    The cig lighter power cord for my dash cam caused RFI all over 2m. Installed a dual USB power port and have no issues now except on one repeater on 147.06 which I don't use often. Co-worker has the same issue with his dash cam and the same repeater, unfortunately that's his local repeater.

    I use the USB power port for the dash cam, to charge my phone, tablet, and TNC.
