  The Galactic source G2.4$+$1.4 is an optical and radio nebula containing an
extreme Wolf--Rayet star. At one time this source was regarded as a supernova
remnant, because of its apparent non-thermal radio spectrum, although this was
based on limited observations. Subsequent observations instead supported a
flat, optically thin thermal radio spectrum for G2.4$+$1.4, and it was
identified as a photoionized, mass-loss bubble, not a supernova remnant.
Recently, however, it has been claimed that this source has a non-thermal
integrated radio spectrum. I discuss the integrated radio flux densities
available for G2.4$+$1.4 from a variety of surveys, and show that it has a flat
spectrum at gigahertz frequencies (with a spectral index $\alpha$ of $0.02 \pm
0.08$, where flux density $S$ scales with frequency $\nu$ as $S \propto
\nu^{-\alpha}$).
