Step 5.
Plug both the microphone connector and the external speaker jack into your
transceiver.
Adjusting the Receive Volume of Your Transceiver
To adjust the receive volume of your transceiver to the proper level (or to confirm that it
is already set at the proper level), do the following:
Step 1.
Turn ON your computer (with your transceiver OFF),
Step 2.
Start your terminal program,
Step 3.
Turn ON your MT1200,
Step 4.
If not already done, set the MT1200’ baud (ABAUD) and CALLSIGN,
Step 5.
Turn ON your transceiver and open the squelch control (turn it fully counter-
clockwise),
Step 6.
Slowly turn the transceiver’s receive volume up until the RCV LED (receive
indicator) on the MT1200 lights up (turns ON),
Step 7.
Increase the transceiver’s receive volume control slightly above the point at
which the MT1200’ RCV LED lit up (turned ON),
Step 8.
Slowly turn the transceiver’s squelch control clockwise until the MT1200’ RCV
LED goes OUT (turns OFF),
Now the receive volume control on your transceiver is properly adjusted for sending
signals to your MT1200.
Your MT1200 is now installed and ready to use. You may now go to the “Getting
Started” chapter, to learn how to do the basic operations with your MT1200.
If you do not see the receive LED light, check the cabling between the radio and the
MT1200. Also, until it has been initialized from the computer, the MT1200 will not show
ANY indication of receiving.
If you connected to a fixed level (unsquelched) receive audio from the radio, the receive
LED on the MT1200 may remain on all of the time. In this case, set the parameter CD to
SOFTWARE. Then, the receive LED will not light until valid packets are heard. (see CD
in the commands section)
Transmit level adjustment
The 1200-baud data drive level (transmit audio voltage, TXA) from the MT1200 to your
radio is adjusted digitally, using your keyboard and the transmit level (XMITLVL) or the
40
