Cool thanks! now is that just carrier or is that over all power? im just wanting to change carrier
If your radio has only two wires going to the High/Low switch, you can just take them loose from the switch and connect one wire to the center lug and one to the end lug of a 5k pot.
If the control works in reverse, with high power at the left end, just move the wire from one end lug to the other one.
The original High and Low trimpots should let you set max and min power.

There's the rub, when you reduce carrier - Audio power really climbs.
So they made AM power (VR13 - Carrier) and VR 16 - Audio Envelope - work together to kinda keep themselves on an even Keel.
Once you lower Carrier (AM power) the ability to control the envelope is less - so VR 16 is like a trimmer to handle the Dynamic Range issue the Low to High Power curve presents to the limiter.
What I like is the "dual gang" pots you'd see on Balance controls from old stereos - that gives you the most flexibility of envelope to carrier limits so you don't go "dual sideband - no carrier" at least not without forcing yourself to do so thru those controls. They turn together as a unit and you can hold one to turn the other to make the effect more or less pronounced.

If I run my wires straight from the vr13 location to the potentiometer control knob, do I run the risk of burning out the pot? I want to try this on a ss3900 by using the swr variable control. I thought I read somewhere about putting a resistor somewhere inline? Thanks
