Anti-log Pot track puzzler?

[Yorkie]

Hi Lawrence.

Thanks for your coments.

I've tried to do this again, with the same results. I've attached a diagram showing how I set the 50k linear pot up, with an 8k2 resistor from the slider to the top of the pot. I then put an ohmmeter across the slider and bottom of the pot and tracked the results, which resulted in a perfectly linear line - not an anti-log curve. The line was below that of a 50k linear pot on its own, and the total resistance was 42 k - not 50k.

What I want it to behave like is a 50k antilog pot in the role shown as in the circuit diagram.

You could say that I've still lost the plot - no surpises there then!

Hope the crude diagram makes sense, even though the results seem not to.
