In order to achieve maximum radiated power, it is important that your antenna be in good condition,
properly adjusted and matched to your transceiver. The built-in SWR (Standing Wave Ratio) meter
allows you to measure your antenna condition. To operate this function, connect your antenna to the
transceiver antenna connector, set the mode switch to AM and adjust the MIC GAIN to minimum.
Select a frequency near the middle of the band you plan to use most. Activate the SWR function and
press the PTT button on the microphone. A bar on the meter is an indication of the antenna matching. If
there is no bar, it indicates that your antenna system is perfectly matched. The fewer bars, the better
matched. If several bars appear, your antenna needs adjusting.
3.3.9 CTCSS - OPTIONAL
The RCI-2950 DX / RCI-2970 DX can operate with CTCSS frequencies for accessing repeaters, with an
optional CTCSS (Continuous Tone Coded Squelch System) encoding device installed.
3.3.10 PROCEDURE TO RECEIVE
(1)
Be sure that power source, microphone and antenna are connected to the proper connectors before
going to the next step.
(2) Turn unit on by running VOL knob clockwise on transceiver.
(3) Set the VOL to a comfortable listening level.
(4) Set the MODE switch to the desired mode.
(5) Listen to the background noise from the speaker. Turn the SQ knob slowly clockwise until the noise
just disappears. The SQ is now properly adjusted. The receiver will remain quiet until a signal is
actually received. Do not advance the control too far or some of weaker signals will not be heard.
(6) Set the CHANNEL selector switch to the desired channel.
(7) Set the RF GAIN control fully clockwise for maximum receive gain.
(8) Adjust the CLARIFIER control to clarify the SSB signals or to optimize AM/FM signals.
3.3.11 PROCEDURE TO TRANSMIT
(1)
Select the desired channel of transmission
(2) Set the MIC GAIN control fully clockwise.
(3) If the channel is clear, depress the push-to-talk switch on the microphone and speak in a normal
voice.
