As you already have Pi Zero, use Pi zero's 5v adapter with Pi B for trial.
Tried and my verdict is my sdr dongle is the fault even found an app for Android and tested it on there it gets scorching very quick 1-2 mins then stops sending data, dismantled it and back of pcb is discoloured under both of the main chips.

This was a cheap and cheerful one from China and has lasted about 18 months any recommendations on another or do they all eventually burnout as I know they all run warm
