Well you could have the AM power tuned down and the modulation turned up as well and you could possibly see that kind of power as well Matt. Not saying the radio doesn't have a swing kit as it may very well have one. Check for a cap and resistor close to the final. There will be a cap on the top side and normally a resistor on the solder side of the board near the final. Hope this might help a little. Have a good one. And let me say it now. I am in no way a tech nor do I claim to be. Just throwing some possibilities out there as to what could be. Again, hope it might help. Good day.
