I have a Yaesu FT-891 in my truck. Have had lots of luck talking all over the country on it, and even overseas, but noise is a problem when the truck is running. There is ignition (spark plug) noise that is pretty loud. I can set the Noise Blanking function which eliminates the noise but makes the SSB voices sound like they are under water and drowning. So the choice seems to be between ignition noise or voice clarity.
Am I just stuck with this choice, or is there some magical setting on this (in my opinion) overly-complex rig that makes everything wonderful? I've played around with the settings on things like DNR, etc but to no real advantage.
Thanks...

Brady, the very first thing to do is check out www.k0bg.com.  There's a wealth of information about HF mobile installations and operating.  GL!

Hi,
Just wondering if you have figured out a solution. I have the same thing going on and have tried different options, including from the website that was posted before with no success.

Thanks,
Raul

Unfortunately the problem is with the truck, not the radio.  Of course bonding and grounding every thing on the truck is the start.  Often there are problems with the new fuel pumps.  Of course the electronic ignitions, AND there are a myriad of computers making noise and susceptible to RFI.  Have you tried contacting the manufactures rep? you can start with the dealer and ask for the regional rep, to see what literature the manufacture has.  Sometime they have retro kits that can be of some use.  The Champion spark plug company used to have a lot of literature on the subject.   Of course make sure your using resistor spark plug wires and resistor plugs.  Of course fully shielded spark plug wires and kits do exist.  Mostly seen in the Marine and Aeronautical industries.
