Now in its second year, Bunkerfest is a WWBOTA-sponsored weekend of bunker activation and hunting backed by national societies.

• Promote the Worldwide Bunkers on the Air scheme
• Encourage bunker activations across every WWBOTA member country
• Encourage worldwide bunker hunting and shortwave listening
• Have fun activating and chasing

1. HF activators require a minimum of 25 QSOs to activate a bunker. Return visits within the 72 hours are permitted to reach the total.

2. VHF activators require a minimum of 10 QSOs, with the same return-visit allowance.

3. All simplex modes may be used — voice, CW, and data including FT modes. Repeaters, internet gateways and VOIP services (e.g. Peanut) are not permitted.

4. A station may only be worked once at each bunker; additional modes or bands don't score as an extra QSO. A hunter may only claim a bunker once, even if a different activator is worked there later.

5. One bunker per activation. Where an activation zone covers several bunkers (a "3-fer"), only one may be claimed per visit — the others may be activated separately, each requiring its own minimum QSO count. A bunker may be activated once on HF or once on VHF, not both.

6. Activators must leave a minimum 10-minute gap before switching bunkers, or QSOs risk rejection by the logging system.
