QSL Amateur Radio

In amateur radio a QSL is a written comfirmation of a two-way contact through radiocommunication.

In old times confirmation happened by sending QSL cards (similar to postcards). One station would send a QSL card and hope that the other station too would send written confirmation of the contact.

Today, systems are based on digital QSL cards and digitally signed QSL. If the data from both stations match, then they form the proof that the two-way radio contact happened.

This collection is the next innovation, where two-way radio contacts are confirmed through the block chain as non-fungible tokens (NFT). They remain as digital collectibles long after the QSO, in the same spirit that QSL cards did before.
