I haven't come across David, W6DTW's blog before, but it's well worth a read.
His latest post on Shooting ourselves in the foot: Amateur Radio's Culture of Exclusion is well worth a read. David describes the problem admirably, though doesn't really suggest how we might find a solution (which I think most of us would struggle to do!)
David's point about Twitter in the last paragraph is well made and I know will cause some friends in two CW clubs I could mention, a wry smile!
Check out too, David's posting on 'An example of why Amateur Radio is failing to attract young people'. Interesting points.
Practically, there's an interesting link from K6DBG on how to turn a WiFi router into an APRS digi.
Thanks for some thought provoking posts, David! I've added you to my RSS reader!
