Today's #hamRadioBreadth looks at ways to prove a QSO happened.
Old-fashioned paper QSL cards can be pretty - and a royal PITA to produce, ship, process.
Today's internet has online services that verify QSOs: Some by national clubs like ARRL or DARC, several offered commercially. Alas, those don't talk to each other. If the sets of services two hams use do not intersect, .
This needs improvement.
I want a public/private key pair for each ham and signed QSL records accepted by all services.
