Frequency selection for the RCI-2950 DX / RCI-2970 DX is simple. Select a desired operating
frequency by rotating the Frequency Selector, or using the (σ) Up and (τ) Down buttons on the front
panel or the microphone. Press the LOCK button to lock into the selected frequency. This will disable
the Frequency Selector and the up/down buttons on the front panel and the microphone. Repressing the
LOCK button unlocks the frequency. Use the SHF button to step frequency in either 100 Hz, 1 KHz, 10
KHz, 100 KHz or 1 MHz increment when you select a band segment. The frequency step is indicated by
a small triangle directly under the corresponding digit on the frequency display.
3.3.2 MODE SELECTION
To select an operating mode on your RCI-2950 DX / RCI-2970 DX, simply rotate the MODE selector
and place it in the desired operating mode position.
FM/AM/USB or LSB modes are for your voice communications. In the CW position, you can transmit
CW if you have connected an external key to the accessory jack provided on the back of the radio. In the
PA position, the transceiver can be used as a Public Address system. Before operating in PA mode, you
must first connect a PA speaker (8 ohms, 5 Watts) to the jack located on the rear panel.
3.3.3 RF POWER CONTROL
This feature allows the adjustment of the RF output power continuously for the RCI-2950 DX (AM 1W
to 10W; SSB: 10W to 25W), and (AM: 8W to 50W; SSB: 18W to 100W) for the RCI-2970 DX.
3.3.4 RECEIVE SCANNING
Receive scanning allows you to find active frequencies in the entire band segment. To begin scanning,
slowly turn the Squelch control clockwise until the receiver noise disappears. Press the Scan button. The
unit should start scanning from the lower to the higher frequencies. Pressing the Scan button again will
change the direction of scanning. Each time you press the Scan button, "SCAN+" or "SCAN-" will
displayed on the LCD display. The radio will stop on any active frequency for the entire duration of the
transmission. When the transmission stops, the RCI-2950 DX / RCI-2970 DX will wait approximately 2
seconds before it resumes scanning. If you want to deactivate Scan mode while it is scanning, press the
MAN (manual) button or turn the Squelch control counterclockwise until you hear the receiver noise.
The Manual button will disable Scan function.
