-ODR-DabMod has been tested working with HackRF from Great Scott Gadgets on i386

-The unit is an entry level yet versatile SDR which provides coverage between

-generated with it in VHF Band III (174-240 MHz) L-Band (1462 - 1467.5 MHz) and 
-even the worldwide ISM Band (2400 - 2500 MHz). The latter (subject to your local
-regulations) is a licence exempt band which may be useful for performing freely

+band which may be useful for performing freely radiating tests at low power. Cheap 
+MMDS converters are currently available which helpfully provide a Band III IF output
+providing a direct feed to the aerial input of a receiver. Before choosing a converter
+it is important to pay close attention to the specifications. The local oscillator 
+phase noise performance, and the dynamic range (due to the heavy use of the band) are
+both particularly important.   
 
 To use HackRF, the output of ODR-DabMod must be set (in the configuration file) to
 produce 8-bit signed integers, rather than the default complex floats.
