Ok, Steve, we got receive back.  Readjusted everything according to 
instructions.  Also under the sl/usb codec speaker settings, changed 
freq response to 11025.  ARan test again, and it's reading the files.

Does it help if I size the creen by character width and line height 
under mtty?  Also, anywhere I can get sounds of PSK31 so as to know 
what to listen for?

Also, which knobs on the signallink do what?  Far right is 
vox?  Other two knobs set pointing straight up.

Oh, no smoke yet - but wait ... there's more!--Matt, N1IBB.
