Why Logging Software?CW in 7QP2011 Results2011 Soapbox2010 Results7QP Home

Use Logging Software -- or Else!

Regardless of whether you are a newbie or have a wall full of contest plaques, everyone has to log their contacts in order to enter.   This year we have put a 40 QSO limit on paper logs.   That will remain until we find a log reader who really enjoys deciphering illegible handwriting, has better eyesight and more patience than I do.

What to do if you are still logging with a pencil? Get a logging program! (and a computer, if necessary...)It may seem like a big bother, but if you have never used electronic logging you are missing an amazing operating improvement.   Simply stated, a logging program will add to each entry you put in, the information it knows - like time and date, band, mode, and whether you have worked the station before.   How much it "knows" depends on whether your computer is also connected to your radio or you have simply manually entered this information already.   Some can also keep track of your DXCC score, look the station up in the callbook and write out a QSL!.   There are programs that just do normal logging, those that do contest logging, and some that can do both.

There are several very good free programs out there.   Some, like N1MM, are amazing in what they can do but have rather steep learning curves.   They are more difficult to install and fully master right.   Generally, however, they are useful right off the bat.   Rising to full use of all the features, like with any other software program, takes a while.    Others, like SuperDuper, Logger32 and CT are quicker to learn.   A good list of available software, free and otherwise, can be found at and   

One thing to consider -- logging programs are very much like word processing programs.   Once you learn one program, the command structure and function of all the others is very similar.   Contest operators who operate from different contest stations are usually competent on several different programs.   It's like driving a rental car -- it's different from yours, but the function and basic controls are the same, just located in different places.

Just like, except when it comes to output.   There are some differences in how the various programs handle log data.   Since one of the important functions of a log program is to keep track of who you have worked, you are really dealing with a real-time database.   Most programmers use "database engines" already available and adapt their program as an "overlay" for that particular engine.   It's much easier to take a working engine and modify it for radio logging than design the whole engine by yourself.   Database files are usually in specialized formats and undecipherable with a simple text reader.   Some programs put out an ADIF-formatted file for LOTW and such.   However, most all programs also provide for "plain text" output in the form of a text file.    This is what you send to the contest sponsor as your "log".

Since about 1999, a new standard log output format called Cabrillo has been used by the ARRL, CQ and most other contest sponsoring organizations.   It has a header with your callsign, personal information, contest name, and entry category.   The body of the file has one line for each contact.   Band, mode, date, time, your call, your exchange, his call, and his exchange are all there.   The benefit of this standard is that all the logs received in this format can be processed automatically -- scored, checked for validity (i.e.   zero points for duplicate or non-counting contacts), and verified.   Verification means checking for your call and exchange at the proper time and frequency in the other guy's log.   This file can be read and edited with any text editor.   This means that you get a neat, orderly, searchable log file with all your contacts, and the contest sponsor gets a log he can read into his log scoring and checking program.   You don't have to dupe your log, score it, or remove non-counting QSOs.

On the 7QP weekend there are at least four other contests going on at the same time.   How do you handle all that? If you are are only interested in the 7QP, it's easy -- log everything you work and attach your Cabrillo log file (or at least a clear text version of your log if your program does not support the Cabrillo format) to an email addressed to   But let's say you also want to enter the New England QSO Party because during the 7QP weekend you worked a whole bunch of W1-area stations who gave you exchanges like WORMA (Worcester County, Mass).   As long as you logged their complete exchange, simply send the same Cabrillo log to the NEQP sponsors.   Do the same for the Indiana QSO Party.   Why? Because the sponsors can easily electronically filter out the non-counting QSOs from your log and determine your score from the rest.

In state and regional QSO parties there is often a station operating from a county border or even a four-county corner.   If he gives you more than one exchange, what do you do? The best answer is to log it as multiple different contacts.   Some parties allow points for each contact and some do not - let them figure it out.   If they are new ones for you the multipliers will all count.   What if he's a mobile? You can work him every time he moves to a new county.   Most logging programs will not let you work the same callsign again on the same band and mode.   The easiest way is to log him as a new call like N7LE/des in Deschutes County and N7LE/cro when he moves to Crook County.   Your logger thinks it's a new call.

There's one small catch.   Most contest programs will only let you enter one contest at a time.   This means if you are in a state outside W7 and you chose the 7QP option on your contest program menu, the logging program might only accept contacts with the proper W7 area exchanges.    There is a fix for this.   Non-contest logging programs will let you log what is sent but they will probably not be able to give you a Cabrillo format output.   Most contest logging programs have a non-contest or general QSO mode.   In this mode you can enter exchange information "as received".    TR-log calls it WYSIWYG - what you see is what you get.   It will still log and check for dupes, even remember exchange from a previous contact on another band.   The problem now is how to get a Cabrillo output since you have told the program it's not a "contest".

A trick I've learned, for TR at least, is to save your log file, start another contest - one that has the current Cabrillo format, like the New England QSO Party.   Rename a copy of your log file so it is seen by the POST program as a log for the NEQP and ask it to output a Cabrillo.   Edit the header line for the contest name and category, and send it to the sponsor.   There is a detailed procedure for this on the web site.

Even if you cannot get a Cabrillo output from your logging program, the contest sponsors will be happy to receive your log in plain text electronic format.   And I can put away my glasses.

Dick, K4XU
