straxcla-
If you can try this. Power the radio from another source such as another vehicle. Move the complete radio over if you can and run the jeep. See if that clears it up. Or power it up from a spare battery sitting next to the radio.
Does your power lead cross over the top of the engine along the firewall?
Treat your power lines as an antenna. The closer they are to the noise source the more apt you are to hear it. Rule out possible causes one by one.

I brought this up to a retired Motorola engineer yesterday. He pointed out to me that there is an article in QRZ that talks about this very subject. Shows the danger of passing up the vehicles single point ground system especially in newer cars.
We used to install lightbars in cars that drew just under 50 amps when operational and we still never bypassed the vehicle single point ground to do so. We instead might add an extra ground between the battery and body per our engineer's instruction. Of course everything we do now consists of LEDs but the 110 watt radios still get installed.
Since my continued education actually comes from the manufacturers...
Anyways- ground systems I design these days need to survive lightning strikes and so far have.
Fred- Good luck! Hopefully you never burn up any of your equipment with your install methods, or the equipment of anyone else by your advice.

My point exactly we are NOT talking about newer cars the XJ's are at least 15 yrs. and older none of this applies. If you want to get technical about it many of the newer cars advise not to install 2 way radio equipment in them period or void the warranty.
BTW what is your call sign?
I have had a total of 5 different lighting hits here at my house all on my 150' tower and a 40' beam antenna on it and nothing has made into the house. I have never heard from anyone I know or from the radio system designer for the MO. SHP SW Division ever had in 26 yrs either of lighting hitting a patrol car. Must be a big issue in your area I guess.
Commercial radios are different in many areas one of them being just what you said they tell you exactly how to install what ever brand it may be. For good reason liability on their part and yours, I understand that and why. So lets just agree to disagree on this and leave it at that. I know that it works have used many times from radios to amps in mobiles have never had a single issue period in mine or many others I have done/helped install.
Have a great weekend!

I have 3 towers but that one is the tallest the others are 55' and 89' without masts. The 2 smaller ones are crank-up towers with fold over jigs allowing them to be lowered to the ground from the hinged base plate and winch.
I have a lot of antennas not just tower mounted ones either as I have lots of room here on the farm both transmit and receive only ones.

Right on. Must weird out the neighbors, lol. Hey, you could start your own ISP!
The smaller towers hinged at the bottom? One of the outfits my employer acquired rigged up a 60' that folded in the center. It's a good thing too, as nobody would climb it!

My closest neighbor is 3/4 of a mi. up the road. The 2 smaller crank-up towers crank down to 21' then fold over with a fixture attached to them to do so. Another antenna that looks somewhat like a tower is a multi-band 10-160m vertical that's 53' tall free standing.
This hobby goes along well with the XJ as I drive to the highest mountain tops I can then string up wire antennas. Then using a QRP (low power 5 watts) HF radio see how many contacts that I can work called DXing so far have worked 127 Countries QRP and 326 Countries using Hi Power 1500 w at home these are all phone (voice) contacts the hardest way.
Its a great hobby with a lot of awards if you want to chase them, I have for a number years and they cover several walls in my shack.
