6m AS A DX BAND: 6-metres is a DX band just like any other of the amateur radio high frequency DX bands and it, along with other 6m operators, should be treated with respect and tolerance.

LOCAL BAND PLAN: Always respect your local band plan. In Europe this is issued by the IARU and is attached as Addendum (1).

LOCAL QSOs: Do not cause nuisance and disturbance to other dedicated 6-meter local and overseas DX operators with local QSOs within the 50.100MHz to 50.130MHz DX Window. If you do wish to local rag-chew, it is recommended that you do this above 50.250MHz where interference will be minimised. Note: Please remember in Europe that French operators are not allowed below 50.200 so local QSOs held just above 50.200 could affect their ability to work DX.

LEARN TO LISTEN: True 6-meter DXers spend about 5% of their time transmitting while 95% of time is spent listening and observing changing band conditions and propagation modes. Learn to recognize propagation mode characteristics and when the band is likely to be showing signs of an opening. This will be far more effective than just calling CQ DX at random and ad infinitum.

50.100 - 50.130 DX WINDOW: The DX Window is widely accepted concept and should, in principle, be used for INTER-CONTINENTAL DX QSOs only, especially the 50.110 calling frequency as discussed below. The definition of what constitutes a 'DX' station naturally lies with an individual operator, especially when a particular station within your own continent constitutes a new country! We would ask you to think carefully before having any intra-European QSOs in the DX window. For those of us in Europe, this is especially important in periods of multiple-hop Es or F2 propagation to avoid burying inter-continental QSO opportunities under a layer of European QRM. PLEASE BE SENSIBLE and avoid local QSOs in the DX window if at all possible!

As the DX Window is heavily used, always listen before you call and always ask if the frequency is being used before you transmit (should be done on any frequency anyway). Just because YOU can’t hear anything, it does not mean that the frequency is not occupied or some rare DX is using it. Remember that operating etiquette calls for you to ask if the frequency is occupied BEFORE calling CQ.

50.110 INTERNATIONAL CALLING FREQUENCY: The international DX calling channel is 50.110MHz. This should be used for long range DX contacts and such contacts should be inter-continental (outside of your own continent) in nature. Do not under any circumstances engage in local continental QSOs on this frequency even for a minute or two. If a local station returns to your CQ, move quickly to an unused frequency above 50.130MHz. Do not use the DX calling channel for testing or for tuning up your radio/antenna.

Do not encourage pile-ups on 110. If you have a successful CQ ensure that you QSY elsewhere in the band.

50.110 CQING: LISTENING is the first rule of working rare DX on 6m. So think twice before calling CQ on 110. It would be stupid to say that you shouldn’t call CQ but please remember that this is a shared frequency so your reputation will be on line if you insist on calling CQ unceasingly every minute of the day or throughout an opening - even if you do say "CQ DX only" or "CQ outside of my continent only". The occasional CQ is good as it can discover an unrecognised opening.

If you are a 6m DXer and have been intensely listening for weak exotica for hours on 110 and up pops a CQ caller, rather than ask him rudely to clear off, ask them POLITELY to QSY and TELL THEM WHY OR WHAT YOU ARE HEARING OR LISTENING FOR, and please GIVE YOUR CALLSIGN. Of course, this applies equally well to any frequency on 6m. Most operators are sensible and will do so – probably because they would like to work the DX themselves! Conversely, if you call CQ or are occupying 100 and someone asks you politely to QSY and GIVES YOU A REASON do so without arguing about the rights of doing so - remember that that you share this resource with thousands of other operators.

If you really must call CQ on 110, think twice, listen for five minutes, cross your legs, count to 100, and if the overwhelming desire is still there go ahead and CALL - but keep it short! At the end of the day the choice is yours and yours alone. Don't forget to QSY when successful unless it is inter-continental DX!

QSO TECHNIQUES: Many operators do not take the time to learn how to DX, develop QSO skills and techniques and jump right in. This is not to be recommended as typical 6m propagation does not allow wasting of time during DX QSOs due to the nature of propagation of the band (borderline HF/VHF). Openings could be very short in time duration and DX stations wants to work as many callers as they can during an opening.

Basically, follow the style and take the lead of the DX operator in providing information. Otherwise keep it simple and to the point as there are other stations who are also waiting in line for a QSO with the DX station. Do not waste times in exchanging unnecessary information such as locator codes, names, QTH, equipment, weather and so on. Just exchange your call signs and confirm your signal reports and move on to allow other DXers to have their QSOs. Leave out all the extra information (such as Maidenhead squares) unless it is requested. Many opportunities to work a DX station are extremely short and if your operating practices prevent others from working the station it will be remembered by those who missed out for a long time. Next time it may be you who misses out.

For more details about how to be successful in 6m pile-ups read 'Working Pile-ups & CQing on 110'.

DX PILE- UP OPERATING: Working and breaking DX pile-ups can be a frustrating experience on 6m as it is on HF. Manners and good operating are very important. You should listen to the DX stations carefully and not continue to call if they request a particular country or prefix to go back to them if that is not you. You should always go back with your complete callsign, give it quickly and give it only once. There is nothing more frustrating and aggravating for others in a pile-up to you to double with the DX station and miss who they going back to. Of course, you should NOT call if you cannot hear the DX station!

If a QSO is uncompleted due to QSB or QRM, don’t continue to try and complete the QSO to an excessive degree, use your judgment and call back later. It is likely that others are hearing them OK and can complete a QSO. Take the lead from the DX station and don’t call back immediately if they are working someone else. The message is simple, try to avoid calling over the top of the DX station – it does you no good and just upsets your fellow DXers.

SPLIT FREQUENCY OPERATION: When a DX station creates a large pile-up of stations all calling him on their own operating frequency (simplex operating) it creates tremendous QRM problems for those calling and the DX station. Under these circumstances, it is recommended that the DX station uses split operating; that is transmitting on one frequency but listening over a range of frequencies above the frequency being used by the DX station. This mode of operating will significantly increase the QSO rate of the DX station.

However, split operating on 6m can cause TREMENDOUS interference with other DX operators who, through no fault of their own, are running a simplex pile-up in the same split-frequency section of the band. To minimise this interference, it is recommend that a maximum split of 10KHz (definitely NOT 100kHz) is used.

DUPLICATE QSOs: It is always tempting to call a rare DX station every time you hear it. This should be avoided as it means that you taking away the opportunity for the DX station to work a new station and give them their first QSO with the DX country. Use your judgment if the DX station is known to be rare! Conversely, a quick call can sometimes be useful if no one else is going back to the DX station to show that there is propagation.

CW OPERATION: CW is probably the major mode of operation on 6-meters due to the usually weak nature of many real DX openings. Do not call a CW DX stations using SSB as they will not be able to hear you and you will be causing severe interference to other CW DXers trying to work the station. The contrary is true as well, if you cannot break a SSB pile-up using SSB then do not call using CW!

FM QSOs: All FM transmissions should be made above 50.500 MHz for the obvious reason that FM is wide band and could wipe out weak DX signals. There is no acceptable reason to transmit FM below 50.500 MHz, as there is plenty of spectrum allocated for this purpose.

Notes: This Code of Practice may be amended by UKSMG, JAROC & HARDXA from time to time to reflect current licensing conditions and operating practices.
