For not much more money, you could get a 40-watt Motorola MTR2000 UHF repeater which will have decent sensitivity and excellent selectivity. I use MTR2000 and Quantars for my ham repeaters, which would also work great for GMRS. Also the Motorola GR1225 repeaters can be had for very cheap, and will work well for GMRS service. You can't go wrong there.

I am a year late to this video, had similar issues for a while, I moved my antenna and it improved my situation. You may have noise in the area, or when it's repeating you may have an issue with grounding. I gave up, got a retevis rt97s , burned it out then got a pair of motos..had the same issue so I took my motos on a trip away from my home and discovered they worked without issue. The weather changed, got warmer and some of my noise went away. I am shooting in the dark, but outside of replacing everything, recently I had issues until I replaced my tone pairs. Again, I have noise, I also had issues with the current tones.

Ive Tried 2 of the kg uv980 As repeaters with the same results. Two seperate antennas about 27 ft.apart. 1/4 mile Distance at best. These radios are Junk as Repeaters. No front end Recievers. Buy a real quality repeater on ebay Or some place reputable. It will make a difference. Thanks for the info. Best Of luck with Your project.

Thanks for the video it was very useful. You saved me time and money.

Thanks for sharing. Sounds like you really tried to make it work out.

Dang I was just looking at getting two of these for a repeater build as well, especially since they are 50 watts and certified for GMRS use. This is discouraging news

So as far as distance how many miles can you receive in repeater mode. And how many miles in non repeater mode.. thanks

Wow hope I have better luck i just bought a similar set up , just haven't put it together yet.

you have to keep the radios separated as far apart as you can get them

Wouxun tech support said what about this?

I just got two units in for the same purpose. I'll test them out and see if my results are similar

I have same issue with the KG1000.. repeater mode receive side. the Transmit range is over 10 miles.. and the receive range is about 1.5 miles.

Hello, thank you for the great information. I have a question that might seem silly or stupid but I had the exact same problem you had and the one thing that did the trick for me was reversing the cables that go to the duplexer. I have the transmit unit on the high side and the receiver on the low side. Before doing this I could only get like a block away before I lost reach. After switching the cables I have tested at 15+ miles on a baofeng handheld and only because I haven’t had time to test further out but I plan to do.

Unacceptable as Hell! I knew it! this is WHY I wait before buying OR wait for 2nd or 3rd Gen. The quality of ALL products and R&D and Beta testing have gone massively down since the 1980's. In the 80's they released practically perfect products. Man this saddens me greatly. Someone in the comments below complained as standalone the KG1000G locks up after a few minutes.

Same issue with a pair of KG-UV980Ps. 10 mile radius on simplex, about 0.5 mile radius when in repeater mode. This isn't going to work. What business repeater did you end up with? I'm looking into the Motorola MTR2000 100W. Seems to be a solid move with more power.

What Pre-Amp did you use? I am using ICOM IC-FR4000 machines for my repeaters. Antennas are L-Com HG459U, and a pre-amp from ARR.

Using 2 mobiles with a surecom duplexer controller works a lot better than linking them together in relay mode. But, by the time you buy 2 mobiles, power supply, a surecom duplexer controller, a duplexer, antenna, cables and wiring, plus your time spent, it's not worth it. If money is tight build a simplex repeater, otherwise buy a factory built duplex repeater. To cut down on cost find other gmrs users in your area, a lot of the time you can find 4-5 people willing to split the cost with you.

were you having desense issues where the transmitter of your repeater would key up and hurt the sensitivity of the receiver? I wouldn't trust these radios as a repeater anyways seeing they don't have a real receiver front end. And if you were going to use these radios as a repeater, I would either use a bandpass / reject duplexer or run lower power if using only a notch duplexer.

Has this been fixed with the NEWER KG1000G Plus??

I wonder what the range would be if I installed the kg-1000g into my pickup truck? Just got my gmrs license and just learning how to navigate. A lot of the things you said in the video are way over my head. Maybe you could point my in the right direction. Thankyou!

I know you tested a lot of things while doing this but as some suggested placing the radios apart from each other, did you try isolating the receiver from the transmitter via shielding or other means? If so can you list what you tried?

Bottom line, this is for a farm. The receiver in these radios when put in repeater mode are desensitized via the firmware. These radios are great to throw in your truck, but don’t think you’re gonna setup a repeater.

Thanks 🙏

is this the same for the newer plus versions as well?

So I got mine set up and having troubles , it won't transmit an audible sound. The transmit radio shows its transmitting but I don't hear anything from my HTs Also, at times after I talk on my HT to the repeater a d release the PTT button the repeater doesn't release and will keep repeating long after the transmission is ended. Any help appreciated -WRQC955

by the way, what kind of coax are you running?

How many feet of coax are you using??

I also bought two KG1000g radios one for my truck and one for my wife’s truck. I have noticed that after about 30 minutes the radios will lock up. They won’t transmit or receive or respond to any buttons on the speaker mic nor the head unit except for the power button on the head unit. You can recycle power and they will work fine for about another 30 minutes. Also I configured them to auto power off at 30 minutes. But once they lock up they don’t auto power off and will drain the battery in my truck. Any thoughts or have you experienced any of this? One last thing when receiving audio the audio will play for 4 seconds then cut out for about a second and then back on. They do this all the time and it’s very annoying when trying to have a conversation. It doesn’t matter what freq I am on or what band I am listening too either.

Can you give me more specific info on the coax please. Setting up my GMRS repeater.

Sounds like line of sight issues

The coax you’re talking about is the Italian coax ?

The this apply to all Wouxun KG-UV980P...? I am keen on buying two radios link am them. and build a 6 metre repeater.

I'd be super curious to hear if anyone has experienced anything similar on KG-UN980P

Nothing beats commercial when it comes to serious communication. Of course, you gone to have slack from individuals. Oh, that's not FCC typed accepted, you can't do that. Actually, you do what makes sense as long as you use the repeater as intended. Who cares?? It's like you setting up network and profiting from the system.

What range were you getting bc I'm planning on doing same thing Already bought equipment

Get yourself a Bridgecom GMRS repeater with built-in duplexer.

And the money pit continues.

Incredible waste of time and money. Full package Motorola systems on eBay for less than 1k all day

Move your cellphone away from your mic please
