- The first thing you should do when you run CW is to calibrate the code speed
- to suit the clock speed for your computer and to account for any memory
- resident programs which you have loaded. Each time you change the memory
- resident program enviroment you will need to recalibrate code speed. When
- doing so use the following procedure:
-
- 1. Select the <U>tilites command from the main menu.
-
- 2. Select the <A>uto Calibrate subcommand. This will automatically
- provide an approximate calibration. For best results continue with the
- following steps.
-
- 3. Select the <S>peed test subcommand.
-
- 4. Using a clock or watch with a sweep second hand, count the number
- of times the standard word PARIS is sent in exactly one minute. Since the
- calibration is done at 20 words per minute, you should count exactly 20
- words sent in one minute if the calibration is correct. If exactly 20 words
- are counted, then no further calibrations necessay.
-
- 5. If the number of words and code speed do not match, then use the
- <U>tilities command and <T>iming subcommand to set the timing constant.
- Increasing the number slows the send speed down, and vice versa.
-
- 6. Repeat steps 1-4 until the code speed shown at the bottom of the
- screen matches the number of words sent in one minute.
-
- In counting the number of times PARIS is send, be sure to include the
- last word space as part of the last PARIS. In other words, if you are
- attempting to calibrate at 20 words per minute, start timing when the first
- word is sent and stop timing when the 21st word starts.
-
- On my Zenith Z-150 running at 4.77 MHz. and with no memory resident
- programs installed, the timing factor is about 1175. With several memory
- resident programs installed, the timing factor decreased to considerably less
- than that (in the 600 range). For users of versions previous to 4.01, the
- factor has increased about 100 in this version to the above figure, apparently
- due to the greater efficiency of the Turbo Pascal 4.0 compiler.
