Thanks, Joe. This is exactly the kind of input that we need here. :-)
1843? I believe you. In this area (SW MO) and at the times I tune around, I
haven't heard much below 1850. I can think of regular groups on 1850 and
1880. But I'm not going to go there, except to suggest that whatever groups
there are invited to be involved.
