In this exercise, you will receive a simulated digital transmission with fldigi that is formatted for display in flmsg.
There should also be an alert if the message was not received perfectly. It would clearly be better for the incoming message to be saved and opened with an application designed for display and printing. Second, what if there had been a burst of static during transmission that corrupted some of the information? Are you sure that all the names of these medications came through accurately? Third and worst of all, what if the operator at the receiving station is distracted, or away from the desk, and does not notice that the message has even been received? The message has scrolled upward in the receive panel and is out of sight. You can do that with this example go ahead and try it. The best that can be done is to scroll back in the receive panel, select the message content, and paste it into a text editor or word processor. First, this message will almost certainly need to be printed by the receiving radio station, by fldigi does not provide an easy way to do that.
Though you may have been thinking that this message took a very long time to send and receive, imagine how long it would have taken, and how many errors are likely to have happened, if the message had been sent by voice! If you were paying attention, you saw that this was a message requesting a long and very detailed list of needed prescription medications for disaster evacuees. Un-check the box at "File|Audio|Playback" to stop playback, or allow it to continue playing to the end of the file. The specified file will then begin playing. You will probably want to answer the question "playback continuous loop?" with "No". Locate and select the first file to be played, D2.2.1.wav, in your workspace folder and press the Open button. Use "File|Audio|Playback" and check the checkbox. (Using this link will open the page in a separate browser window or tab.) In this exercise, you will receive a simulated digital transmission with fldigi that is not formatted for display in flmsg.Ä®xercise configuration: Before beginning this exercise, follow the steps outlined on the Off-the-air exercise preparation page. FilesÄownload these files, one by one, and save each of them to your workspace folder: You will be receiving simulated transmissions using the Audio Playback technique that you learned in Step 1.2 of this course. These files will arrive in fldigi as digital transmissions and be recognized as files intended for display by flmsg. In Step 2.2 of this course, you will get experience receiving digital files with flmsg. next page Step 2.2: Receiving an flmsg message.
