I have an ex Russian military variometer (actually I am told it's really a goliometer...), that I use in series with an LF loading coil. It's remote tunable with a geared motor drive. On MF I do not need the main loading coil to resonate the antenna, just the variometer, BUT, it has to be set to its very minimum inductance and the weather etcetera sometimes means even on minimum inductance there's too much. I don't want to try and butcher it, is there any trickery, even if there's a bit of loss, to reduce its inductance a bit and put the sweet spot within its normal adjustment range please? Thanks!
