Microwave construction is surprisingly popular--hams love to explore new frontiers!  While rarely easy, many adventurous hams are up to the challenge of building equipment for our highest amateur bands. There are ways of getting around the expensive test equipment issue, such as building equipment pairs  or joining a nearby club and getting help from the local  experts.
