Radio Amateurs please note: the following Q-codes are endangered, due to underuse. This page is the home of the Campaign to Protect Endangered Q-codes. The object of the campaign is to rescue these Q-codes from extinction, by making use of them as often as possible. Take action now - memorise these codes, and try to include them whenever possible in all forms of communication.
