-  * It is mandatory to initialize ALL radio modules within the PicoSDR. The PicoSDR 2x2 contains RF Transceiver, it means we will have 2 ''Radio420 TX'' blocks and 2 ''Radio420 RX'' blocks
+  * The Radio420x is a Multimode SDR [[https://en.wikipedia.org/wiki/FPGA_Mezzanine_Card|FMC]] RF transceiver. PicoSDR 2x2 contains 2 Radio420M modules which are MIMO capable //(M for MIMO, pretty smart, huh ?)//. Here is a [[https://www.nutaq.com/sites/default/files/Radio420x_V1.3_03_24_2014_web.pdf|product sheet]] for more info.
+  * It is mandatory to initialize BOTH radio cards, even if only 1 is used. So, since our device contains 2 Radio420M transceivers, it means we will have 2 ''Radio420 TX'' blocks and 2 ''Radio420 RX'' blocks
+  * Now, we only need one transmitter per node, so make sure to enable only the Radio420 TX of Card 1, and set the gain values as following :

+  * For the 3 remaining ''Radio420'' blocks, we only need to disable them by setting the __Enable__ parameter to __False__

-There isn't that much done in here since all baseband processing is done by the FPGA. All that is left is to connect a ''**File Source**'' block to the ''**RTDEx Sink**'' block, and specify the absolute path to your ".hex" file in ''**File Source**'' block parameters :
