![]() * get the bits or find someone to reprogram your icom You need to run a loop of copper wire around the barrel of the programing lead and touch that to the earth of the microphone socket during reading and writing One thing I do remember about the F22S is that the most common fault when trying to re-program them is that the earth breaks on the earphone socket through repeated (ab)use which prevents programming. I may have a copy, but my radio programming PC has suffered a catastrophic hard disk failure and getting a copy back from the disk image will be like pulling individual blades of straw from a bale of hay! I think the programming lead is called an OPC-8 but don't take that as gospel - it IS however the same one as used on the T8E ham radio handheld The software ( I think is called CS-11 or CS-12. ![]() The interface lead plugs into the earphone socket and into the serial port on ![]() Radio, black, with CTCSS only? hope thats right - haven't had my first coffee of the day yetĪssuming I have the right radio in mind, There is no way to re-program or reset these other than by re-programming the radio using a PC & interface lead I'll have to look up the F25 but from memory the F22S is a UHF 16 channel There are other users of this forum with much more knowledge than I have and may be able to assist you further. ![]() To complicate matters further the radios could all be on the same frequency but still not communicate with each other as there are ctcss and dcs tones that either have to switched off or all be same on all the radios for them to communicate with each other. The other radio has been set to work on different channels or is faulty perhaps. Saying that a lot of people (our family included) use higher power radios with more efficient antennas on the PMR446 frequencies.Īt some time someone has most likely programmed the F22 with some or all of the PMR446 frequencies and so can 'talk' to your sons radio. The ICOM radios you have purchased will not strictly be legal for use on PMR446 as they have a higher power output and removable antennas and are designed to be used on different frequencies (channels) that you need a license for. ![]() PMR446 is a license free service using 8 specific channels with radios transmitting with a maximum of 500mw power output with set top fixed antenna. ![]()
