Why didn´t my Funktion Keys work when I used DX4WIN:s RTTY... When I push the F-buttons my trx don´t transmitt! I am using PK232MBX to ICOM IC775DSP. My F1 button is programmed as follows: CQICQ CQ de %^^ %^^ %M Is that a proper string ? Reading RTTY is OK... I belive that you out there have the answer .... 73s de Ben SM3DXC
