Thanks all for the ideas ... I have a couple of potential solutions.

This isn't a direct solution but it looked interesting if someone wants
to try it - Harry Lythall's accidental discovery of an LM317 series
voltage regulator as an RF oscillator at low HF.

Use a toroidal core and/or a multiplying rectifier and the voltage could
be sizeable.
