I just stumbled on your channel. I’m new to this and I need a radio in this price range that can clearly listen to airband. I bought a UV-K5 but i’m disappointed with the sound quality I get when listening to airband…. ☹

The stock firmware is quite bad for airband. People might chime in and suggest other things beneath me because there’s a ton of options, but honestly the best all rounder for your use case is probably the IJV firmware for the radio. People love these radios primarily for the custom firmware, and it will help reception significantly.

Thanks for watching, as others have suggested, change the firmware to something like Egzumer for example. That should improve your airband reception. Hopefully this video may help you: kzread.info/dash/bejne/nY5ly5mSgJObmLQ.htmlsi=-sIDakILtYjTJI8y

It fails the 2nd condition of the vhf test in that the harmonic must must not exceed 25 µW below the fundamental frequency. My K5(99) flunks the test. At least on VHF.

I'm not sure that firmware is factory. I don't know that it's not, but mine has that firmware and when i go to NOAA (f+5) i get a band scope. I've also found some differences in the menu. I bought a second radio and it has different firmware and the functions are as the manual says. If you know where i can get the firmware you're testing I'd like it as i prefer that version.

@@m7frs272 yes I have 2 uv-k5 (99) . I got the first one and it has the firmware you tested. That one gives me a band scope thing thing when I press F+5 and menu 49 isn't "noaa-s" like the menu says. I've also noticed it has "frequency, channel, name and name+f" modes (menu 23). Menu options stop at 49 (reset) The second radio I literally got yesterday. It shows no version number on startup. And all functions appear to coincide with the manual. Menu 23 is limited to freq, channel or name. Menu 49 is NOAA_S. The menu has 51 total options with reset being 51. As I stated before I prefer the version you tested because I am a ham operator and in my area we have several repeaters that have different locations and different frequencies but the same call sign so displaying a name and frequency is really cool.

It's clearly the firmware that's allowing TX on air band. I never install firmware that allows this. It's all too easy to accidentally hit PTT. Extremely dangerous

People tend to forget that this is esencially a toy! So do not get your panties on a bunch here!!

All these radios transmit in FM, NOT AM, that makes them unusable on airband except for rx only. It would only tx qrm there. I can't figure out why so many people are interested in txing on airband. If anyone read this and answers that it's because they are certfied pilot, then you are required to use a proper airband certified radio. Don't be cheap with security equipment, people.

There is zero chance that the 99 can properly cover all of that frequency range. Bandpass and low-pass filters for all of those frequency ranges simply wouldn't fit in the HT. The laws of physics still apply, as well as the laws of economics. Those selling these radios will do whatever will sell radios. They are in China and they will never be arrested for selling dangerous radios. But the purchaser might.

It will receive, just not transmit on those

@Michigan_Tactical

You don't need filtering to receive. Sure you can make a better radio with filtering but it's not required. If you filter the transmitter so it forgets the unwanted harmonics you should be fine. However filters are nothing more than inductors and capacity which can be made on silicon. Not to mention DSP chips. I'm not saying these radios have filters or DSP but the size is not keeping it from having them. I have a Kenwood that's not much bigger than this radio that has DSP and all the filters. Yes it's slightly larger and more complex but it's also a 15 year older design. To be fair it was also $500+.

I hope that US customs blocks the import of this radio to the United States, this is a threat to aviation safety.

Most idiotic comment I've ever heard. There's dozens of radios out there that do airband, there's plenty of opportunities for people to cause harm in the world and this is what you're worried about? Don't you think someone's shooting at airplanes would be more of a threat to aviation safety than a radio? 😂 Should we block the import of automobiles too because some idiot decided to drive the wrong way down the highway?
