As was reported here, CCrane has fixed the medium wave AGC issue on the CC Pocket Radio (item # CCPKT selling for $59.95 on their site).
I wrote to them asking about how can one tell the difference between the old, and updated models. This is their reply:
The easiest way to determine if the CC Pocket Radio (item # CCPKT for $59.95):http://www.ccrane.com/radios/pocket-radios/cc-pocket-radio.aspx has the upgraded MW AGC is to look at the round push button presets on the front of the radio. If they are blank then they are from our first shipment. If the round push button presets are numbered the radio has all the updates.
