DSR what? try getting a model number.

 

[Jim "Spot" Beam]

Model is possibly DSR-4400

Right clicked on image to save and the DSR4400 was in the file name.

Looks like it is a DCII decoder perhaps. Links from google showed them in use by educational systems.

A little leary of just buying a DCII without knowing I can do something with it.

Anyone have one of these or know if they can be used?

The seller has 98 and has sold none since 9/06.
