Quansheng UV K5(8) - 999 Channels Hardware mod - EPROM replacement 

Thank you! These components are so small and when I use just my eyes it looks good, but after I see it on video I usually have to redo it :) Definitely I will need to inspect soldering work every time not hoping that everything is fine.

I like the radio. It sits in my hand well (I wanted to get Yaesu FT-60, but that is too wide for my hand). However I didn't use it with stock firmware. Big advantage is firmware mods and even hardware mods. I installed IJV 3.x right after I got the radio. IJV user interface is convenient. Easy to change modes. I use Chirp to program repeaters. In my area we have many repeaters on top of mountains, so using this radio and homemade vertical dipole I can easily reach repeaters. However I mostly listen. I got longer antenna for the radio and it works well. Battery lasts several days on scanning. I don't have much radios to compare it to, but currently it's the radio I use for VHF and happy with. Receiver is not as good as Icom IC-7100 I compared it to, but that Icom is from very different category and costs 50 times more. I had baofeng UV-5 and UV-82, and I didn't like them and almost didn't use them. Compared to baofeng it has cleaner signal (better harmonics rejection) more convenient display as well. It's not perfect radio, not waterproof, receiver can be overloaded by strong signals (like most of other handheld radios), but it's very capable radio for the price. I do have 2m bandpass filter and sometimes use it. It reduces receiving noise level when radio connected to external antenna. As I'm not going to spend hundreds of dollars on handheld radio currently UV-k5(8) is the radio of my choice for price range under $100 and for experiments.

@@yurishbox Where did you find the drivers for chirp with the ijv v3? when i try, it says firmware not supported. I will prob try egzumer because it has a spectrum feature.

@@ostar-en7ec If you download IJV firmware from their official site there is a .py file in the archive with IJV firmware. For 3.13 it's uvk5_IJV_vX3_36.py When you run Chirp go to Help/Developer Mode. Than restart chirp and go to File/Load Module and select that py file. After that when you open Radio/Download from radio select that IJV in Model field. Official IJV site is www.universirius.com/en_gb/preppers/quansheng-uv-k5-manuale-del-firmware-ijv_v3/

Yes, I wanted 999 channels to spread them on 15 scan lists and switch between scan lists when travel. Like a separate list for repeaters per state I visit.
