Diy shortwave radio.
Test the audio transmission and reception by speaking into one walkie talkie and listening for the audio on the other. Take the walkie talkies to different locations and assess the range of communication. Experimenting with different antennas can also enhance the range of the walkie talkies. 4. Ham Radio Receiver.
