Pah! Watching 20m PSK at the moment, why do so many users send in uppercase! PSK uses varicode, lowercase is *so* much faster. PSK63 + Uppercase seems to defeat the aims of the game.
Really it's down to the programmers - let's make the users aware that lowercase is sent much faster. I do this in my Macro Editors. I guess we could add a small option to show the efficiency of the user's input - as-is versus all lowercase. FWIW I had a QPSK-125 QSO with RW3DQC - QSO was over before I realised what was happening, he's an excellent operator! Simon Brown, HB9DRV
