I need to know what is the stock dead key on low setting for RCI-2990 / galaxy saturn turbo
I know the high setting is 50 watts swing to 150. What is low?
Thanks
 

Low power carrier setting on these radios is 10 watts. Problem is the lower the carrier the more negative peak cutoff you're going to get because of the low output voltage from the series pass modulator.

It gets so bad around or below the optimum carrier range of 25 watts that you can't approach 100% positive peaks before RF cutoff. An improvement can be seen adding a 10 ohm resistor between the driver and final. This is outlined in another tread in this category.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
