A collection of DX resources and information, adapted from
a similar page that I did about a decade ago for the Iowa City ARC web
site. -KØCF

DX Bulletins
- 425 DX News
- Edited by Mauro Pregliasco, I1JQJ
& Valeria Pregliasco, IK1ADH.
A DX news site from Italy, with a weekly bulletin available via free email subscription. Usually arrives on Friday. Subscription includes a DX Calendar. - The Ohio/Penn DX Bulletin (OPDX)
- Edited by Tedd Mirgliotta, KB8NW.
OPDX has ceased publication effective October 31, 2022. - DX News Letter (DXNL)
- Edited by Klaus Poels, DL7UXG.
- A good DX information source from Germany. Also available via a free e-mail subscription.
- The Daily DX
- This is a paid DX newsletter, which arrives each weekday, with extra editions for rapidly breaking news. Bernie McClenny, W3UR, is the editor (and is also DX editor for QST magazine). A two-week free trial is available on the web site. Rates are currently $28 for 6 months, or $49 per year. (It is well worth the cost! -KØCF)
- ARRL
DX Bulletin Archive
ARRL DX Bulletin Subscriptions - Another source for DX information. As with the above newsletters, this is available via e-mail subscription on the ARRL "Newsletters" page. It comes every Thursday afternoon.
Available on the front page of this website, it is published every Sunday. This bulletin is a compilation of currently active operations only, gleaned by permission from other DX bulletins. Email notification is available to members of the EIDXA via our Google group mailing list.
Other DX Information Sources
- ARRL DXCC Program
- Most everyone who chases DX is after the DXCC award, or endorsements to it. Here is the site with all the rules, "entity" (i.e., country) list, entry forms, FAQ, etc.
- DX Summit
- Finnish web resource for DX information, including live DX spots from all around the world.
- NG3K Amateur Radio Contest/DX Page
- A great source for scheduled DX operations, both for general DX and contests. (Even if you are not a contester, DX contests are a great time to pick up new countries.) Also a tremendous collection of links for all things related to DX.
- DXWorld.net
- Features one-page graphical depictions of on-going DXpeditions. Nicely done site with beautiful photography. (Suggested by WØGXA.)
- The Complete DX'er -- by Bob Locher, W9KNI
- Far and away the most popular DX book ever written, "The Complete DX'er" is both the highly entertaining diary of a serious DX chaser, and at the same time full of lessons for DX'ing success. Written in a warm, personal style, this is a work you will read again and again. It very much respects and honors the traditions of DX'ing, yet brings a sense of excitement to the chase. $19.95 plus S/H.
QSL Information
- Logbook of the World (LoTW)
- This is the ARRL's
online logbook. Once signed up, you can upload your logs to LoTW. When
the DX you have worked uploads his logs, a "QSL" is generated. You can
download your QSL records to import into your computer log to show them
as confirmed. You can then submit these "QSLs" for DXCC, either a new
award or endorsements to an existing one. The only charge for using
LoTW is when you file to use the LoTW QSLs to apply to your DXCC. The
cost is much less than getting a paper QSL and submitting it.
Inaugurated in September 2003, LoTW, as of September 2021, has more than 1.3 billion QSO records on file, with more than 293 million QSL records resulting. The system boasts almost 150,000 registered users.
Users of the ARRL's Logbook of the World may also apply their LoTW credits to applications for the League's Worked All States (WAS) award. (US Amateur Radio licensees must be ARRL members to apply for the WAS award.)
Some CQ Magazine awards are available through LoTW as well. - IK3QAR QSL Manager Lookup
- From Italy, perhaps the most complete source for QSL managers. If you are not aware of QSL managers, they are volunteers who take care of QSLing chores for busy DX stations. Often, they are in the USA, so a QSL only costs two 58¢ stamps, (one on your outer envelope, one on your SASE) instead of a $1.30 airmail stamp and two US dollar bills!
- Zero District QSL Bureau
- The QSL bureaus provide an inexpensive way of getting your DX QSL cards. You send $6.00 to the bureau to buy 5 envelopes with one 58¢ stamp on each, plus 8 extra stamps (at 20¢ each). When an envelope gets full of DX QSL cards, they mail it to you. A good explanation of both the incoming and outgoing QSL bureaus is available at the ARRL's Incoming QSL Bureaus page and the Outgoing QSL Service page.
How to QSL

