Relive the days when Amplitude Modulation (AM) was the main communications mode!

 
The name, 'Nouveau 75', is a nod to the legendary 'Retro 75', AM transceiver designed by Dave Benson, K1SWL. Since production of the Retro 75 ended, there have been no AM QRP kits available to take its place. This new kit was designed to fill that market niche..
 
The Nouveau 75 is a 75 Meter, QRP AM voice transceiver produced by the Four-State QRP Group. This design is simple, yet full-featured, efficient, and easy-to-build. This kit utilizes a hybrid construction, with about 80% of its components pre-installed surface mount devices. The remaining components are large, through-hole connectors, controls, and power devices. The kit includes a pre-drilled, silk-screened enclosure made of PCB material. The finished result is an attractive, functional radio that is easy to assemble and operate.
 
ALL THROUGH HOLE parts make this kit very easy to assemble. It will make a fine, fully functional, and educational first rig for a new builder, the new ham, or seasoned veterans wishing to just have fun with a new rig at minimal expense and effort.
 
 
Clubs and Groups Please Note! Group discounts are available, 5 kit minimum order required. Contact the kitter at the email address below.
