Each year Ham Radio Workbench designs and produces projects that get Hams building again.  We publish all the material needed to purchase, assemble, test, and (where applicable) program our projects.  We manufacture and sell Printed Circuit Boards and leave the sourcing of components up to the customer figuring that lots of parts used are likely to be in your junk drawer.  Our projects utilize through-hole components wherever possible to make assembly a breeze.  Whether you are new to soldering or an experienced kit builder, our projects ​will result in useful items in your Ham Radio adventures whether in the shack or in the field!

At this time, we are only offering shipping within the United States.  If you are interested in placing an order from outside the United States, please contact us to see if we  arrange something to meet your needs.  As we are getting started, shipments may take up to 3-5 days to occur.
