[AMRadio] Ensuring the scope is well within limits of calibration

[Robert Bethman]

I use a very good VXCO.

I have additionally built a GPS Frequency Standard.  [  GPSDO ]

<http://www.techlib.com/electronics/GPSstandard.htm>

Designed by Mr. Wenzel!  Uses a Trimble Resolution T Board with an active GPS Antenna that receives between 10 to 12 satellites at the minimum.

This is how I keep from having to send my oscilloscope in to have it calibrated.  I essentially maintain my own calibrating ability.
