when the manufacturers raise a stink.  But we'll see.

That’s pretty damn clever! 

Hands down the simplest way to at least keep my Japanese solar watches functioning as intended, post-WWVB. Clocks costing 10’s of dollars are less painful to replace than watches costing 100’s.
