If you have a cheap multimetre with frequency counter. In some circumstances they can pick up wirelessly if higher voltages are a concern. I clocked wireless driven oscillator used in simple sec experiments at 305 KHz. It wasnt untill I went to pack up my multimeter that I realised I forgot to plug it into the circuit. I had the bananna leads plugged into the meter. Perhaps they were acting like antenna.

Im not convinced that it was quarter wave resonant due to the need for virtual grounding in certain places but I am still learning.
