A PCB containing a DVSI AMBE-3000R (or AMBE-3003) Vocoders for use with WebSDRs/Audio transcoding.
This board is based on the design by George Smart, M1GEO and Chris Smart, G8OCV.
The DVSI AMBE parts can be purchased in low volume from the DVSI Inc. Hardware Product Pricing page. You will need to create a purchase order to buy from DVSI.
The design schematic include details for JLCPCB assembly, who assembled mine. You'll likely have to reflow the DVSI AMBE-3000R part yourself, which I did with a PCB reflow hotplate, but you can do any way you wish.
Each schematic component has a JLCPCB Parts/LCSC part number (Cxxxxxx), which can be exported to the BoM using the extra field "LCSC".
