The Internet uses the same basic technology, and probably the same wires, too, in some places, so it's appropriate that we should take a look at software for sending and receiving Morse code via a PC. Known by the shorthand CW, Morse code is a direct ancestor of computer code. Most people know what Morse code is, too: Named for its inventor, it's the dots and dashes that the telegraph man so dramatically taps out on a metal key in old Western movies.

If you said the telegraph, you're right. Peter DeNeef, AE7PD, is an Extra Class amateur radio operator in the U.S.

No special interface hardware is required.ДЄ separate article describes how to configure CwGet. It can also be used with a magnification program. SummaryД¬wGet is a Morse decoder with a range of built-in options for displaying received text using high-visibility fonts and colors.

Movement of the vertical red tuning line on the spectrogram indicates that AFC is on. The effect is subtle, and it may be easier to use the second red line on the oscillogram as an indicator that Auto-Threshold is on. The image of each button appears slightly raised (off) or depressed (on). The buttons in the control bar above the oscillogram are controlled with mouse clicks. Red line shows the noise level used to set the threshold. (2) With Auto-Threshold on, the program sets the level andД¬hanges it when the signal strength varies. (1) With Auto-Threshold off, click on the signal at the chosen level. Using the oscillogram, you can decide whether the signal-to-noise ratio is high enough for accurate decoding. When the signal exceeds this voltage, the program registers a code element-a dot or dash. The horizontal red line is the detection threshold. The bottom pane in each figure is an oscillogram of the received signal. The procedure for using it is described in the article on configuring CwGet. The small black vertical line in the spectrogram is a movable marker that is useful when tuning a transmitter.

When AFC is on, this line tracks the signal if it drifts, and a small red line stays at the original frequency. A vertical red line marks the frequency of the CwGet audio filter. The top pane in each figure shows the spectrum of received signals. For larger text you can use a larger screen or magnification software.ДЇigure 1. On a typical display set for 120 dpi the letter height is 0.3 inch. Program DescriptionДЇigures 1 and 2 are screen captures from a CwGet window with the decoded text in 24 point bold type.

Your own skill is essential when the signal to noise ratio is too low for a decoder.Дecoded text is also useful when you practice receiving CW. Some eHam reviewers suggest using the program as an aid to your own copying-to check an occasional word or to record the exchange information in a contest. With decoders, poorly timed code or a noisy signal can cause

CwGet does not decode every signal you can copy.

The two programs have some similiar controls and menus, including a wide range of options for fonts and colors. You can use a single cable to connect the speaker output from a receiver to a computer with a sound card.Д¬wGet was written by Sergei Podstrigailo, UA9OSV, the author of TrueTTY for digital modes.
