Up Walky Talky

Walky Talky is a similar means of communication that we can use to talk long distance with other people. Walky Talky Tantu just made this one pair.
Components needed:
  1. Transistor (TR) 1 = 2SA102
  2. Transistor (TR) 2 = 2SB75
  3. Condensator (C) 1 = 30uF
  4. Condensator (C) 2 = 470uF
  5. Condensator (C) 3 = RFC
  6. Condensator (C) 4 = 0.002 UF
  7. Resistor (R) 1 = 47ohm
  8. Resistor (R) 2 = 470Kohm
  9. Resistor (R) 3 = 10Kohm
  10. Resistor (R) 4 = 22Kohm
  11. Resistor (R) 5 = 22Kohm
  12. Resistor (R) 6 = 220Kohm
  13. MF 1 = coil 1K
  14. MF = 2 twist 20K and 2K
  15. MF 3 = Purchase of common use
  16. RFC = size-free
  17. Loudspeaker (LS) = 8ohm
  18. Trimer 1 = 30pF
  19. Trimer 2 = 30pF
  20. Bateray = 9 - 12volt
