arrl.org/rookie-roundup 1800 to 2359 today! Look for rookies calling CQ RR on the "50s" - 50 kHz above the band edge. If a non-rookie calls CQ, call CQ R. Exchange is name, check (like in Sweepstakes), and state/province/Mexican state or "DX". Not much on 15 at the moment, but 20 is busy. 73, Ward N0AX
