RDA1845 channel steps?
I have a question regarding the RDA1845 and possibly the 1846: According to the RDA1846 "datasheet" that is floating around, the chip only supports 12.5 and 25kHz steps. The DRA818s, in which the 1845 (or was it the 6?) is used support the same. The Arduino library for the DRA818s also only mentions 12.5 and 25kHz.
The 1845 can probably be called the initiator of a number of cheap Chinese handhelds, like the UV-3R I have. That transceiver however supports also 20 and 10kHz.
So my question: Is the datasheet incorrect? Does the 1845/6 support 10/20kHz steps? And if, does anyone perhaps know how? (command)
