[Lowfer] 6R on 182.868 kHz is on-the-air from El Dorado Hills, Ca

[Bill Ashlock]

Ed,

Nice antenna setup! Using P = I^2 x Rac = 1  (Where Rac is the total ac loss in the system, including loading coil, ground, and nearby tree absorption losses; and I is in RMS antenna current)   Your Rac would calculate to 16 ohms, which is really good for a first effort. Are you sure your 250ma of measured antenna current is RMS current?
