Eliminating Niose on Ham Radio Jeep TJ?
 

Hi Folks,

Has anyone had sucess eliminating Jeep TJ RF noise? Specifically, year
2000 or later? I grounded the tail pipe to the frame, installed .1uF
bypass caps on the fuel pump lead (to ground) and am still experiencing
noise on 2m/70cm. The bypass cap helped eliminate some noise, but I'm
still experiencing noise poportional to engine RPM.

Any insight appreciated.


Thanks,
Nick

Have you grounded the hood?
What kind of antenna/mount are you using?
Are you running both + and - directly from the radio to the battery?
Do you have a direct ground from the radio to the Jeep chassis?
Is the feedline coax grounded directly to the Jeep at the antenna end?
Do you know if the noise is from the ignition or the alternator?

Nick, where is your radio getting its power from? Does the noise go
away when you disconnect the antenna? Have you replaced your spark
plugs with non-resistor plugs?

Plus why the other guys said, try cleaning the battery terminals.
If you're using the chassis for your DC ground, run another wire
to your battery for it. Don't forget to fuse both sides.
