  • Q: What is LogView ?
    A: LogView is an online tool that plots the QSOs in a contest log on to a map of the USA or North America. You can see the QSOs all at once, or have them appear in log-order. You can turn bands on and off, and compare your QSOs with the published results for that contest.
     
  • Q: What kind of logs can I use with LogView ?
    A: LogView only supports logs in the Cabrillo-format. This is the format recommended by the ARRL, and is the format that you would normally use to upload a log after the contest.
     
  • Q: Where can I learn more about the Cabrillo format ?
    A: There are a number of sites online that explain the Cabrillo format.
    Two of the best are ARRLWeb-Cabrillo and kkn.net Cabrillo Standards.
     
  • Q: Does my log have to have a special filename or suffix for LogView to recognise it ?
    A: No. LogView will work with any filename and suffix; the important thing is that the contents must be in the Cabrillo format.
     
  • Q: What happens to my log after processing ?
    A: When uploading your log, if you answered 'No' to the question: 'Save Log on Server ?' then the uploaded log is discarded after processing. If you answered 'Yes', a copy of the log is saved on the Server, allowing EI8IC to use it when testing future versions of LogView. Your log will always be kept private, and will never be shared with anyone else.
     
  • Q: Are there any special tags that must be in the log ?
    A: Yes. LogView looks for the following tags:
    START-OF-LOG:
    CONTEST:
    CALLSIGN:
    END-OF-LOG:
    If any of these tags are missing, LogView will not be able to process the log. Also, each QSO has to start with the QSO: tag.
     
  • Q: Can I see an example of a Cabrillo log ?
    A: Click HERE to download a log of the 2004 ARRL CW Sweepstakes, made available by K8AJS - many thanks, John.
     
  • Q: What contests are supported by LogView ?
    A: ARRL-10 ARRL-160 ARRL-DX-CW ARRL-DX-SSB ARRL-RTTY ARRL-SS-CW ARRL-SS-SSB ARRL-VHF-JAN ARRL-VHF-JUN ARRL-VHF-SEP ARRL-UHF-AUG CQ-160-CW CQ-160-SSB CQ-WPX-CW CQ-WPX-RTTY CQ-WPX-SSB CQ-VHF CQ-WW-CW CQ-WW-RTTY CQ-WW-SSB IARU-HF NAQP-CW NAQP-RTTY NAQP-SSB RSGB-IOTA STEW-PERRY TARA-RTTY
     
  • Q: What contests do you have the results for ?
    A: ARRL-10 ARRL-160 ARRL-DX-CW ARRL-DX-SSB ARRL-RTTY ARRL-SS-CW ARRL-SS-SSB ARRL-VHF-JAN ARRL-VHF-JUN ARRL-VHF-SEP ARRL-UHF-AUG CQ-WW-CW CQ-WW-SSB IARU-HF NAQP-CW NAQP-RTTY NAQP-SSB.
    Most contests are covered since 2001.
     
  • Q: Will you be adding support for the xxx-Contest in future ?
    A: When the contest gets a standardised Cabrillo format, it might be added in.
     
  • Q: Can I save LogView for use offline ?
    A: As the LogView page is generated dynamically, it won't save as a normal web-page does.
    However it is still quite easy to use offline if you follow these instructions.
    You only have to do this once...
    1. Decide which screen resolution you prefer: 800x600, 1024x768, or 1280x1024
    2. Click on one of the above links to download the Zip-File (Version: v4.1 - 27th January 2011) - you can save the file anywhere on your computer; your 'My Documents' folder would be ideal.
    3. Start the WinZip program, click on 'Open', and browse to the downloaded file.
    4. Click 'OK' to select a file, then click 'Extract'.
    5. Leave the 'Extract to' box set to the present file location.
    6. Select the 'All Files' and 'Use folder names' options. (The folder-names option is absolutely required for the program to work.)
    7. Click 'Extract', and WinZip does the rest for you.

    OK - you now have all the files that a LogView page needs. Go to the Display Cabrillo Log page and upload your log as before. When the log is returned, and you are seeing a page beginning 'Log Status (Server processing time:...', click on File > Save As. A message may appear 'This web page may not save correctly. Would you like to save it anyway?' - just click Yes. Choose the LogView folder you've been working on as the 'Save in' folder, leave the filename as it is, and choose the 'Save as type:' as 'Web Page, HTML only'. Click Save, and that's it.

    To view the log offline, just use My Computer or Windows Explorer to browse to the log, and click on it.

  • Q: Why should I filter DX calls from my log ?
    A: LogView can only plot the positions of US and Canadian callsigns, because only the US and Canada make their full license database available. Any other callsigns are not plotted, and so leaving them in the log will only slow your download time.
     
  • Q: Why aren't DX calls shown on the map ?
    A: LogView can only plot the positions of US and Canadian callsigns, because only the US and Canada make their full license database available. If you know of somewhere that I can obtain callsign lists of other countries, please contact me.
     
  • Q: Will you be adding more maps ?
    A: Yes, if there is sufficient demand. Email me with your suggestions.
     
  • Q: What is the difference between the different resolutions ?
    A: The only difference is the size of toolbar, and how much of the log is viewable.
     
