Yaesu FT-891/ATAS-120a in a 3rd Gen

So how much of the fuel pump noise did you get rid on 20m? I don't have any noise on UHF just on HF.

 

I would say about "half". Without bonding, a 20m signal at +20 or better would be completely wiped out with the engine on. I can hear a +20 signal and about a 2 after bonding. Still completely unusable. Everything north of 20m is fine with engine on, driving down the road, etc.

 

Whoa you totally one-upped with the copper bolt washer idea. Those are amazing, how can I do that?

 

1/2" water pipe for the braid ends. It fits .75" braid perfectly. If you don't want to cut off you're own pipe, just buy the copper 1/2" couplers at Home Depot. Smash them onto the ends of the braid using your trailer ball as and anvil. Trim the excess flush with scissors. Drill a .25" hole and attach with stainless hardware.

 

Genius is clearly noted when someone says Why didn't I think of that?

Nice, clean bonding!

 

Love that AH4/whip setup! Ran that with an IC-706MkIIG in a Jeep I used to have. Wish I’d never sold it (the rig, antenna system, or Jeep, actually).

 

I had a thread about the PWM noise the fuel pump and the pump ECM spews with some spectrum analyzer videos. I gave up because the fix would more than likely void warranty and Im waiting to see if the fuel pump recall extends to the '16's at all before I tear into this down the road.

LOL , nevermind, I see you posted on my thread. For some reason , I never got the alerts and this is the first time im seeing it .....

Ok, Im going back into my corner now .....

 

I found this to be a bit more fun operating anyway. Did some OSV this week in VA

absolute Zero noise floor

 

I know what you mean...

 

Here is a link to my 2 part install I did with a ft-891/Icom 5100a/atas120a. I was able to handle engine noise with noise blanker on level 1. PT1: https://www.youtube.com/watch?v=NaSP5KgDhDU&t=10s PT2: https://www.youtube.com/watch?v=QR9gyBICiE0&t=1s . Sadly, this tacoma died in a 4ft mud pit shortly after I had the build pretty much done. :/ I'm now working on a second 2020 TRDOR. I may install the radios a little differently this time, I'm not sure yet.

 

How did this setup work for you? I need something for a quick POTA activation and I have a spare FT-891 not used right now.
