Re: FM or TV Spectrum/Frequency?
FM always has a spike at 19KHz - so this isn't FM.
I think I recall people on this forum saying that analogue TV audio has a spike at around 16KHz, but as I live in the UK (where TV audio has been digital for the past 20 years), I don't know anything about that. Hopefully someone that does know will confirm that.
