Todd, that sounds like a "noisy" pot in which the wiper isn't making good contact with the resistive element inside. When you touch it, the circuit opens briefly, which is the same as turning the RF Gain all the way to minimum. That will cause the S-meter to read full scale. The delay returning to normal should be the AGC decay rate. If you tap AGC to switch to FAST, it should recover much more quickly.
One fix is to put a few drops of a control lubricant on the control shaft with the rig standing front panel upward so the lubricant will run into the pot. Turn it a number of times to work it down into the resistive element. I use Caig DeOxit for that. It comes in a small squeeze bottle with a hollow needle applicator. Recommend you avoid any sprays. They get stuff all over the place. If a spray is all you have, recommend you spray onto a small screwdriver shaft or length of wire it to collect drops of liquid on the wire or screwdriver shaft. Work away from the rig with a towel behind the sprayer to catch the overspray. Then position the wet wire or screwdriver shaft so the drops run down onto the pot shaft and into the pot itself. If it's a stubborn case, you may need to replace the pot. Ron AC7AC -----Original Message----- I just noticed that whenever I touch my RF gain control knob for adjustment the S meter jumps completely to the right and VERY slowly drops to whatever level of RF gain I have set. It takes several seconds for the receiver to come back to the point where it can receive again. I have used other K2's and this has not been the case. Can someone else tell me if they see this happening. I probably haven't explained this very well but would be glad to explain this more if needed.
