The modifications of Standard C160/168 for frequency spread and AM mode
  -----------------------------------------------------------------------

  When you buy your C-160 you can only Rx-Tx strictly between 144-146 MHz
  and only FM. Frequency shift is also blocked (why?). At least European
  models are like that.

  To enable full features for your RIG:

  - 57-392 MHz receive AM/FM (with some gaps 98-100, 177-210)
  - 122-177 MHz transmit FM
  - repeater using any shift

  you have to desolder an SMD transistor and resolder it as a diode.
  Handle with care because the SMD is small and the operation is rather
  delicate.

  Below is a diagram to do this (I hope it wouldn't be a problem to
  understand it but this medium is fairly restrictive for graphics).

  You'll have to reset your RIG after the modification
  ( F + 0, F + 3, F + 0, F + 1 )

  New available functions:

  - Toggle AM/FM mode: F + 0, F + 2

  - Toggle input frequency starting with 100/1 MHz order: F + 0, F + 0, 8

  I'm using a Standard C160 with this mod and I am very satisfied with.
