Hi Mark:
It's not clear to me why pager testing requires such good phase noise. I wonder if some of the amateur modes also have
that need?
Maybe WSPR?

I have done a study of how good it needs to be on my website:

The question that remains begging here from the original post (maybe off
topic ?) is how low a phase noise does he really NEED in this
application? We here at time-nuts tend to think in the 10e-12 minutia
area, but In this application ( a HF Communications receiver) the 3325B
may be "good enough" that PN wont really be an issue as a practical
matter. Don't see who the original poster is from this snippet but a
possible better place to get a "practical" answer might be over on the
EEVBlog?

Hi Chris:
The HP 8648 Signal Generator was developed to have low phase noise
that was needed for testing pagers.

Could I use my HP3325B locked to a Trimble Thunderbolt GPS disciplined
10MHz oscillator as the master LO of my Kenwood TS-590S transceiver
that has a LO at 15.6 MHz, or is the phase noise too great? My VK3HZ
gps disciplened LO replacement died recently, I may be able to repair
it but as they are no longer available I am looking at alternatives to
achieve a very stable frequency. Thanks
