Amateur Contact Log 5.7, CQ WW RTTY 1.4, Interface w Fldigi, N7YG & H.R. 1301!

Home News

Hi All,

Just in time for CQ WW DX RTTY this coming weekend....

Amateur Contact Log 5.7 and CQ WW RTTY 1.4 are now available!

Dave, W1HKJ (author of Fldigi), Jeff, N7YG (author of PSK Express and Digital Engine) and I have been working really hard the past few months on the Application Program Interface (API) to N3FJP Software for their digital programs. To accommodate all the new features of their respective programs, I've added additional API commands to my software.

To set up my software to interface with these digital programs, start N3FJP Software first. From the menu options, click Settings > Application Program Interface and check the upper check box that says TCP API Enabled (Server). Leave the lower check box unchecked. Then start the digital program of your choice and refer to their help as needed (Configure > N3FJP Logs in Fldigi and N3FJP in PSK Express).

In addition to the new API commands (0.8), I've added a few other enhancements, including:

- Ability to quickly and easily switch between two rigs as configured on the rig interface form (Just press Ctrl X from the main form to switch between rigs).

- To clear the band map, click on the band map and then press Shift C (this only affects the band map, not the DX Spots list).

- Ability to add an offset on frequency change such as clicking on a DX spot, as configured on the rig interface form. When you click on a DX spot in CW, you may wish to be up or down a few Hz, so you aren't calling on the exact same frequency as everyone else. In digital, you may wish to specify the sweet spot of your waterfall pass band.

- To quickly display the frequency column in the QSO list in any contesting program, click Ctrl + Shift + F.

As always, these upgrades are free to registered users. Just uninstall the previous versions from Windows Control Panel and then install these:

More Contest Program Upgrades Coming Soon!

By far, the main emphasis of this AC Log and CQ WW RTTY upgrade is the digital interface integration. With these two now complete, Lord willing, I will begin updating the rest of the 100+programs with these latest enhancements after we receive feedback on how CQ WW RTTY goes this weekend. Dave, Jeff and I will do our best to stay ahead of this coming season's digital contest schedule.

The Latest Digital Programs that Interface with N3FJP!

Dave, W1HKJ has just released his latest version of Fldigi, which interfaces with my software! Fldigi is a widely used, free digital program, supporting a variety of digital modes. You must upgrade to Fldigi 3.23.14 to interface Fldigi with my software:

Fldigi 3.23.14:


And you will find the latest versions of Jeff, N7YG's free programs here. PSK Express is a full featured digital program that supports a variety of digital modes including RTTY, etc. N7YG Digital Engine is a scaled down version of PSK Express, specifically designed by N7YG to function as a companion to the suite of N3FJP software and provide users with a simple digital modem and floating waterfall, that can reside on the same screen as the logging software:

N7YG Digital Engine


Even if you are more familiar with one program than another, please try all the digital options! There are some differences that may make one more appealing to you. You may find one works better for contesting and the other for general rag chew.

Dave and Jeff have both been working really hard to make this happen, so please be sure to thank them both!

Other Programs Now Interfacing with N3FJP Software

In addition to Dave and Jeff's latest work, here are other programs that now interface with N3FJP Software:

JT Alert: (Digital bridge software emphasizing JT modes)

W4ELP Lookup Utility: (Interfaces my software with DM 780 - including the free version)

Win4K3Suite: (Rig Interface for Elecraft radios)

If you would like to see other digital programs interface with my software, you can help make that happen! Developers often add upgrades based on feature requests from their users and it may be your prompting that makes the difference! Please refer the developer here:
