WRXB215

Are you hearing the same traffic on both? If so this would indicate they are on a repeater and you would need to also be on a repeater channel with tones set to reach them. 

A node is simply a unique point that’s identifiable in some way.  Applied to GMRS it’s a unique location on a network of some kind.  The node identifier makes it possible to address the node individually. Because networking GMRS stations has been more strongly interpreted as prohibited by the FCC, nodes may no longer have usefulness.

I also wouldn’t give up just yet. More testing and more information is needed. 
What we know so far. 
* It works with another radio (as stated at 30’)
* The SWR is good
* You have the same results with both radios 
This leads me to believe something is going other than bad radios.
As it’s been suggested the possibility of tones with those that you are hearing or you are on simplex and hearing repeater traffic seem the most likely to me or you simply aren’t in range. A repeater can reach farther than you can in most cases. So you won’t necessarily be able to reach what you can hear. I doubt that both radios are bad. And the SWR readings suggest installation and cable are fine. 
So a few questions.
What channel are you on when you hear traffic? 
Do you hear them on both simplex channel and a repeater channel where you have not set tones?  
Have you tried getting someone you know to test at a further distance with your radios?
 

Don't second guess your purchase yet. The possible factors are:
* Others have tones set and you don't have the same tones set.
* Others are on a repeater and you're just talking on a simplex channel, also without tones.
* Nobody wants to talk to a random stranger yet.
* Poor signal propagation.
* 800 other things not related to a defective radio.
* Bad installation (severed coax for instance)
* 200 more things.
* Finally, maybe a defective radio.
 
But if you can hear the radio on another GMRS or FRS radio such as a cheap handheld, it's not probably defective or in need of updating. It's one of the other 1003 factors. You have a simple and reasonably good quality radio.

It’s possible that the OP is on one of the simplex channels. They share the receive frequencies with repeaters. Nobody on a repeater would ever hear him because he’s not transmitting with an offset.
Or, it’s possible that the OP is on the correct repeater frequency but transmitting with the wrong tone or possibly no tone. 
Or it’s possible that he is simply out of range. A repeater has a much greater range than a mobile and the OP already said it’s “super far distances.”

There are standard offsets. Many radios are programmed to automatically use them. Yaesu calls their Automatic Repeater Shift. 
For 2 meters the shift is 0.600 MHz.
For 70 cm it’s 5.000 MHz.
For 220 MHz it’s 1.25 MHz. 
For me anyway the question is whether the shift is positive or negative. I don’t know if there’s a convention that specifies that. But usually the information for a repeater will include either a plus or minus sign near the receiving frequency. 

What @SteveShannon said…
I don’t know that I would go so far as to use the word threaten but the downside has been debated ad nauseam. But since you asked, for one it has been pointed out there are limited channels available for GMRS repeater use. How will you know that the frequency is clear in the other area across county? You won’t.  
Amateur radio has more frequencies and coordination to avoid these issues.
I merely pointed out that a single linked repeater is the same issue but to a lesser degree as many linked repeaters. Ergo a slippery slope. Regardless of whether you agree or disagree with the decision about linked repeaters the issue and reasoning behind banning them is the same for two repeaters linked as it is for three or four or twenty.
If a family member of mine moves across country I’ll probably get their phone number. 

Repeaters are normally listed by their output frequency, you receive channel. Repeater channels set in your radio have the correct output channel (5 MHz higher) coded into the channel selected. Repeater input frequencies are all at 467 MHz while all the other channels are 462 MHz.

I don’t care about linked repeaters, but it’s almost like people refuse to use the search function and the same threads happen over and over. I wish people would do just a little homework before flogging the same dead horse.


Also, the latest iPhone software seems to conflict with the Tapatalk app. Whenever I quote a post it gets emoji-bombed.

Now get off my lawn!

And I thought it was just an old episode of the Andy Griffith show.

When I first got my license, Repeater Book listed a repeater 1.8 miles from my house. I was never able to connect to it and others could not hear me when using the same repeater.  I reached out to the owner only to find out they had to remove it by request of the property owner.  So yes, I did the whole "hey, I can start up a repeater" thought.  Then I got with the owner again and he let me know what all was involved in repeater ownership and I quickly changed my mind.

Ah, so THIS is what the CH. 15 bug was all about.

More like CNN’s credibility just exploded. I can see them being this stupid and air something like this.

yah.. i can...

An unfortunate reality of life.

Petn is used to set off C4. The expansion rate and heat are very high but the volume produced is much lower than the C4.

Oh Lord! I almost fell out of my chair on that one. 🤣

Could be that somebody found a stash of NOS, new old stock, radios and sold them cheap. So it could still be the real product. 
Stuff like this shows up frequently on the Internet for sale. The two dPMR Icom radios I just purchased were exactly that, NOS.

So if these are really clone rip-offs of Icom's design, as was suggested, have these shown up anywhere else in the world?
Last possibility is the Israelis had a stock of these in a warehouse they were never going to use and heard that Hezbollah was in the market for buying cheap two-way radios.  So, they doctored them up a bit and sold them through a middle man to hide the source. 

They ticket you and then you have to pay or go to court.  Either way they screwed with your life.  Go ahead and tell the cop that he can't legally give you this ticket and all he'll say is tell it to the judge.
And your life is still screwed with and now you have a cop that doesn't like you.

The simplest solution is to purchase a product like the Retevis RT-97s or the very similar Midland repeater.  The Retevis is even available in an all-in-one kit with antenna and cable.  you can buy it, put the antenna up, screw the cable to the antenna and the radio, connect power, and be up and operating within a very short time.
Messing around with two radios connected as a repeater can be done and is an inexpensive way to get more power, but requires more support, plus the KG1000g has been shown to have issues with desense when used that way unless you find a way to isolate the two radios from each other. Notarubicon has a series of videos showing him setting up a repeater using the KG1000g.  
If you do decide to go the separate radio route my suggestion would be to go to a nearby ham radio club and ask for assistance.  Someone there will have the experience and the willingness to help you.  

My family isn't THAT important 😆
