[Elecraft] [KX3] A Comparative Performance Assessment (of Aftermarket KX3 Heatsinks)

[Don Wilhelm]

Al,

Without knowing the specifications and most recent calibration data for 
the measurement equipment as well as the complete setup info, 
environment info and details of how the procedure was performed, I would 
suggest that 1 degC could be within the range of 'measurement error'.

For example:
If the ambient environment was not precisely controlled, there could be 
as much as a 2 degC variation in the ambient temperature as well.  If 
performed in an air conditioned space, consider the hysteresis in the 
thermostat controlling the AC (if the thermostat is set for 72 degF, it 
may come on when the room temperature reaches 74 degF and turn off when 
the room temperature drops to 70 degF - it all depends on the 
characteristics of the thermostat).

So without that kind of seemingly unrelated details, small variations in 
the measurements can be disregarded.

73,
Don W3FPR
