From 9 a.m. Saturday morning until 11 p.m. I recorded and processed John's WOLF transmission about every half hour. The only period that WOLF did not provide perfect copy during each 27 min run was from just after 4 p.m. until just after 6 p.m. Copy was actually better during the mid day hours than at night. Not bad for 1 watt, a tx loop and 670 miles! W4DEX
