[DX] last 2 and CW

Wed, 30 Oct 2002 13:29:28 -0800

John,

you didn't get it quite right! You use the last 2 when the DX station says
QRZ after every contact and does not find it necessary to give his own call.
The idea is to get his attention and make a contact without either station
ever knowing who they just worked.

Jim, AF6O
