I doubt that the radio is actually TXing on a VHF frequency. When you do that sort of mod you can anter any frequency from 0-999MHz, but in most cases the actual TX freq is either a multiple or a fraction of the displayed freq, or else it does nothing.

If that guy's not blowing smoke, do like he says. Download the software and program your frequencies. If that solves your problem, go for it.

I guess is possible that the Chinese designed the electronics for both, intending to use the same innards on another radio that's marketed as VHF only. I don't know.

The VHF sensitivity is probably horrible. But whatever turns your crank...

Well, his works for some reason, mine doesn't...
Is it because he's using Windows 10, and I'm using 8?

For starters, you can't believe everything you see on the internet. There are plenty of Youtube videos that purport to prove that the earth is flat. Go read the Miklor article I linked. The Baofeng frequency expansion mods have the following problems:

1. RX sensitivity outside the designed freq range is terrible.

2. Out-of-range TX power is generally zero, or at best far less than what it is in the designed frequency range.

3. RX and TX freqs may not be the scame, because

4. the RX freq may be an image, fraction, or multiple of the nominal RX freq.

5. You have no guarantees that TX deviation or spectral purity meet any sort of standards, even the low ones used by Baofeng for transmitters operating as designed.

No, it's because the video is a bunch of hooey. The fact that the guy in the video was purportedly RXing a NOAA channel means nothing, because NOAA transmitters are hundreds of watts and RXing a nearby NOAA transmitter can pretty much be done with a crystal radio and a paper clip. You're not going to get VHF performance anything close to UHF performance from a modded UHF radio. Which is what most people's definition of "worked" would be.

You need to quit wasting your time trying to teach a pig to sing, and go get a radio that is actually designed to do what you want. A UV-5R is less than $25 if you're on a budget.

I suspect that we may well be being played here - all the questions asked can easily be Googled, yet the OP cannot google the facts on this radio, yet comes up with a very individual video supposedly proven g it can be done. two and two added together makes me very dubious somebody with claimed zero skill level can then attempt to convince us. It's a pocket money radio, and why would anyone even want to do it in the first place?

I actually did not know all the info. I received my uv-6. It works how I wanted it to work.
