Quick video on how to tune up an SB-200, and IC-7300, when using a manual tuner. Also some information on using the Kenwood SM-220 to monitor SSB envelope and check linearity with the trapezoid display. My antenna is an 80m loop at 15ft height, and I am also using a Heathkit SA-2040 manual tuner with an Ameritron ARB-704 amplifier interface.
