Does anyone know the approximate RF frequency that the OneteslaTS operates on? (i.e., the resonant frequency of the secondary, NOT the interrupter's audio frequency). Is it below or above -or in- the AM broadcast band?
Thought I'd ask before spending a lot of time searching with a general-coverage receiver... just wondering where to start looking.
I'm assuming the interrupter modulates the RF, and one should be able to hear the audio on a radio receiver tuned to the correct frequency... yes? no?

OneteslaTS RF Operating Frequency?

Re: OneteslaTS RF Operating Frequency?
Never mind... I found it. I found another thread mentioning 270 kHz, so I started looking there. Mine is running at around 275 kHz, and on a general coverage receiver tuned to that frequency, set to AM mode, the signal from the coil can be heard. It sounds exactly like the sound produced by the spark (no surprise there), and the fidelity seems to be about the same as the "spark-speaker". Sounds pretty neat when OMD files are played. Next, I'll have to check the propagated range of the signal...

Re: OneteslaTS RF Operating Frequency?
Found the third harmonic of my coil around 835 kHz, which makes the actual operating frequency around 278.3 kHz. Sound about right to everybody?
