   Other applications include antenna testing, frequency stability and frequency accuracy checking. Usually a WSPR station contains a computer and a transceiver, but it is also possible to build very simple beacon transmitters with little effort. For example a simple WSPR beacon can be built using the Si 570, [5] or Si 5351. [6]

   The FCC asserts Amcrest marketed "UV-5R-series FM hand-held radios capable of transmitting on 'restricted frequencies'". [10] Later revisions of the UV-5R sold in the US had transmission frequencies locked to the ham bands, however, there exists a key combination to unlock the ability to transmit on the full band.

9. Amateur radio propagation beacon - Wikipedia

   en.wikipedia.org/wiki/Amateur_radio_propagation...

   A large-scale beacon project is underway using the WSPR transmission scheme included with the WSJT software suite. The loosely coordinated beacon transmitters and receivers, collectively known as the WSPRnet, report the real-time propagation characteristics of a number of frequency bands and geographical locations via the Internet.
