VE2EMM graciously offers to program your PICs for this project. The processor sends DE in slow CW, then waits for the new callsign to be entered. Repeat previous step for the remaining characters of the callsign. The unit sends each character in CW when S2 is pressed, for verification. Replace jumper JP1 and press S3.
Operation resumes with new callsign.
When Jumper JP1 is in place, the setting of the nine-section dipswitch selects startup delay, fox message and cycle rate. This feature is used in European hunts to signal the end of a practice session. It also prevents complete discharge of the fox batteries if the box isn't recovered immediately.
