A method for monitoring interference, the method comprising: receiving, at a radio modem , at least one radio data signal from a transmitting device across a particular one channel of a plurality of channels, the particular one channel associated with a dedicated radio link between the transmitting device and the radio modem; transmitting the at least one radio data signal to a demodulator of the radio modem to generate a decoded primary signal ; characterized by : producing a plurality of data samples from a sampling of the at least one radio data signal by a processor of the radio modem, the plurality of data samples comprising raw analog-to-digital samples of the at least one radio data signal sampled prior to demodulation and representing a complete sum of all signals within the particular one channel of a plurality of channels; and transmitting the raw analog-to-digital samples in replacement of demodulated data associated with the at least one radio data signal transmitted, as a representation of the at least one radio data signal present at an input to the radio modem, from the radio modem to a user communications device for determining whether the at least one radio data signal is subject to a voice signal interference based on an audible rendering of the representation on the user communication device, wherein the audible rendering is of an audio waveform of the voice signal. receiving, at a radio modem , at least one radio data signal from a transmitting device across a particular one channel of a plurality of channels, the particular one channel associated with a dedicated radio link between the transmitting device and the radio modem; transmitting the at least one radio data signal to a demodulator of the radio modem to generate a decoded primary signal ; characterized by : producing a plurality of data samples from a sampling of the at least one radio data signal by a processor of the radio modem, the plurality of data samples comprising raw analog-to-digital samples of the at least one radio data signal sampled prior to demodulation and representing a complete sum of all signals within the particular one channel of a plurality of channels; and transmitting the raw analog-to-digital samples in replacement of demodulated data associated with the at least one radio data signal transmitted, as a representation of the at least one radio data signal present at an input to the radio modem, from the radio modem to a user communications device for determining whether the at least one radio data signal is subject to a voice signal interference based on an audible rendering of the representation on the user communication device, wherein the audible rendering is of an audio waveform of the voice signal. producing a plurality of data samples from a sampling of the at least one radio data signal by a processor of the radio modem, the plurality of data samples comprising raw analog-to-digital samples of the at least one radio data signal sampled prior to demodulation and representing a complete sum of all signals within the particular one channel of a plurality of channels; and transmitting the raw analog-to-digital samples in replacement of demodulated data associated with the at least one radio data signal transmitted, as a representation of the at least one radio data signal present at an input to the radio modem, from the radio modem to a user communications device for determining whether the at least one radio data signal is subject to a voice signal interference based on an audible rendering of the representation on the user communication device, wherein the audible rendering is of an audio waveform of the voice signal. <EOS>
