 ## Transmit Power
 
 HackRF One's absolute maximum TX power varies by operating frequency:
-* 10 MHz to 2150 MHz: 5 dBm to 15 dBm, generally increasing as frequency decreases
+* 1 MHz to 10 MHz: 5 dBm to 15 dBm, generally increasing as frequency increases (see this [blog post](https://greatscottgadgets.com/2015/05-15-hackrf-one-at-1-mhz/))
+* 10 MHz to 2150 MHz: 5 dBm to 15 dBm, generally decreasing as frequency increases
 * 2150 MHz to 2750 MHz: 13 dBm to 15 dBm
-* 2750 MHz to 4000 MHz: 0 dBm to 5 dBm, increasing as frequency decreases
-* 4000 MHz to 6000 MHz: -10 dBm to 0 dBm, generally increasing as frequency decreases
+* 2750 MHz to 4000 MHz: 0 dBm to 5 dBm, decreasing as frequency increases
+* 4000 MHz to 6000 MHz: -10 dBm to 0 dBm, generally decreasing as frequency increases
 
 Through most of the frequency range up to 4 GHz, the maximum TX power is between 0 and 10 dBm.  The frequency range with best performance is 2150 MHz to 2750 MHz.
