The ACMA said in a brief statement on Wednesday that it had "not endorsed" a third-party interference management tool called QRM Guru while warning that any claims about it endorsing any such tool are false.

“While amateur radio user groups may develop tools for self-diagnosis and can use them to manage interference, the ACMA will not endorse or promote any specific interference management tools,” the regulator said.

“Amateur radio users may wish to approach their industry body to find out whether there are interference management tools they recommend,” the ACMA suggests.
