[time-nuts] HP3325B as LO for a transceiver or receiver?

Hi.

Usually on a crowded band, to be nice to the RF neighbours (often
ourselves!)  Irrespective of the "mode" used, and/or getting the "best"
performance (small signal sensitivity) from a receiver.

Also, when multiplying/mixing up to microwave frequencies, again for a
clean signal.

The OP wanted to use it as an external reference signal for a Kenwood
radio (from memory.)  But how much of it's existing phase noise
signature is from the "reference", and how much from the other PLL's and
synthesizers it has internally may make what a Time Nut might regard as
a noisy external reference perfectly OK to use.

It's something that does interest a lot of people (especially VHF and up
DX'ers) where some popular makes of rig are very much worse than others!

However, few have the kit needed to make definitive "measurements", or
the ability to understand them "in the real world".  (Me included!)
