Or just buy a shortwave radio! They are still made, and a high quality shortwave antenna for receiving purposes is simply a length of wire, as long as possible, and as high as possible.
The shortwave band (also known as “HF” radio) is a fascinating introduction to the subject, and while it is no longer full of long-range commercial radio stations, the propagation characteristics of the band mean it is still useful for things like WWV and amateur radio communication.
If you live on the west coast, you can enjoy the pleasure of receiving both WWV (broadcast from Colorado) and WWVH (broadcast from Hawaii) at the same time, on the same frequency. Their voice announcements are intentionally offset so that they never overlap.
If you have one of the popular RTL-SDR's you may be able to pick up the HF bands by enabling the direct sampling mode (allows tuning between 500kHz - 28.8MHz).
