[RFI] RFI - 2018 Jeep Wrangler

[Stephanie WX3K]

I own a 2018 Jeep Wrangler Sport unlimited. In general, I Love the vehicle.

I just finished installing the following gear for the first time:

Yaesu FT-817
Elecraft KXPA-100

I devised a custom mount for a 102” whip on the corner of the Jeep. FT817 is mounted on a slide mount where the dash tray is. I have a Yaesu FT8900R and DR235 installed along with a 10 watt Motorola amplified speaker for a number of years now. I designed a power pole distribution system for the rigs along with a audio distribution that combines all three rigs into the amplified speaker.

Today was the first time i tuned up the KXPA-100 with the FT-817 as I just finalized the interface cable that controls the amp from the 817. It works ! Bands were dead today though so no contacts. I can run full power on 17 with zero issues. On 40 meters, the RF gets into the anti-skid system and computer. Joy. I do have some audio RFI issues on 10 meters. 

Not surprising considering. Rather similar to issues i had in my 2003 Subaru Forester but on 40 the RF would completely stall the engine when the rig is keyed up.

I do have ignition “spark” noise and other hash noise on 40 meters and other bands. Again not surprising. I have done zero bonding on the hood to date so that is my first target. The antenna mount is bonded to the frame in the rear of the vehicle. 

I certainly have work to do yet.

Has anyone else worked thru RFI issues on a late model Jeep Wrangler ?
