Noise figure RFX400 [SEC=UNCLASSIFIED]

Has anyone measured the noise figure of the RFX400 receiver? I’m
looking at modifying one to operate in the high VHF band, 136 - 173 MHz
and I’d like to know if its going to perform better then the receivers I
already have. From what I’ve read the modification will involve
changing the local oscillator semi to a ADF4380-8.

Any information will be appreciated.
