[Elecraft] KRX3A sensitivity

[Conrad PA5Y]

Hello all.

I have a dual diversity Xpol EME system for 2m and a dual coherent transverter. I am trying to calculate if I have enough gain available in the transverter to split the output 4 ways with a loss of approximately 6dB.

The K3S has an MDS of -138dBm in a 500Hz bandwidth which is approximately 9dB noise figure with preamp 1 switched on. Does the KRX3A have a an independent preamp1? I know that the preamp2 is a shared resource. What about preamp1?

Many thanks in advance.
