Description

The SK-220 safely acts as an amplifier interface to your modern transceiver to the Heathkit SB-220 or SB-221. This unit is mounted inside the amplifier and transforms the 120VDC key closure to approximately 0.7VDC at 1.5mA.  Without it you run the risk of severely damaging the keying circuit in your transceiver.
