Instructions for ESFF activity


ESFF as a Hunter

  1. Register to and fill your profile (registration is confirmed manually, so it may take a few days).
  2. has lots of information about WWFF-programme, operation agenda, WWFF DX-cluster and WWFF-reference directory.
  3. Work WWFF-stations! The popular Flora&Fauna frequencies are:
    Phone: 3.744, 7.144, 14.244, 18.144, 21.244, 24.944, 28.444

  4. Your QSL-card is not needed for WWFF-awards! What is needed is that WWFF-station who worked you, will send his/her log to WWFF-manager (in Estonia to ES1NOA). You can manage your awards via “Logsearch” on
  5. Apply global and national WWFF-awards via Logsearch-page. Awards hosted at WWFF-site are free and are sent by email (JPG or PDF).
  6. Logsearch -> Top operators page lists top hunters and top activators. Number #1 hunter has over 13000 WWFF-references worked!

ESFF as an Activator

  1. Check ESFF directory at: and choose the reference to activate. Directory also shows how many accepted qso-s from that reference has ever been worked.
  2. Choose your QTH carefully. The whole station: radio + antennas must be located inside the reference area. The blue question mark on directory page opens map for this reference.
  3. Additional information about references and their borders can be found from:
    1. (by ES1NOA - ESFF-references on the map)
    2. (by ES1NOA - ESFF-references with additional information on Google spreadsheet)
    3. Natura 2000 areas on the map
    4. X-GIS 2.0 [looduskaitse] ( Estonian Nature conservation and Natura 2000 sites (Looduskaitse ja Natura 2000 alad)
  4. Make an operation! Minimum of 44 qsos is needed to “qualify” the operation for the top operators’ list, but you can collect 44 qsos on separate occasions. Even if you work less qsos, send your log, as it is good for hunters! For hunters there is no minimum requirement.
  5. Name format for your log is like ES1NOA @ ESFF-0001_20190101 (call @ ref# date).
  6. Any log programme which has ADIF-format (.adi/.adif) is good, but your log needs the following fields:
    Callsign used: STATION_CALLSIGN
    Operator callsign: OPERATOR
    Hunter’s callsign: CALL
    Date: QSO_DATE
    Time: TIME_ON
    Band: BAND
    Mode: MODE
    MY_SIG is “WWFF
    MY_SIG_INFO is your ESFF-reference like ESFF-0001SIG is “WWFF”

    If you have qsos to other WWFF-references (so called “park to park qsos”) you need also:

    SIG is “WWFF”
    SIG_INFO WWFF-reference number of worked WWFF-station like OHFF-0123
  7. If you use paper log, the recommended software to convert it to ADIF is DF3CB’s Fast Log Entry (FLE) which is free and an easy text editor to produce ADIF-files for WWFF. You can use FLE in real-time or off-line.
  8. Submit ADIF-log to ESFF manager to: . If you visit several times the same reference area, send your log after each operation. QSLs are not needed for WWFF awards.
  9. Send also documents to prove from where you operated. Take e.g. a snapshot of your smart phone’s map programme or photo from your GPS position or send another document proving your location. You can also send photos of your WWFF-setup and nature area border signs.
  10. ESFF manager will inform you when your log has been accepted and uploaded to
  11. Logsearch -> Top operators page lists top hunters and top activators. Number #1 activator has over 1200 WWFF-references activated! 

    Good luck!
