JT65-HF

JT65-HF was built specifically as an amateur radio tool for receiving and transmitting the JT65A protocol, and comes packed with several predefined QRG (frequencies used by ham radio operators) and message definitions.

You are required to go through a smooth setup process which is over in a jiffy. Completing it brings you to a pretty cluttered interface, seeing that it consists of a menu bar, multiple buttons, several boxes and all kind of information all throughout the main window.

Moreover, there are no Help contents incorporated, which means that only experienced users will be able to find their way around this tool.

First and foremost, at the first launch, you are met with the settings panel, so that you can configure all the options to fit your preferences.

As a result, you can easily choose the sound input and output device from some drop-down menus, define a callsign, prefix, suffix and grid (4 or 6 characters), enable automatic RX/TX sample rate correction and select location of the RX/TX history file (CSV format).

In addition to that, you can add your PTT port and test it, call for a PSK Reporter or RB, add QRG and message definitions to an already existing list, and adjust the color-coded system.

A raw decoder is available, and it possible to view logs in a separate window and clear it with just a click of the button, while the main window displays the current hour and date, enables you to view audio input levels and adjust the digital audio gain.

It is possible to call or answer a CQ, answer a caller and send a report, change the color map and adjust the brightness, contrast, speed and gain.

The program does not put a strain on the computer’s performance since it does not require many resources in order to work properly, and the response time is good.

All things considered, JT65-HF is a pretty handy piece of software, suitable to power users which are passionate about amateur radio. Nevertheless, it could use an update in the interface department.
