The Baofeng DM-5R and RD-5R have a FM broadcast receiver chip in them.
|
|
|
|
However the markings on the chip are not of the RDA5802, and the chip does not appear to be a RDA5802
|
|
Hence this datasheet has only been added as a general reference to broadcast FM receiver chips.
|
|
|
|
The chip in that is in the radio is connected to the same I2C bus as the AT1846 and the EEPROM, and is on the same address as
|
|
the RDA5802, but the chip does not resond with the correct ID code.
|
|
|
|
I think it returns ID code 0x02 when it should return 0x58
|
|
|
|
Also reading some other registers in the chip, do not return the default values that a RDA5802 would return.
