   * ATTENTION : **Channel** parameter has to be set to **__3__** as in the previous image. That's the only channel that allows access to the custom design.

+ * **Radio420 **
-  * Set CR1 value to 0 to enable the transmitter
+  * 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__
  * **Custom Register** (CR 1 & 4)
