HK-1B keyer built by Hammarlund in 1966.

The unit is visible on the right side of the photograph and is the only purely solid-state gear in the shack with four 2N404 transistors that originally were Industro TR-901s. The HK-1B is also the youngest equipment (other than a modern SWR/Watt meter) in the shack.

The HK-1B is keyed with a Vibroplex paddle.

See the qsl.net site for additional information on the HK-1B keyer.
