I have to believe that this one is at least to some extent referring to me as I am a huge fan of the x-lock. Anyone who thinks that their rig is a NBS device is dreaming. OTOH the reality is that the x-lock tends to make the drift w/i the TR7 manageable.
Anyone who understands the technology knows that all x-lock is doing is "bouncing" the freq around a small freq "slot" and clocking that against a more stable reference. The rig is more stable than letting the PTO "free run". That is only slowing the entire process to a point so that we humans do not notice it as much. No harm, no fowl. Just comments. 73 Ron WD8SBB --- On Thu, 8/25/11, Jim Shorney <[email protected]> wrote: > From: Jim Shorney <[email protected]> > Subject: [Drakelist] Santa Claus, the Easter Bunny, and drift-free modern > radios > To: "[email protected]" <[email protected]> > Date: Thursday, August 25, 2011, 8:56 PM > > Some days I am more easily amused than other days. > > http://www.k0to.us/HAM/FT1000MP/Temperature%20Stabilized%20FT1000MP%20REF%20oscillator_files/Temperature%20Stabilized%20FT1000MP%20REF%20oscillator.htm > > What led me to the above link was a discussion of drift in > the IC-706 radios on another list.
