For noise reduction? re exhaust
I worked on bonding my 2008 F150 over the weekend, it has terrible noise on 20 and 80m. Bonded the hood, front doors, cab, and bed, and one strap on the exhaust. Ran out of flat braid so I'll order more tomorrow to finish the job.
I did have S9 Plus noise on 20m but what little I did, which was about 30 minutes of work cut it back to S6-4 with the noise blanker taking it much further down. On 80m the noise blanker completely kills the noise after bonding.
I am hoping that after I add a few straps to the exhaust up near the engine it will quiet things down a bit more. I need to add a couple more straps to the cab to frame and cab to bed as well.
F150s are terrible.
Engine is a 4.6l Very reliable but horrible on HF and VHF for noise.
