Pappy and I just did some tests with our radios. He was using a Yaesu FT-7800 with a Comet 3.8 db Gain antenna, and I was using a Yaesu HT VX-170 (5 watt) with the standard (I presume 0 db) antenna. On the first try from his house I got him at 65 watts (full power) with 1-2 (of 10) bars, and on the second where he climbed up to the mesa on Unser I got him at full power with 2 bars. These are along the profiles below, with significant dirt in the way. He got me loud and clear on the Sandia Megalink repeater, which is 9 miles from me.
