I have thought about a fused link between the ground post on my bulkhead and ground rod.. Either way, I do always disconnect everything when a lightening storm approaches. Everything els will help with near strikes and for static discharges.

I might have over did things in my setup. The service ground is in between my mast and where the coax cables enter the house. I put a ground rod at the base of the mast and another right below where the coax bulk head is. I tied both grounds rods to my service ground with 6 gauge wire. All of the ADU's are grounded to the rod at the entry point. I made my own bulkhead using metal plates and long bulkheads (to get through the wall) along with a piece of 1/4" 20 all thread for grounding. I ran grounds from all my radios and my tuner to the all thread which is also connected to the ground rod just outside.

I hae no experience with the CA-GMRS so I can't comment on it. I do have several Comet antennas and I have been very happy with all of them. I have a GP-9 and CA-712EFC base antennas along with a SBB-1 and 2x4SR mobile antennas. I don't think you will go wrong with the CA-GMRS if it is anything like the Comet antennas I have.

My preference for an OS is Mac while I don't mind using Linux. I have not cared for Windows since they released Windows 8.1. One of the issues I have with Widows is the fact that the more RAM you add, the more Windows wants to take, which does affect how much RAM you can give multiple virtual machines. Needless to say I am not a fan of Microsoft or Windows OS. Windows 2000 Pro, XP Pro, and 7 Pro were good operating systems. Windows ME, Vista and 8 were total wrecks. Windows 10 isn't bad. But Windows 11 is convoluted for system administrators which how it hides the admin menus. I wouldn't have a Windows (PC or virtual machine) in my house if I didn't need one for certain radio and model train programs. I actually have a degree in network administration and went through the Microsoft MCSE courses, Linux admin courses and Cisco CCNA courses. While MacOS is not perfect it is overall easier to deal with compared to Windows 11 and Linux. And since I am stuck with having to have a Windows PC, then I will just run Windows native programs on it versus running them in a virtual machine. Wine and other emulators don't always work well.

The reeve.com PDF file must be a good reference considering three of us have posted links to it. And nothing will protect your setup from a direct lightening strike. Read through the references we provided and go with what works best for you and still meets NEC. PS: definitely unplug everything before hand if you know a lightening storm is heading your way.

Yes there are many opinions on this subject. Your best bet is to follow NEC when it comes to grounding your antennas, coax, and radios. Here are a couple of other links that will be helpful for you. https://reeve.com/Documents/Articles Papers/Reeve_AntennaSystemGroundingRequirements.pdf https://www.arrl.org/grounding GMRS and amateur radio antennas, coax and equipment require the same grounding techniques.

Using a VM or Remote Desktop is always an option. But I would rather have Mac native software when possible. It is just easier to deal with. I have never had much luck with Wine or other emulators on Linux or Mac. The Apple ecosystem has spoiled me a bit since it is so much easier to deal with when you have multiple Mac's and Apple iPads, etc. I am currently running Mac, Linux and Windows on separate computers. The Linux computer basically runs just one program for me which is HamClock. The Windows 11 computer is currently running WSJT-X, TQSL, and Grid Tracker for running digital modes, along with my Windows only CPS programs. Anyway, I'm glad that RT Systems has come through for the AT-779/DB20G and it is working well for everyone.

I'm so glad that I set my coffee down before reading that. Coffee is hard to clean up from keyboards and monitors. And yes the RT systems is definitely worth it. While the Icom CPS is not bad, RT Systems is definitely easier to use. I am still waiting on a reply from RT systems about porting their Wouxun software over to MacOS. They did reply asking what radios but I have not heard anything else from them yet.

I have to agree with what others have said. The only way to know is to try. I would definitely check the antenna with an analyzer before and after to see what the differences are.

It looks like it will transmit at around 8 watts on the 2m and 70cm bands only. It puts out an average of 5 watts on the 1.25m (220MHz) band, and around 5-6 watts on GMRS. This is quite normal for any dual, tri, or quad band radio. @OffRoaderX got the following results with the KG-935H he tested in his video 2m - 8.45 watts 1.25m - 4.87 watts 70cm - 8.224 watts GMRS - 5,73 watts Go to the 17:43 time mark for the output results. https://www.youtube.com/watch?v=O1LphnxN15o I don't have a KG-935H to test but I did test my KG-Q10H.Here are the output watts on the different bands on my KG-Q10H 2m - 4.43 watts 70cm - 5.9 watts 1.25m - 2 watts 6m - 1.5 watts GMRS - 3.5 watts MURS - 1.5 watts The KG-Q10H and KG-935H will both use the same unlock code. Don't bother trying the unlocked code with the KG-935G or KG-Q10G models since it will NOT work.

