KC8JCRigctl 0.1.1 Install (needs Python 3.11+ and pipx): pipx install https://www.kc8jc.com/kc8jcrigctl/kc8jcrigctl-0.1.1-py3-none-any.whl Upgrade: pipx upgrade kc8jcrigctl Remove: pipx uninstall kc8jcrigctl You also need Hamlib, which provides rigctl and rigctld. That comes from your OS packages - brew install hamlib, apt install libhamlib-utils, or hamlib.org. It is not a pip install. On Linux your user must be in the dialout group to open /dev/ttyUSB*: sudo usermod -aG dialout $USER Then log out and back in - a group change does not apply to the session you ran it from.
