Club Calls

Clubs must create an UNSIGNED certificate request for the primary club call.  This primary call will receive its own LoTW login and password.  Certificates for additional calls for the same club must have a SIGNED certificate using the primary club call certificate to sign the request.

If you are no longer able to be the trustee for a club call then the account can be transferred to another person’s control.

Calls with Portable Identifiers

Certificates for calls with portable identifiers (W1AW/4) should be SIGNED using your primary call certificate and have a date range that corresponds with the portable operation.
