The MMTTY/EXTFSK combination can use DTR on a serial port for FSK keying, but I have no idea whether EXTFSK would work through LP-Bridge. Without EXTFSK, MMTTY uses TxD for FSK keying, not DTR, and that cannot be shared with radio control.
If you are already using MMTTY, by any chance does that mean that you have an audio cable from the K3's LINE OUT to your computer's sound card? If so, a second audio cable from the sound card's output to the K3's LINE IN is all you need to do AFSK RTTY. The K3's AFSK RTTY is just as good as its FSK RTTY, so there is no reason to insist on FSK. 73, Rich VE3KI PA3A wrote: > The idea was to use LP bridge. > Send the RTTY keying via a com-port from MMTTY, and control the rest of > the K3 via another com with N1MM logger.
