Abstract: A portable device to be carried by a reporter and coupled to a telephone line to a location from which the reporter wishes to transmit a report to a broadcast station to be broadcast live has a casing with a microphone (1) for voice input, a tape input (2) for receiving a tape signal and a monitor (3) for providing acoustic signal to the reporter.The device has signal conditioning circuitry including voice control gain adjustment (20) and amplification (5) for providing a signal to be transmitted by the telephone line in a form suitable for broadcasting. The device is coupled to the telephone line by a hybrid transformer arrangement (7 to 14) which serves to cancel unwanted components of the signal to be sent down a telephone line from that to be received from the telephone line. The device is portable and has its own power supply in the form of batteries or connections for an AC mains auto supply.
