Welcome to UK Bunkers on the Air (UKBOTA)

What is UKBOTA?

The aim and purpose of the United Kingdom Bunkers On The Air (UKBOTA) programme and awards scheme is to support radio amateurs and short-wave listeners, both in the United Kingdom and overseas, to communicate with other radio amateurs activating ROC and other types of bunkers in the United Kingdom. UKBOTA is proud to be part of Worldwide Bunkers on the Air (WWBOTA). More information on WWBOTA and with links to other national partner schemes can be found hereWhilst not a contest, awards (PDF certificates) will be issued to both activators and hunters submitting logs and demonstrating QSO with the requisite number of stations. Awards are also available for SWL submitting reception logs. UKBOTA is beginner friendly but also offers challenges to the more experienced portable operator and activation chaser. UKBOTA is not a competitve awards scheme, we make a point of not producing league tables.
