Nice work!  I used to use around 200-250mW on UO-14 from time to 
time, when that bird was operational, and had no issues getting in at 
that power level into a 2 element Yagi.  Haven't tried anything 
lower, because that's as low as my radios would go.  Today, the 
lowest power I could manage is around 500 mW.  Besides, the antenna's 
not back on the air, I have to replace a couple of dodgy SMA-BNC 
adapters that don't fit the radios. :(
