Conclusion 
 

We hope you had fun with this kit and that you enjoy many hours of operation with this 

transverter.  The goal of this kit was to economically provide the radio amateur with the highest 
performance available in a 23 cm transverter while maintaining a compact and portable design. 
 

We wish you years of fun and excitement working many contacts both local and DX! 

 

 

 

   Good luck on the band!
