Ed,
Not picking on you personally either but I fail to understand this attitude that
because some digital mode or another can make QSOs with 10 mW on some path,
everyone else should run only10 mW.
I consider my K3S + KPA500 to be a 500W transceiver (with push buttons for
selecting bands) and that's the way I run it. Often, especially when I'm
beating myself up on 160, I wish for more power. When some of my DX club buddies
tease me about running QRP should I ask them to lower their power so we have parity?

ps: When I ran 2-meter EME 30 years ago we actually heard the signals by ear.
