That happens to be the same trace as MIC GND.īaofeng Interface complete Building from existing Digital Station setup from past posts For the second jumper, solder one end of a jumper wire into PTT HI and the other end to the open pin on the left bottom of T2 and above the left side of R2.Snip the pin from the other end of that jumper wire and solder the wire to the side of C2 closest to PTT GND. For the first jumper, solder one end of a jumper wire into PTT GND.We accomplish this by adding two jumpers to the component side of the board. Triggering PTT on the Baofeng requires AUDIO, PTT, and MIC grounds to be connected together.While verifying which wire from the Baofeng Speaker/Mic cable goes to what tip or ring on the connector, solder the Baofeng speaker/mic cable to the board as follows:.We will not be using the ring connection since audio from the radio is mono. From the top of the board looking at the AUDIO TO PC stencil with the other 3.5mm cable half, solder the audio shield to the hole on the left side of the stencil and the tip to the hole on right left side of the stencil.We will not be using the ring connection since we only need one channel of stereo audio to the radio From the top of the board looking at the AUDIO FROM PC stencil with one of the 3.5mm cable halves, solder the audio shield to the hole on the right side of the stencil and the tip to the hole on the left side of the stencil.Use one half for USB audio from the board and the other half for USB audio to the board. Cut the 3.5mm stereo male-to-male cable in half.Solder the Easy Digi kit components to the board per the instructions provided by the kit.Once I had all the materials the build went as follows The materials are not perfect but for $2 USD and a glue gun for filling gaps it keeps things contained. After working with candy containers and cigarillo tins I found the cheapest case to build has been plastic electric outlet boxes and covers from home improvement stores. It is not until I have something working (consistently) and need put it in something less precarious than sprawled across my bench that I figure out enclosure options. My quest for the”quick win and taste of success” never includes what will I do for a case to put everything in. 2 Male-to-Male Jumper wires ($5 USD for a bunch).
