Hello, As a relative newbie, ( less than 10 years lic. and born after 1968 ) I am perplexed by all the SWL cards I receive. I think it's great, as they seem to have the nicest cards I have received.... but I honestly don't understand the concept. Can someone explain it to me as a simpleton. . I get so many SWL cards that say something like " I witnessed or observed the QSO between you, ( WH2HAO ) and ...... ( whoever) on psk 31. Very nice QSO.. etc... " . So what am I supposed to do, send them a card back and say it was very nice of you to listen in to the QSO, TU 73 sk... or what.?? I mean why does anyone want to listen in to digital Macros conversations, its beyond me. I don't even like to listen to my own QSO's on digital, so what is the point from the SWLer point of view, because I am really missing it..
