Disassembly of Baofeng UV-5R

I was able to see if I could control the frequency of the UV-5R.
How? Open the Cover and look!




if you want to completely disassembled the UV-5R, you will have to find the hidden screw under the LCD.




The MCU ( MB95F013K) shown in the picture below is the main controller of the transceiver.



and The RF Controller (Left chip marked - 1846 - RDA1846) shwon in the picture covers VHF and UHF.

VHF :  134~174MHz, 200~260MHz (but, only 134~174 VHF present on UV-5R)
UHF : 400~520MHz




RDA1846 has as 24Mhz oscillator connected,


if you replaced other frequency osclillator, perhap the frequency ramge pf use of the radio will change.

Components such as filters due to frequency changes will have to change together.

Release CEC Firmware v1.200 for uBITX All version(include V2, V3, V4, V5)

Release CEC Firmware v1.200 for uBITX All Version (include v2, v3, v4, v5) I did the firmware work for v5 when uBITX V5 was released, but I release it now. I received the feedback from a thankful beta tester and tested it myself by converting my uBITX v3 to v5 but I was not sure. I ordered the uBITX V5 and delivered the correct uBITX V5, so I made a little more fine-tuning. If you use V2, V3, V4, you do not need to update this firmware.
