ICOM 7300 Memory Manager is an application for managing the memories of an ICOM 7300 HF radio transceiver using a Windows PC. It allows you to read and save memory channels directly to the radio, or to save the memories to a disk file for future editing or as a backup. If you like you can have different sets of memory channels saved to disk files, which can be quickly loaded into the radio for different circumstances. The Professional version adds the ability to have multiple memory channel windows open at the same time, and also gives you easy access to many of the radio's functions for customizing the screen, waterfall, scope, CW, RTTY, and filtering settings.

The following table outlines the main features of each version.

ICOM 7300 Memory Manager has been confirmed to work with the following operating systems and hardware:

Operating Systems

• Windows 10
• Windows 8
• Windows 7
• Windows Vista - has not been tested. The program will require that .NET framework be installed.
• Ubuntu Linux - works using Wine

USB Cables

I recommend the USB cable (USB A to USB B) connection to the radio. It is an easily sourced cable, and even though ICOM 7300 Memory Manager doesn't require higher speeds, this connection can support a higher baud rate than the CI-V connection. However ICOM 7300 Memory Manager will also work with a CI-V connection and an appropriate CI-V cable.

ICOM 7300 Memory Manager has been confirmed to work with the following CI-V cables

• CT-17 USB CI-V cable
• OPC-478 CI-V cable with a stereo to mono adapter
  Based on reports I have received, the OPC-478 requires setting a handshake of Request To Send, and checking both RTS and DTR in the advanced settings.

Try it with your hardware and software before buying

You can take advantage of our 14 day free trial for the Professional version to confirm that the program will work with your specific combination of hardware and software.

I do not own any other radios with computer control, so I have not tested this application with anything other than the IC-7300. Although the appropriate documentation is available for other radios, without the hardware to test with I am unable to ensure the application works correctly. Now if anybody is handing out radios for development and testing...😀

I have received one report that the memory channel editing feature of ICOM 7300 Memory Manager works with the IC-7610. Since I do not have an IC-7610 to test with I am unable to confirm this report myself. While the memory channel editing function should work, the radio options dialog of the Professional version will definitely not work with the IC-7610.

Using this application on other radios is not supported and should be done with caution.

Windows provides the ability to run a program, known as a screen saver, that will display a moving image, or even turn off the display when the computer has been idle for a period of time. The original purpose of a screen saver was to prevent monitor "burn-in" which would occur when the monitor displayed a static image for too long of a period. Although modern LCD displays are much less susceptible to burn-in, Windows has retained the screen saver mechanism.

Most typical screen savers will display moving text or paint pretty graphic patterns on your screen. Instead of simple entertainment, KB3HHA Screen Saver displays useful information and images and provides several different moving displays.

• An animated National Weather Service weather radar display and current weather conditions for your location
• The current National Weather Service forecast for your location in either 7-day or hourly formats
• The current space weather conditions that affect radio propagation along with animated images of either
  • The sun
  • Coronal Mass Ejections (CME)
  • An aurora forecast for the Earth
• An animated satellite view of the Earth along with some some basic astronomical events for your location.

The cost of the KB3HHA Screen Saver is $9.99 USD.

You can take advantage of our 14 day free trial to see if the screen saver meets your needs before purchasing it.

The KB3HHA screen saver supports multiple monitors. You can even show different displays on each monitor.

There are several ways to get to the screen saver settings in Windows 10. One way is to:

• Right click on an open area of your desktop. A context menu will be displayed.
• Select "Personalize" from the context menu. The Background Settings window will be displayed.
• On the left hand side menu select "Lock Screen". The Lock Screen settings window will be displayed.
• Select "Screen Saver Settings" (The bottom most entry on the Lock Screen settings window). The screen saver configuration dialog will be displayed

You can use the screen saver configuration dialog to select a specific screen saver and to change any configuration settings that screen saver offers

• Weather Radar and forecast
  • National Weather Service
• Space Weather
  • National Oceanographic and Atmospheric Agency
• Satellite
  • National Oceanographic and Atmospheric Agency
  • National Aeronautics and Space Administration
• Background Map
  • Wikiocity/OpenStreetMaps

The screen saver writes configuration settings to the Windows registry.

To minimize downloading static image files, the background map for the weather radar panel is saved to local storage after it has been downloaded the first time. The more volatile data and images (weather conditions and forecast, radar, satellite, and space weather) are downloaded on demand as needed from the Internet. An in memory cacheing strategy is used to prevent downloading the same images and data multiple times while the screen saver is actively running.

This software sets both the date and the time

Set7300Clock has a command line switch to use UTC rather than local time. See the documentation for details.

I currently only have PowerShell and C# versions. You can use either of them as an example of the logic required to write your own version. Also see the resources page for links to several pages with some good information on CI-V programming.

The CI-V command for setting the time only permits sending hours and minutes. In order to get the seconds correct the program waits until the second when the time rolls over to the next minute.

CI-V Scout is a Windows application that will display received CI-V messages on a specified serial port. It also includes a CI-V command builder that will help you build CI-V commands and then send them to a CI-V capable radio.

CI-V Scout is not a full radio control application. It is a tool to facilitate learning more about CI-V and to assist in building and testing CI-V data formats.

The documentation for your radio should include a CI-V reference section. It might instead be in a separate document. In the case of the ICOM IC7300 it is in a section of the full manual titled "Control Command". You will have to check your radio documentation or maybe even do some searching online.

When CI-V transceive is enabled in the radio it will "broadcast" CI-V data when the radio changes settings such as operating frequency or mode. This would be in response to actions such as a user turning the tuning knob. This feature can be used by software or other CI-V aware devices to track changes in the radio settings. One example would be a logging program that automatically logs the frequency and mode when a new log entry is added.

APRSViewer is an Automated Packet Reporting System client application. It supports sending and receiving APRS packets via a KISS TNC connected to a radio and also via the Internet (APRS-IS). Received packets are displayed on a scrollable and zoomable map. Dead reckoning and beaconing are fully supported for objects that are in motion.

Dead reckoning is a navigational method for estimating the current position of an object based on a previously determined position, or fix, and applying the last known course and speed over elapsed time to calculate the object's estimated current position.

Smart beaconing is an algorithm developed by Tony Arnerich KD7TA and Steve Bragg KA9MVA to dynamically determine when and how frequently to send APRS positrion updates. The goal is to minimize the number of position reports sent without losing precision when plotting those position reports on a map. The algorithm has been adopted by a number of APRS hardware and software vendors.
