Default Eton E1 Recall

There are similarities, although not to the degree as between the SW8
and the Satellit 800. In Van Horn's E1 review in Monitoring Times, it
is written that "Drake did have a major hand in the electronics of this
unit."

The E1 seems to be an SW8 in a *Grundig* Sat900 case plus XM added.
