Quansheng UV-K5 Spectrum Analyzer on the EGZUMER Firmware

[@billrodgers5532]

During scanning, Any received signal can be captured by pressing the PTT button. Another screen opens up and displays the signal.

[@purehillmanimp]

Thanks! That’s what I came to the video hoping to find. I also discovered that pressing exit returns to the spectrum.

Greetings from Brazil ! I flashed version 0.22 successfully! Thank you very much, friend! Thank you EGZumer for the excellent work!

[@oljobo]

Brilliant! I got so many questions answered! Thanks 👍😊

[@Pedro8k]

This one funtion in this firmware is worth buying the radio for remember its low price cannot see that in any other cheap radio

[@nine7295]

I think it's more accurately referred to as a spectrum scan or spectrum sweep display. Spectrum analyzer is a different animal.

[@jonlawrence]

I don’t disagree with you, but that is what the developer calls it.

[@lokthalas7540]

Any good antenna for the AirBand plz?

[@aaronhope8366]

Well that's very interesting indeed.

[@gerdbaier9437]

Hi, hope you can help me. I bought a Quansheng UV K5 from Ali Express. Device works good, but in the Frequency Range from 350-399.975Mhz it is not possible to send. When i push the Send Button in this range, the Display shows "TX-Disable". I thought a firmware update on egzumer would solve the problem, but I still can't transmit in this frequency band. What could I do to fix this?

[@jonlawrence]

I made a video just for you to answer that question. kzbin.info/www/bejne/moG4ZGqDrrF0oc0

@@jonlawrence Thanks !

[@orlandoalarcon4158]

Falta la función borrar cuando detecta una señal sin audio , pues hay señales que solo hacen ruido y no como eliminarlos

[@jonlawrence]

I would say you should report that to EGZUMER, perhaps he can fix it.

[@SkyWaveSDR]

It's also compatible with UV-K6, you may want to include it in the title. I'm using this FW with the K6 currently.

[@jonlawrence]

You are right, it is my understanding that the only difference between the K5 and the K6 is cosmetic, it is the same radio internals.

[@FanchBreizh]

can it give the power of the signal for FM radio 88 to 108MHz?

[@Serdnazonum]

Hey I love Matt's of road!, wonder how did you got that hoodie! ;)

[@juanjoivars3254]

I have been twideling detailed spectrum frecuency mode, the screen that appears when you press PTT in the spectrum analyzer and I don't understand what are the IF values: 1, 10923, 21845, 32767, 43689, 54611, 65533 I think it's related with the intermediate shifted frequency signal manipulation process, but what are these values? Based on the last value: 65533, it seems to be a 16bit value.

[@jonlawrence]

Not sure I know either

[@charleysevers]

on the spectrum analyzer - how can you move to the spiked part on the spectrum ? how can you scan a band ?

[@jonlawrence]

Press 5 while in the analyzer and it will allow you to set the center frequency. Instructions on how to use this mode are available here: github.com/egzumer/uv-k5-firmware-custom/wiki/Spectrum-analyzer

[@shadowpapito]

Thank you ...

[@lisocampos8080]

Is it wise to post your name and address on the internet/airwaves?

[@jonlawrence]

Yes, super wise

[@screennamie]

Can you transmit from the spectrum analyzer or only rx?

[@jonlawrence]

You can switch to TX from the analyzer

[@costy91395139561]

How?

[@Lansolot]

incredible! does this work on uk5 (8) too?

[@jonlawrence]

If you mean UV-K5(8), then yes, it has the same internals as the UV-K5 and UV-K6.

[@Lansolot]

@@jonlawrence ty! Just bought one

[@Richardlc]

Nice firmware

[@optscep]

Is this the best firmware?

[@jonlawrence]

A lot of people like EGZumer or IJV, probably more about personal preference

[@ragheadand420roll]

Thanks

boafeng much better, had this one had to send it back, software is kinda buggy, reception not as good as boafeng. complicated software design. i do not understand why this radio is such a hype.

[@jonlawrence]

The biggest reason for me is the ability to customize it with whatever firmware I want. To my knowledge not very many radios have this capability.

[@trexostrexantiros742]

Because you know nothing about ham radio equipment and because your knowledge is limited.

[@germanjohn5626]

I did not found this mode to be more than a useless toy. It doesn't really analyze anything just gives one a very course indication that there is something. For ~20 bucks more I can get a TinySA that will give me a lot more info about the signal,frequency and range scanned. Even the worse chinese clone functions better than this.

[@jonlawrence]

Perhaps you are right, but there are a lot of people with this radio already that might find it interesting. Sorry to waste your time.

[@tsp2jxd]

I find the feature very useful!!! Thank you for sharing.

[@nathanwaller7242]

You can set up the steps so it's very sensitive and your lack of understanding shows. very grateful for this feature and find it very useful.

[@r00kiet80]

No shit you can get something better for more then double the price lol

[@TheCablebill]

It's a handy little spectrum sweep that just happens to be in a rugged cheap little HT. Free, with nothing else needed to carry around. I love it. Useful? I'll find out.
