Quiet spot detection for FM transmission

A method comprising:

• evaluating at least a signal strength and signal to noise ratio for each of a plurality of frequencies of a frequency band, wherein evaluating the signal strength and the signal to noise ratio for each of the plurality of frequencies further comprises
• if a local receiver antenna is operatively coupled to a receiver port, tuning a local receiver to each of the plurality of frequencies to receive signals of each of the plurality of frequencies that are being broadcast and that are received by the local receiver antenna,
• if the local receiver antenna is not operatively coupled to the receiver port, tuning the local receiver to each of the plurality of frequencies to receive the signals of each of the plurality of frequencies that are being broadcast and that are received by a local transmitter antenna, and
• evaluating the signal strength and the signal to noise ratio for each of the plurality of frequencies based at least in part on signals received by the local receiver antenna or the local transmitter antenna;
• determining a quiet spot frequency from the plurality of frequencies, based at least in part on the evaluated signal strengths and signal to noise ratios;
• and
• transmitting signals at the determined quiet spot frequency.

A method comprising:

• tuning a device to each of a plurality of frequencies in a frequency band to receive signals of each of the plurality of frequencies that are being broadcast, wherein tuning to each of the plurality of frequencies further comprises
• if a local receiver antenna is operatively coupled to a receiver port of the device, tuning the device to each of the plurality of frequencies received by the local receiver antenna, and
• if a local receiver is not operatively coupled to the receiver port of the device, tuning the device to each of the plurality of frequencies received by a local transmitter antenna;
• evaluating at least signal strength and signal to noise ratio for each of the plurality of frequencies, based at least in part on said tuning;
• and
• determining a quiet spot frequency from the plurality of frequencies, based at least in part on the evaluated signal strengths and signal to noise ratios.
