A list of beacons on frequencies of 144MHz and up appears in most editions of the VK Callbook.
We used to maintain on this page a more up-to-date listing of the status of VK and ZL beacons on the 144MHz to 2.4GHz bands. However Adam VK4CP hosts a beacon page on the VK Logger at http://www.vklogger.com/ and we recommend that listing as more current than we are able to provide here.
