Cloudlog is a self-hosted PHP application, which allows you to log your amateur radio contacts anywhere all you need is a web browser and and internet connection.
Its possible to interact with your radio if you have a K3, FT-950 or a ICOM radio using a nice application that Rob (M0VFC) has put together called [CloudlogCAT](https://github.com/rmc47/CloudlogCAT). The application is still in active development and lots of new features are due.
