User manual ICOM IC-R1

[. . . ] This compliance is based on conformity with the ETSI specification prETS300 684 (EMC product standard for Commercially Available Amateur Radio Equipment). PRECAUTIONS RINDOOR USE ONLY!NEVER expose the IC-R1 or AC adapter to rain, snow or any liquids. AVOID using or placing the receiver in areas with temperatures below ­10°C (+14°F) or above +50°C (+122°F). AVOID placing the receiver in excessively dusty environments or in direct sunlight. [. . . ] Broadcasting, amateur bands, citizens band, air band, etc. AM-wide mode is used for clear audio reception. Signals however, may be received with interference. FM narrow 5. 5 kHz/­6 dB medium 5. 5 kHz/­6 dB AM wide 12 kHz/­6 dB narrow 2. 2 kHz/­6 dB USB Shortwave broadcasting, amateur bands, etc. Use USB for normal SSB reception; LSB is not normally used. SSB LSB 2. 2 kHz/­6 dB normal 2. 2 kHz/­6 dB CW narrow 500 Hz/­6 dB (option) 150 kHz/­6 dB Morse code communications. Use this mode to receive radio-teletype, etc. TV and FM broadcasting cannot be accessed in FM mode because their signals are too wide. WFM 13 RECEIVE FUNCTIONS 4 s Squelch function The IC-R1 has 2 types of squelch, noise squelch and S-meter squelch. Noise squelch: Only acts on noise; has good sensitivity. It can be adjusted for reception of weak signals. Strong signals exceeding a certain level will always cause the squelch to open. S-meter squelch: S-meter squelch does not open for weak signals but can be adjusted to open for signals over a wide range of strengths. Once you have selected a threshold point in a range, the IC-R1 will open for all signals above this point. To adjust the squelch, rotate [SQUELCH]. · Clockwise rotation closes the squelch (sets the threshold point higher); counterclockwise rotation opens the squelch (for reception of weak signals). S-meter squelch threshold Noise squelch threshold (not available in SSB, CW, WFM and AM narrow modes) · Signals below the S-meter level are muted. When [SQUELCH] is rotated past center, the S-meter shows the signal strength needed to open the squelch. S 1 3 5 7 9 +20dB +60dB SIGNAL s Functions for FM D Center indicator FM signals have a wide bandwidth which makes them easy to receive. However, you may be tuned off-center resulting in audio distortion. 8-digit memory names are programmed into all 1000 channels and 5-digit bank names are programmed into 20 user banks for convenient recall and organisation of frequencies. Moreover, memory channels can store mode information, a tuning step, and ATT (attenuation) information. NOTE: When memory channels without information (blank channels) are selected, the frequency is not displayed. The table below gives a general overview of the IC-R1's memory channels. BANK INITIAL CONTENTS 40 memories × 20 banks USAGE For normal use. Frequency, mode, tuning step, name and ATT information can be programmed. The number of channels in each bank is user-assignable. Banks cannot be deleted (they must contain at least 1 channel). Frequencies detected during auto memory write scan are memorised into this bank in sequence. Mode and tuning step are written at the same time. Note that when the written memories condition is set as CL&START and auto write scan is started, all memories in this bank are cleared. Undesired signals such as from beacons, control-coded signals, etc. , can be programmed to be skipped during programmed scan and auto memory write scan.
