All I can figure is that Hornady is using a different frequency than what is industry standard.
Some additional info, My Diagnostic card works. I double checked it with my phone afterwards. I couldn’t for the life of me get a hold of Hornady to get my question answered. Even after filling out their ridiculous requirements to send them an email (They wanted my home address, phone number, etc. None of which I gave them).
Also, it seems I’m not the only person to have this problem with this company recently.
