Just want to add that the RRM is known to load the VCOs and thus 
affecting their performance. The results would be different if the 
inputs of the RRM were buffered. One could add an Op Amp to each 
input or (if I'm not mistaken) 2 Analogue Solutions' MX224 
Mixer/Buffer Modules. Obviously the latter is not very economical.
