SR10 Needs Ground-Loop Isolation
When the SR10 is powered from the bike, and connected to audio devices that are also bike-powered, ground loops are formed between the devices and any electrical noise present on the bike's electrical system is heard through the SMH10. When connected to both a radar detector and a two-way radio, the noise is strong enough to trigger the audio from the SR10.
Removing the devices from bike power eliminates the ground loop and the noise goes away.
