1. Connect the coupler to the SG-2000.
2. Connect the coupler dummy load to the SG-230 antenna jack.
3. Turn on the SG-2000 and the SG-230.
4. Set the SG-2000 to the CW mode.
5. Key the PTT switch on the microphone and look at the light bulb. The light should turn on if the coupler has
completed its' tuning cycle and if the radio is transmitting.
6. For further testing, follow steps 4 through 12 of the radio test procedure.
Note: The light bulb might not turn on immediately if the coupler has not yet been tuned for the frequency of the
transmitter. The output power (light-bulb brightness) is greatest when the coupler is properly tuned.
The wattmeter is a test instrument that can be connected in between the transceiver and the antenna to show
exactly how much power is being output by the transceiver.
The SWR meter is used to measure the standing-wave ratio of an antenna at a given frequency. If the
transceiver has a built-in SWR meter, it will automatically show the SWR. If the SWR meter is in a separate unit or
is contained in an antenna tuner, you might need to tweak a few knobs or settings to get the accurate SWR.