Since this is in your vehicle, I have to ask. Does it only happen when the truck is running? The reason I ask is that you stated that you do not have an issue when the radio is connected to a power supplying your house. This makes me think that you are getting interference from your truck.

Give it time and RT Systems might come out with a Mac version. I run the RT Systems software for my Icom radios on my Mac. I would get the RT Systems software for my Wouxun radios if they had a Mac version. Edit: I just sent an email to RT Systems asking about Mac versions for the Wouxun radios and will update when I hear back from them.

It depends on the brand of radio and on the antenna used. I have tried the Nagoya 771G and the Abbree version on my Baofeng UV-5R GMRS radios and on my Wouxun KG-935G. I saw an improvement with the 771G and the UV-5R GMRS radios compared to the stock antennas. It was just the opposite with the KG-935G, the stock antenna did better. I have tried the Nagoya 771 dual band antenna on the following radios: Baofeng GT-5R, Explorer QRZ-1 (TYT UV-88), and Icom IC-T10. GT-5R - 771 did better QRZ-1 - 771 no difference between the 771 and stock antenna IC-T10 - stock antenna did better. Your results may vary from mine.

Go with what works for you. That being said, it sounds like there are some issues with the DB-20G that need to be addressed. The radios should work fine when set to wide band without any interference. And it is obvious that there is a problem with the radio since people are having issues when transmitting on wide band. And the seller and/or manufacturer will not know about the issues if people don't let them know.

And you also don't have to worry about what operating system you are using either. The RT Systems cables have worked with Linux, Mac and Windows 10/11 without issue for me.

RT Systems has software for most, but not all, of the Wouxun radios. I know some do not like to pay for programming software but the $35 cost of the RT Systems is reasonable and is veery easy to use.

Talk about resurrecting a zombie thread

I am doing my best to resist getting the new KG-935H. What is helping me resist is keeping my KG-Q10H right in front of me as a reminder that I don't need the 935H. Wish me luck

Most vehicles with the Auto Stop Start systems all use sealed and spill proof AGM batteries. AGM batteries are a whole lot safer than a standard flooded lead acid battery. And the Auto Stop Start system is standard on most newer vehicles now days. I do agree that you should always be cautious when working around any type of battery.

That use to be the best way to hook up radios but that doesn't work very well with modern vehicles with all of the computers and battery management system onboard. I know battery chargers/maintainers are different than two way radios, but the manufacturers don't even want you to connect a charger to the negative terminal of the battery on newer vehicles. They will state to use a good chassis ground so you don't take any chances of messing up the battery monitoring system or computer modules.

That can't be stated enough with newer vehicles AKA computers on wheels.

Nothing would happen unless a person was an idiot about it and caused problems. I mentioned that is against FCC regulations just so people know and don't take a chance getting in trouble. It's no different that how you mentioned it in your video about the new KG-935H. No different than the other day. I was talking to someone while I was on our 2m repeater and it took a minute to realize he was on our GMRS repeater. I quickly let him know what was going on and we laughed about it. A few of us have done the same thing with our 2m and 70cm repeaters. One will be on the 2m repeater while the other is on the 70cm repeater. Again we correct each other and laugh about it.

The 935H also has cross band repeat. The Q10H is quad band and superheterodyne while the 935H is tri band and SOC. I have not noticed much of a difference between the Q10H or Q10G and the 935G as far as TX and RX. Both work well. While you can cross band repeat from GMRS to 2m, I highly recommend that you never do that except for absolute life or death emergencies. You will be wrong cross band from GMRS to 2m even if you have both licenses. FCC regulations do not allow cross band between different services.

That's hard to say since I had the 935G for a while before getting the Q10H. The Q10H has the advantage of being quad band versus the 935H being tri band. Both can be unlocked for use on MURS and GMRS. The nice thing about the 935G is that I can give to a family member and not worry about them accidentally transmitting on the amateur bands. Remember that the 935G and Q10G are GMRS only radios and can't be unlocked. Yes I tried and the unlock password will not work on the GMRS only radios.

I have to agree. I like my Q10H and 935G. I would seriously consider getting the 935H if I didn't already have the Q10H.
