[CQ-Contest] Handicap For Dirty Rigs

[Robert Chudek - K0RC]

And just where should all these "less than desirable" rigs end up? They 
are certainly going to be put back on the air someplace. Maybe they 
should go into a landfill? It sounds like another "Cash for clunkers" 
program to me, but this time it's for radios instead of cars.

"In a perfect world..." :-)
