I also own very old ICOM IC-240 from late 70’s and with help of service manual I was able to fix it and make new VFO unit for it! One can learn so much by studying their block diagrams and schematics.
#Icom ic f121 programming software manuals#
ICOM service manuals do not stop to amaze me. I was able to program channels to get to my repeater and open VHF channels.ĭownload the software CS-F1600 CD-221501-003 Service manual There are many options related to trunk operation in professional segment and I have almost no clue.
#Icom ic f121 programming software how to#
I consider this abandon-ware.ĭo not ask me how to program X or Y, I still do not know. I think no one will be offended if I mirror it here. Here is a link to one that I found with a quick search: hashitem2eb3488ecc. Most radio software is available on fleabay. I don't recall the latest software version for the 'S' version radios. The correct software for the f121s/221s is CS-F100s. I believe this software was sold by ICOM, but it is more that 15years old (and still works well on Windows 10). The correct software for the f121/f221 is CS-F100. Programming (cloning) softwareĭeep down on the web there was installation files available for download. If some wants ready made cable, leave a comment and I can make it for you.

FTDI and Prolific are often fake chips and driver refuse to work with those. If you do not have this “FTDI” interface, I would recommend buying one with Silabs CP2101 chipset. In the past I hacked together same interface for Alinco DJ-X30 scanner. By looking at the schematic I realized it is simple one wire TTL-UART. Original cable is supposed to be ICOM OPC-592. Service manual with full schematics and programming software is available.Īfter searching Internet back and forth for some information and software i have finally gathered all I need and I will share it here. Radios are very well made, very rugged and probably very reliable. Recently, I have acquired a few professional radios used in taxi service for a good price.
