    If other expansion cards are fitted, check their address assignments. If necessary, change any of the jumpers on the WiNRADiO receiver card to avoid conflicts. (The default I/O port 180, IRQ 10 and DMA 0 should normally work, however if you need to change any jumpers, see the following section about ‘Jumper Settings’.)

    3, 5, 7, 9, 10, 11, 12 and 15, and 2 DMA channels: 0 and 3. The factory default is I/O port 180, IRQ 12 and DMA 0. If more than one WiNRADiO card is to be installed in the computer (up to 8 depending on available address lines), each card must be assigned a unique I/O address and IRQ. The DMA channels can be shared, all eight are able to run on one DMA channel, but it is recommended to evenly distribute the card’s DMA settings across the two channels if...

    Start up the computer and try auto-detecting again. If you are using an external WiNRADiO model, make sure it is plugged in and the power is turned on (the red LED on the front panel should be illuminated).
  • Page 8 WR-3700 Series User’s Guide Intermodulation Problems Your WiNRADiO receiver has been designed to be very sensitive in order for it to work with the moderately small antennas which are preferable for VHF/UHF. In areas with strong local broadcast stations, the WiNRADiO receiver front-end may overload and, as a result, intermodulation products may appear in the received band.

  • Page 9: Basic Controls

    WR-3700 Series User’s Guide Using WiNRADiO When you first start WiNRADiO, you are presented with a radio receiver interface. The image below shows the main parts of the control panel. The following few sections document each of the parts in detail.

  • Page 10: Signal Level Meter

    To reduce the step size to 1 Hz for more accurate tuning of LSB, USB or CW, use the Alt key simultaneously with the mouse or keyboard tuning commands. Modes WiNRADiO WR-3700 series supports eight different reception modes (CW, LSB, USB, AM, FMN, FMN2, FMN3 and FMW). These modes are abbreviations of Continuous Wave (CW), Lower Side Band (LSB), Upper Side Band (USB), Amplitude Modulation (AM), Frequency Modulation Narrow-band (FN) and FM Wide-band (FW).
  • Page 11 WR-3700 Series User’s Guide If you wish, you can have different squelch thresholds for normal reception and scanning. To activate this feature, go to Configure - General Options and select Separate squelch for scanning. The receiver will then accept different squelch thresholds on the front panel, and in the ‘Scanner - Setup’...

  • Page 12: Memory Stepping

    Memory WiNRADiO has the ability to store up to 1000 frequencies in a memory file, and the total number of memory files is limited only by hard disk capacity. Each entry is assigned the following: a number from 0 to 999, the frequency, mode, group number(s), callsign and comment.

  • Page 13: Storing A Frequency Into Memory

    Storing a Frequency into Memory To store the current frequency you are tuned to into one of the 1000 memory locations in WiNRADiO, you can either click on the S button in the Memory panel, or press S on the keyboard.

  • Page 14: Control-Number

    When you start your WiNRADiO receiver for the first time, it creates a memory file called winradio.wrm. Every time you close your WiNRADiO session, the memory is automatically saved to the active file.

  • Page 15: Frequency Range Scanning

    WR-3700 Series User’s Guide Scanning WiNRADiO provides a variety of scanning functions and options, to allow you to optimise the way you search for stations. The scanner steps through frequencies until it finds a transmission that has a signal strength greater than the squelch value.

  • Page 16: Scanner Options

    WR-3700 Series User’s Guide Select the range of memory numbers to scan, mode and group restrictions. Click on the Scan button to start scanning, or click on the Close button to exit the dialog box (your settings will be remembered).
  • Page 17 Miscellaneous Mute The Mute button controls the audio output of your WiNRADiO receiver. If it is on, the output is muted (switched off). To activate (or deactivate) the mute control, click on it or press Ctrl+U.

  • Page 18: Power Switch

    WR-3700 Series User’s Guide The ‘PLL’ indicator shows the lock status of the receiver’s Phase Lock Loop. When operating normally, the indicator is green. If something goes wrong, it will turn red indicating that the receiver cannot tune into a specific frequency.

  • Page 19: Background Colour

    To move the window around the screen, click-and-drag on any inactive part of the WiNRADiO panel or background. To show the title bar and menu, select the Hide title bar command in the View menu.

  • Page 20: Spectrum Scope

    WR-3700 Series User’s Guide Spectrum Scope The ‘Spectrum Scope’ is a utility to display and store the signal level across a frequency range. After a frequency sweep has been performed, you can tune to any frequency on the display. To tune to a frequency or peak on the display, click on it. You can hold down the mouse button and drag the cursor across the display quickly tuning to any frequency on the display (this facility will be described in greater detail under chapter heading ‘VisiTune’).

  • Page 21: Saving And Loading Files

    If you double-click at a point on the display, WiNRADiO will search for the highest peak nearest the cursor depending on the slope of the sweep at the cursor. It will check the level at either side of the frequency where you double-clicked.
  • Page 22 Select the appropriate method in the dialog box. You can set up WiNRADiO to mute the audio or not when it starts a sweep. It will mute the audio if Mute while sweeping is checked.

  • Page 23: Task Scheduler

    WiNRADiO includes an advanced task scheduler that can be configured to schedule almost any task that WiNRADiO can perform. Each task can be triggered by a selected combination of date and time, signal level rise or fall and DSP event. Each task can activate any number of times and time-triggered tasks can occur at discrete intervals.
  • Page 24 Used on its own (or with the DSP event), this task can trigger at any time while WiNRADiO is operating. If you would like it to trigger after a certain time, specify a date and time trigger event.
  • Page 25 WR-3700 Series User’s Guide The file name can also include a #d, #t, #f and/or #n to specify the date, time, frequency and a unique number respectively. If you need a # in the file name, enter ## (double-hash). The date and time will be represented as a 6 digit number and the frequency is in kHz.

  • Page 26: Sound Recorder

    WR-3700 Series User’s Guide Sound Recorder The inbuilt DSP allows WiNRADiO to record and playback audio files without the need for a separate sound card. The file generated is a standard Windows .WAV file which can be played by any third party software application.
  • Page 27 Logger The WiNRADiO Logging facility can store the date, time, frequency, mode, level and a comment. When a log entry is added from WiNRADiO, the current date, time, frequency, mode and signal level is appended to the log.
  • Page 28 The editor allows you to open multiple files at the same time, cut, copy and paste between them. You can modify and print the contents, search and sort and tune WiNRADiO to any entry. You can even copy a range of entries to the clipboard and paste them into another program such as Microsoft's Excel or Corel's Quattro Pro.
  • Page 29 Selecting a Log File WiNRADiO can add log entries to any log file. To choose the log file to add entries to, select Log file from the Logger menu. Either choose an existing log file or enter a name for...
  • Page 30 WiNRADiO can automatically switch between antennas according to the frequency WiNRADiO is tuned to. If this feature is used, the entire frequency range of WiNRADiO (150 kHz to 1.5 GHz) should be covered. Otherwise, if you tune to an unspecified range, the reception can be very poor due to the wrong antenna being selected.
  • Page 31 To add a new applet, copy the file into the directory where WiNRADiO is installed. Applet files have a .DSP extension. If WiNRADiO is already running, close it down first. When WiNRADiO starts up, it will load all the DSP applets found in its directory and add the applet's functions to the DSP menu.
  • Page 32 WR-3700 Series User’s Guide Gain sets the pre-processing numerical gain of the signal inside the DSP. This parameter helps to resolve the ‘signal-to-noise vs. audio distortion’ trade-off. If the filtered signal sounds too distorted, choose a lower gain. The ‘AGC’ option activates automatic gain control algorithm.
