@DrGene seems to be gone now, but I want to ask about your experiences with the RFI from Tesla vehicles. I have a Model X Plaid and it operates mostly 7MHz. I have a Yaesu FT-891 (50W) with a Diamond 7MHz mobile whip antenna mounted on my upper trunk lid with a motorized K9000 mount. I'm getting almost no RFI while stationary, but the noise level goes up to S5-S6 when the car moves regardless of speed. The preamp (IPO in Yaseu's terms) is turned off.
In this thread, Dr. Gene mentioned that he doesn't have an RFI even when his Model 3 is moving. I want to reduce RFI while the car is in motion.
I have done the following tests:
- There's no noise if I remove the antenna from the car. The noise seems to be coming through the antenna, not from the body or chassis.
- If I drive the car slowly, the noise gets minor, but from 10mph and above, I get the same S5-S6 level noise.
- I put a DC line filter before the radio's 13.8V, almost no change.
My DC line is wired like this:
Accessory socket - DCDC converter to 13.8V - DC Line Filter - FT-891
