I had that in my favorites for a long time and I must have deleted it when things went wonky.  

This forum is still going, but very few postings, occasionally something gets posted that stirs it up for a while, then goes back silent:  amradio@mailman.qth.net  There are a lot of knowledgeable old timers hiding out on there still.

I think there is a website associated with this but can't find it now.
