May not work with IC-9100 without MORE hardware

The ICOM IC-9100 allows adjustment of the CW tone pitch, also known as the sidetone frequency, but its adjustable range is typically 300 Hz to 900 Hz, or possibly slightly higher depending on the specific firmware version. It does not appear to support a 1300 Hz tone through the standard user controls or menu system, as this is outside the design specification for the user-adjustable range. The sidetone frequency in Icom radios also often determines the receiver's offset frequency in CW mode, meaning your displayed frequency will be offset from the actual receive frequency by the set pitch. If a 1300 Hz tone is absolutely required, it would likely involve using an external audio tone generator feeding into the radio's audio input, or potentially using an external signal processor with a wider filter bandwidth, but this is a complex setup beyond standard operation. The built-in functions are limited to the 300-900 Hz range.
