Connection of the LIF converter (RX-only)
The LIF RX output of the transceiver connects to the IN port (TB1) of the
LIF assembly and the audio Line out (TB3) connects to the tip line-in of
the sound card. TB2 provides power (+12V). TB5 is not used for the RX-
only version. A jumper has to be placed on TB4 between 3-4 to bypass
the 7kHz high pass filter or between 4-5 to enable it.
Note: The transmit audio is still filtered with the existing filter inside the IC-
756. If the MDSR is properly configured the standard microphone can be
used to transmit, while the RX is processed through the computer.
For more details see “Lock to TXCR” the MDSR help menu.
