USB-RTS05 vs. USB-29A
The USB-29A cable (blue) programs the radio. It connects to the radio through the 3.5mm speaker jack. If there are two speaker jacks, it is usually SP2. Check your manual. It will specify which speaker port is used for cloning or programming. That’s the one to use.
The USB-29A cable is generally more dependable for programming since the radio does not put other data out through the speaker jack. However, you cannot have a speaker attached to the other speaker jack while programming.
The USB-29A cable can be used to program many of the Icom handhelds and mobiles as well as radios from other manufacturers. It is one of the more “universal” programming cables in the RT Systems line.
The USB-RTS05 cable programs the radio through the 2.5mm data port.
The USB-RTS05 cable works both for programming the radio with the RT Systems software AND as a cable for digital data using other programs such as D-Rats. It works with many other Icom D-Star radios (handhelds and mobiles) for programming and data.
Note: Be aware that you must turn off GPS from the controls on the front of the radio when using this cable for programming. Erratic movement of the mouse will occur if GPS is on.
