I have the ID52A because of it's Bluetooth and Color Screen, I tuned off the Back light of the Screen, its a Transflex Screen that can seen in Bright Day light,
Requesting retransmission of missing blocks would be hard to implement as sending a pictures is often one to many. But if the sending station sends the picture multiple times the radio will fill in the missing blocks and only store the image one.
I still don't understand why Icom puts so many different portable radio's on the market in a short period of time. For the ID-52 you need a 3300mAh battery (aliexpress, 36 euro), otherwise you will have to use a full battery twice a day (1880 mAh battery is not enough for 10 hours). I live in the Netherlands and have the id-52A & id-52A. The radios are nice, I have 4 spare batteries 1880mAh.
Neither radio comes preprogrammed. If you don't want to do any programming, I would recommend finding someone who has the same radio and cloning theirs.
