                                                 STANDARD  C160
                                                    EXPANDED RF


1.  Remove battery and antenna.
2.  Remove screws and open the case. Be careful, do not break flat cable.
3.  Locate microprocessor.
4.  Install a DA-113 chip diode in place. [ A 1N914 ]
5.  Reassemble the radio.
6.  Reset the microprocessor. [ Check owners manual

 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.168S

Remember it is Illegal to transmit out of band. This Modification is for Informational purposes ONLY.
Doing such modifications on your radio may void any warranty and damage your equipment.
All mods found on this database are offered to me by other amateur radio hams or captured by Packet system. 
KB2LJJ  take no responsibility or liability for any damage done resulting from any modification.  

 I have been trying to help our ham radio with the radio modifications and have asked for any type of new radio mods.
 However, I haven't received too many.  If all of you contributed a little more,  I believe I would be able to help 
all the other ham's that are looking for these mods. I know it is possible to get more mods from all the Ham's because of
 the wide range that exist throughout the world.  By doing this we can  flourish and enjoy more of this hobby that 
we've taken part in for so many years. Furthermore, I ask you not to forget to send me any modifications that you might
 have through email.  I would really appreciate it.
