HF FULL BAND Mod. v1 - Quansheng UV-K5 (Skyworks Si4732 chip, LYSIA)

LUSYA Si4732 HF FULL BAND modification of Quansheng UV-K5 and UV-K6 portable radio. We remove old Beken BK1080 FM chip, and replace it with a new Skyworks Si4732-A10 SDR chip, which is the essense of the LYSIA HF FULL BAND mod. After this mod your radio will have new SDR receiver when entering FM mode on your quansheng UV-k5 or UV-k6, new tuner has the following capabilities:
- Worldwide FM band support (64–108 MHz)
- Worldwide AM band support (520–1710 kHz)
- SW band support (2.3–26.1 MHz)
- LW band support (153–279 kHz)
- Excellent real-world performance with integrated AM/FM/SW/LW/RDS
- Integrated VCO
- Advanced AM/FM seek tuning
- Automatic frequency control (AFC)
- Automatic gain control (AGC)
- Digital FM stereo decoder
- Programmable de-emphasis
- Advanced Audio Processing
- Seven selectable AM channel filters
- AM/FM/SW/LW digital tuning
Now, you have to understand, even though you are modifying your quansheng, you are not modifying your quansheng -- because the radio part of it will remain the same, you are merely replacing a chip, which in your stock radio is responsible for FM broadcast radio reception. With this new mod, you are replacing that FM chip with an SDR chip which provides you with all the above mentioned functionality. However, it's only as good as the software... So hold your horses and be sure to watch part 3 of this video mini series, in part 3 we are going to be taking a look at the software. Part 2 is about changing your display and keyboard colors.
Part 2 -    • Change LCD Display & Keyboard Color -...  
Part 3 -    • Do you need FULL BAND HF LUSYA Si4732...
