At the radio station, an Icom IC-7300 is connected via USB to the Mini-PC. They are fast enough, optimized for low power consumption, come with a Windows10 license, and are affordable (~200USD). After two years, I still believe that these Gemini Lake Mini-PCs are an excellent choice for this use case.

Since RS-BA1 only runs under Windows, I opted for a Mini-PC with an Intel Gemini Lake CPU. For remote access, RS-BA1 Remote Utility uses 3 UDP connections. As you will read at the end of this post, the Remote Utility mixes parameters and makes implicit assumptions that are not documented. This is confusing, especially when you are trying to debug your setup. The Remote Utility implements the server and client-side at the same time. RS-BA1 Remote Control is the User Interface through which you interact with the radio.Ī Screenshot of the RS-BA1 Remote Utility softwareĪ Screenshot of the RS-BA1 Remote Control software The Remote Utility basically takes care of all the networking and radio setup. Icom’s RS-BA1 consists of two Windows programs. So if you are planning to buy the RS-BA1 software, make sure you buy version 2. As far as I can see, the main difference is that newer radios like the IC-9700 and IC-7610 with Dual VFO capabilities are only available in RS-BA1 v2. v1 (the latest version is 1.96) is most likely discontinued since this release dates back to 2018. It is also worth noting, that RS-BA1 exists actually in two versions v1 and v2.

There are some 3rd party alternatives available like VA2FSQ’s Win4Icom Suite, but they couldn’t convince me so far. It gets the essential job done to control your radio(s) remotely - however it lacks interfaces that are needed for the integration with 3rd Party software (like Logging or Digital Mode programs). In this post, I describe the symptoms, the tools I used for network debugging (on Windows), and the possible solutions.

During the setup, I stumbled over a few, mainly networking-related problems.

To access Icom Radio remotely (over the internet), Icom sells the RS-BA1 software.
