True, but what I'm referring to is just the deadkey /swing ratio. This is set by the user by the RF power knob. If anything I've gone in and simply found a balance with the high and low power pots and the RF knob to achieve a 4:1 ratio. I usually had good luck right out of the box having the radio near the peak rated power requiring only a deadkey setting that was in range if the RF power knob.
I have found with new radio's the AMC pot was way low that's why I mentioned this earlier. A real low AMC will affect the modulation power so I usually turn this up.
As for alignments, to me that's more involved like having the TX and RX on frequency amoung other things. Most if not all these CBs and exports are off some especially on SSB. One quick listen on 38 LSB and you can hear radio's all over the place.
So I also mean on those alignment adjustments, if you don't know what you are doing and don't have the proper equipment, leave it alone.
And, on nicer radio's like the 2900 series models, don't do the typical hack mods on it. Save that for the Galaxies or Connex's.
For the most part, the RCI2900 series are good radio's especially if you are a SSB user. A few simple adjustments were needed with mine but that's it. No need to try and squeeze a couple more watts out of it because that can cause IMD, excessive heat, and damage to the finals and makes not one bit of difference on the other end.
