The Ozark 17 is a CW transceiver kit for the 17 meter band. It features a VXO controlled superhet receiver and a separate VXO controlled transmitter, often called an RXTX rig. This design has built in RIT. Power output is approximately 1.5 watt. Both the receiver and transmitter are built on one single sided pc board. The design features excellent sensitivity and great performance. If you ever wanted to get on 17M with a QRP rig, the Ozark 17 will get you there nicely. The sidetone is heard through the receiver when transmitting, so just line up sidetone with the frequency of the station to be called and fire away. The receiver features a low noise front-end on Hi IP mixer. The kit employs mostly through hole parts, with only two ICs. Only the diodes are non-SMT parts, they are large and easily soldered.

This is a difficult kit designed for very experienced builders. We do not recommend this for the beginning or average builder.

Clubs and Groups Please Note! Group discounts are available, 5 kit minimum order required.
