This is an old electronic scheme of the Handy Talky (HT) circuit. This electronic circuit is quite popular among electronic hobbies in the 90s. If you have already built this scheme, maybe you are old enough now 🙂
This handy talky scheme is an original scan of the kit on the market, so this scheme is guaranteed to function properly. Because this kit circulates in Indonesia, some information in this scheme uses Indonesian. Please use Google Translate to translate it 🙂
