Minimum distance for WRL DX? [IN DISCUSSION]

App Help & How-To
1

Perhaps a basic question, but at what distance does WRL consider a QSO to be Dx for purposes of the Leaderboard and the Spotting filter?

@KF0EEK Hey Jack,

So DX is based on country so it goes based on your location. example: if your in the US anywhere outside of the US is considered DX. Hope this helps.

Thanks & 73

Thanks. I got a little confused because I have “United States” and “United States of America” in the DX box on my logbook Stats page.

Hi Brad @K4AZE

Your definition of “DX” may be true in North America, which has two very large countries. But for Africa, Southeast Asia or Europe, your definition of “DX” is not accurate nor accepted by the Hams living there.

Remember: In Europe, countries are roughly the same size as a single state in the US or a single province in Canada.

Here, too, the World Radio League needs solutions working worldwide. :wink:

One definition I am familiar with is

  • more than 3000 km is DX for HF. (approximately 2000 miles)
  • more than 300 km is DX for VHF. (approximately 200 miles)

But there are also other definitions, such as

  • DX = connection between two continents. (However, this definition is not suitable for Asia* and Africa**)

  • = The distance between Ankara (Turkey) and Seoul (South Korea) is approximately 7,750 kilometers (4,800 miles).
    ** = The distance between Cairo (Egypt) and Cape Town (South Africa) is approximately 7,300 km (4,500 miles)

Perhaps DX could be based on operator’s location. Outside of continental US if in continental US, a certain distance if based elsewhere.

Hey Pepe,

This is very good information! Thank you! I’ll talk to the team during our meeting tomorrow and pass this along and get this added as a mini feature.

Thanks & 73

No, Sir! USA is not that special that we need two definitions, one for USA and one for the rest of the world. :wink:

We are searching a solution which fits wordwide for all large countries (like Australia, Brasilia, Canada, China, India, Russia, USA, …) and for all small countries.

A possible definition for DX could be: The signal distance for HF is at least 3,000 km (2,000 miles) and must cross at least one national border.

There is no “worldwide” accepted definition. “Dx” is not standardized in the amateur radio world. You can find discussions similar to this on every forum.

It’s not a matter of USA being “special.” The commonly used definition in the US is a contact out of the country. Europeans may use other standards. My suggestion was a way to allow both, but is likely a cumbersome and untenable solution.

The ARRL recognizes “definable political or geographic distinctiveness,” which is what WRL currently uses. Your “3km/2k miles” is just another arbitrary definition.

I think we should keep it as it is. It works and it is commonly used by many radio operators.

Hi Jack @KF0EEK
I do absolutely agree with you: there is no worldwide accepted definition what "DX is. So it’s up to WRL team to make there own definitions for the WRL plattform.

For the US there is already a clear definition made:

I am asking me, if other large countries are handling it equally to US?

So I am asking Andy @VK2VOO and Haydon @VK4NU :
How is “DX” defined typically in in Australia?

And asking Earnest @VA3EWV, John @VE3IPS, Steve @VE3MMH and Stuart @VE9CF
How is “DX” defined typically in Canada?

US in NOT DX for Canadians

As a DX Hunter I typically will never work a US station calling CQ DX and I call CQ DX I typically call on the US Extra portion of the band on SSB or even outside of US phone privileges so I can hear the DX stations.

Sorry, but that is me…

US stations don’t interest me

Hello All,

This can’t be the right answer, but to me DX is any countries that are not Canada since this is where I live.

My understanding of DX with the amount I have done is anywhere our side our country thats what I have always been told. I’m originally from New Zealand and we are just one big country so anything outside our country is DX. I now live in Australia again one big country but we have serveral states here and its a large country. But I still consider DX outside the country I’m living in. So when I talk to my friends back in New Zealand it is DX to my as I’m using my VK callsign not my ZL callsign.

So if I lived in Canada then a contact in the USA would be DX and if I lived in USA anything outside of USA would be DX

So DX in my opioion should be anything outside of the country no matter the distance.

This is just my point of view.

Thanks to everybody who answered my question so far. It’s interesting to read how differently DX is understood.

More feedback from OM worldwide is still very welcome.

I am living in a country in the size of a rectangle of less than 300 km x 200 km (185 x 125 miles). So on HF our neighboring countries are definitely not DX for us. :winking_face_with_tongue: @VK4NU
