USB Charging Ports vs Escape Installed Boss Radio
I just discovered that the USB charging ports that Escape installed in at least my December 2018 19’er makes a lot of RF (radio frequency) noise on the radio.
Ever since we picked up the trailer in early December, I’ve noticed the radio seems to have static, like the FM signal is weak or there’s a poor connection with its external antenna. Well... I just plugged my iPad into one of the USB charging ports installed by ETI and the radio audio degraded significantly. Then unplugged it and the degraded audio went away. And with my iPhone the degraded signal was less. So the interference / degraded audio appears to be proportional to the strength of charge being done by the USB charging ports.
It no doubt has to do with the voltage regulator in the USB port. Maybe an electrical engineer out there can explain why.
In any case, if you’re in a marginal radio reception area and want to listen to your Escape installed Boss radio, you might unplug any items you’re powering with the USB charging ports.
