I have written a little callsign lookup program. It uses a small database that
is right on your hard disk (or cd) so it's real fast and you don't have to be online
to use it. I will provide weekly updates for your database, so you will only have to
download the full database once.
It will look up callsigns, or search by Name, City, State, or Zip.
callwin is for Windows. Dos and Linux versions are also available.
For more information see the
callwin help file
The US ham database has outgrown the max size i gave it 14 years ago. Progress, i suppose. To handle the larger number of hams, callwin+.exe and autoupdt.exe had to change. Thus you need to download the new versions.
They can be found in callwinplus.zip or callwin-all.zip
autoupdt.exe replaces autoupdate.exe and autoupdate+.exe
- renamed for win7/vista so the UAC doesn't ask you for permission to update
- it also works with or without zlib1.dll
- added help file
- You may continue to use autoupdate and autoupdate+
callwin/callwin+ has a new
since win7 and vista no longer support the old help file
- and it was embarrasingly out of date
For a new installation, create a folder on your hard disk, eg C:\callwin
and unzip it into that folder.
This file contains a recent complete database and the tools you will need to
use and update it (see below).
I suggest you create a shortcut to callwin.exe on your desktop.
Click on the shortcut or 'callwin.exe' and you're off and running.
Note: You only have to download the full database once.
After that, just use autoupdt.exe to do the weekly updates.
They are much smaller files, so the download time is minimal.
Feel free to distribute it for as much as it cost you (ie, nothing).
Put it on CD for those who don't have web access, etc.
Or if you ask real nice, I will send you a CD.
NOTE: The location and layout of the Canadian database has
changed as of 10/24/2011. autoupdt.exe rev 010 accounts for these changes,
and is included in the autoupdt.exe, callwin-all.zip and callwinplus.zip

or use autoupdt.exe to download the current

Updating your database
The autoupdt.exe program
will grab the updates you need and install them -- all with one click of the mouse.
You do need to be connected to the internet - or download the update files ahead of time.
The autoupdt.exe can also update the Canadian data, but requires the zlib1.dll
If you would like to receive a weekly update file via email,
The latest database is 9/17/2017.
The newest update file will be on the top row, right side.
See Changes note above - you must get the newest version of
callwin+.exe and autoupdt.exe to use the March (and later) undates.
Latest Canadian db 9/17/2017
To update your database:
The autoupdt program
(see help file)
will download any needed updates and update your database.
If you have a computer that is not connected to the internet, you can run autoupdt on
a computer that is connected and use the "sneakernet" feature of autoupdt to copy the
But if you need to download the update files manually:
- Run callwin and note the database date, eg 20051002. The format is yyyymmdd.
Note: The newer version of callwin shows the date as mm/dd/yyyy.
- The update files are named for the dates they update
- Eg, MMDDtoMMDD.db
- Each update file updates one week
- Begin with the update file that begins with the MMDD (month-day) of your database
- Download all the files from the first one to the most recent.
- Put them in the same folder as your call.db file
- Run autoupdt.exe. It will update up to 8 weeks at a time.
- If you are more than 8 weeks behind, just run it again until you are up to date.
