Low frequency tunable inductors
 

Found some notes in last Radcom (Technical topics by G3VA) about
saturable core inductors. Surprising little has been discussed about
the matter recently, but I suppose it could be a good idea to use for
LF experiments when tunable cores are a problem, he also mentions
using two MOSFETs to form a variable capacitor with maximum
capacitance of 1500pF
