Beginners' Questions Answered</h2>\n\ 760 <div class=\"sectionbody\">\n\ 761 <div class=\"sect2\">\n\ 762 <h3 id=\"_what_is_fldigi\">1.1. What is Fldigi?</h3>\n\ 763 <div class=\"paragraph\"><p><a href=\"http://www.w1hkj.com/Fldigi.html\">Fldigi</a> is a computer program intended for Amateur Radio Digital Modes\n\ 764 operation using a PC (Personal Computer). Fldigi operates (as does most similar\n\ 765 software) in conjunction with a conventional HF SSB radio transceiver, and uses\n\ 766 the PC sound card as the main means of input from the radio, and output to the\n\ 767 radio. These are audio-frequency signals. The software also controls the radio\n\ 768 by means of another connection, typically a serial port.</p></div>\n\ 769 <div class=\"paragraph\"><p>Fldigi is multi-mode, which means that it is able to operate many popular\n\ 770 digital modes without switching programs, so you only have one program to\n\ 771 learn. Fldigi includes all the popular modes, such as DominoEX, MFSK16, PSK31,\n\ 772 and RTTY.</p></div>\n\ 773 <div class=\"paragraph\"><p>Unusually, Fldigi is available for multiple computer operating systems;\n\ 774 FreeBSD™; Linux™, OS X™ and Windows™.</p></div>\n\ 775 </div>\n\ 776 <div class=\"sect2\">\n\ 777 <h3 id=\"_what_is_a_digital_mode\">1.2. What is a Digital Mode?</h3>\n\ 778 <div class=\"paragraph\"><p>Digital Modes are a means of operating Amateur radio from the computer\n\ 779 keyboard. The computer acts as <em>modem</em> (modulator - demodulator), as well as\n\ 780 allowing you to type, and see what the other person types. It also controls the\n\ 781 transmitter, changes modes as required, and provides various convenient features\n\ 782 such as easy tuning of signals and prearranged messages.</p></div>\n\ 783 <div class=\"paragraph\"><p>In this context, we are talking about modes used on the HF (high frequency)\n\ 784 bands, specifically <em>chat</em> modes, those used to have a regular conversation in a\n\ 785 similar way to voice or Morse, where one operator <em>talks</em> for a minute or two,\n\ 786 then another does the same. These chat modes allow multiple operators to take\n\ 787 part in a <em>net</em>.</p></div>\n\ 788 <div class=\"paragraph\"><p>Because of sophisticated digital signal processing which takes place inside the\n\ 789 computer, digital modes can offer performance that cannot be achieved using\n\ 790 voice (and in some cases even Morse), through reduced bandwidth, improved\n\ 791 signal-to-noise performance and reduced transmitter power requirement. Some\n\ 792 modes also offer built-in automatic error correction.</p></div>\n\ 793 <div class=\"paragraph\"><p>Digital Mode operating procedure is not unlike Morse operation, and many of the\n\ 794 same abbreviations are used. Software such as Fldigi makes this very simple as\n\ 795 most of the procedural business is set up for you using the Function Keys at the\n\ 796 top of the keyboard. These are easy to learn.</p></div>\n\ 797 </div>\n\ 798 <div class=\"sect2\">\n\ 799 <h3 id=\"_why_all_the_different_modes\">1.3. Why all the different modes?</h3>\n\ 800 <div class=\"paragraph\"><p>HF propagation is very dependent on the ionosphere, which reflects the signals\n\ 801 back to earth. There are strong interactions between different signals arriving\n\ 802 from different paths. Experience has shown that particular modulation systems,\n\ 803 speeds and bandwidths suit different operating conditions.</p></div>\n\ 804 <div class=\"paragraph\"><p>Other factors such as available band space, operating speed and convenience,\n\ 805 noise level, signal level and available power also affect the choice of\n\ 806 mode. While in many cases several different modes might be suitable, having a\n\ 807 choice adds to the operating pleasure. It is difficult to advise which mode is\n\ 808 best for each particular occasion, and experience plays an important role.\n\ 809 <span class=\"footnote\"><br />[To gain a good insight into each mode and its capabilities, you might\n\ 810 consider purchasing <em>Digital Modes for All Occasions</em> (ISBN 1-872309-82-8) by\n\ 811 Murray Greenman ZL1BPU, published by the RSGB and also available from\n\ 812 FUNKAMATEUR and CQ Communications; or the ARRL’s <em>HF Digital Handbook</em> (ISBN\n\ 813 0-87259-103-4) by Steve Ford, WB8IMY.]<br /></span></p></div>\n\ 814 </div>\n\ 815 <div class=\"sect2\">\n\ 816 <h3 id=\"_how_do_i_recognise_and_tune_in_the_signals\">1.4. How do I recognise and tune in the signals?