. Note that the Icom IC-726 already includes these features and does not require this board. Internal Placement
While the stock receiver could often listen to broad AM shortwave frequencies, the UI-7 allows operators to transmit in AM mode with up to 40W of power. This is ideal for participating in vintage AM nets on the 10-meter or 40-meter bands.

The is an optional internal expansion board designed to add AM and FM transmission capabilities to classic Icom HF transceivers . While many of these radios feature AM and FM buttons on their front panels by default, they often require this physical module to actually transmit in those modes. Core Functions icom ui7 am fm unit
If you search for "AM FM unit" online, you will find hundreds of cheap automotive options. So, why pay a premium for the Icom UI7? The answer lies in three distinct marine realities:
Disclaimer: Vintage electronic components are sensitive to Static Electricity (ESD). Always ground yourself before touching internal radio boards.
Wide AM (Amplitude Modulation) and Narrow/Wide FM (Frequency Modulation). This is ideal for participating in vintage AM
Whether you are restoring a classic rig or buying the latest handheld, Icom's commitment to AM and FM excellence is clear. Each device offers a unique window into the auditory world around us, from the quiet hiss of a distant shortwave station to the crystal-clear tones of a local FM rock anthem.
