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.
