+Your HackRF (the board under the PortaPack) has the ability to send or receive radio waves in a broad frequency range. Some of its specs are:
+
+*	Transceiver: Half-duplex
+*	Operating frequency: 1 MHz to 6 GHz
+*	Supported sample rates: 2 to 20 Msps (quadrature)
+*	Resolution: 8 bits
+*	Max TX power:
+    *	10 to 2150 MHz: 5 to 15 dBm, increasing as frequency decreases
+    *	2150 to 2750 MHz: 13 to 15 dBm
+    *	2750 to 4000 MHz: 0 to 5 dBm, increasing as frequency decreases
+    *	4000 to 6000 MHz: -10 to 0 dBm, increasing as frequency decreases
+*	Max RX power: -5 dBm. Exceeding -5 dBm can result in permanent damage! Can safely accept up to 10 dBm with the front-end RX amplifier disabled
+*	CLKOUT/CLKIN: 10 MHz square wave (0V to 3V for a high impedance load)
+
+From that list that might be confusing for the first user, we could extract few interesting points:
+
+* Half-duplex: Means that it can send OR receive, but not send AND receive in a particular instant.
+* Operating frequency: goes from 1 MHz to 6 GHz, that means that the device is able to send and receive signals from almost all the common sources you can imagine. You can see the range with more details [here](https://en.wikipedia.org/wiki/Frequency_allocation).
