[time-nuts] Leakage, tinySA

[Dan Kemppainen]

Dana,

Just an FYI. Apparently, there are knockoff clone copies of the TinySA 
out there. (Yes, making a knockoff clone of a $50 spectrum analyzer is a 
thing, go figure!)

Apparently, these have substandard performance, and a host of 
issues/concerns. I ran into this on the TinySA web site. They have some 
hints on how to detect if you have a clone or not. Might be worth 
looking into to see if you have a sub-par copy.

Dan
