[Elecraft] New Synth Observation...

[David Cole]

Hello all,
I noticed something about the new synthesizers...

I like to monitor the Ionosphere changes, using a program called
SBSpectrum.  This allows very, very, small changes in frequency to be
shown graphically.  Changes on the order of only a few parts of a HZ.

In the past, (Icom 756 PROIII), I had no issues...  Very smooth lines on
the graph, no steps, all very somooth.

With the old synthesizers, no issue, same thing, smooth lines.

With the new synthesizers, I now see a saw tooth stepped shape to the
trace.  As if the synthesizer is detecting a change in frequency, then
correcting for it in a single "largish" step.  Largish being a few
tenths of a HZ.  

Could someone comment on this change, either form Elecraft, or
elsewhere?  Is there a way to reduce the step size?
