Hi all,

I have a Yaesu brand 2M mobile station that I used in a Toyota tacoma for 8 years without any issues. Recently I moved the unit and antenna to a Land Cruiser FZJ80 and have a buzzing sound that follows the engine RPM (i.e. if the engine RPM goers up so does the buzzing noise.) The only part that has changed between the installation in the Tacoma and in the FZJ80 is the coax cable was replaced.

Thoughts/suggestions on how to deal with this buzzing sound?

Thank you,
Sounds like alternator whine at first glance.
However, comb through this website: https://www.k0bg.com/ and repair/modify any parts of your install.
K0BG's website on mobile ham radio is the goto in the ham community and is a trove of great information.
