User manual ICOM IC-PCR100

[. . . ] INSTRUCTION MANUAL COMMUNICATIONS RECEIVER FOR COMPUTER iPCR100 This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. IMPORTANT READ ALL INSTRUCTIONS carefully and completely before using the receiver. OPERATING THEORY Electromagnetic radiation which has frequencies of 20, 000 Hz (20 kHz*) and above is called radio frequency (RF) energy because it is useful in radio transmissions. The IC-PCR100 receives RF energy from 0. 5 MHz* to 1300 MHz and converts it into audio frequency (AF) energy which in turn actuates a loudspeaker to create sound waves. AF energy is in the range of 20 to 20, 000 Hz. * kHz is an abbreviation of kilohertz or 1000 hertz, MHz is abbreviation of megahertz or 1, 000, 000 hertz, where hertz is a unit of frequency. SAVE THIS INSTRUCTION MANUAL -- This instruction manual contains important operating instructions for the IC-PCR100 COMMUNICATIONS RECEIVER FOR COMPUTER. [. . . ] · When inputting a frequency outside of the allowed receive frequency range, the previously selected frequency is automatically selected after clicking [Enter]. D Using the simple function receiver screen q Click [MENU] and select the `Function Controller' when it is not displayed. w Click [FREQ J] or [FREQ K] on the function controller to set the frequency according to the selected tuning step. · The frequency changes according to the selected tuning steps. · When clicking and holding either button the frequency scrolls up or down. 17 3 BASIC OPERATION s Setting a tuning step When using the tuning dial or [FREQ J]/[FREQ K] buttons to change the frequency, or when a scan function is activated, the frequency changes in increments determined by the set tuning step. · 1 kHz · 5 kHz · 6. 25 kHz · 9 kHz · 10 kHz · 15 kHz · 20 kHz · 25 kHz · 30 kHz · 50 kHz · 500 kHz · 1 MHz · 10 MHz s Receive mode selection Receive modes are determined by the physical properties of the radio signals. Typically, AM mode is used for the AM broadcast stations (0. 495­1. 620 MHz) and air band (118­135. 995 MHz), and WFM is used for FM broadcast stations (76­107. 9 MHz). When using the automatic mode function, a receive mode, tuning step and filter selection are automatically selected after inputting a frequency. · 12. 5 kHz · 100 kHz D Using the multi-function receiver screen Click [TS J] or [TS K] to set the desired tuning step. · The selected tuning step is displayed in the function display. D Using the multi-function receiver screen Click [FM], [WFM], [AM] or [AUT-M] to select the desired receive mode. D Using the simple function receiver screen q Click [MENU] and select the `Function Controller' when it is not displayed. w Click [TS J] or [TS K] on the function controller screen to select the desired tuning step. · The selected tuning step is displayed in the information display if the information display is in use. D Using the simple function receiver screen q Click [MENU] and select the `Function Controller' when it is not displayed. w Click [AM], [FM], [WFM] or [AUT-M] to select the desired receive mode. 18 BASIC OPERATION 3 s Automatic mode selection An automatic mode function is available to automatically set the receive mode, IF filter passband width and tuning step after inputting a frequency. Each click of the [AUT-M] button toggles the automatic mode function on and off. · For the simple function receiver screen, the [AUT-M] button is on the function controller screen. w Click the [Auto Mode] tab to display the automatic mode list. D Setting the automatic mode function The default setting for the automatic mode function can be added to, changed or deleted. Up to 20 ranges can be memorized into the automatic mode function settings. q For the multi-function receiver screen, click the [SET] button to call up the setting screen. For the simple function receiver screen, click the [MENU] button and select the `Function Setting (SET)' to call up the setting screen. r Input the lower frequency of the frequency range from the keyboard, then push [Enter]. · When nothing is input into the [Freq Low] or [Freq High] column, settings for other columns cannot be made. · When inputting a new frequency, other data automatically appears in the other column. · To delete a frequency range setting, enter [0] or [Space] into the [Freq Low] column from the keyboard. t Input the higher frequency of the frequency range into the [Freq High] column, push the [Enter] key. y Set other data such as mode, tuning step, etc. , if desired. Click to bring up the setting screen. · Double-click the desired cell, select the desired item and doubleclick the selection. u Click the close (["]) button to close the setting screen. 19 3 BASIC OPERATION s Setting squelch level The squelch function sets a minimum receive signal level below which no audio is emitted from the speaker. This conveniently prevents noise and static from being emitted when receiving weak signals or no signals at all. The squelch does not open if a signal below the set S-meter level is received. s IF filter selection Increasing or decreasing the width of incoming signals can help eliminate interference. See the table below. IF filter FM WFM AM 6 kHz K ­ K 15 kHz K ­ K 50 kHz K K K 230 kHz ­ K ­ K: Factory setting; K: Selectable; ­: Not selectable D Using the multi-function receiver screen Click the [SQUELCH] control with the sub mouse button to increase the squelch level (tight squelch); click the [SQUELCH] control with the main mouse button to decrease the squelch level (loose squelch). · The S-meter squelch level is displayed in the function display. D Using the multi-function receiver screen Click the [WID] or [NAR] buttons to toggle between filter widths. D Using the simple function receiver screen q Click [MENU] and select the `Function controller' when it is not displayed. w Click [WID] or [NAR] on the function controller to select the filter width.
