[Elecraft] KPA500 Clicks & Pops

[Wes Stewart]

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.
