HaliKey, from Halibut Electronics, is a small USB device that connects morse code paddles, or a physical PTT switch, to a computer.

This allows you to use physical controls when operating your radio remotely. HaliKey is available in two variants: HaliKey Serial, and HaliKey MIDI. See the table below to decide which one to get.
