We tend to think of loops as ground-independent, but the way signals are reflected is hard to know. Gary may be getting a boost from signals bounced off your hill, assuming the phase is correct. On your poorer soil, a Beverage antenna should work better than down in the fertile valley. But the way trans-polar signals get skewed, you'd need a few to be sure you were on the right bearing. Look at the bright side. When sea levels rise in a few decades, you'll both have oceanside locations! 73, Jim, KR1S http://qrp.kearman.com/
