Eric,

With 99.75 mw input I measured 78 ma antenna current on the 510.510 khz
beacon.  With 100 mw input on the 1704.983 khz beacon I measured 98 ma
antenna current.

This was measured with Lyle's current probe design which I tested at 180 kc
and found to be dead on with his published current charts.  I have not tested
the probe at MF but per Lyle's comments the probe is good up to 10 MHz.

A picture of today's Hi-Medfer antenna current measurement can be seen at:
