A silent key is a deceased amateur radio operator. The “key” is a reference to the
telegraph keys historically used to transmit information, and although it is now
largely obsolete, its status is so iconic that most people in the amateur radio
community understand the reference. SK sent in Morse Code signals “end of
transmission” so it is only fitting that deceased operators be identified this way to signal their passing.
This page is dedicated to the Silent Keys of the Middle Peninsula Amateur Radio Club. If you know of a past member that is not included, please notify us so that we may add them to this list.
