A while ago the possibility of running a SOTA net was discussed here. Unfortunately it never came to anything as it was not possible to choose a frequency or mode that everyone could join in with. At the time I suggested using Skype. However a much better option (and one that can involve radio) might well be Echolink.
I have been experimenting with a personal Echolink node which covers a wide area. I use it to chat to some friends in the US and it has proved very successful. Over favourable paths it covers 20 miles or more. However, if you don’t want to set up your own node, there are many open RF nodes available that can easily be connected together to form an international net. The linking can even be done automatically at a preset time using software called “Echolink Producer”.
Even if you can’t access a node or internet linked repeater, Echolink can be accessed directly from a PC or even a smartphone/iPhone (free app). I realise that some people object to Echolink on philosophical grounds and will not wish to participate, but that does not stop the rest of us taking advantage.
To allow maximum participation an early evening net (Eu time) on a Saturday, might work well for Eu and NA?
Echolink is free and effective. To participate you need to prove that you have a valid amateur radio licence.
