Baofeng UV9R (Waterproof) Programming with Arduino

    This is simple method to program UV9R Plus or similar waterproof radio's belonging to Baofeng family of radio's. Here we will be utilizing the USB to Serial interface of Arduino Uno to perform the required programming. Also we will be describing method to prepare radio interface adapter using easy to procure items like Common PCB , berg pins and jumper cables.

    UV9R Plus is IP57 dust and water proof resistant radio which requires special water proof interface cables to program the channels and update radio related settings. Today we will go through the programming part of this radio. The inspiration to use Arduino to program the radio comes from here. We will be focusing more on building an interface adapter to avoid direct soldering in radio interface contact points.

 

Baofeng UV5R Programming with Arduino

     This is simple method to program UV5R or similar radio's belonging to Baofeng family of radio's. Here we will be utilizing the USB to Serial interface of Arduino Uno to perform the required programming. Also we will be describing method to prepare radio interface cable using simple audio jack and few wire.

PTT MIC from Junk

    Recycling junk materials to useful things can also be done by giving new meaning to them. Here presenting my PTT MIC for my home brew HF Transceiver. This is not a universal compatible but i can assure its compatible to all equipment interfaces in my shack. Its harvested it mostly from junk materials and i doubt about the reproducibility of this specimen.

Rig- PC Interface for Digital Modes

      Hi, Described here is a circuit setup for interfacing PC soundcard with radio equipment for transferring digital as well as analog base band signal in audio frequency range. Requires modem software for modulation and demodulation of baseband signal.
