Understood. I learned the difference between the two when I stuck my foot in my mouth and got corrected.
Adjacent channel interference isn't usually a problem unless there is a great difference in signal strength between the two channels. There is often a highlighted red "a" before the callsign in a TVFool report as an adjacent channel warning.
According to the ATSC guidelines, you should be able to receive the weaker channel if the signal strength of the stronger channel is less than 33 dB more than the weaker channel.
