Short and sweet, no, there isn't anything simple you can do to your radio to increase it's power output without a lot of trouble. Sure, you might get a watt or two more out of it, but that small increase won't make any difference. The same thing holds true for an amplifier. To make even 1/2 an 'S' units difference you have to double the output power. For a single 'S' unit, that means four times the starting power. I think you can see where that get's to be sort of huge before very long, right? Wanna do it anyway? Knock your self out! But you're wasting your time and money. Spend that money on a better antenna, it'll go a lot further (pun intended).