- How to Improve your QSL Returns -- from ZS6EZ
QSL card printers
- Some sources for your own QSL cards. Thanks to Rich
Haendel, W3ACO, for researching the data
in this table. Rich uses (and HIGHLY recommends) UX5UO for his QSLs.
Prices are current as of September 10, 2021 and are subject to change.

Propagation
- N6RT's Propagation Page
- Excellent near real time propagation information collected from numerous sources.
- ARRL Propagation Bulletin Archive
- ARRL's excellent weekly propagation bulletins by K7RA. Available by free email subscription on the ARRL web site, as well as in the archive page linked here.
- NOAA GOES 1 min & 5 min X-ray Flux
- NOAA's plot of solar X-Ray flux, a measure of the intensity of ionization in the earth's ionosphere. Updated each minute, shows 6-hour and 3-day spans.
- NOAA Planetary K Index
- NOAA's plot of the geomagnetic K-index, a measure of disturbances in the earth's magnetic field, which is detrimental to HF propagation. Auroras often appear when the K-index is very high. Updated every five minutes, shows a 3-day span.
- Near-Real-Time MUF Map
- A very nice world map showing the Maximum Usable Frequency (MUF) over the entire globe.
- NOAA Space Weather Prediction Center
- A nice collection of NOAA propagation data. Links provided to other NOAA pages. They have a nice collection of charts.
- SpaceWeather.com
- Very nicely done site, with lots of information about space weather other than propagation-related info.
- SolarHam.net
- Provided by VE3EN. A lot of propagation-related info in one place. Very attractively done! (Suggested by KØVM.)
- VOACAP
- A very useful and elegantly designed propagation forecast site. You select both ends of a path, antenna type and transmitter power. The results appear on a world map and a 24-hour wheel that shows path reliability by band. A must-see resource!
- WM7D's Solar Resource Page
- A nice collection of propagation data by WM7D.
Contest Resources
WriteLog Prefill Files
As a service to contesters who use WriteLog, I am making available Prefill files (often called "call history files") for contests where they are applicable. Please note that I am not the source of the data used to create these files -- that data comes from the N1MM+ call history site, maintained by Claude (Dub) Du Berger, VE2FK. If you have corrections or updates, please contact VE2FK.
The N1MM+ call history files are plain text files, which I have converted to ADIF (Amateur Data Interchange Format) for use with WriteLog. ADIF files are formatted text files that you can open and read with any text editor, such as Notepad. You may find it interesting to take a look at them.
If you need a prefill file for a contest that is not listed here, please send an email to k0cf (at) arrl dot net, and I will create one for you, if possible.
This list is sorted by contest name. The date shown is when the file was created, not the date of the contest. The files are all ZIP files, from which you must extract the .adi file.
After extracting the .adi file, start WriteLog, start a new log for the selected contest, then go to the "Tools" menu. On that menu, select “Preset Exchange from ADI file…”, browse to the location of the .adi file and load it. To test it, you can type in a callsign from the .adi file and the received exchange should auto-populate when you hit "space" or "tab" to leave the callsign field. Be sure to save your new log file; if you exit WriteLog without saving it, the prefill data will be lost and you will have to repeat this procedure.
Please note that the information in these files comes from logs from previous runnings of the contest. That information is subject to errors. Ops move, change their station power, or the exchange may have been incorrectly copied. Use the prefill information as a "suggestion", and be sure to log what your QSO partner sends!
