“I can only guess how much power it will take to get the 15,000uv/m at 30m”
It wont be 1.2 watts, somewhat lower. BTW, its 10,000uV/m @30m (15.225), and 30uV/m @30m (15.209).
If you cannot locate a suitable meter to check for legal field strength, you might check with a local radio shop and see if one of their guys might help you out to measure this. They usually have adequate equipment to do this. May not be a fancy Potomac, but their IFR’s or Moto’s most likely will be more than accurate enough for this measurement.
Or an even simpler method is to go out to 30 meters from your antenna and your signal should just barely be above the noise floor level, and further from that point it should steadily dive into the noise floor.
