 OpenWebRX should work out of the box on your RPi, if you set it up by [going through this guide](http://ha5kfu.sch.bme.hu/openwebrx-quick-setup).
 
-You will need a **Raspberry Pi 2**.
+You will need at least a **Raspberry Pi 2**.

+> As noted by Zsolt, HG2ECZ the Raspberry Pi 3 can limit the CPU frequency if the power supply cannot supply enough current. It may result in decreased signal processing speed! Having a correct power supply is insufficient for running OpenWebRX. An **5V, 2A** unit (or better) should do.
 
 **Raspberry Pi 1 won't work** as its CPU just doesn't have enough processing capability to make it.
