Live demo — watch the 44-QSO counter climb

From First QSO to Coordinator Email in Four Steps

The entire WWFF activator workflow, automated — no manual ADIF editing, no wrong filenames, no guesswork

  1. 1

    Enter your reference

    Start an activation with your WWFF reference (ESFF-0001, DLFF-0123, VKFF-0001, etc.) — format is validated as you type

  2. 2

    Log contacts from inside the reserve

    Every QSO is auto-tagged with MY_SIG=WWFF and MY_SIG_INFO=your reference. Park-to-park contacts are tagged on both sides automatically.

  3. 3

    Watch the counter climb to 44

    The live counter shows progress toward the 44-QSO valid-activation threshold. Pill turns green with a checkmark once you cross it.

  4. 4

    Export and email

    One click exports your log as CALLSIGN@REFERENCE_YYYYMMDD.adi. Email to your national coordinator — they upload to Logsearch at wwff.co.

ESFF, DLFF, VKFF, KFF — same activation session, same counter, same export. WWFF is a global program and QSL Buddy treats every chapter as a first-class citizen.

68+ National Chapters

Reference Validation

Every chapter's xxFF-NNNN format is validated as you type — no typos, no bad submissions

Live 44-QSO Counter

Amber below threshold, green when you hit 44 — you always know if your activation is valid

Park-to-Park

Working another WWFF activator? Enter their reference — both sides get P2P credit automatically

Reference Format

Every Chapter Uses xxFF-NNNN

WWFF references follow a simple pattern: country prefix + FF + four digits. QSL Buddy validates the format live as you type so you can't accidentally start an activation with a malformed reference.

CALLSIGN@REFERENCE_YYYYMMDD.adi — uppercased, zero-padded, no manual renaming

All required WWFF fields

STATION_CALLSIGN, OPERATOR, CALL, QSO_DATE, TIME_ON, BAND, MODE, MY_SIG=WWFF, MY_SIG_INFO
