you haven't explained anything in regards to the difference in placing ground to battery or chassis. Nada.. Tu-Tu. But i bet if you google its you'll find Motorola recommends grounding to chassis to save on material cost since they offen install the transceiver brick the trunks or backends of vehicles..
you do what you want,, But i'll tell you, your reason is 100% incorrect. Like i say, until you can prove to me from an engineering stand point grounding to a separate location is beneficial over grounding at the battery location your point is mute.. And dont confuse from connecting sources with power vs sources that draw power.. Completely different scenarios!!
There is a huge difference connecting a battery charger to a battery and connecting a source that draws power.. The latter will have no effects on the vehicles electrical system or its can buss system regardless where you place its ground.. It's always best to place grounds at the common location with other vehicle grounds.
There is no proven reason to ground separate to the vehicle chassis vs. the battery ground. In fact, there are more reasons not to ground to chassis then to the battery ground. Especially in vehicles built today having various chassis insulators, protective sheet metal coatings and metals with poor conductivity. If you can provide an reasonably explanation from an engineering standpoint, you might have my ear..
Try installing a braided ground strap from your hood to the opposite chassis and even across your exhaust and the chassis. Use an inline noise filter, Kenwood and Icom make a nifty one and use ferret beads.. Make power connections directly to the battery with quality 10GA wire. both ground and positive. That should eliminate most all your noise problems. Ram Trucks are notorious for generating noise in Ham radios... I've applied everything i mentioned to friends with Rams and problems eliminated.
certainly a lot of questions on voter integrity.. Last i checked, AZ leads with the most arrest for voter fraud and holds title for the most allegtions against fair elections.. Yup, getting ready to leave Calif myself, and AZ was the last place to consider..
Pretty easy to mitigate if two radios have that problem. I had it with my KG1000 repeater and a simple piece if sheet metal cured it. I have two Maxon’s in an ammo Box serving as a portable repeater and no issues with desenses without adding shielding. I think if you use decent radio’s, you’ll be o.k.
Amazon and Ebay are loaded with HT repeater controllers, just make sure you get a controller that supports the two specific HT's you plan to use. Most Baufangs will be supported.. And you'll need a low power duplexer.. Probably not worth the trouble with HT's though. The same concept will work with most mobil transceivers and would be a better way to go. Some mobil transceivers, like the Wouxun KG-1000 and Maxon's won't need a controller as it is part of the radio but rather a jumper cable between the two.
Not only digital data but a growing trend of people using DMR on GMRS.. I've noticed the 4 Wheelers like to use digital down here in the desert.. GMRS has turned into a hotbed of 'lets do whatever we want'
I'd go with a home brew J-pole or Ed Fong's J-Pole.. I actually have both that i have used for my portable repeater and both are pretty impressive antennas.. Ed Fong is a bit more 'eye' pleasing.
I dont think this forum has a quota.. After all, there are a small handful that basically live here, its there life.. So you shouldn't have any problems.... Post away
GMRS is cast in its own stone... There will not be any changes now or almost ever.....1 & 2 = 61 days and counting down.. In the meantime,, we have a Lame Duck
