Using high K resistance potentiometers in mixer?

[142victoria]

Final question; Rayma Given a choice to buy pots shall I go with using 10K linear pots with 10k input resistor ( to give lower noise?) or should I stick to the using 10k log pot and 100K input resistor?

Use the 10k resistor and a 10k linear pot, much better.

Thank you all for making my mind up.

adding to all already said that lower impedance may also reduce external RF and noise suceptibility...
