Bob and Catherine have retired from the retirement project. Treetop Circuits has ceased production after 13 years and over 700 units sold.

Technical details are posted Build Your Own so anyone can make the units for their own use or to sell. Currently there is enough information to get parts and build the devices. Instructions for alignment and testing, and making the test rigs, will follow.

Email radio [snail] treetopcircuits [period] com -> mailto:radio [snail] treetopcircuits [period] com for technical assistance and to be advised when the next set of instructions is available.
