Ham Radio Deluxe (HRD) provides the basis for all computer-aided operation in my amateur radio station. HRD provides an interface that can be customized to control the main station transceiver using the Computer Aided Transceiver (CAT) interface. The Rig Control component of HRD allows for the organization of buttons sliders, and drop-downs to toggle radio options, select modes and filter settings, and control various level inputs via the main station computer (HP Envy 23) running 64-bit Windows 8.1 Pro. The RT Systems USB-63 cable is used for CAT control as it is required for use with the RT Systems FTDX 1200 Programmer software.
I use the Logbook component in HRD for all station contact record keeping. I routinely reconcile records in the local logbook with the ARRL Logbook of the World (LoTW) and the Electronic QSL Card Centre (eQSL.cc) to record details of all confirmed contacts. I use Microsoft SQL Server as the back-end relational database for the HRD logbook to provide a more robust system with better concurrent access from other workstations and applications.
I have always had an interest in the digital modes of operation. In fact, when I was first licensed, I used teleprinters and terminal units for Radioteletype (RTTY) operation. Home brew microcomputers running operating systems like CP/M and some elementary software soon replaced the teleprinters. These days I use the Digital Master (DM-780) component in HRD for operation on digital modes such as RTTY and PSK31. A Yaesu SCU-17 USB interface is used to connect the main station computer with the FTDX 1200 station transceiver RTTY/Data port. The interface has a USB audio system for TX and RX audio that is accessible through the USB cable, and a two-channel USB serial device that enables various transmit modes.
Antenna azimuth control is performed by the PstRotatorAz program from Buda, YO3DMU. This software allows the antenna to be pointed by mouse click on the Azimuth graphic area (compass rose), by using the left and right keyboard arrows, by setting the azimuth, by setting the QTH locator (4, 6 or 8 digits), by mouse click on a map, by selecting the DXCC entity or by typing a prefix or full callsign.