</h3>\n\ 817 <div class=\"paragraph\"><p>Recognising the different modes comes with experience. It is a matter of\n\ 818 listening to the signal, and observing the appearance of the signal on the\n\ 819 tuning display. You can also practise transmitting with the transceiver\n\ 820 disconnected, listening to the sound of the signals coming from the\n\ 821 computer. There is also (see later paragraph) an automatic tuning option which\n\ 822 can recognise and tune in most modes for you.</p></div>\n\ 823 <div class=\"paragraph\"><p>The software provides a tuning display which shows the radio signals that are\n\ 824 receivable within the transceiver passband. Using a <em>point and click</em> technique\n\ 825 with the mouse, you can click on the centre of a signal to select it, and the\n\ 826 software will tune it in for you. Some modes require more care than others, and\n\ 827 of course you need to have the software set for the correct mode first — not\n\ 828 always so easy!</p></div>\n\ 829 <div class=\"paragraph\"><p>The <a href=\"#ref-rsid\">RSID</a> (automatic mode detection and tuning) feature uses a\n\ 830 special sequence of tones transmitted at the beginning of each transmission to\n\ 831 identify and tune in the signals received. For this feature to work, not only do\n\ 832 you need to enable the feature in the receiver, but in addition the stations you\n\ 833 are wishing to tune in need to have this feature enabled on transmission. Other\n\ 834 programs also offer this RSID feature as an option.</p></div>\n\ 835 </div>\n\ 836 </div>\n\ 837 </div>\n\ 838 <div class=\"sect1\">\n\ 839 <h2 id=\"ref-setting-up\">2.

Watch the waterfall\n\ 1001 display for receiver noise when setting the level. If you see any dark blue\n\ 1002 noise, you have the right input and about the right level. The actual setting\n\ 1003 is not very important, provided you see blue noise. If the audio level is too\n\ 1004 high, the little diamond shaped indicator (bottom right) will show red. The\n\ 1005 waterfall may also show red bands. Performance will be degraded if the level\n\ 1006 is too high.\n\ 1007 </p>\n\ 1008 </li>\n\ 1009 <li>\n\ 1010 <p>\n\ 1011 On Windows, the <em>Record</em> applet can usually be opened by clicking\n\ 1012 <code>Start→Run…</code> and entering <code>sndvol32</code>, or from the Control Panel. If opened\n\ 1013 from the Control Panel, you’ll end up with the Master Volume applet, and need\n\ 1014 to switch using <code>Options→Properties</code>, and selecting the <code>Recording</code> radio\n\ 1015 button.\n\ 1016 </p>\n\ 1017 </li>\n\ 1018 </ul></div>\n\ 1019 </div>\n\ 1020 </div>\n\ 1021 </div>\n\ 1022 <div class=\"sect1\">\n\ 1023 <h2 id=\"ref-guided-tour\">3. Guided Tour</h2>\n\ 1024 <div class=\"sectionbody\">\n\ 1025 <div class=\"paragraph\"><p>The main window consists of three main panes. Study it carefully as you read\n\ 1026 these notes. From top to bottom, these are the Receive pane (navajo white), the\n\ 1027 Transmit pane (light cyan), and the Waterfall pane (black). At the top is the\n\ 1028 collection of entry items which form the Log Data, and at the very top, a\n\ 1029 conventional drop-down Menu system, with entries for File, Op Mode, Configure,\n\ 1030 View and Help.</p></div>\n\ 1031 <div class=\"paragraph\"><p>Between the Transmit and the Waterfall panes is a line of boxes (buttons) which\n\ 1032 represent the Function Keys F1 - F12. This is the Macro group. Below the\n\ 1033 Waterfall pane is another line of boxes (buttons), which provide various control\n\ 1034 features. This is the Controls group. The program and various buttons can mostly\n\ 1035 be operated using the mouse or the keyboard, and users generally find it\n\ 1036 convenient to use the mouse while tuning around, and the keyboard and function\n\ 1037 keys during a QSO.</p></div>\n\ 1038 <div class=\"sect2\">\n\ 1039 <h3 id=\"ref-receive-pane\">3.1. Receive Pane</h3>\n\ 1040 <div class=\"paragraph\"><p>This is where the text from decoded incoming signals is displayed, in black\n\ 1041 text. When you transmit, the transmitted text is also displayed here, but in red,\n\ 1042 so the Receive pane becomes a complete record of the QSO. The information in\n\ 1043 this pane can also be logged to a file.</p></div>\n\ 1044 <div class=\"paragraph\"><p>The line at the bottom of this pane can be dragged up and down with the\n\ 1045 mouse. You might prefer to drag it down a bit to enlarge the Receive pane and\n\ 1046 reduce the size of the Transmit pane.</p></div>\n\ 1047 </div>\n\ 1048 <div class=\"sect2\">\n\ 1049 <h3 id=\"_transmit_pane\">3.2.

