How do I report a Silent key?

The best way is two-fold:

1. Post in the sub-forum linked here, with his name and call sign in the title and if you have it, the obituary in the body of the post. If you don't have an obituary, at least tell folks about the person even if just in a sentence or two: https://forums.qrz.com/index.php?forums/silent-keys-friends-remembered.18/

2. Then file a Support ticket, and choose the "Silent Key" option as the reason - and just tell Support who passed: https://ssl.qrz.com/support The Support team will then flag his QRZ Bio page as SK for Silent Key.

That's "best practice"
