There is now a dedicated international talkgroup on BrandMeister for all your tests: TALKGROUP 98.
You can test the audio on your new radio or software as many times as you want, for as long as you want, without worrying to disrupt a QSO.
If you like helping fellow digital ham operators, please stand-by on this talkgroup whenever you can to provide assistance and feedback.
73’s and happy tests on talkgroup 98 !
