The only difference I see is that instead of one 18650 battery there are now 2 of these and they are practically useless in anything that doesn't have the necessary positive contact, The recessed positive terminal on any 18650 battery provided by the 18650 design (here) prevents the device from being mounted backwards, but some might suspect that this will not work if mounted backwards becomes. Channel frequencies instead of (2) SW bands, strangely the front label still says SW in the band list, but at least the brand has changed the frequency label on the back from AM/FM/SW to AM/FM/NOAA. Inside the box is a list for each range set, none of which are marked indicating which range set is being used, except for the label on the back of the unit. It takes some time to get used to the buttons to avoid the on-screen error message. because the instructions are these repeated sentences that end up talking about the 9kHz stepped tuning available on the SW model, but they all use the same model number "HRD-900".
