Amateur Contact Log 4.0 is Now Available!

Home News

Hi All,

I'm really excited to announce that...

Amateur Contact Log 4.0 is Now Available!

To make a long story very short, when I first started writing software back in 1997, Visual Basic was a great programming platform that I used to create all my original software, but in the years to follow, Microsoft dropped support for VB6. To be sure that our programs continue to run well into the future, make them more maintainable and easier to code future enhancements, I am in the process of rewriting my entire software package in C#.NET and Amateur Contact Log 4.0 is now complete!

Amateur Contact Log Version 4.0 is a total rewrite of Amateur Contact Log. It has almost all the features supported in version 3.4 and lots of new ones that I think you'll really enjoy! Some of the new enhancements include:

- Fully networkable! Whether you want to use AC Log for a DXPedition, or you just want to access your log from multiple PCs simultaneously at your home or club station, AC Log will now support multiple clients updating a single database, just like my Field Day and other contesting software!

- Lots of additional and customizable data fields.

- AC Log is as easy to use on first install as ever, but if you want to customize AC Log, it is now even easier to configure the main form to your taste for fonts, colors, layout, tab order and fields displayed!

- Improved analysis and display of needed DX spots stations.

- Bulk uploads and downloads to / from eQSL are now supported.

- Addition of's free callbook Internet lookup service.

- And lots more!

AC Log 4.0 is Free to Registered Users!

As always, all of my software upgrades are free to registered users and AC Log 4.0 is no exception! You can download the latest from:

System Requirements:

Amateur Contact Log 4.0 requires Windows XP with Service Pack 3 or later. It also requires the Microsoft .NET 4.0 client framework, which is likely already on your PC, but if not, the installer will install it for you automatically. If you are running an operating system prior to XP, don't worry, I'll keep version 3.4 on the VB6 archive page here: in case you ever need to reinstall it.

Installation Steps:

AC Log 4.0 uses a completely different database structure, so it will not open your log file from 3.4 directly, but upgrading is a snap. Simply:

- Install AC Log 4.0.

- From your previous version of AC Log, click File > Export ADIF > Whole Log and save your file in a place that is easy for you to find on your hard drive.

- From version 4.0, click File > Import ADIF and select the ADIF file that you exported.

- If you have customized settings, you'll need to reconfigure them, but you'll find it to be a much easier process with even more flexibility in version 4.0!

By the way, AC Log 4.0 runs completely independently of the previous versions of AC Log, so if you are unsure if you want to upgrade, please go ahead and give it a try. Your existing installation will not be altered in any way and you can continue with the previous version if you prefer it for any reason. I think you will really like version 4.0 once you get a taste of it though!

For LoTW uploads from AC Log 4.0, you'll need to run TQSL software version 1.14 or later.

A Note to Blind Hams:

I've received reports from blind hams beta testing AC Log 4.0 that some screen readers are not doing as good a job identifying the fields as they did in the VB6 versions of AC Log. I don't have any screen reader software here and until I have the opportunity to investigate further, blind hams may want to stay with AC Log 3.4 for now. AC Log 4.0 does continue the feature I programed in 3.4 of correctly reading the current field with wave files.

Thanks so much for Testing and Input!

I want to extend a special thank you for all the testing, enhancement suggestions and input that so many of you offered during the development and testing phase of Amateur Contact Log 4.0. You all have made this version far better than it would have been otherwise and I can't thank you enough for all your help, patience and input!


So everyone, please give AC Log 4.0 a try and see what you think. I hope that you enjoy it!
