5. Key the PTT switch on the microphone and talk into
the microphone. Notice that the light turns on when
you talk.
COUPLER TEST PROCEDURE
1. Connect the coupler to the radio.
2. Connect coupler light bulb load to Smartuner coupler antenna
out-put.
3. Turn on the radio and the Smartuner coupler.
4. Set the radio 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 & 5 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. This test will
ensure that the radio and coupler are working properly.

5 Theory of Operation
The MAC-200 tuner is built around two basic coupler networks,
the L & PI. Note that the L network as viewed from the transceiver
may be configured as either “C in” or “C out,” whichever is
required by the load. In either case, the end of the network
containing the shunt C element will be the higher impedance end
of the network.
L Networks:
