nanoVNA test board

[Alex Fraser]

I soldered the 6 SMA jacks on the little nanoVNA test board kit.   It 
was good soldering practice and a way to assess my current soldering 
abilities.  I went fairly well.  As the fumes from the flux whirled 
around my head I had some thoughts...

If a made an adapter for the SMA jack so I could plug it into one of 
those plastic push pin breadboards, then could I expect any good reading 
with the nanoVNA?  Would I calibrate connected to the breadboard for 
open, jumpered for short and a 50 ohm resister pushed for resistance? 
What would be the frequency limits for using those breadboards?  Are 
there any tricks as to which way you use the rows of pin holes to plug 
in components?
