Congratulations on your purchase of an RCI-2950DX/2970DX-150 10
and 12 meter dual band amateur radio. Your RCI-2950DX/2970DX-150 is
designed to provide trouble-free service and state-of-the-art
communications, incorporating many useful features and functions in the
10 and 12 meter dual band radio. Please read this manual thoroughly to
ensure proper performance.
IMPORTANT
To operate this radio, you must possess and amateur radio operator's
license issued by the FCC. Operation of this unit without proper
licensing is ILLEGAL and can result in severe penalties.
NOTE
The manufacturer is not responsible for any radio or TV interference
caused by unauthorized modifications to this equipment. Such
modifications could void the user’s authority to operate this equipment.
Unpacking

Chapter 3 Installation
Chapter 4 Operation
The RCI-2950DX/2970DX-150 is easy to install. All necessary parts (less
the antenna and coax cable) have been included to facilitate installation.
Transceiver Mounting
Choose a suitable location for the transceiver that will allow easy access
to the front panel as well as proper air circulation to the back of the unit.
If you are installing the unit in a vehicle, attach the mounting bracket first,
then attach the transceiver to the mounting bracket using the hardware
provided. Before making any electrical connection, ensure that the
transceiver is turned off and the vehicle's battery is disconnected.
Power Connection
The transceiver operates off of any 12 to 13.8 VDC source. Beware of
voltage drops caused by operating from Cigarette Lighter Plugs or long
DC wire runs. Sometimes it is best to connect direct to the battery for
best RF output and Tx audio quality
NOTE
The condition of a vehicle's electrical system can affect the operation of
your RCI-2950DX/2970DX-150. A low battery, worn generator/
alternator, or poor voltage regulator will impair performance of the unit
as well as the vehicle.
If an AC power supply is used with your radio, it must be regulated and
rated for at least 7 Amps continuous for the RCI-2950DX and 20 Amps
continuous for the RCI-2970DX-150. Low voltage while under load will
cause reduced receiver gain and low transmitter output with possible
distortion and splatter.
CAUTION
Voltage above 15 VDC will damage the unit. Be sure to check the
source voltage before connecting the power cord.

Front Panel
1. FREQUENCY SELECTOR: Used to set the desired transmit and receive
frequency. The frequency is digitally displayed in the LCD window next
to the selector. The FREQUENCY SELECTOR knob next to the LCD
display, allows changing each digit on the frequency display by first
placing the frequency display cursor (using SHF button) below the
desired digit and then turning the selector knob.
2. RF POWER CONTROL: This control adjust the Transmitter’s RF power
output level.
3. MIC GAIN CONTROL: This feature adjust the microphone gain for the
transmit and PA modes. Experiment with this control for the setting that
will provide best audio quality. Avoid over-modulation, which causes
interference to adjacent stations and “splatter”.
4. ON/OFF VOLUME CONTROL: Turn clockwise to apply power to the
radio and to set the desired listening level.

5. SQUELCH CONTROL: This control is used to control or eliminate
receiver background noise in the absence of an incoming signal. For
maximum receiver sensitivity, it is necessary that the control be
adjusted only to the point where the receiver background noise is
eliminated. Turn fully counterclockwise and then slowly clockwise until
the receiver noise just disappears. Any signal to be received must now
be slightly stronger than the average received noise. Further clockwise
rotation will increase the threshold level that a signal must overcome in
order to be heard. Only strong signals will be heard at a maximum
clockwise squelch setting.
6. RF GAIN CONTROL: This control is used to reduce the receiver's frontend gain when receiving strong signals.
7. CLARIFIER CONTROL: Allows variation of the receive frequency above
and below the selected receive frequency as shown on the display.
This control is intended primarily to tune in SSB signals when
communicating with several stations that may not be exactly on
frequency. It may also be used to optimize AM/FM signals as
described in the operating procedure paragraph. The clarifier can adjust
the receive frequency ±2.5KHz but does not affect the transmit
frequency or the frequency display.
8. MODE SWITCH: This switch allows you to select one of the following
six operating modes: FM, AM, USB, LSB, CW and PA.
9. NB/ANL BUTTON (NB/ANL): The noise blanker (NB) is very effective in
eliminating repetitive impulse noise such as ignition interference. In the
ANL position, the AUTOMATIC NOISE LIMITER also limits noise at the
receiver audio stages.
10. ROGER BEEP BUTTON (R.BEEP): This switch activates the ROGER
BEEP circuit, when its function is selected. When enabled, the radio
automatically transmits an audio tone each time you release the PTT.
This indicates the end of each transmission so that stations who may
be having trouble receiving will know that you have finished
transmitting. This feature is sometimes used in weak signal conditions
or other special circumstances. We discourage use of this feature in
normal operation, as it can be annoying to other operators.
11. SPLIT BUTTON (SPLIT): Enables the offsetting of the transmitter
frequency by up to ± 2 MHz (programmable) for FM repeater
operation.
12. PROGRAM BUTTON (PRG): Used to pre-program operating or
scanning frequencies into memory. See the OPERATION section of this
manual for details.
13. MANUAL BUTTON (MAN): Used to return the unit to manual mode.
14. SHIFT BUTTON (SHF): Determines which digit will change when
changing frequencies, by placing a “cursor” under the desired digit.
Allows frequency to be changed in 100 Hz, 1KHz, 10KHz, 100KHz and
1 MHz increments.
15. DIM BUTTON (DIM): This button adjusts the display backlighting in
four different steps to best match the ambient light.
16. SWR BUTTON (SWR): Used to check relative SWR.
17. SCAN BUTTON (SCAN): Used to enable the scanning of frequencies.
See the PROGRAMMING and SCANNING section of this manual for
detailed information on using the scan control.
18. MEMORY BUTTON (MEM): Used to program often used frequencies
in memory. Detailed information on how to use this control is provided
in the PROGRAMMING section of the manual.
19. ENTER BUTTON (ENT): Used to program frequencies in memory.
See PROGRAMMING section.
