Dealing with a Broken Callsign Certificate

If the private key associated with a Callsign Certificate goes missing or is damaged, TQSL's Callsign Certificates tab will display that Callsign Certicate with a broken icon: . To correct this, either

• restore the Callsign Certificate and its private key from a backup file

or

• restore the Callsign Certificate and its private key from a previously-saved certificate container file

or

• delete the broken Callsign Certificate and request a replacement.
