AMSat has appeared several times (it's suggested that different functionalities be combined in a single introduction). pistar.uk also appears twice.
Reverse Beacon Network is missing the final 'k'.
The International Beacon Project Transmission Schedule can be found on the page below NCDXF, and I recommend adding the "/beacon" suffix to the URL.
The rest are good, but I remember seeing a yellow page navigation with a ham theme before… We could consider contributing to similar projects to avoid reinventing the wheel.
Thank you for your contribution.
