There is a lot of differences between SRD's in terms of flicker / shot
noise. I'd bet they changed the multiplier design.

I have a question for the list that I'm sure Corby can address but
perhaps someone else can explain as well.
Corby notes that this mod has only been effective with late series A3
modules. My question is: what change did HP make to the A3 module
(early to late) that affects the mod Corby is making? I do not own a
5065 and the the only manual I have found on the web omits the pages
related to the A3 multiplier so I'm not sure of it's exact function: I
assume it generates the phase modulated 6.8 GHz?
