  • Model: World-Wide T-100MD - Panasonic, Matsushita,
  • Shape
  • Portable set > 8 inch (also usable without mains)
  • Notes
  • The National Model  T-100MD is a World-Wide, 4-Band FM-AM portable radio.

    It features dial lamp, AFC, MPX and ext. amp jack, ext. FM ant in, tuning/batt. meter, bass & treble control, fine tuning, and earphone jack.


    The specification are similar to the T-100, except:

    • FM-AM 4-Band 12-Transistor 5-Diode.
    • Telescopic antenna instead of the frame loop antenna.
    • Frequency range: 
      • FM: 87 - 108 MHz
      • AM: 525 - 1605 KHz
      • MB: 1.6 - 4.5 MHz
      • SW: 5.9 - 18.0 MHz

According the the paper label glued to the inside of the battery compartment door of the T-100MD model, the transistor configuration is the same as seen on the T-100Y model variant. Here is the listing:

  • TR1    2SA241  FM RF AMP
  • TR2    2SA71    FM MIX
  • TR3    2SA71    FM OSC
  • TR4    2SA70    AM OSC
  • TR5    2SA70    FM 1ST IF & AM MIX
  • TR6    2SA70    FM 2ND IF & AM 1ST IF
  • TR7    2SA70    FM 3RD IF & AM 2ND IF
  • TR8    2SB173  1ST AF
  • TR9    2SB173  2ND AF
  • TR10  2SB175  3RD AF
  • TR11  2SB324  OUTPUT
  • TR12  2SB324  OUTPUT

We would need to find a circuit diagram for the T-100MD to know about the rest of the semiconductors in use (diodes).