  • Q: W1XYZ operates from CT Why does his spot appear in Florida ?
    A: The position of a spot is based on the latitude and longitude of a station's mailing address Zipcode or Canadian Postal Code. There is no way to check if they are operating from a different location.
     
  • Q: How often does the callsign database get updated ?
    A: I generally upload the latest license data every 6 months or so, though as I am currently on the road, travelling around the world taking travel photos, the actual dates can vary. The latest license data is freely available from the FCC and Canadian licensing authorities, though requires some processing before it can be easily used.
     
  • Q: Are all ham licenses in the database current ?
    A: The actual number of ham database entries exceeds the current number of US and Canadian hams. When new license data is obtained, I overwrite existing address information for each current callsign, but I do not delete older callsigns that are no longer in use. This is to allow the mapping of contacts in older logs that you may still wish to plot.
     
  • Q: Why are some hams missing from the database ?
    A: I only include US and Canadian hams in the database who have submitted a valid Zipcode or Postal Code to their relevant licensing authorities.
     
  • Q: Why do the number of mults LogView displays differ from my log ?
    A: LogView plots W/VE calls only. Therefore, other calls are either discarded or filtered out. Because of that, for contests that include QSOs with stations outside of W/VE, the mults will never be the same as your full log, and so the decision was made to only count mults for contests that use state/province or sections, and to only count a mult once per log. There is no point counting mults per band etc, as the display could never show all the mults you actually worked.
     
  • Q: What is the 'Flag' column all about ?
    A: The Flag column shows how LogView processed each callsign. The characters have the following meanings:
    • W = Callsign identified as USA.
    • V = Callsign identified as Canadian.
    • D = Callsign identified as DX, so position undetermined.
    • C = Callsign not found in my callsign database, so position undetermined.
    • Z = Zipcode for that address was not found in my zipcode database, so position undetermined.
    • U = Callsign contains / so position unreliable.

     
  • LogView won't process my log. Why is that ?
    A: Like any computer program, LogView works from a series of rules. LogView needs to find various tags in your Cabrillo-format log: START-OF-LOG:, CONTEST:, CALLSIGN:, QSO:, END-OF-LOG:. If any of these tags are missing, LogView will not be able to process the log. Also, the log must conform to the standard Cabrillo template for that contest. These templates can be seen here: kkn.net Cabrillo Templates. There are also example-logs that you can look at. If your log has an extra column, such as RST in a VHF contest, LogView will not be able to make sense of your log. Similarly, a column missing will cause problems. If you still can't work out where the problem is, please email your log to me.
     
  • Q: Why don't the labels hide when I click the Label Box ?
    A: You may want to have some Labels showing for a log, but not others. To keep this versatility, the Label Box only controls what *will* happen, not what has happened. You can step through the log to, say, hour 5, then turn on the labels, step to the end of the hour, then turn them off. To clear all labels, uncheck the Label Box, then click on Start-Of-Log to go to the first QSO.
     
  • Q: I searched for a call that I know is in the log, but the Search didn't find it ?
    A: The Search function is case-sensitive. If you have W1ABC in your log, a search for 'w1abc' will miss it.
     
  • Q: Can you tell me a bit more about the dedicated Results Viewer ?
    A: The Results Viewer is an add-on to LogView: a dedicated tool that lets you create a map of contest results, and compare them to the results of other contests. To find the tool, click on the links in the 'Results' page, or locate it in any of the Offline Zip-Files. To use the tool, choose a Year and Contest on the top line. A tick or check-mark indicates which results are available. Click the tick, then choose to either 'Show All', or step through the results with the VCR controls. You can also load a second set of results for background comparison. These are shown in one color, for clarity. To find out what each contest-class is, click the 'L' button to bring up the map legend.
     
  • Q: Why aren't some of the contest-results shown on the map ?
    A: The only results that can be shown on the map are those where LogView can determine the correct position. The most common cause of missing results is when a callsign contains '/', such as VE3/W1ABC or W1ABC/P. This is especially true for the CQ-WW contests, where many stations use /zone_number. In these cases, it is not possible to determine the position automatically. If you know the correct position of any missing callsign in the result-tables, please let me know, and I will correct the plot-data.
     
  • Q: How can I find out what all the LogView buttons do ?
    A: To learn what each of the LogView buttons does, and to identify the various features of the program, click on the Screenshot.
     
  • Q: Why does the WinXP Information-Bar warn me about your web-page ?
    A: With Service Pack 2, Microsoft has tried to be helpful by introducing their new 'Information Bar', which appears below the normal toolbars of your Internet Explorer browser when it thinks there is a possible threat. In this case, it is alerting you to the fact that there is extra scripting going on, and thinks that you ought to know about it. Unfortunately for me and other web-designers, it does not mention when the scripting is JavaScript, which is safe and cannot access personal details, and the other types of more intrusive script. All the code used in LogView is JavaScript, and will not damage your computer in any way. All the code can be examined to prove this is true, so you need have no worries when using LogView.
     
  • Q: Can I suggest new features or enhancements for LogView ?
    A: Sure, that would be most welcome. Please email me at the address on the Contact Page of my website.
