The Eton E1XM is a full-featured AM/FM/SW/XM radio replacement for the Grundig Satellit 800. Designed to resemble the Satellit 650, the E1XM is described as a “bold and fresh new contender in the World Band portable radio market.” In fact, the Eton E1XM is the first portable radio to combine AM, FM, SW, and XM into one module. In addition, whereas the Grundig models were large and heavy, the E1XM is lap-size portable and measures approximately 13”x7.5”x3”. Although there are smaller radios out on the market, none of them come with XM included.
