Claim Text:
1. A method, comprising: determining to transmit a radio broadcast transmission that carries audio data, using a radio transmitter circuit connected to a corresponding antenna of a mobile electronic device; detecting a change in transmission conditions; determining to adjust impedance matching between said antenna and said radio transmitter circuit, in response to the detecting a change in transmission conditions, to be in compliance with broadcast power level legislative regulations at a current regional position of the mobile electronic device; detecting an occurrence of one or more passages in said audio data, which have local volume minimums, in said radio broadcast transmission; placing operations for the adjustment of the impedance matching so that they occur during said local volume minimums of said passages, in response to said detecting said local volume minimums of said passages in said audio data carried in the radio transmission; and adjusting, during said occurrence of said one or more passages in said audio data, which have local volume minimums in said radio broadcast transmission, impedance matching between said antenna and said radio transmitter circuit to be in compliance with said broadcast power level legislative regulations at the current regional position of the mobile electronic device, in response to said detecting said local volume minimums of said passages in said audio data carried in the radio transmission, whereby interruption or distortion of the audio transmission caused by said adjusting, is less likely noticed.
