  • Notes
  • The Rider's schematic 10-8 has been drawn Sept. 26, 1935 and shows the same schematic for M-41 and M-43. This family uses 3 tuned IF filters. Oscillator is the tube 56. The 55 is the diode detector incl. for AVC. Four different bands are reached by rotary band switching: BC 194 - 555 m, 72.4 - 216 m, 32.3 - 96.2 m and 12 to 33 m. Tone control, calibrated 2-speed dial. Push-pull output. Sensivity is better than 2.5 microvolts per meter with 10 kc selectivity.
