+# The Yardstick One and RFcat Notes
+
+As we covered in the Wireless Hacking video course, the Yardstick One is a very useful piece of hardware to perform testing of RF devices that communicate in frequencies under 1GHz. It can be combined with many tools, including RFcat. The following are a few links and resources that we discussed in the video course related to these tools:
+
+## Yardstick One
+* Yardstick One website: https://greatscottgadgets.com/2015/09-30-introducing-yard-stick-one/
+
+## RFcat
+* RFcat website: https://bitbucket.org/atlas0fd00m/rfcat
+
+The following are several useful RFcat commands:
+
+* d._debug = 1 – dumps debug messages to the screen
+* d.debug() - prints state information every second
+* d.discover() - listens for specific SYNCWORDS
+* d.lowball() - disables most “filters” to see more packets
+* d.lowballRestore() - restores the configuration before calling lowball()
+* d.RFlisten() - listens for signals and dumps data to the screen
+* d.RFcapture() - dumps data to screen, returns list of packets
+* d.scan() - scan a configurable frequency range for “stuff”
+* d.setChannel() - sets the channel to be used
+* d.setFHSSstate() - sets the FHSS state to be used
+* d.setFreq() - sets the frequency to be used
+* d.specan() - a spectrum analyzer
+* print d.reprRadioConfig() - print pretty config infoz
