If you have a Thunderbolt and have it configured for an external oscillator, Lady Heathers' "&a" autotune command will determine and display the oscillator EFC sensitivity. It works by setting the DAC voltage a few millivolts high, measuring the frequency, setting the EFC a few millivolts low, measuring the frequency, and calculating the gain value in Hz/volt. The process takes a couple of minutes. Typical values for the standard Tbolt oscillator are around -3.5 Hz/volt.
