Tony Castellano, W1ZMB recently worked Hawaii using his Elecraft K2 running 100 Milli Watts (0.1 Watts) CW to his OCF Dipole. This equates to 50,000 miles per Watt. To equal this, if one was running one Killo Watt, he would have to make a contact 50 million miles away. Tony operates only CW and never more that 5 Watts. Since building his K2 5 months ago, Tony has worked 134 countries and all continents running CW QRP to his OCF Dipole.
