and [C] under the display while turning radio back on. The radio will emit a series of beeps and enter the hidden service menu mode. CAUTION: DO NOT MAKE ANY ADJUSTMENTS TO ANYTHING IN THIS MENU WITHOUT FIRST COPYING THE DEFAULT SETTING! THIS IS A SERVICE MODE AND THE SETTINGS ARE UNIQUE TO EVERY RADIO. Advance to menu item #60 which is the AM carrier level ALC control. The display should show something like: AM-CAR-LEVEL 125 AM 21.225.13 Note that the value of 125 is unique and will change from one radio to the next. Mine was set to 142. While monitoring the ALC level press the PTT and adjust the main tuning knob for little or no ALC indication. This will allow the carrier to peak to something near 100-120 watts like it should. I had to set my radio to 96. The problem is that the factory settings limit the carrier to 25-30 watts and the ALC will not allow it to peak any higher as it should be able to do. After making the adjustment press the [FUNC] button again to exit the setup for that menu item and turn the radio OFF. Turn the radio back on normally and enjoy MUCH better quality AM transmissions. I find it best to not use the processor or if you do use very light processing on AM. You may also find it useful to set the radio to use the DSP settings for TX as well as that allows you to tailor the high and low limits of your audio. Prior to making this simple change I had very muffled audio on AM. After, I had MUCH improved audio that was no longer muffled and the power meter actually moved with modulation. Above all keep the carrier to no more than 25-30 watts.
