Yeasu ft 857d noise problem
I just installed my ft857D in my ford 150. Noise is to loud from ignition to work mobile. Testing i find if i unhook Hustler antenna noise goes away.
What do I need to do to fix problem.
I am sure K0BG will come in and have more information; however, I am pretty sure his first question is going to be your vehicle bonding or your power set-up. I recently installed the FT-857D, I am still making tweaks to my set-up since without the noise blanker the ignition noise is too much, with the noise blanker there is zero ignition noise. Does your radio power directly off the battery? How is the radio attached to the vehicle? Did you bond your doors, exhaust system and hood? How is the antenna mounted? Where on the vehicle is it mounted?
Attached directly to the battery.
The antenna and radio are in the tool box.
No I have not done the items you mentioned, Help me with "noise blanker"
O.K. I can do better than that. The radio is inside the tool box mounted by use of the mounting bracket. The antenna is Magnet mounted on the lid with a two by two ft peace of iron mounted on the lid.
I had the ford all tuned up yesterday, no help.
Again with the antenna off, I have no noise.
As Steve suggested, you need to spend some time on my web site. The Bonding article is a good place to start, especially for a Ford pickup. Don't forget the hood, bed to frame, bed to cab, and the exhaust system.
Once you get that done, sans the mag mount! Excessive ground losses contribute to a lower SNR, hence more perceived RFI.
If the truck is older than 2003, you need to do the fuel pump ground mode as outlined in the TSB on same.
You said the transceiver's main body is mounted in the tool box. This would require the power cable being lengthened. How did you go about that?
I just returned from ur excelent site.
The installation was done by a radio shop and store here in the valley that does most professionals vehicles as well as all the tower work in the valley.
The power run is a new cable from the battery through the cab, out of the cab at the rear, they drilled a hole in the tool box and right to the radio which is mounted on the floor of the box.
The antenna is just above the radio.
The truck is a 2009 crew cab .
I will be spending the next two days doing the bonding.

I promise you bonding will help a lot. I had a mobile set-up before and I didn't use it much because of all the noise, I was ignorant and didn't know about how much bonding would help me and I sold the gear due to being busy with a full time job and tons of contract work but when I decided that I was in the car too much to not go mobile I decided to talk to my buddy who rovers during QSO Parties in Louisiana, Mississippi, Oklahoma and of course Texas and he showed me his set-up in his small car.
Get some 1/2" X 25' Tinned ground braid, make your ground straps as short as possible. I used existing bolts to do most of it and drilled in a few spots. I am using a very mediocre mobile set-up with the FT-857D and a Tarheel II (mounted on my trunk with a Diamond K-400) I am using the N2VZ auto tuner, my install was not exactly what K0BG "preaches" but driving home yesterday from work with the 56-inch whip attached I was getting 59+ signal reports from both the east and west coast at 7PM on 20 meters. First call to me was 9Y4D (I am sure I have worked him before though).
Here is a link to the 857D Manual -- http://mcars.us/Manuals/FT-857D_OP_Manual.pdf. If you hit the "F" key once and than use the "Selection" knob to the left of the "F" key and navigate to "M1" you will find the "NB" setting, select this and may help the noise some. Ideally you would limit the noise as much as you can without the Noise Blanker setting. I still have about S2 ignition noise, though part of this is that I did extend my power cable the old fashioned way by buying cable and soldering the extension on and I added about 4 ft to the cable that the radio comes with so that I could mount the radio where I wanted in the trunk.
Good luck with your install.
I had an FT-100 as well as an 857 in a 2001 F-150 Supercrew. The noise from these trucks is out of sight.
Lots and LOTS of bonding helps. I mean EVERYTHING. I perhaps had the greatest help with the exhaust bonding.
As an interesting aside, I switched from Fords to Toyota trucks last year. Bone stock, pretty much zero noise. Wierd.

I have a FT-857D installed in a 2011 Dodge Ram 2500 Diesel. No noise problems at all. Did not do a thing to bond anything. Only thing I had trouble with was the antenna. I ended converting to a DC ground which eliminated all the static build up. Quite as a mouse now.
