Ten Tec sells kits too:

Bear in mind if you are getting a shortwave radio to hear the time clock on WWV, virtually any cheap shortwave receiver will do the job, so you don't need to save money by building from a kit. Keep in mind also that due to propagation variences 10 mHz may be favorable, but also try 5, 15, and 20 mHz (higher frequencies in the daytime, lower at night), which are alternative frequencies for WWV.

Since you asked in the astronomy section I presume that getting the exact time is what you're going for. You might consider buying an "atomic clock" which is synchronized to WWV.

Answer 2

Buy a kit and follow instructions for soldering. Or you have to find a schematic drawings available in the internet at electronics hobby sites. But then you would have to know electronic components and also do the pcb yourself!

Answer 3

I think you asked how to build one, not what it is..... ;-) ....!
The cheapest and easiest way to build one is a so-called "PC-radio" which you hook up to your (yes!) PC (serial for juice, and sound card Audio In to amplify), but the only reference with build instruction I know of is in German....
Have a look at it anyway, may be you get the concept.
