Astro Spectra Audio Howl
Posted: Sun Oct 30, 2022 4:19 pm
Fellow techies,
Has anyone ever seen a case where the VOCON module, in an Astro Spectra, causes a full-volume 'howl' in the speaker any time the audio is unmuted? This can be when changing the volume, receiving a signal, whatever... Swapping the VOCON clears the problem, but darned if I can figure out what component on said VOCON has failed.
At first I thought it was the audio PA, breaking into self-oscillation. However, swapping the command board has no effect. It's definitely in the VOCON.
Any ideas?
Thanks and 73...
