Later I was listening on 2 metres and was surprised to come across a signal on the odd frequency of 145.3375 (it's always surprising to hear a signal here on 2 metres, even one of the three locally accessible repeaters.) I was even more dumbfounded to discover that I was listening to a contact between UA3ECF and someone in Ireland, and the UA3 was a 59 signal!
When the contact finished I tried calling the UA3 but no-one came back to me. After a while Keith, G0EMM came on and told me that I was hearing his EchoLink node G0EMM-L in Workington. He explained that I needed a 77Hz CTCSS tone to access the node, which is why no-one had replied to me. I would also need a DTMF key pad if I wanted to connect to specific stations or conferences on EchoLink. I was glad of the explanation as I was starting to doubt my sanity and wondering if I'd witnessed some amazing propagation or whether my K3 receiver was somehow re-radiating 40m on the 2m band!
I'm not anti-EchoLink although I dislike the CQ100 VOIP system. EchoLink is at least intended to link together stations using real radio, bringing life to dead repeaters. And it does it in a way that is compatible with most existing equipment, unlike D-Star, so it should be encouraged in order to prevent the subversion of aspects of our hobby by commercial interests trying to promote sales of a certain manufacturer's equipment.
This part of the world could do with something to stir up a bit of VHF activity. When you can hike up a small mountain with a clear take-off for hundreds of miles, make fruitless calls through half a dozen different repeaters and log just two contacts, it's hard to argue that an EchoLink node is unwelcome. In fact it could provide a way for me to chat with some readers of this blog for whom a direct radio contact would be impractical. But having the ability to use the HF bands and have chats like the one I had earlier with G6YWL I probably won't be making much use of it.

I used to have exactly this feeling re. the manufacturer until I discovered that the D-STAR protocol was created through research funded by the Japanese government. It's an open protocol - anybody can implement it - ICOM was just the first.
[Current D-STAR implementations do use a proprietary voice codec, though there's nothing to stop anybody substituting their own.]
