Today I tried "IM" with no effect. I do RTTY with my CW-paddle and in the test-mode. I gave my callsign "DL1EK" and than "IM" as one letter, like the german "Ü" (di-di-dah-dah) buat the idle gos on for the usual 4 seconds. Did I understand something wrong or did I make a mistake? Thanks for helping. vy 73 Karlfried, DL1EK
