Hendrick's QRP Kits in the USA have just introduced a nice little regen receiver kit for beginners and more experienced hams and SWLs. The Scout is a simple 2 band regenerative receiver covering from 3.5 -11MHz. It is based on the classic design by Charles Kitchin published in QST some years ago. It is to be launched at Dayton and on sale from May 12th.
