    The MFJ-1708B-SDR T/R switch uses a relay, which switches from transmit to receive mode. When no power is applied to the unit, it is in the transmit mode. Once power is applied the relay switches on and the unit is in receive mode. When the unit senses RF or the control line is grounded from a keyer or PTT switch, it switches the relay off and the unit is in transmit mode. The delay adjustment allows you to change how fast the relay switches back to the receive mode. It is adjustable from 0 to 2 seconds.

    The MFJ-1708SDR T/R Switch requires 12 VDC or 110 VAC with MFJ-1312D power supply.
