Make icom IC 746 pro general coverage all band

0

1 comments:

Mr. Anderson

February 20, 2025

The Icom IC-746PRO provides general coverage reception from 0.03–60MHz and 108–174MHz. However, specifications are only guaranteed for 0.5–29.99MHz, 50–54MHz, and 144–148MHz. To enable general coverage, select the desired band using the keypad above the tuning knob and then use the tuning knob to adjust the frequency as needed.
