In radio communication, what should be specified regarding alpha/numeric characters?

In radio communication, it is essential to specify alpha characters occurring in a series to ensure clarity and accuracy in conveying information. This is particularly important in law enforcement settings where miscommunication can have serious consequences. When alpha characters are used sequentially, there may be a risk of confusion with similar-sounding letters or numbers, especially under stress or in noisy environments. By specifying the alpha characters in a series, the receiving party can better understand the message and avoid potential misunderstandings.

Additionally, while it may seem less relevant to focus solely on numeric characters or to discuss shapes and colors, these factors do not directly address the critical need for clarity in communication. The emphasis on alpha characters occurring in a series is rooted in the necessity of maintaining effective and unambiguous communication between personnel in the field.
