With a budget of 1000 RMB, I can buy an RTL-SDR and a DE-990 together. I'll connect the SDR to an antenna and then use it with a radio to listen. After buying both, there will still be some money left over.
I recommend using a laptop or Android tablet, and finding it outdoors.
The SR286 does not have a single-band receiver; therefore, if you want to listen to amateur radio channels, do not use it.
