Also if you do a ctrl F5 it will clear your browser on that website and reload it. Maybe something wonky happened with some data. Not sure if that's universal, I know it works with Firefox

From time to time my browser displays something like you posted, but a quick refresh almost always results in the correct look. It usually happens when I have limited service and slow speeds. What does speedtest tell you? https://www.speedtest.net/

Works on Chrome for me also.

Ya, that's not happening. That's just causing trouble for myself. I'm sure if there were regulation violations Btech would be the first to know about it. I'll keep the box output under 50w and it's not going to bother anyone.

And it would make sense. You can have a 50 watt radio and put all kinds of doodads internally but as long as it all complies with part 95 and is 50 watts or less out the connector they probably don't care. Btech made a big deal out of it being an all in one unit along with being able to output close to 50 watts. You know people are always miffed when it says 50 and you only get 40 even though it likely won't even make a difference. But it's the thought that you paid for that output and it comes up short. As long as I can make it to my house I'm pretty alright with it. And I know that 25 watts from my house couldn't punch through the leaves and 50 watts does it in spades. So power can matter.

That would be a good thing to send to the fcc in response to their request for regulation simplification suggestions. I agree that it absolutely makes sense to look at the output of the box, but that’s not how the regulations are currently written.

yea, i just tried both and they are working.. I don't think it's my end. Two browsers dong the same??

I think you are correct, in that what the FCC care about is everything is in one chassis, and what transmit power is coming out of the chassis. Not necessarily the PA output power.

Manufacturer says the whole setup is Part 95 compliant. Pretty sure as long as it's designed and built as an all in one unit the output at the connector is what is limited to 50 watts.

I think that’s a problem on your end. Here’s how it looks in Chrome (and Safari) on my iPad:

This is what I have in Firefox. Looks normal

This is how the page is loading on Chrome and Brave this morning

I would also be weary of adjusting the power using the input voltage. That sounds dangerous for the long term survival of the circuits. That typically isn't the correct way to adjust a transmitter.

Thanks, Marc. The test report (not performed by the FCC) doesn’t even mention the existence of a duplexer. Although the test setup photos do show that the repeater output is what’s being tested, I wonder if the FCC even realized that there’s an internal duplexer.

I can find this stuff... but nothing I can open. Not sure where the actual letter and artifacts are. https://apps.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Sum&calledFromFrame=N&RequestTimeout=500&application_id=MjZkkijyA8IfBeMCZsYVMw%3D%3D&fcc_id=2AGNDGMRSRPT50

Steve, the FCC gave the repeater type certification based on the output of the duplexer because the duplexer is inside the chassis and considered and internal part of the radio... part of the design. https://fcc.report/FCC-ID/2AGNDGMRSRPT50 I am trying to find the official FCC cert, but that is the reference I found so far.

I’m not sure why you think regulations are different if the transmitter and duplexer are packed into an enclosure. The regulations very clearly state that the transmitter output power must be limited to 50 watts, not that the all-in-one box output power must be limited to 50 watts. You obviously understand the difference because you clearly distinguished between the transmitter output power and the duplexer output in your earlier post. But that was really the least of my concerns. The fact is that the transmitter is putting out 71 watts, which is harder on the circuits. That’s 40% higher power than designed.

This is compliant with part 95. Because it is sold as an all in one unit the output at the antenna connector is limited to 50 watts max. It has nothing to do with the internal components. But if you had this same transmitter and hooked it up to an external duplexer it would be against regulation. It's just like buying a 50 watt mobile radio. The output of the radio is 50 watts (or less) at the antenna output which falls within part 95. The duplexer needs to be inside the system and specifically designed to be an all in one system to comply. I think it's a 65 watt transmitter. I can't get it to go below 60 watts with the voltage on the power supply dialed down to 11.5 volts and I think it went up to about 71 when it was dialed up to 13.8v. I've never had it higher than that. This is what I bought, not something I made.

So far my wideband duplexer is working fine. Maybe the out of tune lets you throw more power at it. IDK. Looks like Btech will let me purchase another one of the newer Duplexers. It's the one I'm currently running and has been able to take the 70 watts in so far for about a year with no degradation. Not sure if they'll send it tuned to my spec or just send me another wideband. In which case I'll get it tuned. I have to go to their link they made specifically for me because the duplexers aren't in their catalog to sell.

The excessive RF power will take a toll on the circuitry of the transmitter as well as being non-compliant with GMRS regulations. I would suggest adjusting the RF output down to 50 watts at the transmitter output, before the input to the low side of the duplexer. Many times repeaters are run at reduced power levels to prevent early failure.

Whoa... that is the same issue Leo is having and on the same duplexer.... I may need to withdraw my endorsement.

This was the duplexer that came with the repeater originally. It was suppose to work with the transmitter power they had but obviously they were mistaken because they had to replace them. The duplexer they replaced it with seems to have the same power rating but has been working well since I replaced it. Most of the ratings I've seen on duplexers have a range rating and then a listed rating like this 40w-80w (50w). Before I toss it I'm going to pull it apart to see if there's any scorching of the internals. I don't expect anything to be wrong on the high (receive) side but on the low side there might be issues.

Everyone should review this old thread.

Hmmm... I can't help but wonder if it is an over-power issue with the duplexer. It's rated for 50w, I tested with about 45w after tuning it, and you're using 70w, which exceeds it's power rating by 30%. Exceeding the rating can cause overheating that can warp/melt internal parts and even cause internal arcing. That will definitely cause detuning and poor isolation, If I was a gambling man, I would say that it was off frequency when I got it, because parts were partially damaged inside (plating damaged, parts warped). I was keeping the power within spec, so I was able to tune and use it with the parts warped to the position that they were in. Now that it's being over-driven by 30% again, you are likely warping parts further, possibly causing plating to peel with excessive heat, which is causing arcing and detuning the duplexer.

Swapped the wideband duplexer back in and did my test loop. Pretty much back to normal. I think yesterdays test was slightly better but not by much. Had trouble in my usual spots. But I had trouble in a reliable spot too. Looks like for now this duplexer is staying put.