The mouse must click in here\n\ 1051 before you type (to obtain <em>focus</em>) otherwise your text will go nowhere. You can\n\ 1052 type in here while you are receiving, and when you start transmitting, the text\n\ 1053 already typed will be sent first. This trick is a cool way to impress others\n\ 1054 with your typing speed! As the text is transmitted, the text colour changes from\n\ 1055 black to red. At the end of the over, all the transmitted text (and any as yet\n\ 1056 not transmitted) will be deleted.</p></div>\n\ 1057 </div>\n\ 1058 <div class=\"sect2\">\n\ 1059 <h3 id=\"_waterfall_pane\">3.3.

Of course, text can always be manually typed or pasted into any of the log\n\ 1260 fields!</p></div>\n\ 1261 <div class=\"paragraph\"><p>You can query online and local (e.g. CD) database systems for data regarding a\n\ 1262 callsign. You make the query by either clicking on the globe button, or\n\ 1263 selecting <em>Look up call</em> from the popup menu. The latter will also move the\n\ 1264 call to the <em>Call</em> field.</p></div>\n\ 1265 <div class=\"paragraph\"><p>When the <em>Call</em> field is filled in, the logbook will be searched for the most\n\ 1266 recent QSO with that station and, if an entry is found, the <em>Name</em>, <em>QTH</em> and\n\ 1267 other fields will be pre-filled. If the logbook dialog is open, that last QSO\n\ 1268 will also be selected for viewing in the logbook.</p></div>\n\ 1269 <div class=\"paragraph\"><p>You open the logbook by selecting from the View menu; <code>View→Logbook</code>.

You can also\n\ 1286 exit the program by clicking on the <code>X</code> in the top right corner of the window,\n\ 1287 in the usual manner.</p></div>\n\ 1288 <div class=\"paragraph\"><div class=\"title\">Op Mode</div><p>This is where you select the operating modem used for transmission and\n\ 1289 reception. Some modes only have one option. Where more are offered, drag the\n\ 1290 mouse down the list and sideways following the arrow to a secondary list, before\n\ 1291 releasing it. When you start the program next time, it will remember the last\n\ 1292 mode you used.</p></div>\n\ 1293 <div class=\"paragraph\"><p>Not all the modes are widely used, so choose a mode which <em>(a)</em> maximises your\n\ 1294 chance of a QSO, and <em>(b)</em> is appropriate for the band, conditions, bandwidth\n\ 1295 requirements and permissions relevant to your operating licence.</p></div>\n\ 1296 <div class=\"paragraph\"><p>At the bottom of the list are two “modes” which aren’t modes at all, and do not\n\ 1297 transmit (see <a href=\"http://www.w1hkj.com/FldigiHelp/index.html\">Online Documentation</a> for details). <em>WWV</em> mode allows you to receive a\n\ 1298 standard time signal so the beeps it transmits can be used for sound card\n\ 1299 calibration. <em>Freq Analysis</em> provides just a waterfall display with a very\n\ 1300 narrow cursor, and a frequency meter which indicates the received frequency in\n\ 1301 Hz to two decimal places. This is useful for on-air frequency measurement.</p></div>\n\ 1302 <div class=\"paragraph\"><div class=\"title\">Configure</div><p>This is where you set up the program to suit your computer, yourself and your\n\ 1303 operating preferences. The operating settings of the program are grouped into\n\ 1304 several categories and there are menu items in which you enter your personal\n\ 1305 information, or define your computer sound card, for example. Modems can be\n\ 1306 individually changed, each having different adjustments. The Modems dialog has\n\ 1307 multiple tabs, so you can edit any one of them. Don’t fool with the settings\n\ 1308 until you know what you are doing! The final item, <code>Save Config</code> allows you to\n\ 1309 save the altered configuration for next time you start the program (otherwise\n\ 1310 changes are temporary).</p></div>\n\ 1311 <div class=\"paragraph\"><div class=\"title\">View</div><p>This menu item allows you to open extra windows. Most will be greyed out, but\n\ 1312 two that are available are the Digiscope, and the PSK Browser. The Digiscope\n\ 1313 provides a mode-specific graphical analysis of the received signal, and can have\n\ 1314 more than one view (left click in the new window to change the view), or maybe\n\ 1315 none at all. The PSK Browser is a rather cool tool that allows you to monitor\n\ 1316 several PSK31 signals all at the same time!
