I have an old callsign or two, and I would like to enter logs for those calls into LoTW also. How do I do that?

This is one of the most common questions fielded by the LoTW staff. The first concept to remember is that each and every different callsign must have its own certificate. Every LoTW participant should obtain a certificate for his/her primary callsign -- that is, for the callsign that is presently being used in the place where the applicant lives most of the time. Do not request certificates for additional callsigns until you have received your certificate for your primary callsign. Once you have received that first certificate for your primary call, you can then request additional certificates for your other calls. You should use the primary certificate to sign each additional request. The TQSLCert program will prompt you to sign those requests and it is strongly recommended that you do so. Signing the requests allows the LoTW website to easily group together all of the QSOs made under your various callsigns for your viewing pleasure.

LoTW checks the FCC database for existing callsigns for U.S. applicants, so that is why you cannot initially request a certificate for your old callsign, which probably isn't in the database (or your old call has been reissued to someone else, and the data won't match for your name or address).

Stations outside the U.S. also should begin by asking for a certificate for primary callsigns. After the first certificate for the present callsign is received, then each subsequent request for certificates for old calls should be signed with the present/primary callsign's certificate. LoTW will then be able to keep all the data from old callsigns together with the present callsign's logs in an orderly fashion.
