I’ve got a Cricket 80a with marking, © 2017 that I bought a couple years. It’s all built up. Transmitter works. Receiver works for about a second after power or key up and then fades. It is probably something simple but for the life of me I can’t find it.
Everything is there except the key arm which I stole to use in another setting. The one with the key jack on it is mounted.
If someone is interested in it make me a modest offer and I’ll likely accept.
