Connecting President Washington (CB) to Digirig for JS8Call

[K0TX]

Erwin,

It appears that Washington model shares the same mic pinout as Lincoln. There is no off-the-shelve cable for either, but the pinout was discussed in this thread:

Cable for President Lincoln 2+

[image] Based on the above mic schematic, the audio cable for Digirig will look like this: GX??-6 pin 1 (Modulation) → 3.5mm TRRS ring 1 (RIG_AFIN) GX??-6 pin 3 (TX) → 3.5mm TRRS ring 2 (RIG_PTT) GX??-6 pin 5 (Ground) → 3.5mm TRRS sleeve (GND) 3.5mm TRS tip (Ext. Sp.) → 3.5mm TRRS tip (RIG_AFOUT) Connection GX??-6 pin 2 (RX) → GX??-6 pin 5 (GND) may also be required. Please report your results if you give this build a go.

Please post the update if you decide to give it a go.
