Ted,
I worked the last pass over SoCal from my driveway with 500mW. I had little trouble getting in once it cleared the local obstructions.
Hand guided Elk with VFO Doppler tuning. I think most people have outdated keps so they're way off. I've worked this bird a couple times now and never over 2.5W with 817 as an uplink. As usual, QRO isn't the answer.
73's
