Claim:
1. A method of communicating with an entity having an unknown selection of radio communication channel setting, comprising: detecting an unauthorized aircraft comprising one of a plurality of superheterodyne communication architecture systems, each of said superheterodyne communication architecture systems comprising a band pass filter type with a first frequency range associated with aircraft communications bands and one of a plurality of different intermediate frequency filter types each associated with different superheterodyne radio architectures, wherein each of said band pass filter type and ones of associated said plurality of different intermediate frequency filter types are respectively associated with each of said plurality of superheterodyne communication architecture systems; determining the unauthorized aircraft's location and bearing using an aircraft location detection system; selecting a first of said plurality of superheterodyne communication architecture systems comprising said band pass filter and a first intermediate frequency filter type of said plurality of different intermediate frequency filter types; selecting at least a first frequency or channel and a second frequency or channel configured for respectively broadcasting a first omnidirectional signal from a first omnidirectional antenna and a directional signal from a directional antenna, wherein said first frequency or channel and said second frequency or channel is selected based on one or more design parameters of said first of said plurality of superheterodyne receiver architecture systems, said one or more design parameters of said first of said plurality of superheterodyne receiver architecture systems comprising frequencies which said first of said plurality of superheterodyne receiver architecture systems will not reject using said band pass filter type or said first intermediate filter type of said plurality of different intermediate frequency filter, said first frequency or channel and said second frequency or channel are also determined based on a mixer product that results in a first intermediate frequency that will pass through said first intermediate frequency filter type, wherein said first intermediate frequency is further determined based on determining a frequency range separation between said first frequency or channel and second frequency or channel by differencing said first frequency or channel from said second frequency or channel to determine an absolute value difference that defines said first intermediate frequency that is equivalent to said frequency range separation; broadcasting said first omnidirectional signal from a omnidirectional antenna; orienting a beampath of said directional signal towards said unauthorized aircraft and maintaining said aircraft within said beampath of said directional signal during a period to transmit a message to said unauthorized aircraft; and modulating and transmitting said directional signal with said message for said period to transmit said message so as to mix said first omnidirectional signal and said directional signal at said unauthorized aircraft's location during said period to transmit said message.
