2022 Helpful Hints


Last Update - 24 Nov 2022


Special Note regarding QSOs with Russia, Belarus and Ukraine

The DX Marathon had previously announced that any QSOs with Russian or Belorussian amateurs would only count in the 2022 DX Marathon if the contacts were made before March 26th, 2022.    With a recent announcement from CQ Magazine, QSOs with those countries will count for DX Marathon credit if made before March 26th or after September 23rd, 2022.   The DX Marathon will accept logs from Russian and Belorussian amateurs for the 2022 DX Marathon but only QSOs made before March 26th or after September 23rd will count.  Russian and Belorussian hams will not be eligible for Plaques or Certificates in the 2022 DX Marathon in accordance with CQ policy.   Amateur Radio activity was suspended by the Ukraine government on February 24th, 2022.   Recently some stations have been active on the air with Ukrainian callsigns – all operating from the Russian occupied areas of Ukraine and not approved by the Ukraine government.   Only QSOs with Ukraine stations made before February 24th, 2022 will count for the 2022 DX Marathon.

  • Each year there are pirates, operations that are not approved, callsigns that are copied incorrectly and unusual operations that are valid.   We attempt to document as many of these operations as possible - see the lists of valid callsigns, invalid callsigns,  and callsign notes.  We encourage you to share your findings on pirates, illegal operations or confusing callsigns with us.  Please send your callsign updates to the DX Marathon administrator at: k9el at dxmarathon.com

  • Many points are lost each year due to bad spots on the packetcluster network.  We have assembled an extensive list of bad spots - please check the list before entering any of these callsigns!

  • Please check USA/VE zones carefully - use www.qrz.com to check zones before submitting.   The number in the callsign does not necessarily match the location.  Did you know that West Virginia (W8) is in Zone 5?  and that Alabama (W4) is in Zone 4?  See US/VE zone detail below.

  • Check Zone 2 submissions carefully - see Zone 2 information below.

  • When a prefix can count for more than country (e.g. E51) double check your entry.

  • Although you can use the same QSO for a country and a Zone, if there is an error, two points will be lost!  We suggest using a different QSO for country and zone.

  • Review your submission carefully and make sure your logging program country database is up to date.
