The Icom IC-7300 uses a USB 2.0 Type‑B port (the square “printer-style” connector) on the rear panel for its computer interface.

Port type and location

  • The jack on the radio is a USB Type‑B female connector, not USB‑C or micro‑USB.
  • It is located on the lower right side of the rear panel when viewing the radio from the back.

How you connect it

  • You use a standard USB Type‑A to Type‑B cable (commonly called a printer cable) to connect the IC‑7300 to a computer or device.
  • Once connected with this cable, the radio presents both a CI‑V control interface and a USB audio interface over that single USB link.

Practical notes

  • No separate audio interface (like a Signalink) is required when using this USB Type‑B port, because control and audio both run over the same connection.
  • Many digital‑mode and control guides for the IC‑7300 explicitly refer to using a “standard A/B type USB cable,” confirming that the radio’s USB port is Type‑B.
