While the stock receiver can copy AM shortwave broadcasts, the introduction of the UI-7 ensures full, stable integration of all mode squelch functions. This makes scanning across broad spectrum lines cleaner when seeking local AM or FM signals.

: A dedicated connection (often a brown wire) must be linked to the front panel assembly (J5) to activate the mode-switching button. Current Availability

Once installed, the UI-7 fundamentally changes the operating characteristics of the transceiver. According to Icom's documentation for the IC-725, here is how the performance changes: Transmitter Performance (e.g., IC-725) The radio will transmit 100 watts on FM.

When you engage the AM or FM mode with the UI-7, don't expect the "high-fidelity" of a commercial broadcast station, but do expect solid communication quality.

Checking the "parts" bins at local amateur radio swap meets.

It provides standard narrow-band FM (NFM). It is perfect for 10-meter repeaters or 6-meter FM (on the IC-726).

Switch to AM . Tune to a strong local mediumwave (AM) broadcast station. Compare the audio with the board installed versus your memory of the stock configuration; you should notice a cleaner, more robust audio profile with less clipping on signal peaks. Troubleshooting Common Issues:

The UI-7 is a hardware PC board that installs inside the radio chassis. Once installed, it enables the radio to function as a high-quality AM/FM broadcast receiver alongside its amateur transceiver capabilities.

. Note that similar later models, such as the IC-707, utilized a different version called the UI-9. Integration:

Whether you are dealing with a like low volume or distortion.
