The Radio Society of Great Britain (RSGB) has an online QSL Card generator for the Coronation. The Link is here: https://thersgb.org/services/qsl-coronation/ . The only problem is the IOTA registration number - it is for the Island of Great Britain only. For example the Outer Hebridies are EU-010 - so they are excluded as is Jersey (EU-013) etc. We recommend one edit the IOTA reference or just delete it altogether.
