Transceiver comprising a low power RF radio broadcast transmitter having means to modulate a transmitter carrier frequency with a baseband modulation signal as well as transmitter tuning means to vary said transmitter carrier frequency within an RF radio broadcast band. To secure that operation of said transmitter means will not cause interference to broadcast reception, said transceiver includes an RF radio broadcast receiver having a search tuning circuit being provided with channel selecting means for, in a receiving mode of the transceiver, detecting a free RF radio broadcast channel within said RF radio broadcast band carrying no RF signal exceeding a predetermined threshold level, said channel selecting means supplying tuning data defining said free RF radio broadcast channel to means for transmitting said tuning data to said transmitter tuning means for tuning said transmitter carrier frequency to said free RF radio broadcast channel in a transmitting mode of the transceiver.
