Ahh.. I didn't realize my Yaesu and Icom's were so inadequate and deaf. Maybe those stations I hear that are not even registering on the meter are really not there. Maybe all the stations I have worked around the world are not really there. I guess I need to have my rigs worked on by your tech so I can here more? I still stand by my statement if you buy something and it needs to be fixed before you can use it is a waste of money but to each their own.

Old radio operators never die, they just fade into the ether.

Like I said to each his own. Regardless of how much noise a receiver has there will always be a point that an incoming signal will not register but be heard. The only real test is on a bench comparing its side by side to another rig with the same signal generator. I had the opportunity to play with an Icom 7000 and was not impressed with the factory receiver sensitivity. Fortunately after having the receiver reworked it's performance was comparable to all of my other radios.

.... again stuff that should show up in QC ....

Maybe it did. Is this luiton supposed to be a legit company? For pretty much all of them to have problems that aren't present in radios from other suppliers raises some red flags, it almost sounds like they get their stock by dumpster diving at the Qixiang plant.

question
i would like to ask here is is this -135DBm (0.0399Uv)@ 50 ohm at 10Db sinad or 12 db sinad or 10 dB S + N/N i see no where what that is referenced to
just you posting a number please explain the test procedure? .

i have yet to see any cb shop video show this in there super duper "tests "
(well expect two guys in Europe but their English is second language and unbearable however interesting videos with real merit and no sloppy tilting videos )

also has he taken into account noise in the test gear?
..his detected level maybe lower than this -135db figure

I relayed your question to him and he did not directly answer my question so I'm unable to accurately give you information you're looking for. He has several videos perhaps if you watch all of them you might be able to extrapolate the information

One of these days if time permits I might send one of these rigs to Sherwood engineering for analysis to give you the information you are looking for

Have you purchased from there? I would be leery of getting anything from that place. Here is their description:

That's a big walkie talkie..

This guy is an extra class that purchased from the original website that I posted and he seems happy with his purchase.

What? So because he is an "Extra" that makes it okay? Lot's of book smart Extra's out there.

Everybody has a different definition of what works for them. Some people think the ability to hear incoming signals .3uv in strength is perfectly acceptable.
My standards are much higher than most people so even if I bought an Icom or Yaesu, I would still need the receiver reworked to be able to hear .0399uv of incoming signal

Why? Its below the noise floor of every single HF band anywhere on planet earth. Even if you went into outer space it would be below the noise floor of every single HF band anywhere in our galaxy. There is simply no benefit at all to doing that and in fact it usually ends up being detrimental as it absolutely destroys the selectivity turning the radio into a splatterbox which sees the signal you're trying to listen to being swamped by the one on the adjacent channel or nearby frequency. It was common here in the UK in the 70s and 80s to do to CBs what you do and it just wrecked them and made them unusable.

Selectivity of a HF transceiver is infinitely more important than selectivity because we've already got to the point where even a cheap $50 CB can hear below the noise floor of anywhere in our galaxy However when it comes to selectivity, the ability to hear a weak signal with a strong one nearby, there is a world of difference between various radios. That is where you need to be concentrating your efforts on.

You may not want to do that when you see how poor the 2kHz dynamic range is compared to a stock one.

Remember if you have a radio that can normally hear to 0.3uV and you mod it to hear 0.03uV you're going to reduce the dynamic range in the line of around 10dB which is not a good thing.

I spoke to the guy at Sherwood engineering and he said he would run it through all his tests for a hundred bucks so whenever I get a chance I'll send him one of these rigs to analyze.

It doesn't make it okay it means he sent those people money and he got what he ordered. The whole point of mentioning this guy was to validate the legitimacy of the website offering that radio @ $180 to alleviate any concerns you might send your money and get ripped off because it's a Chinese company.
Somebody thought the website looked fishy.

You mean "Smelled Fishy"

I have no idea what that means
