The two RX channels on each daughtercard also share a common LO in internal mode. However, the two daughtercards in the N310 do not share TX or RX LOs unless they are provided externally. > 2) For an external LO signal, what power level should be used?

The external LO is 2x, so max RF frequency using the external LO is 4 GHz.. Thank you for pointing out the omission. We will add this information to the N300/N310 KB page. 3) For the MPM, the instructions indicate that you can either update the > entire file system (on SD card) or you can recompile MPM from source.
