When using my VRS 750 connected to an Astro Spectra there is a 50 Hz tone generated when I unkey my portable radio. the tone lasts a second or two. Tone may not be that exact frequency. What is the purpose of this tone and can it be disabled? It sounds terrible on the receiving radio. When I have my VRS set up to monitor BOTH I hear it on my Astro speaker and on the remote receiving radio.
