Default Re: Building a Radio-Goniometer - inductance values?

I made one (again out of interest) some years back. One interesting application of these is as a variable phase-shifter. Connect one input to the source and another with a simple R/C network to give a 90 deg shift. The output is then continuously variable in phase with reference to the source.
