911/996 TT noise from engine bay? Help
Hi,
I have a 2001 911/996 Twin Turbo that is a great car in all ways except fro when I went to put in a small dualband 2m/70cm transceiver for communications. On the frequency area I use the most which is around 146-147 Mhz, their is spurious noise actually pouring out of the engine bay area that registers an S9 level across the band. There are no issues on 400Mhz, just 146-147Mhz. The opposite applies, when I transmit with more than 10 watts in with the antenna anywhere near the back of the car, the engine dies so it sounds like RF is both being produced spuriously by the car computer and then being killed by the RF from the transmitter.
Has anybody had any luck with shielding and extra earthing to fix this problem? Any suggestions are greatly appreciated.
Kind Regards

I also faced the same problem. I was new with the cars at that time so i took it to the mechanic. All the best.
