& School Club Roundup Links


SCR is a wonderful weeklong Amateur Radio event held each February and October. Even if you are not a school, here is a great opportunity to encourage young people and leave them with a favorable impression of Amateur Radio. SCR-Log is freeware for School, Club, and Individual class stations participating in the School Club Roundup.

I keep the SCR-Log application folder on my desktop during SCR week for easy access. Delete the folder and contents to "uninstall" the program. ADIF export is provided to feed your regular logging program.

On the other hand, if you make only a few SCR contacts, SCR-Log is a convenient way to log them at the end of the week and create a Cabrillo report. First set the date/time option to manual entry to bypass automatic date/time stamping.

Version 6.5 for Mac and Windows was released on September 4, 2017.

SCR Cabrillo Specification
There was a new Cabrillo specification for the October 2015 School Club Roundup which reflects a change in how modes are reported. "CW" is now used for Morse code contacts only. The new mode designation "RY" is to be used for all other digital contacts.
