Arlen, AA0SG, wrote this wonderful Morse Code generator for the HP48 series of graphing calculators. It is based on the Farnsorth method with three general speeds and configurable audio frequency.
- Download and transfer the program to you HP48 calculator. This will create a directory call MORSE.
- In that directory, pressing the CST key will bring up the custom menu.
- The MESS vafiable stores the string to be sent. Enter a string on the stack and left shift the MESS variable key to store it. Right shifting the MESS key recalls the message. Only uppercase letters are valid.
- Press the RUN key to play it back.
- Entering a number and pressing the HZ on the custom menu sets the audio frequency (in Hertz).
- SLOW, MED, and FAST set the speed.
- AR, SK, comma, and question mark insert the approriate characters tnto the string.
