Fisher-Price 815 Vintage Sky Talker Walkie Talkie Set Morse Code

Vintage walkie talkie toy set from the 1980s. I tested the set and while both power on and give the correct static sound, I cannot get them to connect to talk through. Consider these as not working correctly, so they are priced accordingly. Can be used as a display piece or for somebody to repair. My guess is one has a loose antennae wire somewhere on the inside.
