You don't say how much power you are running, but it must be quite a bit, or you have an amp you're not telling us about. By keying up the radio, you're putting enough load on your electrical system to pull the voltage down which causes you lights to dim, rpms to drop, etc. When you key off, everything goes back to "normal" which means no load so the engine will surge momentarily before it recovers. Depending on how many watts you are running, you may also be affecting the alternator regulator. Your alternator may also be a little weak.
