HF Scoring

2 points for each bunker activated (25 QSO for a valid activation) from the list of valid airfield bunkers. 

HF Bonuses

For valid activations:

1 additional point per 50 QSO, up to a maximum of 3 additional points.
1 additional point for 5 or more UKBOTA valid airfield bunker to valid airfield bunker (B2B) QSO

The highest possible HF score for each bunker is, therefore, 6 points. 

Total HF points available for each bunker, with including bonuses:

25-49 QSO = 2 points
50-99 QSO = 3 points
100-149 QSO = 4 points
150+ QSO = 5 points
(with 5 UKBOTA Airfield B2B QSO) = 6 points

HF Information

Activators may return to a bunker within the month in order to gain more QSO (the maximum scoring HF QSO is 150 for each bunker). The same station may be worked for additional QSO, but only on different days.

There are no additional scoring QSO for working the same station on a different band, or mode, on the same day.

For this event multiple bunkers may not be worked in the same activation. Where a cluster of overlapping bunker activations exist (eg. a 3 fer) then each bunker must be activated as a separate activation. There must be a minimum of 10 minutes gap between each activation.

Additional Note:

If an activator is not participating in AFB25, and is activating a location with multiple Airfield bunker references, then the hunter may only claim one bunker for AFB25. We recommend that hunters log the first bunker reference provided by the activator for their AFB25 Hunter Award.

Additional bunkers will not count for AFB25 unless:

• The activator takes a 10-minute break before starting the next activation, and
• The previous bunker is no longer being activated when the new activation begins.
