Abstract: HD 168112 is a non-thermal radio emitter that has only recently been confirmed as a spectroscopic binary by Putkuri et al. (2023, DOI: 10.1093/mnras/stad2657). We use an independent set of spectroscopic observations to determine its orbital parameters. We also analyse radio observations we collected around its periastron passage. While other orbital phases clearly show non-thermal emission, the phases near periastron are thermal and are dominated by the free-free emission in the colliding-wind region.
