Can Desheng R9702 radio use an AC adapter?

Hudson R9702 radio can use AC adapter. The voltage may be about 4V. If the power output current is large, it will have little effect on your radio. On the contrary, if the output current is too small, the radio will not work normally.

The design of AC adapter filter circuit has great influence on radio. If the filter circuit is well designed, the receiving noise of the radio will be smaller; If the filter circuit is not well designed, the receiving noise of the radio will increase obviously.

If your radio is Desheng R9702, you can consider choosing the power adapter of Desheng DC-05A.

And to explain, I also used this power adapter with Desheng R9702 radio.

Of course, if you can find a power adapter with a power supply of about 4V and an output current of more than 250mA and a better filter circuit to match your radio, the reception effect will be better.
