Fascination of QRP and DX

Attention! The informations specified on this webpage can lead to a massive infection with QRP bacilli. As consequence arise usually strengthened homebrewing, spontaneous QRP activities and a generally increased joy in the hobby. Note, that so far still no effective remedy was found against it. So reading on serves on own risk.


If you hears for the first time the term QRP, perhaps some questions occur. I hope that I can answer some of it on this page. And you will recognize, that also QRPer do not renounce the joy to reach a DX station. Many referring on this webpage apply of course also for the otherwise normal 100 W stations. However they should be considered strengthened by QRP stations. After all with 1 kW nearly each ham can reach a DX station in a pile-up.
line upwards What is QRP operation and what should I consider with it?
 
QRP is primarily an abbreviation from the telegrafie with commercial radio services. It means "Reduce you the transmitting power!" or as question formulated "Should I reduce the transmitting power?" The term QRP is used by the hams, for thereby to refer to the special mode of its radio station. QRP mode is the transmit mode with low power: 5 W output for CW, 10 W output PEP for telephony.
However it is not possible to achieve the 5BDXCC with a matched wet tying lacing and an 1 mW transmitter. It is however possible to achieve with some watts each point of the earth. It believes calmly! Perhaps my following tips help you to improve your operation mode. Because it does not only lie at the used station.

In principle a QRP signal should be clean! It does not help anyone, if the own CW signal going into the air with buzzes, clicks and chirps. Corresponding to it a SSB signal should be sended with a solid frequency and well modulated. Everything else compounded the recording at the strived QSO partner. A quiet, but clear signal is always better to receive than a loud one, which is to be taken up only with difficulty. If you uses with CW an electronic key, you can forget the wight controller confidently. You should pay attention to the rules for structure of a CW character. An 1:3 relation of dots and dashes facilitates very the recording. Spaces in and between the individual characters should correspond also to the rules. An endless worm of dots and dashes displeased only the listener and he will turning at his VFO knob.
 
As a matter of principle QRPers should also use a large antenna in a large height as possible! There QRP does not differ from QRO. It is guaranteed also possible to become apparent with an indoor antenna or a loop. However the number of QRP QSOs will rise, if you uses a better antenna. It objects that you may not structure an antenna, applies with me only rarely. On the one hand you can build up a wire nevertheless somehow outside of the room, on the balcony or to a road-side tree which is situated opposite. On the other hand you can in most cases stow its QRP station away due to its size in one backpack and become active with enormous antennas in free nature in such a way. I am QRV with a antenna on the balcony, which I build up only if I use the station. This "from time to time" use had means induced (otherwise rather heartless) landlord to giving in. If he had not agreed, then next the tree in the garden of the neighbour would have been the target for a long wire.
 

There are some good Antenna Rules of Thumb by Jim Duffey, KK6MC (aka Dr. Megacycle). You can find the original "Antenna Rules of Thumb" on KK6MC's webpage.

upwards Where can I receive assistance?
 
In principle with each ham. I met still nobody, who did not help me on a question (also special QRP questions). If you want to ask others QRPers, the QRP meetings, the QRP clubs and working groups or familiary other QRP stations are a very good address for it.
 
Additional you can meet QRPers on the amateur radio bands themselves. There are frequency ranges on the amateur radio bands, on which you will find strengthened QRP stations. These are the QRP frequencies. These are non of the IARU determined areas, although they at least for the region 1 were held now also in writing. They formed rather from the operation. Thus also no right to the exclusive use of these frequencies exists. It should be understood rather as "activity center" and not as frequency channels.
 

CW: 1843 kHz, 3560 kHz, 7030 kHz, 10106/10116 kHz, 14060 kHz,
18096 kHz, 21060 kHz, 24906/24910 kHz, 28060 kHz
SSB: 3690 kHz, 7090 kHz, 10140 kHz, 14285 kHz,
18130 kHz, 21285 kHz, 24950 kHz, 28360 kHz

 
If you see an antenna somewhere in free nature, on a camping site or in another unusual place, it concerns itself mostly over QRPers. Ask the owner calmly. But caution! Most discussions with QRPers last for a long time. But they are in addition rarely uninteresting.

upwards What are DX station, how do I find these and how reach I these?
 
A station is called DX station, which is distant for at least 3000 km from the own station. This rule is amended however particularly in contests, so that as DX station counts who is not located on the own continent. But consider that also you can be for other stations a DX station. At the time there are DXCC Entities. But also a QRP station can reach DX stations, as you show my DXCC results reached until now. If you should hear a callsign, which you cannot assign to a DXCC entitie, then look up in the list of callsign series. Thus you find at least the country, to which it belongs politically.
 
Only rarely you do find DX stations over the DX cluster! If a really rare station were called there, there is mostly a large "run", with which QRPers mostly must attach. It is however always worthwhile itself to hear the first 25 to 30 kHz of a band repeatedly after DX stations. If you working on the QRP frequencies, then turns every few minutes over this area. That lasts not for a long time. Quite often I so already got DX stations in the log, which began even only with their CQ or with those the pile UP were still small. Why the DX stations are there I cannot say. They are however mostly there.
 
Also QRP stations can "crack" a pile up. But it requires patience! Since it is not possible to put still fast few hundred watts more on the antenna you must be able to be occur in something else. As the first you should take of the notes for a operation mode and for the technical demands already specified. Beyond that you should sound oneself times the behavior in a pile up. It in most cases gives after the last passage of the DX station (with TU or K terminated) a mad confusion. Then something silence, because all hear whether they are called. Then it goes again from the front loosely. This break is the chance for quiet stations. If the DX station does not make a split operation, then it is advisable to call additionally something off the frequency. Most stations call directly according to experience or briefly apart from the DX frequency. There however nobody hears a QRP station. 500 or 1000 Hz beside it are already somewhat calmer it. Also with split operation you should not select the thickest tumult. Since the pile up is mostly quite broad, you should select yourself a calm place to the edge. QSK is there very helpful. Which you should not make however, calling is during a passage or continuous calls. That leads with some stations to the ignore of the call (and to the own annoyance). At some stations I already sat almost one hour on the station, before I was heard. Don't give up too early! QRO stations are doing sometimes exactly the same.
 

Some very good Thoughts on Working DX are publisched by Jim Duffey, KK6MC (aka Dr. Megacycle). You can find the original "Thoughts on Working DX" on KK6MC's webpage.

upwards QRP Hall of Fame
 
QRP Amateur Radio Club International The QRP Hall of Fame (QRP HoF) is an honor bestowed by the QRP Amateur Radio Club International (QRP ARCI) on people, who have made outstanding and long running contributions to the QRP community.
 
The call for nomination letters goes out in the autumn, the voting on candidates is done in the spring, and the new inductees (if any) are announced publicly at the QRP event "Four Days In May" within the Hamvention at Dayton/Ohio. Although administered by the QRP ARCI, membership is not required to be nominated or to submit a nomination on a worthy individual. The inital round of inductions was done in 1992. The program was revitalized in 1996 and there have been people inducted almost every year since.
