INTRODUCTION
This section explains the basic programming procedures for the RCI-2950/2970 amateur 10 meter mobile transceiver.
FREQUENCY SELECTION
Frequency selection in the RCI-2950/2970 can be accomplished using three of the following methods:
1. The first method of frequency selection is through the use of the (Shift) key and the and
arrows. To accomplish this, press the button until the cursor arrow is positioned under the digit of the frequency that
is to be changed. Then use the arrow to increase the number. If a decrease in frequency is desired, press the
arrow. Perform the steps described above for each digit of the frequency until the desired frequency is dispIayed in
the LCD display window.
2. The second method of frequency selection is accomplished using the button and the frequency select knob located
above the microphone jack. Use the SHF button in the manner described above to select the digit to
be changed. Then proceed to rotate the frequency select knob clockwise to increase the frequency. Rotate the frequency select
knob counterclockwise to decrease the frequency.
3. The third method of selecting the operating frequency of the radio is through the use of the button and the channel
Up and Down button located on the microphone Frequency selection by this method is accomplished in the same manner as with
the and arrows on the key pad. The only difference is that the channel Up and Down buttons on the
microphone are used.
While in receive mode, once a signal has been detected on a particular frequency, it may be necessary to slightly change the
frequency to provide the best audio through the speaker. This can be accomplished by rotating the clarifier control to vary the
frequency by ± 0.5 kHz. After this fine tuning has been accomplished, press the button to lock in the frequency at the
point of best reception.
FREQUENCY SCANNING
Frequency scanning can be achieved using one of two methods: the first method involves the scanning of pre-programmed
memory channels; the second method will permit the user to scan all frequencies between a preset upper and lower scan limit.
Both methods of frequency scanning follow.
All Frequency Scanning
To allow All Frequency Scanning, one must first program the upper and lower scanning limits. The scan limits are simply the
highest and lowest frequencies that will be scanned. To program these limits, perform the following steps:
1. Press the (Program) key.
2. Press the key. (“PRG SCAN+” should appear in the lower right corner of the display window.
