MorseRunner

An excellent morse-code CW Contest Simulator is a program created by Alex Shovkoplyas (VE3NEA) called MorseRunner.

After you set your own callsign and the speed at which you want to send CW you're set to go. I normally set a duration for 15 minutes and then click on the green Run button to kick it off.

The software is surprisingly good at realistically simulating various types of contacts; some slow, some fast, sometimes fading, with crackles and pops in the background.

Below are a few hints to help me better understand how the program works.

F1 - sends your callsign to initiate making new contacts

Sometimes contacts will prefix their callsign with 'DE', so make sure to listen carefully
