Yes, wide sweep from 1000KHZ to about  7000KHZ  Had to drive the ground rod a few times.  My last estimate of removal wire resulted in the wire "too short' Had to add wire. Had enough  of driving, and removing ground rods.  Was one that wedged in the ledge rocks and is still there.  73

Bruce, Did you sweep from say the AM band up to 40M to find the null? Was the null pronounced? I assume as you shortened the wire you hooked up to a terminating resistor and repositioned the ground rod? Tnx N2TK, Tony -Original Message- From: Topband

I used to use AM broadcast stations to do a sanity check on my beverages. Especially the higher end of the band performs similarly to 160 meters, pattern wise. Rick N6RK _ Topband Reflector Archives - http://www.contesting.com/_topband

I took a hint from Luis HC1PF. A small 1.8+/- clock oscillator and a wire attached to a pole is what he used. I found said oscillator on eBay. It worked, but I am not sure the near field results should be taken for granted. 73 Art NK8X p.s. Still trying to figure out the computer problem that
