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) /===\ +----+ +----+ + + /---\ +-||-+ +-||-+ | +---+ +---+ | | || ||

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 73 de YO3GGH !
