Description

Description

This is a tuning aid, designed to assist in tuning up CW and SSB amateur radio transmitters and limiting the risk of damage by transmitting at a low duty cycle. It is similar to the "Woodpecker" Tuning Aid described in reference [2]. This design is unique in that it includes both SSB and CW tuning aid circuits in a single unit. The design is flexible and can be assembled in different ways depending on what features are needed.
