[Elecraft] K2 Facilitating Thermistor Calibration

[David Woolley]

I'm getting close to the point at which I populate the thermistor board 
and I came across an article saying that the quarter watt resistor was 
deliberately not an eighth watt in order to make it easier to change it 
to calibrate the board.  Has anyone devised good ways of making it easy 
to adjust, e.g. by using a variable, or using a header, so the through 
hole joints don't have to be remade? Is there enough clearance to do 
something like this.

(As an aside, it would have been nice to have done the correction in 
firmware, so that you linearise the calibration curve, but I guess that 
would have needed another microcontroller hanging off the AuxBus.)
