Wouxun KG-818 VHF Teardown

20120626_112621

On the Hamradio Friedrichshafen I got myself a Wouxun KG-818 VHF (5W, 136-174.995 MHz). I plan to realize a small APRS transmitter for my car.

“The Wouxun…”

…whithout batteries. You have to remove the screws on the bottom left and right…

…as well as the nut around the antenna connector …

…to slide-wedge the whole assembly bottomwards-out. The dials will come off as well as some plastic thingy. Beware of the ribbon!

The two modules. On the left the processor/TRX-board, on the right, the LCD/speaker/kexs section with part of the case.

And once again the TRX/Chinagirl-module. Unfortunately the PCB is soldered to the RF-connector, which prevented me from further teardown, because I had no soldering iron at hand. Underneath the firmwaresticker it reads “M64X802”.

Great!” The TRX works even without its keys/speaker etc attached!

Well and that’s about it. I will mod this further so stay tuned.
