No transmitter has infinitely steep stop bands in frequency space. There is ALWAYS bleedover, proportional to the main signal strength. Plus some of those transmitters WILL be badly engineered, or will drift due to aging. It IS just plain stupid to put a strong signal next to a band you know contains weak signals. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
