For decades, 14.195 was the "unofficial" 20 Meter DX calling frequency, but lately it seems every knucklehead LID (and their brother) want to claim it as just another 20 Meter SSB frequency. Of all the 20 Meter spectrum you can use to ragchew about you Macintosh computer with some Kentucky redneck, why pick the one frequency that hundreds (if not thousands) of Hams worldwide still monitor? Just about every DXpedition and rare DX station under the sun has used (and continues to use) 14.195, so can somebody explain to me exactly when and why we've given up 14.195 to non-DX ragchewing?
