This lack of documentation is a widely acknowledged problem. As one radio enthusiast forum notes, "Eton radios are notoriously difficult to find service info for". For this reason, some owners suggest searching for Tecsun S-2000 service information, as it may be more accessible, though differences between the versions do exist.

A specific and widely reported performance issue is that the Satellit 750's frequency readout can be off by about 1 kHz on the shortwave bands, which is a known calibration inconsistency. This error can also vary depending on whether the radio is set to "Wide" or "Narrow" filter mode. It's a common characteristic of these radios, as the ceramic filters used in the IF (Intermediate Frequency) stage are known to have highly variable symmetry. If this 1 kHz offset is a major problem, resolving it may require replacing the stock filters with precisely matched pairs and performing a complete alignment of the receiver.
