[Ham-Mac] RFI in mouse

[Bob Nielsen]

Those are both 2.5 GHz mice, so RFI (at HF/VHF anyway) shouldn't be a  
problem, assuming there is adequate internal filtering.  They do not  
appear to use Bluetooth, but possibly use a similar digital coding  
sequence with different codes to identify the specific mouse.
