1. Vol 1 Building a Wireless-Modes Bench — Vol 1: Receive First Every mode in this sub-project can be seen, heard, and decoded for about thirty dollars, with no licence and no antenna worth the name.

2. Vol 2 Building a Wireless-Modes Bench — Vol 2: Transmit, and Five Things to Build The interface between a computer and a transmitter is three components and one principle: isolate everything. Then five projects, from an evening's soldering to a beacon that will be heard on another continent overnight.
