エアバンドレシーバーキットの組み立て、改造を手掛けます Assemble and remodel Chinese airband receiver kit

I posted R909-DSP video on YOUTUBE YOUTUBEに紹介ビデオアップロードしました





As I finished to debug for Arduino based Si4732+Si5351a+OLED airband radio, I edited the introduction video.

I installed the radio electronics into the aluminum mold case as looking like as ATS20.

There are PANEL PCB and RF PCB. The sensitivity is not enough (-85dBm) and I added LNA module on radio. So I would like to reedit the RF PCB pattern.
