Hello,Newbie question, please:
If I see a well defined, and relatively large, peak in the spectrum display(s), but never hear any
actual conversation when tuned to that peak, what is the meaning of the peak, probably ?
Very prevalent situation for me on NFM and also AM.
Lots of examples of this on my displays; peaks with no conversation.
Are they just (always) transmitting a carrier (NFM & AM ?), even though they are not using it
for any msg. at the moment ?
If so, why waste all the power, and not transmit when they actually have something to say ?
If anyone could explain this a bit, would be appreciative.
