• The Motorola model XT1BY is an AC/DC operated 4 transistor AM radio. AM Tuning Range: 535 to 1620 kHz. Has Qty(1) PM 4" speaker and built-in ferrite antenna. Cabinet is plastic with white front and yellow cabinet back.

  The following models use the same schematic and cabinet but have different cabinet back colors:

  XT1BY	Yellow

  This model uses the same HS-7201 chassis as used in the Motorola XC11B series of radio's, thus the schematic in Beitman Volume 26, 1966 page 59 can be used as the schematic reference for this model.
