Preparations for using the IC-7760 with the HDSDR application
The IC-7760 can output the In-phase/Quadrature (I/Q) data that is processed by the FPGA. Connect the [USB]
port on the RF deck's rear panel to a PC's USB port, and you can control the IC-7760 from a PC using the HDSDR
application.
Procedure outline
To use the RF deck's [USB] port as an I/Q port for the first time, follow the steps described below.
For the settings and operations of HDSDR, see the document "IC-7760 HDSDR Operating Guide," which can be
downloaded from the Icom website.
Before you start using the IC-7760 with HDSDR, check the PC system requirements, as shown on page 2.
Step 1. Installing HDSDR
NOTE: First install HDSDR before installing "IC-7760 USB I/Q Package for HDSDR."
You can use HDSDR (freeware) as an SDR application.
Download HDSDR (Version 2.80 or later) from the HDSDR website and install it.
https://www.hdsdr.de/
When using CW Skimmer, install the other required applications to suit your operating needs. (pp. 3 ~ 4)
Icom does not offer technical support for your PC settings or any use of 3rd party applications.
Step 2. Installing "IC-7760 USB I/Q Package for HDSDR"
CAUTION: DO NOT connect the RF deck and a PC until the driver installation has been completed.
To control the IC-7760 from a PC using HDSDR, download "IC-7760 USB I/Q Package for HDSDR" from the Icom
website, and install it.
https://www.icomjapan.com/support/
The package contains "ExtIO_IC7760.dll" and an IQ driver.
The DLL file is normally saved in the same folder where HDSDR is installed as the default.
(Example: C:\Program Files (x86)\HDSDR)
Step 3. Connecting the IC-7760 and a PC
Connect a USB 3.0 cable (User supplied) between the [USB] port on the RF deck's rear panel and one of your PC's
USB ports, and then turn ON the RF deck and controller.
This document describes only hardware connections.
Step 4. Using HDSDR
See "IC-7760 HDSDR Operating Guide" to use the application with the IC-7760.
This document gives 4 examples to control the IC-7760 from a PC using the HDSDR application. (pp. 3 ~ 4)
TIP: Updating "IC-7760 USB I/Q Package for HDSDR":
If you already have the package installed, you can download the latest version and update it by doing an overwrite
installation.
