The Sangean RCR-3 specs says it has a 3-inch speaker, the same size as the speaker on the Sangean WR-2. Considering the RCR-3's smaller footprint and lower cost, that would make it appealing. However, I notice its atomic function gets some customer reviews reporting more glitches than are observed with the WR-2.
With my 6 year plus old WR-2, I have to DeOxit the headphone jack about once every two weeks or so because the sensor doesn't tell the speaker to turn on when my earbuds have been removed from the jack. So I've been keeping my eye on a bedside radio replacement if the problem deteriorates.
