How to update your IC-7300 to the latest firmware?

Short video showing the steps in the firmware upgrade process of the Icom IC-7300 HF radio. Make sure you read section 15 of the full owner’s manual before/before attempting this upgrade.

New technology is changing the way receivers are being designed and the IC-7300 is an industry first as an RF, Direct Sampling System is being used in an entry level HF radio. The ability to digitize RF before various receiver stages reduces the inherent noise that is generated in the different IF stages of a radio. We feel the performance of the ‘7300 will far exceed your expectations for a radio considered entry level.

Output power:		100W (25W AM)
RX Frequencies:		0.030-74.800
Receiver type:		Direct sampling

RF direct sampling system

The IC-7300 employs an RF direct sampling system, where RF signals are directly convert to digital data. Then processed in the FPGA (Field-Programmable Gate Array), making it possible to simplify the circuit construction as well as reduce noise that can mask weak signals.

The new “IP+” improves the 3rd order intercept point (IP3) performance improving the ability to copy a weak signal that is adjacent to either a strong interfering signal. In this process, A/D converter is optimized to reduce or eliminate signal distortion.
