Description:
HaliKey is an adapter that allows you to operate morse code with your favorite paddles, or to have a physical PTT switch, while operating at a remote station:

HaliKey is available in two variants:
- HaliKey MIDI is designed to work with radio control software that uses MIDI events to trigger radio button presses, such as NetKeyer, the various Ham Radio Apps for MacOS and iOS by Marcus DL8MRE and Jan Roskosch, Remote Ham Radio, and others.
- HaliKey Serial is designed to work with radio control software that uses serial port flow control signals (CTS/RTS and DTS/DSR) to trigger radio button presses, such as SmartSDR for Windows.
Here’s a table of the applications I know about, and which ones support which HaliKeys:
