Hello All,

First, thanks to everyone who let me know that my test message worked - my 
first experience with a mail reflector.

Does anyone have a noise blanker for the 580 Delta lying around? I think it 
is a model 289.

Or, does anyone have any documentation? Can the n.b. be "home-brewed"? The 
580 manual has sparse info except "the optional noise blanker goes here."

Thanks to all!
