I use Desheng pl-380 radio and listen to cri broadcast from Beijing in Suzhou at night. The frequency is sw7325KHz, and the battery can listen normally and clearly.
You try to turn on the radio and get close to the charger, and then you find that the signal-to-noise ratio of the radio is greatly reduced, and the original program is even completely disturbed. I don't know what the reason is, but it may be high frequency interference. What I don't know is that the USB cable is actually plugged into the USB port of the radio, and the cable has become a part of the antenna, which is powered by USB, which is equivalent to putting the antenna close to the charger, thus causing the above interference.
