Rejector Circuit Board, Type SE-3523, 1918
01
Artifact Overview
In radio's early years, as airwaves grew more crowded, amateur operators and commercial transmitting stations alike were frustrated by static interference. Interference was human generated or atmospheric; common culprits included proximity to AC power lines or overlapping transmissions from multiple stations. The rejector circuit board diminished and eliminated
unwanted, intrusive wireless signals, resulting in clear reception of a desired channel.
