Small mono transmitter of minimal send level in band 88-108MHz (CCIR) or in66-77MHz (OIRT). Two stage circuit with bipolar transistors works as wirelessmike or transmitter low-frequency signal from generator, eventually any other audiosignal which is on entry modified for required level. Power supply9V/15mA. Equipment is designated exclusively for need of school education as ainstrument demonstrating principle of frequency modulation and is not recommended for other use. User get's him self in to a conflict with regulations in force. Thanks to frequency range it is possible that broadcasting signal is received on any usual FM receiver. By reason of stability it is recommended to put whole construction including 9V blockbattery in all-metal box, user type AH 106 (it's not part of delivery).
