I’ve put up an early release of some maidenhead locator web tools I’ve been playing with. Full details can be found on the locator tools page or you can just jump straight in and have a look over at http://loc.vk7is.net/.
It’s currently just using various free hosting services, but if I find there is any use of it I may change that. So don’t expect anything too superfast (or reliable). 🙂
